5.2 Billing and Auto-Renewal

Subscriptions are billed in advance on a recurring basis (weekly, monthly, or annually) depending on your selected plan. Your subscription automatically renews at the end of each billing cycle unless you cancel before the renewal date.

5.3 Payment Methods and In-App Purchases

Payments on the web are processed by Stripe, Inc. Subscriptions purchased in the mobile app are in-app purchases processed through the Apple App Store (iOS) or Google Play Store (Android) via RevenueCat, Inc. By providing payment information, you authorize the applicable payment processor (Stripe, Apple, or Google) to charge your chosen payment method on the recurring billing schedule described in Section 5.2.

5.4 Cancellation

You may cancel your subscription at any time through the Stripe customer portal (web) or your device's subscription management settings (iOS Settings > Apple ID > Subscriptions, or Google Play > Subscriptions). Cancellation takes effect at the end of the current billing period; you will retain access to paid features until that date, after which the subscription will not renew. There is no partial refund for the remaining period.

5.5 Restore Purchases (iOS and Android)

If you reinstall the mobile app, switch devices, or sign in with a different account on the same Apple ID or Google account, you may restore a previously purchased subscription using the "Restore Purchases" option in the app paywall. Restoring purchases does not result in a new charge — the original subscription receipt issued by Apple or Google is re-validated and entitlements are re-applied. Restore Purchases works only with the same Apple ID or Google account that originally made the purchase.

5.6 Right of Withdrawal (EU/UK consumers)

If you are a consumer in the European Union or the United Kingdom and you purchased your subscription directly from us through the web (Stripe), you have the right to withdraw from the subscription contract within 14 days of the initial purchase without giving any reason. To exercise this right, contact us at info@castellum-forge.net or use the withdrawal form. If you have already accessed premium features during the withdrawal period, you acknowledge that you expressly consented to the commencement of performance and that you may be required to pay for the service already provided.

For subscriptions purchased through the Apple App Store or Google Play Store, refund eligibility is governed by the policies of those respective platforms (Apple Media Services Terms, Google Play refund policy), not by this Section. Refund requests for App Store purchases must be submitted directly to Apple at reportaproblem.apple.com, and Google Play purchases at play.google.com/store/account.

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." To the maximum extent permitted by applicable law, we disclaim all warranties, whether express, implied, statutory, or otherwise, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement.

15. Account Suspension and Termination

15.1 By You

You may delete your account at any time through your account settings (Account > Settings > Delete Account). Account deletion initiates a 30-day recovery window during which you may restore your account by signing in again. After the recovery window expires, your personal profile data, collections, wishlists, posts, comments, chat messages, friend connections, and avatar are permanently deleted.

Legal retention exception. Certain data must be retained beyond account deletion to comply with our legal obligations under GDPR Article 17(3)(b) (compliance with a legal obligation) and Slovak Act No. 222/2004 Coll. on VAT and Act No. 431/2002 Coll. on Accounting. Specifically:

• Invoices and transaction records — retained for 10 years for tax and accounting compliance;
• Marketplace orders and dispute records — retained for 10 years for consumer protection and dispute resolution;
• Content moderation records (reports, takedowns, appeals) — retained for up to 6 months after resolution per DSA Article 17(5);
• Anonymized public posts already shared in feeds may persist for up to 30 days after deletion to allow for rollback in case of mass abuse, after which they are anonymized or removed;
• Backups — full database backups are retained for 30 days on a rolling basis, after which they are overwritten.

For full details of retention periods by data category, see our Privacy Policy Section 9. Cancellation of an active subscription (Section 5.4) is separate from account deletion and does not by itself trigger data deletion.

15.2 By Us

We may suspend or terminate your account if you materially breach these Terms. Before taking such action, we will (except in urgent cases involving illegal activity or risk of harm):

• Provide you with a clear statement of reasons
• Give you an opportunity to respond and remedy the breach

16. Governing Law and Jurisdiction

These Terms are governed by the laws of the Slovak Republic. Any dispute arising from these Terms shall be submitted to the competent courts in Nitra, Slovak Republic.

For consumers: If you are a consumer residing in the EU, this choice of law does not deprive you of the protection of mandatory provisions of the law of your country of habitual residence. You may also bring proceedings in the courts of your country of habitual residence.

17. Dispute Resolution

Before initiating any formal proceedings, we encourage you to contact us to resolve disputes informally. If informal resolution is not possible:

• Internal complaint: Use our complaint-handling system accessible through the Service or by emailing info@castellum-forge.net.

• Notify you via email or in-app notification at least 15 days before the changes take effect

Your continued use of the Service after the effective date constitutes acceptance of the updated Terms.

• Severability: If any provision is found to be unenforceable, the remaining provisions remain in full force and effect.
