Privacy Policy
Last updated: 26 September 2026
Purple Delta is designed to respect your privacy.
What we store
- Saved setups and your garage are kept on your device and synced to your account so they follow you across devices. App preferences stay on your device.
- Account details (username and email — and, if you sign in with Google, the name and profile picture on your Google account) and the community content you post — setups, comments, likes and reports — are stored on our servers so they can be shown to other players and kept moderated. Your username, and whether your account has Pro, are public.
- If you remove a tune you published, it disappears from the Community for everyone. It is erased from our servers when you delete your account.
How your account is secured
- Sign-in is handled by our authentication provider. Passwords are encrypted (hashed) and are never visible to us or stored in the app.
- We use trusted service providers to run the service, and each receives only what it needs: Supabase (hosting, sign-in and our database, in the EU), RevenueCat (your subscription purchases, so it can tell us whether your subscription is active), Resend (account emails such as password resets, and a copy of each report or feedback message you send, delivered to our support inbox), and Apple and Google (payments, and sign-in if you choose Sign in with Apple or Google).
Purchases
- Subscriptions are processed by the Apple App Store or Google Play. We never see your payment details. Our subscription provider, RevenueCat, tells us whether your account’s subscription is active, and we store that with your account.
Data we do not collect
- We do not collect your contacts or location. If you choose Sign in with Google, Google may use your IP address to estimate your general location to protect the sign-in.
- We do not sell or share your personal information.
Third-party data
- Car and track reference data is compiled from public community sources and used for in-app reference only.
Deleting your account & your data
- You can delete your account at any time from Profile › Manage Account › Delete account.
- This permanently removes your profile, email address, saved setups, garage, favourites, owned-car list, votes, likes and reports from our servers, and clears your data from this device. It cannot be undone.
- It also erases the tunes you published to the Community Garage and the comments you wrote, together with other players’ replies, votes and favourites on them.
- A store subscription is billed by the App Store / Google Play and is separate — cancel it in your store account.
- Can't access the app? Email support@purple-delta.com to request deletion of your account and data.
Some things stay after deletion:
- Your username can still appear in other players’ comments that mention you.
- Suggestions and feedback you sent stay, no longer linked to you.
- Copies of reports and feedback you sent stay in our support inbox, with your username.
- RevenueCat, our subscription provider, keeps its record of your subscription purchases, and Apple and Google keep their own purchase and tax records.
- A record of each subscription event (its type and your account ID) is kept for up to 30 days, then deleted automatically.
- Our service providers keep their own short-term service logs, such as sign-in and email-delivery logs, and delete them on their own schedule.
