Flip Rock — Privacy Policy
Effective date: 2026-10-01
Flip Rock ("we", "us") is a quiet daily game. This policy explains what we collect, why, and your choices. We keep data collection to the minimum needed to sign you in and save your progress. We do not sell your data, show ads, or use third-party tracking.
What we collect
- Sign in with Apple — Apple gives us an anonymous Apple user ID, plus your email address or a private relay address if you choose to share one. It's used only to sign you in; there are no passwords.
- Phone number — held only for accounts created before Flip Rock switched to Sign in with Apple. We no longer collect phone numbers.
- Gameplay data — your collectors, which specimens you've discovered and the dates you've flipped, tied to your account so your field guide is saved.
- Purchase records — if you buy a pack, a record of that purchase (see Purchases below).
We do not collect your location, contacts, photos, microphone, advertising identifiers, or analytics/behavioral data.
How we use it
- To sign you in (Sign in with Apple, or the phone number on older accounts).
- To save and sync your collection and once-per-day flip across your devices.
- To unlock the packs you've bought and restore them on your devices.
Purchases
Flip Rock sells packs: optional, one-time purchases of named specimen packs. Apple processes every payment through the App Store, so we never see your payment details (your card, billing address or Apple ID password).
When you buy or restore a pack, the app sends Apple's signed record of the transaction to our server, which checks it with Apple and unlocks the pack for your account. We keep the product you bought, the transaction identifiers, the purchase date, whether it's your own purchase or a Family Sharing copy, and which App Store environment it came from. Your Flip Rock account ID is attached to the purchase so we know which account it belongs to.
Apple also tells our server when a purchase is refunded or a Family Sharing copy is removed, so the pack can be locked again.
We use purchase records only to unlock and restore the packs you own, never for advertising or tracking.
How it's stored and who processes it
- Backend data (your account, finds, flip dates) is stored with Supabase (our hosting/database provider) on your behalf.
- Sign-in is provided by Apple (Sign in with Apple), and Apple processes pack payments (App Store).
- Your sign-in token is stored on your device in the operating system's secure storage.
Supabase acts as a service provider/processor for the functions above. We do not share your data with anyone for advertising or sell it to anyone.
Children and families
Flip Rock is family-friendly and rated 9+, but it is not directed at children under 13 as its primary audience and is not part of Apple's Kids Category or Google's Designed for Families program. We do not knowingly collect personal information from a child under 13 beyond what's needed to sign in. A parent or guardian should set up the account. If you believe a child provided us information and you want it removed, contact us and we'll delete it.
Data retention and deletion
We keep your data while your account is active.
- In the app (Flip Rock 2.0 and later): Settings → Delete Account. This permanently deletes your account, every collector, all finds, your flip history and your purchase records right away, and revokes Flip Rock's Sign in with Apple access. A pack you bought still belongs to your Apple ID, so Restore Purchases on a new account unlocks it again.
- By email: write to fliprockgame@gmail.com and we'll delete your account and all associated data within 7 days.
Your choices
- With Sign in with Apple you can hide your email address by choosing Apple's private relay.
- You can delete your account and all its data at any time (above).
Changes to this policy
If we change this policy we'll update the effective date above and, for material changes, note it in the app.
