Privacy Policy

Thoughtseize ("the App") respects your privacy. This policy explains what data the App collects, how it is used, and your choices.

What we don't collect

• We don't track you. No advertising IDs, no analytics, no behavioural tracking. The App does not use Apple's App Tracking Transparency framework because it has nothing to track.
• We don't sell, share, or rent your data to advertisers, brokers, or any third party for marketing purposes.
• We don't read or store the images you scan. Card recognition runs entirely on-device using Apple's Vision framework. Camera frames are processed locally and immediately discarded.

What's stored on your device

By default, all of your data lives on your iPhone and never leaves it:

• Cards in your vault (name, set, quantity, price snapshots)
• Decks you build, scan history, wishlist, app preferences

This data is stored in Apple's standard local data store (SwiftData). Removing the App removes all of this data.

Optional sync between your iPhones

If you sign in via Settings → Sign In, the App stores a copy of your vault, decks, scan history, and price snapshots on a Supabase server so you can use the same data across multiple iPhones. To sign in we collect:

• Your email address (used as your account identifier)
• A Supabase authentication token (managed by Supabase, not stored by us in plain text)

Sync data is encrypted in transit via TLS and protected by row-level security on the server so only you can read your own data. You can sign out at any time from Settings, which immediately stops syncing and removes the auth token from your device.

To delete your account and all server-side data, email stephenamazon96@gmail.com from the address associated with your account. We'll process the request within 7 days.

Third-party APIs we contact

When you look up cards, build decks, or refresh prices, the App fetches public card data from these services. None of these requests include any personal data — only card names, set codes, or Scryfall IDs:

• Scryfall — card metadata, pricing, images
• EDHREC — Commander deck recommendations
• Commander Spellbook — combo detection
• MTGJSON — retailer buylist prices

Each service has its own privacy practices, which we don't control.

Camera and notifications

• Camera is requested only when you tap the Seize tab and is used solely for on-device card scanning. We never upload or transmit camera frames.
• Local notifications (used for price alerts) are scheduled on your device by iOS. We don't see them and don't use any push notification servers.

Children

Thoughtseize is rated 4+. We don't knowingly collect any data from children under 13. If you believe a child has signed up for sync, email us and we'll delete the account.

Your rights

• Access — your data is visible in the App at all times.
• Export — Settings → Collection IO → Export lets you download your vault as CSV.
• Delete — sign out from Settings to stop sync; email us to permanently delete server-side data.

Changes to this policy

If this policy changes meaningfully, we'll update the "Last updated" date and note the change here. Continued use of the App after a change means you accept the revised policy.
