    Marketplace Seller Agreement

    Last updated: October 25, 2026

    1. Scope and Acceptance

    This Marketplace Seller Agreement ("Seller Agreement") governs the relationship between you ("Seller", "you") and Castellum - Forge s.r.o. ("Platform", "we", "us") when you use the Citadel TCG marketplace to list and sell physical trading cards, sealed products, or other permitted items. This agreement supplements the general Terms of Service.

    By creating a shop or listing items on the marketplace, you agree to be bound by this Seller Agreement and all applicable laws, including the Digital Services Act (EU) 2022/2065, the Platform-to-Business Regulation (EU) 2019/1150, and applicable consumer protection laws.

    1.1 Nature of our services

    We provide an online marketplace and related technical and payment-instruction services to both buyers and sellers. This Agreement is a contract for platform services not specifically regulated by law. We are not your commercial agent: we have no authority to negotiate or conclude sales on your behalf, we are not obliged to promote your items or to find buyers for you, and sale contracts are concluded directly between you and the buyer (section 7). We act in your name only to give Stripe the instructions listed in sections 6.4, 7 and 9 and to operate the withdrawal function under section 9; for this limited purpose the provisions of the Slovak Commercial Code on the mandate contract (§ 566 et seq.) apply if you are a business, and the provisions of the Slovak Civil Code on the mandate contract (príkazná zmluva, § 724 et seq.) apply if you are a consumer. The provisions of the Slovak Commercial Code on commercial agency (§ 652 et seq.) do not apply to this Agreement. Our commission is a fee for the use of the Platform and is not remuneration for negotiating or concluding sales.

    2. Seller Account and Verification

    2.1 Account Requirements

    To sell on the marketplace, you must:

    • Be at least 18 years old or the age of legal majority in your jurisdiction
    • Have a verified Citadel TCG account
    • Create a shop through the platform
    • Complete Stripe Connect onboarding (identity verification and payment setup)
    • Provide all required identification information (see Section 2.2)

    2.2 Identity Verification (DSA Article 30)

    Before you may list items for sale, we are legally required to collect and verify the following information, in accordance with the Digital Services Act:

    • Your full legal name (or company name)
    • Your address
    • Your email address and telephone number
    • A copy of your identification document (processed by Stripe)
    • Your payment account details (Stripe Connect)
    • If you are a business: your trade register number and VAT identification number
    • A self-certification that you will only offer products that comply with applicable law

    We will verify this information using Stripe's identity verification and, where applicable, publicly available databases. If you fail to provide the required information, we cannot allow you to sell on the platform. We will re-verify your information at least once every 12 months.

    3. Seller Types

    3.1 Professional Sellers (Businesses)

    If you sell as a business entity (company, sole trader, or professional), you must indicate this during shop setup and provide:

    • Company name and registration number (IČO or equivalent)
    • VAT identification number (if VAT-registered) — we verify this via the EU VIES system
    • Business address
    • Trade register entry details

    Professional sellers are subject to full EU consumer protection obligations, including the right of withdrawal, legal guarantee of conformity, and pre-contractual information requirements.

    3.2 Private Sellers (Individuals)

    If you sell as a private individual (not in the course of a trade or business), you must indicate this during shop setup. Private sellers are not subject to the same consumer protection obligations as professional sellers.

    Important: Your seller type is displayed publicly on all your listings. Buyers are informed that different consumer protection rights may apply depending on whether the seller is a professional or private individual, in accordance with the Omnibus Directive (EU) 2019/2161.

    4. Tax Reporting (DAC7)

    Under Council Directive (EU) 2021/514 (DAC7), we are legally required to collect and report certain seller information to the Slovak Financial Administration (Finančná správa SR) annually.

    4.1 Information Collected

    • Your name, address, and date of birth (individuals) or company name and registration number (entities)
    • Tax Identification Number (TIN) and country of issuance
    • VAT identification number (if applicable)
    • Financial account identifier (payment account linked to your Stripe Connect account)

    4.2 What is Reported

    If you exceed the reporting thresholds (more than 30 sales or more than €2,000 in total consideration in a calendar year), we are required to report:

    • Your identification information and TIN
    • Total consideration paid or credited per quarter
    • Number of sales per quarter
    • Any fees, commissions, or taxes withheld by the platform

    This information is reported to the Slovak tax authority, which may share it with tax authorities in your country of residence under the EU automatic exchange of information framework.

    4.3 Your Obligations

    You are solely responsible for your own tax obligations, including income tax, VAT (if applicable), and any other taxes on your sales. The platform does not provide tax advice.

    4.4 Sale Documents Issued in Your Name (Invoicing Mandate)

    By accepting this Agreement, you authorize the platform to issue sale documents to buyers in your name and on your behalf for each completed order, as permitted by Article 220 of Council Directive 2006/112/EC and §72 of the Slovak VAT Act (invoicing by a third party in the name and on the account of the supplier). The type of document depends on your declared seller status:

    • Private individuals: a proof-of-sale document (not a VAT invoice), reflecting the occasional sale of used goods from personal property.
    • Professional sellers not registered for VAT: an invoice without VAT, marked "Seller is not a VAT payer".
    • VAT-registered sellers: a VAT invoice under the applicable scheme per item — standard rate, reverse charge (cross-border B2B), or the second-hand margin scheme (§66 of the Slovak VAT Act) where its conditions are met. Margin-scheme items do not show VAT separately, as required by law.

    Documents are generated from the tax-status information in your shop profile and listings (seller type, VAT registration and country, margin-scheme eligibility, per-item acquisition costs). You warrant that this information is accurate and will keep it up to date; you remain solely responsible for the correctness of the tax treatment applied to your listings — in particular that the margin scheme is used only for eligible used goods acquired without deductible VAT and that you keep the required acquisition records. Each shop has its own document numbering series. If you believe a generated document is incorrect, contact support without undue delay and we will issue a correction.

    5. Listings and Prohibited Items

    5.1 Permitted Items

    You may list the following categories of items:

    • Card listings: Physical trading cards from your Citadel TCG inventory
    • Sealed product listings: Factory-sealed trading card products from your sealed inventory
    • Custom listings: Other trading card-related items (subject to admin approval before becoming visible)

    5.2 Prohibited Items

    You may not list:

    • Counterfeit or replica cards
    • Stolen goods
    • Items that infringe intellectual property rights
    • Digital-only items or codes (unless specifically permitted)
    • Items that violate any applicable law
    • Items unrelated to trading card games
    • Alcohol, tobacco, weapons, drugs, or other regulated goods

    5.3 Listing Accuracy

    You must ensure that all listings accurately describe the item, including condition, edition, language, and any defects. Misleading or deceptive listings may result in listing removal and account suspension.

    6. Pricing and Commission

    6.1 Pricing

    You set the price for your listings. If you are a professional seller, prices displayed to consumers must include all applicable taxes (VAT). When advertising price reductions, you must display the lowest price you offered in the 30 days preceding the reduction, in accordance with the Omnibus Directive.

    6.2 Platform Commission and Payment-Processing Fee

    Each sale is subject to: (a) our platform commission of 1.5% of the order amount including shipping, unless a different rate was agreed with you in writing before the sale; and (b) a payment-processing fee equal to your order's share of the fee Stripe actually charges for the buyer's payment.

    Stripe's fee depends on the payment method. On 15 October 2026 it is 1.5% + €0.25 for a standard EEA card, 2.8% + €0.25 for a premium EEA card, 2.5% + €0.25 for a UK card and 3.15% + €0.25 for other international cards (plus 2% where currency conversion is required), and 0.5% (at most €5.00) for a SEPA bank transfer; the current list is at stripe.com/sk/pricing. Changes in Stripe's published fees are passed on to you without mark-up and notified under section 17.

    Where one payment covers orders from several shops, the fee is split in proportion to each order's amount. Example: a buyer pays €60.00 by standard EEA card for €40.00 from shop A and €20.00 from shop B; Stripe's fee is 1.5% + €0.25 = €1.15, of which shop A bears €0.77 and shop B €0.38.

    Both amounts are deducted under this fixed formula before the remainder is transferred to your Stripe account; we cannot change the formula for an individual order. Every order shows both amounts, and the monthly invoice (6.4) lists them. The payment-processing fee under (b) and the costs under 6.4 are part of the price of our platform service, calculated from the fees Stripe charges us without mark-up. All amounts in sections 6.2 and 6.4, including the examples, include VAT where VAT is due on our service; we account for that VAT out of them and charge you nothing on top.

    Fees on both sides. From 3 November 2026, or from your acceptance of this version if earlier, buyers without an active Citadel Premium or Lite subscription pay us a buyer service fee of 1.5% of the item prices and shipping of each order (Buyer Terms, section 5), in addition to the commission and payment-processing fee under this section. The buyer service fee is our own charge to the buyer: it is not part of your sale price, it is not paid out to you and it does not reduce your proceeds. You must not charge buyers any amount for it or state that your prices include it.

    Buyer service fee in seller-caused refunds. If an order is refunded in full or in part for one of the following reasons, you bear all fees for that order — the commission and the payment-processing fee are not returned to you — and the platform fee for that order also includes an amount equal to the buyer service fee we refund to the buyer: (a) you cancel the order, unless the buyer asked you to or has withdrawn from the purchase; (b) you do not ship the order within 7 days of payment; (c) the order does not arrive and you cannot provide tracking showing delivery, including a card dispute lost because the order was not received; (d) we uphold the buyer's report that the item is significantly not as described, damaged or counterfeit, including a card dispute lost because the item was not as described. The amount is shown as a separate line with the order number on your monthly invoice (6.4(d)). Example: items and shipping €12.00, buyer service fee €0.18; if you do not ship within 7 days, the buyer receives €12.18 back and your platform fee for that order increases by €0.18. No amount for the buyer service fee is charged where the refund results from the buyer's own cancellation or withdrawal. We tell you the amount at least 7 days before we collect it (6.4(c)); in case (d), if you object within that time, we collect it only after your objection has been decided, with reasons, within 10 business days.

    If the price is reduced and the buyer keeps the item, the corresponding part of the price is taken from your proceeds and no fees are returned. When the buyer cancels an order or withdraws from the purchase of their own choice, the commission is returned to you and the payment-processing fee is not.

    6.3 Currency

    You select your shop currency (EUR or USD) during shop setup. Buyers may see converted prices in their local currency at applicable exchange rates.

    6.4 Payout Costs, Refund Costs and Monthly Invoice

    (a) Payout costs. For each payout from your Stripe account to your bank account (section 7) you bear the costs Stripe charges us for it: a payout fee of 0.25% of the amount paid out + €0.10, a funds-routing fee of 0.25% of the amount paid out, and €2.00 for each calendar month in which at least one payout is sent to you. We collect these costs from your Stripe account immediately before the payout by an account debit under (c); you also bear Stripe's account-debit fee of 1.4% of the amount collected.

    Each cost is calculated on its own and rounded to the nearest cent (half up); where rounding leaves a cent or two, we bear it, so we never collect more than Stripe charges. Example: with €100.00 available and no earlier payout that month, the costs are €2.62 (€2.00 monthly fee, €0.34 payout fee, €0.24 funds routing, €0.04 account-debit fee) and €97.38 arrives in your bank account; a further payout of €100.00 in the same month costs €0.61 and €99.39 arrives. With €10.00 available, €7.83 arrives on the first payout of a month and €9.86 on a later one. Before every payout you see the full calculation. If the costs would exceed the amount available, no payout is made and the amount stays in your Stripe account until it covers them.

    (b) Refund costs. A refund or dispute is caused by you if you cancel a paid order for a reason other than the buyer's request or withdrawal, if you do not ship a paid order within 7 days of payment, if you do not provide tracking evidence within 14 days after the buyer reports that the order did not arrive, or if a card dispute, or a buyer's complaint decided by our support, goes against you because the item was not delivered or did not match its listing. What you bear for such a refund under 6.2 — the refunded price, the fees that are not returned to you and the buyer service fee you reimburse — is first taken back by reversing the transfer for that order (section 7); what the reversal cannot cover is a refund cost, collected under (c). For a lost card dispute caused by you, you also bear Stripe's dispute fee of €20.00 where the card issuer's stated reason was non-delivery or that the item did not match its listing; we bear the further €20.00 Stripe charges when a dispute is countered. When the buyer cancels or withdraws of their own choice, the payment-processing fee for that order is not returned to you (6.2): what the transfer reversal does not cover of it is collected with your next payout like the costs in (a), without a notice period or objection; you see it in your shop. We bear the refund costs in all other cases.

    (c) Collection. You authorise us to instruct Stripe to collect from your Stripe account balance only amounts that (i) are due under this section 6.4 or remain unpaid after a transfer reversal under section 7, (ii) are quantified and shown to you in your shop before collection, and (iii) are in your Stripe account's default currency. Payout costs under (a), and the payment-processing fee of a refund the buyer chose under (b), are collected with the payout. Before collecting any other amount under (b), or an amount that remains unpaid after a transfer reversal, we show it in your shop and notify you by e-mail with the order, the reason and the amount at least 7 days before collection. If within those 7 days you object that the refund or dispute was not caused by you, we do not collect the amount until we have decided on your objection; we decide within 10 business days and give reasons by e-mail, and you may then use the complaint procedure (section 14), mediation (section 15) or the courts. If you object later, any amount collected without basis is refunded within 10 business days. We never collect more than the amount due. Your right to set off your own claims against us is not affected.

    (d) Monthly invoice. Each month we issue, within 15 days after its end, one summary invoice listing (A) our commission per order and (B) the payment-processing, payout and refund costs per order and per payout and the buyer service fee you reimburse for a refund caused by you, each with its date of supply.

    7. Payments and Payouts

    All payments are processed by Stripe (Stripe Payments Europe, Limited and Stripe Technology Europe, Limited). When a buyer pays:

    • The buyer pays by card or SEPA bank transfer to Stripe. The payment is recorded in our Stripe platform balance and, immediately and automatically when it succeeds, Stripe transfers the amount for your order — the order price less the amounts in 6.2 — to your Stripe account. We cannot change this amount or delay this transfer. We act in your name and on your behalf only to give Stripe the instructions listed in sections 6.4, 7 and 9 and to operate the withdrawal function under section 9; Stripe holds the money, it never reaches our own bank account and we may not use it for our own purposes.
    • Every sale through the Platform is concluded directly between you and the buyer on the sale conditions in sections 4 and 5 of the Buyer Terms, which form part of each offer you make on the Platform. In particular, the buyer must pay in full within 7 days of placing the order (within one hour if the buyer's purchases are limited to immediate card payment under the Buyer Terms); otherwise the purchase contract ends automatically, neither you nor the buyer owes anything further and the items return to your shop. If a contract has not ended in this way, you withdraw from it when the payment period expires, and our expiry e-mail to the buyer is your notice of withdrawal. We transmit your offers, the buyers' orders and these notices on your behalf; we do not negotiate or conclude contracts in your name.
    • Money for an order becomes available for payout 24 hours after the buyer confirms receipt or, if the order was shipped, 30 days after the order, whichever comes first. While a dispute or a withdrawal by the buyer is open for an order, only the amount of that order stays held, and never beyond the 80 days in the next point; a withdrawal for which the buyer does not mark the goods as sent back within 21 days no longer holds it.
    • You pay out available money to your bank account on request in your shop, or automatically by a rule you set (an amount you choose, or every set number of weeks or months). A payout can be requested once at least €10 is available; the costs in 6.4 are deducted from that amount (see the example in 6.4). Any amount that has not been paid out within 80 days of its transfer to your Stripe account is paid out automatically, also below €10 and also while a dispute or withdrawal is open, unless it is held under section 13.4 because of a legal obligation or an order of a court or authority, because Stripe requires funds held on a manual payout schedule to be paid out within 90 days. A refund or a lost dispute after that is taken back under the sixth point.
    • With your consent, your Stripe account's payout schedule is set to manual and the Stripe Express Dashboard functions for changing the payout schedule and paying out are disabled; payouts are made only through the Platform under the rules in this section.
    • If a buyer is refunded or a card dispute is lost, Stripe refunds the buyer and we reverse the transfer for that order from your Stripe account. If your available balance is not sufficient, the missing amount is taken back as soon as your balance allows it or collected under 6.4(c), and you remain liable for it.
    • While your shop is suspended or your account is blocked, payouts may be held only on the grounds, to the extent and for the time set out in section 13.4.

    8. Shipping and Fulfillment

    • You are responsible for shipping items to buyers in a timely manner
    • You must set up shipping profiles with clear rates and delivery timeframes
    • Shipping costs and estimated delivery times are displayed to buyers at checkout and included on invoices
    • You must update order status (shipped, tracking information) promptly
    • You bear the risk of loss or damage during shipping unless otherwise agreed with the buyer

    8a. Cross-border shipments

    8a.1 When an order crosses a customs border, the order shows it. You must complete the customs declaration (CN22/CN23 or your carrier's electronic customs data) truthfully: the type "Sale of goods" (never "Gift" or "Sample"), the actual price paid in the order, a description such as "Trading cards" (tariff code 9504 40), and one parcel per order. Splitting orders or undervaluing parcels is prohibited.

    8a.2 Only when the order states "UK VAT collected by Citadel": enter Citadel's UK VAT number (GB529779234) in your carrier's electronic customs data and, where the form has the field, as the "Importer's reference" on the CN23; attach the customs document from the order, and do not charge UK VAT yourself. Keep proof of dispatch for as long as your tax law requires. Never use Citadel's VAT number for any other parcel. Private sellers never use it.

    8a.3 Keep the shipping origin in your shipping profiles accurate. Buyers see customs notices based on it. A misstated origin is a breach of these terms (section 13).

    8a.4 When a buyer returns goods across a border, ask them to mark the parcel "Returned goods" so you are not charged import charges on it.

    8a.5 Until Citadel supports the necessary tax schemes, professional sellers established or shipping outside the EU cannot sell to buyers in the EU, and professional sellers established outside the UK cannot sell to buyers in Great Britain. Citadel will notify you when this changes.

    9. Returns and Consumer Rights

    9.1 Professional Sellers

    If you are a professional seller, you are subject to EU consumer protection laws, including:

    • Right of withdrawal: Consumers may withdraw within 14 days of receipt without giving a reason, using the withdrawal button in the order or any other clear statement. If the order has not been shipped yet, the withdrawal cancels it and the buyer is refunded at once. Otherwise you must refund the price including the standard delivery cost within 14 days of the withdrawal, using "Refund order" in the order; you may wait until you receive the item back or the buyer shows that it was sent. If the refund is still missing 14 days after the buyer marked the item as sent back, our support takes over the case.
    • Liability for defects (legal guarantee of conformity): You are liable for any lack of conformity that becomes apparent within the period that applies under the law governing the sale, usually the law of the buyer's country: 2 years in Slovakia and most EU countries, longer or without a fixed limit in some (for example Spain, Portugal, Sweden, Ireland and the Netherlands); see Liability periods by country. Shorter liability period for used items. Singles (cards and graded cards) are treated as used unless you mark the listing as new; a custom item only when you mark it used; sealed products never. Mark a single as new when it has never been played or used. For a used item we offer the buyer at checkout the period shown for the buyer's delivery country in that table (currently 1 year for Slovakia, the Czech Republic, Germany, Belgium and Italy, and 18 months for Portugal), with a separate notice before ordering and a separate box the buyer must tick. The shorter period applies only to a consumer who ticks the box and only if the agreement is stored in the order; for all other countries and buyers, and whenever the agreement is not stored, the full statutory period applies. In Austria and Spain we do not offer a shorter liability period for used goods; the full statutory period applies. A defect that appears during the presumption period that applies in the buyer's country is presumed to have existed at delivery unless you prove otherwise or this is incompatible with the nature of the item or of the defect. Under Slovak law, after the first repair the period is extended once by 12 months, and wear consistent with the item's previous use and its condition stated in the listing is not a defect. Defective goods must be repaired or replaced, or the price reduced or refunded. We provide the checkout function and the table as a tool and update them when we learn of changes in the law; you remain responsible for your obligations as a seller.
    • Photos and serial numbers of the item sold. A card or other item (except sealed products) priced at 50 € or more needs two photos of the actual item, the front and the back; until you add them the listing stays paused. A graded card needs its grading company and slab serial (cert) number. They are stored with each order as evidence of the item sold, and the item you ship must be the one shown.
    • Return shipping costs: You determine and clearly disclose who bears the cost of return shipping in your shop policies. This must be visible to buyers before purchase.

    Withdrawal function. The Platform provides, on your behalf and in your name, the withdrawal function required by Article 11a of Directive 2011/83/EU and the national laws implementing it (in Slovakia § 20a of Act No. 108/2024 Coll.). You instruct and authorise us to receive withdrawal notices submitted through it and to send buyers the acknowledgement of receipt in your name. A withdrawal submitted through the function is received by you at the time of submission. You must not offer buyers a withdrawal process that conflicts with it. Because the law requires this function, this paragraph applies from its publication (Article 3(4)(a) of Regulation (EU) 2019/1150).

    9.1a Order evidence – licence and retention

    • (a) When an order for an item that requires photos or a slab serial number is paid, CITADEL copies the photos of that item (front and back) and the grading company and serial number you provided ("Order Evidence") and stores them with the order.
    • (b) You grant Castellum - Forge s.r.o. a non-exclusive, royalty-free, worldwide licence, irrevocable for the period in (d), which it may sub-license only to the persons listed below, to reproduce, store and make Order Evidence available: (i) to the buyer of that order, to you and to our staff handling the order; (ii) to payment service providers (including Stripe), out-of-court dispute resolution bodies, courts, public authorities and our professional advisers, where needed to handle a complaint, return, chargeback, dispute, fraud check or legal claim related to that order, or to comply with the law. We will not use Order Evidence for advertising.
    • (c) This licence continues after you edit or delete the listing or close your account, because Order Evidence records the item that was actually sold. You confirm that you have the right to grant this licence for your photos. You do not grant rights in the card artwork itself.
    • (d) We keep Order Evidence for 6 years after delivery of the order or, if a complaint, dispute, chargeback or proceeding about the order is started within that time, until it has been finally resolved, whichever is later. After that we delete it.
    • (e) Order Evidence is stored in non-public storage and is accessible only through time-limited links issued to the persons in (b). Please photograph only the item and do not show people, addresses or other personal information. If personal data is visible, we process it as described in our Privacy Notice for the purposes in (b).

    9.2 Private Sellers

    If you are a private individual seller, the 14-day right of withdrawal and legal guarantee do not apply. However, you must still accurately describe items and not engage in deceptive practices.

    9.3 Sealed Products

    Sealed trading card products (booster packs, boxes, etc.) where the seal has been broken after delivery may be exempt from the right of withdrawal under Article 16(e) of the Consumer Rights Directive, as goods that are not suitable for return due to health protection or hygiene reasons and were unsealed after delivery. This exemption applies only to factory-sealed products with an intact seal.

    9.4 Parcels refused because of import charges

    If a buyer refuses a parcel because of import charges, refund them according to Buyer Terms section 6a.5 once the parcel is back with you. If it does not come back, the dispute procedure decides.

    10. Content and Intellectual Property

    • You may only use images you own or have the right to use in your listings
    • Card images from your Citadel TCG inventory may be used in associated listings
    • You must respect the intellectual property rights of card game publishers
    • We will act on valid IP infringement notices by removing infringing listings and notifying you with a statement of reasons
    • If you believe a listing was wrongly removed, you may submit a counter-notice through our complaint-handling system

    11. Ranking and Visibility

    In accordance with the Platform-to-Business Regulation (EU) 2019/1150, the following parameters determine how listings are ranked in search results and marketplace browsing:

    • Relevance: How closely the listing matches the buyer's search query (highest weight)
    • Recency: More recently listed or updated items may appear higher
    • Seller rating: Sellers with higher average ratings may receive a ranking boost
    • Completion: Listings with complete information (images, description, condition) rank higher
    • Price: When buyers sort by price, this becomes the primary parameter

    Paid promotion: Sellers may use the advertising system to promote listings. Promoted listings are clearly labeled as "Sponsored" and appear in designated ad placements. Paid promotion does not affect organic search ranking.

    Public visibility: The marketplace is publicly browsable. By opening a shop you acknowledge and agree that your shop profile (name, URL, bio, logo, banner, location, seller type, rating) and your active listings (item, price, condition, language, quantity, images) are visible to anyone on the internet without authentication and may be indexed by search engines. Professional sellers' support e-mail address is also displayed publicly. The categories of publicly visible data are described in section 6.3 of the Privacy Policy.

    12. Data Access and Portability

    You have access to the following data through your shop dashboard:

    • All your listing data (items, prices, images, status)
    • Order history and details (buyer display name, shipping address, amounts)
    • Sales analytics (total sales, revenue, average rating)
    • Reviews and ratings received
    • Shipping profile configurations

    You may request a full export of your seller data by contacting us at info@castellum-forge.net. Upon termination of your shop, you may request your data for a period of 30 days after closure.

    13. Account Restriction, Suspension, and Termination

    13.1 Restrictions and Suspensions

    We may restrict or suspend your selling privileges if you violate this Agreement, receive repeated complaints, or engage in conduct that harms the marketplace. Before restricting or suspending your account, we will:

    • Provide a statement of reasons on a durable medium (email)
    • Give you an opportunity to clarify the facts and remedy the issue

    13.2 Termination

    We may terminate your seller account with at least 30 days' written notice, delivered by email, with a clear statement of reasons. The 30-day notice period may be waived in cases of:

    • Repeated violations of this Agreement
    • Legal or regulatory obligations requiring immediate termination
    • Demonstrable risk that the seller is engaged in illegal activity

    13.3 Consequences of Termination

    Upon termination, all active listings are deactivated. Outstanding orders must still be fulfilled. Money in your Stripe account is paid out under section 7 as soon as it becomes available, after deduction of amounts due under 6.4. Amounts may be held after termination only on the grounds in section 13.4 and to the extent set out there; nothing is held beyond 80 days after it became available except because of a legal obligation or an order of a court or authority. Section 12 describes the data you can still access after termination.

    13.4 Holding payouts during suspension or blocking

    While your shop is suspended or your account is blocked under this section 13, we may hold payouts only on one or more of these grounds: (a) orders that are not yet delivered or confirmed; (b) open buyer disputes, chargebacks or refund requests; (c) a reasonable, documented suspicion of fraud or of counterfeit items; (d) a legal or regulatory obligation or an order of a court or authority; (e) amounts you owe under 6.4. We hold only the amount reasonably needed to cover the risk concerned, not your whole balance. A hold stays in place until we decide on it again or the suspension or block ends.

    We will tell you by e-mail, at the latest when the hold starts, which ground applies, the facts, how long the hold is expected to last and how you can contest it (section 14) and use mediation (section 15). You may request a payout at any time; our support decides within 5 business days and gives reasons by e-mail if it refuses, and if it does not decide in time the payout is made. Amounts not needed for these purposes are released. All held amounts that are not subject to a legal obligation or an order of an authority are paid out no later than 80 days after they became available; open disputes are then settled under sections 6.4 and 7.

    14. Complaint Handling

    We provide an internal complaint-handling system for sellers. If you have a complaint about our decisions regarding your shop, listings, or account, you may:

    • Submit a complaint via email to info@castellum-forge.net
    • We will acknowledge receipt and investigate your complaint
    • We will communicate the outcome with reasons in a timely manner
    • The process is free of charge

    15. Mediation

    In accordance with Article 12 of the P2B Regulation, if a dispute cannot be resolved through our internal complaint-handling system, you may seek resolution through the following mediators:

    • Centre for Effective Dispute Resolution (CEDR) — www.cedr.com
    • Slovak Mediation Centre (Centrum pre mediáciu) — operated under the Slovak Ministry of Justice

    We will engage in good faith in any mediation attempt.

    If you are a consumer (a private seller), you may also submit a dispute with us to an alternative dispute resolution entity: Slovenská obchodná inšpekcia (Slovak Trade Inspection), Ústredný inšpektorát, Odbor pre medzinárodné vzťahy a alternatívne riešenie spotrebiteľských sporov, Bajkalská 21/A, P.O. Box 29, 827 99 Bratislava 27, Slovak Republic, ars@soi.sk, or any other authorised entity listed by the Ministry of Economy of the Slovak Republic.

    16. Liability

    You are solely responsible for the items you sell, their description, quality, safety, and legal compliance. The Platform acts as an intermediary and is not a party to the sale. You agree to indemnify Castellum - Forge s.r.o. against any claims arising from your marketplace activities.

    17. Changes to This Agreement

    We may change this Seller Agreement only for these reasons: (a) changes in applicable law or regulation, or decisions of courts or authorities; (b) changes in Stripe's terms or published fees, which are passed on without mark-up; (c) the introduction of new Platform features or the change or withdrawal of existing features, where the change does not reduce the core service you receive; (d) security reasons and the prevention of fraud or abuse; (e) a change of our commission, at most once per calendar year.

    We will notify you of any change by e-mail at least 15 days before it takes effect (30 days for a change of our commission, and longer if the change requires technical or commercial adjustments on your part), stating what changes and why. You may accept a change earlier by clicking "Accept & Continue" in your shop. If you do not agree, you may terminate your seller account free of charge before the change takes effect; money in your Stripe account is then paid out under sections 7 and 13.3. Changes never apply retroactively. A change may take effect sooner only where a legal or regulatory obligation requires it, or where we must address an unforeseen and imminent danger to the Platform, buyers or sellers from fraud, malware, spam, data breaches or other cybersecurity risks; we will still inform you without undue delay.

    18. Governing Law

    This Seller Agreement is governed by the laws of the Slovak Republic. Disputes shall be submitted to the competent courts in Nitra, Slovak Republic, without prejudice to your right to seek mediation as described in Section 15.

    This Agreement is published in English and in translations; all language versions have the same content, and the version and language you accepted are stored. If language versions differ: if you act as a business, the English version prevails; if you are a consumer, the version in the language in which you accepted applies, and in case of doubt the interpretation more favourable to you prevails, without affecting mandatory rules of the law of your country on the language of consumer contracts. The translations into Chinese, Hindi, Arabic, Bengali, Russian and Urdu are informative; for them the English version is binding.
