Privacy Policy
Last updated: October 2026
Rincon TCG ("we," "our," or "us") is committed to protecting your privacy. This policy explains how we collect, use, and share information when you use our app and website at rincontcg.app.
1. Information We Collect
We collect information you provide directly to us, such as your email address and username when you create an account. The username you choose is checked by Anthropic's Claude API to keep the community family-friendly. We also collect usage data (pages visited, features used) and device information (platform, browser type) to improve the app. If you use card scanning, photos of your cards are uploaded to our servers and processed by Anthropic's Claude API — these images are stored in Supabase Storage and are not shared with third parties for advertising purposes.
2. Location Information
If you use the store map or report a stock sighting, we collect your device's precise location (with your permission) and/or the ZIP code you enter to show nearby stores and power restock alerts in your area. Location permission is optional — you can deny it and still browse stores by ZIP code. Sighting reports you submit include the store's location, not your own, and may be shown to other users. When you look for events near you, the ZIP code you enter or your device's location (with your permission) is used for that search only and is not stored. Events you post (their name, place, dates and description) are shown to everyone once we approve them; we keep a record of which account posted each one, which is not shown.
3. Profile Pages and Friends
If you choose a username, you get a profile page at rincontcg.app/u/your-username. Anyone with the link can see your username, your profile picture if you have one, the month you joined, and any binders you make public. You choose who sees the rest under "Who sees what" on the Friends page: your card count, collection value, full collection, Want List and trade matches can each be seen by only you, your friends, or everyone (for trade matches, any signed-in member). Until you change them, your card count is shown to everyone, your Want List and trade matches to your friends, and your full collection and its value only to you. Trade matches show another member which cards on your Want List or binder wishlists they have, and which of your cards they need, with how many copies you have. When you send a friend request, the other person sees your username.
4. How We Use Your Information
We use the information we collect to provide, maintain, and improve Rincon TCG, to process transactions via Stripe, to send restock alerts and notifications you have subscribed to, and to respond to your support requests. We do not sell your personal information.
5. Payment Information
All payment processing is handled by Stripe. We do not store your full credit card number, CVV, or expiry date. Stripe processes and stores payment details in accordance with PCI-DSS standards. You can review Stripe's privacy policy at stripe.com/privacy.
6. Push Notifications
If you enable push notifications, we store your device token or Web Push subscription to deliver restock alerts. You can disable notifications at any time in your account settings or device settings.
7. Data Retention & Account Deletion
We retain your account data for as long as your account is active. You can permanently delete your account and associated data at any time from the Account page (Account → Delete Account), or by contacting support@rincontcg.app. Card scan photos are kept to measure and improve scanning accuracy, then deleted automatically: photos of scans the app identified with confidence, and short clips of a card being tilted that you choose to record, after 30 days; photos of scans it was unsure about, that you corrected or that you reported as wrong, after 90 days.
8. Third-Party Services
Rincon TCG uses the following third-party services: Vercel (website hosting), Supabase (database and authentication), Stripe (payments), Anthropic Claude (card scanning, and checking that usernames are family-friendly), Voyage AI (card image matching), Mapbox (store maps), Firebase Cloud Messaging (push notifications), Google Workspace and Resend (email delivery), and Sentry (error reports). Each service operates under its own privacy policy. When something in the app breaks, an error report goes to Sentry so we can fix it: what went wrong, the page it happened on, and your browser and device type. Error reports do not include your IP address or cookies, and we do not record your screen.
9. Children's Privacy
Rincon TCG is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately.
10. Changes to This Policy
We may update this privacy policy from time to time. We will notify you of significant changes by posting the new policy on this page and, where appropriate, by email.
