Binder ("we", "us", "our") is a trading card collection tracker and AI grading app. This policy explains what information we collect, how we use it, and the choices you have.
| Data | Why we collect it |
|---|---|
| Email address | Create and sign in to your account |
| Photos of your cards | AI condition grading and adding cards to your collection |
| Collection & grading data | Track your cards, values, and AI grade history; improve grading accuracy in aggregate |
| User ID | Identify your account and secure your data |
| Purchase history | Verify your subscription tier and unlock features |
| App activity (streaks, points) | Power leaderboards and understand feature usage |
We do not store your precise location. The optional store-locator map uses your device's location only on your device to center the map, and it is never sent to us. We do not use advertising SDKs and we do not track you across other companies' apps or websites.
We use the following service providers to operate Binder. Each processes data only to provide their service to us and may not use your data for their own advertising.
| Provider | Purpose |
|---|---|
| Supabase | Database, authentication, and file storage |
| Anthropic | AI analysis of card photos for condition grading |
| RevenueCat | Subscription and purchase management |
| Apple App Store | Payment processing (we never see your card details) |
We do not sell your personal information, and we do not share it with data brokers.
We keep your data while your account is active. If you delete your account, your personal data is removed; aggregated, de-identified statistics that no longer identify you may be retained to keep the product accurate for other users.
Binder is not directed to children under 13, and we do not knowingly collect personal information from children under 13.
We use industry-standard measures (encryption in transit, access controls) to protect your data, but no method of transmission or storage is 100% secure.
We may update this policy as Binder evolves and will update the date above when we do.
