01The TL;DR
Blox Blast Rush is a single-player block puzzle game with optional friends and leaderboards. To make those features work, we store a few things in Firebase (Google's backend service) — your scores, your chosen display name, your friend code, and an optional avatar.
That's basically it.
The current build has no third-party analytics, no location access, and no access to contacts, photos library, microphone, or camera. If you saw a permission prompt, it was Apple's, not ours.
02What we collect
The table below is the complete list. Everything maps directly to what you see in the App Store privacy nutrition label.
friendCode so people can add you.friendships/{uid}/links/*. Friend codes are looked up via a public lookup collection; only the code itself is exposed, not your other data.03How we use what we collect
Everything we collect is used only for app functionality — making the game work. Specifically:
- Save your progress so it follows you across devices and reinstalls.
- Show your name, avatar, and score on leaderboards and on your friends' lists.
- Let people add you using your friend code.
- Process in-app purchases via Apple and credit the right amount of gold.
- Reply to support emails you send us.
The current build does not use your data for analytics, profiling, modeling, recommendation systems, or any third-party purpose. Any future change to this will be reflected in an updated policy version.
04What's not in the current build
For clarity, here's what's not in the app today:
- No location data (precise or approximate).
- No access to contacts, calendar, photos library, microphone, camera, or health data.
- No third-party analytics — no Firebase Analytics, no Crashlytics, no Cloud Messaging. Only Firebase Auth and Firestore.
- No remote push. The daily streak reminder is a 100% on-device local notification scheduled by your phone — nothing goes to a server.
- No browsing history or device fingerprinting.
- We do not sell your personal information.
If any of the above changes in a future build, the policy version at the top of this page will bump and the in-app notice on launch will surface the change before it takes effect.
05Who we share data with
Three parties touch your data, all as service providers acting on our behalf:
Google (Firebase)
Firebase Authentication and Firestore store your account and gameplay data on Google Cloud infrastructure. Google processes this data on our behalf under their Firebase privacy terms.
Apple
Apple handles Sign in with Apple, Game Center leaderboards, and StoreKit purchases. They operate under Apple's privacy policy.
Other friends
If you add another player as a friend, your display name, avatar, and public score totals become visible to them. That's the point of having friends in a game.
We do not share data with anyone else, and we do not sell or rent personal information.
06Purchases
The game offers optional coin packs as in-app purchases. These are processed entirely by Apple via StoreKit. We receive a transaction receipt — enough to verify the purchase and grant the matching gold balance — but never your payment details, card number, or Apple ID password.
Refund requests are handled by Apple at reportaproblem.apple.com.
07Children
Blox Blast Rush is rated 4+ and is suitable for all ages. We do not knowingly collect personal information from children under 13 (or the equivalent age in your jurisdiction). We do not require an account to play, and the data we do store under an anonymous user ID is not personally identifying. If you believe a child has provided us with information you'd like removed, email us and we'll delete it.
08Your rights
Depending on where you live (GDPR in the EU/UK, CCPA in California, and similar laws elsewhere), you have the right to:
- Access a copy of the data we hold about you.
- Correct data that's wrong (most of this you can do yourself — change your display name or avatar in the app).
- Delete your account and all associated data.
- Object to or restrict certain processing.
- Port your data to another service.
To exercise any of these rights, email robbi@bloxblastrush.com from the address linked to your account (or, for anonymous accounts, include your friend code). We respond within 30 days.
09Retention & deletion
We keep your data for as long as your account is active. To delete your account:
- In the app: Settings → Account → Delete account. Available to everyone — anonymous players and signed-in players alike.
- By email: send a deletion request to robbi@bloxblastrush.com with your friend code.
Deletion removes your Firestore players/{uid} document, your friend-code lookup entry, and your friendship links. Game Center scores are governed by Apple and can be removed via your Game Center settings.
10Security
Your data is stored in Firestore with security rules that prevent other players from reading or modifying your private fields. Public fields (display name, avatar, friend code, public score totals) are readable by anyone with your friend code so that "add a friend" actually works. Data is encrypted in transit (HTTPS) and at rest (Google Cloud).
No system is perfectly secure. If we ever discover a breach affecting your data, we'll notify you and the relevant authorities as required by law.
11Changes to this policy
If we change anything material, we'll bump the version number at the top of this page and surface a notice in the app the next time you launch it. Continued use after a change means you accept the updated policy. Older versions are kept on request.
