Privacy Policy
Last updated October 24, 2026
This policy explains what data the Spin Vault app for iPhone collects, why, and what you can do about it. Spin Vault is made by Abiezer Fraga, an independent developer, who is responsible for the data described here. If you have a question, email abiezer.fraga@gmail.com.
The short version
- Spin Vault has no ads and no tracking. It doesn't share your data with advertisers or data brokers.
- You can use the app as a guest without giving a name or email.
- If you sign in, your collection syncs through Google Firebase so it shows up on your other devices, including Spin Vault on Android.
- You can delete your account and its data from inside the app at any time.
What we collect
| Data | When | Why |
|---|---|---|
| An account ID | Whenever you use the app, as a guest or signed in | To run your account and keep your data separate from everyone else's |
| Name and email | Only if you sign in with Apple or Google and they share it | To show which account you're signed in with |
| Your collection, wishlist, combos, decks, notes, tags and settings | When you add or change them | To make the app work and, if you're signed in, sync between devices |
| Battle history | When you record a battle | Stored on your device. Synced only if you turn on Battle History Sync while signed in |
| Premium status | When you buy or restore Premium | To unlock Premium features |
If you use the app as a guest, your content stays on your device and isn't synced.
Purchases
Premium purchases and subscriptions are handled by Apple. We never see your card or payment details. Apple tells the app whether you have an active purchase, and that's all we use. You can manage or cancel subscriptions in your Apple account settings.
Who processes your data
- Google Firebase (Authentication and Cloud Firestore) stores account and sync data. See Firebase's privacy information.
- Sign in with Apple and Google Sign-In are used only if you choose them to sign in.
- Apple processes App Store purchases.
We don't sell your data or use it for advertising.
How long we keep it
We keep your account data for as long as you have an account. When you delete your account, your account and the data synced to it are deleted from our servers. Data saved only on your device is removed when you delete it or uninstall the app.
Your choices
- Delete your account: Settings > Privacy & Data > Delete Account. Guests can use Erase Guest Account.
- Stop syncing battles: turn off Battle History Sync in Settings.
- Edit or delete content: remove any item, combo, deck or battle from inside the app.
- Revoke sign-in access: from your Apple ID or Google account security settings.
Depending on where you live, you may have other rights, such as getting a copy of your data. Email us and we'll help.
Children
Spin Vault isn't directed at children under 13, and we don't knowingly collect personal information from them. If you think a child under 13 has given us personal information, email us and we'll delete it.
Changes
If this policy changes, we'll update the date at the top of this page. For big changes we'll also mention it in the app's release notes.
