What stays on your device
Playing never needs an account: you play anonymously, and signing in is optional (see "Signing in" below). Your progress is saved on this device, in the app's local storage: the game in progress, best scores, level progress, daily challenge results, stats and achievements, coins and items, your selected themes and your settings. Uninstalling the app deletes it unless you are signed in with cloud save (below).
In versions with online features, the app also talks to our game server: it registers this install with a random player ID (no name, email or device identifier), and keeps your coin balance, verified scores and level stars there so they cannot be lost or faked. Versions without online features send none of this to us.
Signing in (optional, for leaderboards)
You only need to sign in to appear on the leaderboards. You can sign in with an emailed link or code, Sign in with Apple (iPhone) or Google (iPhone and Android). There are no passwords.
- Email. We use your address to send the sign-in email (link and 8-character code) through our email provider, Resend, and to recognise you when you sign in again. We store the address encrypted, plus a keyed fingerprint of it used for look-ups; we never store the link or code themselves, only one-way hashes that expire after 15 minutes.
- Apple or Google. We receive a signed token from Apple or Google that tells us a stable account identifier and, if you share it, your email address (Apple lets you share a private relay address instead). We store only a keyed fingerprint of the identifier and, if given, your address encrypted. We never receive your Apple or Google password.
- Your nickname. Leaderboards show the nickname you choose, never your email.
- Several devices. You can be signed in on more than one device; they share one coin balance and one leaderboard entry. When you sign in on a device that has been playing anonymously, its coins and level stars move into your account.
- Signing out. "Sign out on this device" forgets the sign-in here; "Sign out everywhere" signs out every device. Your account stays until you delete it.
- To stop abuse we count sign-in attempts per network address and per email fingerprint for up to an hour; we store a one-way hash of the address, not the address itself.
Cloud save (signed-in players only)
When you are signed in, the app keeps a copy of part of your progress on our game server so another device signed in to the same account picks it up, and so a reinstall can restore it. Anonymous play never uploads it. The copy holds: your settings (sound, music, haptics, calm mode, reduce motion, colour-blind symbols, placement preview, app theme), your selected block theme, whether you have seen the introduction, your daily challenge scores and streak, Streak Shields, and your play stats (games played, totals, best combo, top scores) from which achievements are worked out. It holds no name, email or device identifier and is tied only to your account. Coins, purchases and level stars are already kept by the server as described above; a game in progress is not uploaded. The copy is at most 64 KB. Signing out leaves your progress on the device; deleting your account erases the cloud copy.
Deleting your account
You can delete your account at any time in the app: Settings → Account → Delete account, then type DELETE. It takes effect at once. Without the app, email blokkit@mycareerocket.com from the address you sign in with and we will delete it within 30 days and confirm by email. Step-by-step instructions are also at https://blokkit.app/delete-account.
- Deleted for good: your account, your email address, your sign-in methods (the fingerprints of your address and of your Apple or Google identifier), any sign-in emails not yet used, your nickname, your leaderboard scores and verified runs, the level stars saved with your account, your cloud save, and the coins in it (bought coins included; they are not restored).
- Kept, without anything that identifies you: purchase records (the store's receipt reference, product and date) and the coin history of the account. App stores need them to process refunds and chargebacks, and we need them to keep an accurate record of purchases. After deletion they are tied only to a random ID that no email, sign-in or nickname points to, and we keep them for as long as tax law and the app stores' rules require.
- Your devices: every device is signed out. The device you deleted from starts a fresh anonymous game with a new Coin ID; progress saved on a phone stays on that phone until you uninstall the app.
- Sign-in attempt counters (one-way hashes) expire within an hour and are not linked to your account. If you sign in again later with the same address, you start a new, empty account.
Ads and consent (Google AdMob)
Blokkit shows ads through Google AdMob: rewarded ads you choose to watch, and interstitial ads between games. You can remove interstitial ads with the one-time Remove ads purchase.
- Before any ad is requested, the app asks Google's User Messaging Platform (UMP) whether consent is needed where you live, and shows Google's consent form when it is. Ads are not requested until UMP says they may be.
- On iOS the app then asks for App Tracking Transparency permission. Saying no still lets you play and watch ads; they are just not personalised by tracking.
- You can change your ad choices at any time in Settings, "Privacy options · Ads" (shown when your region requires it).
- Google and its ad partners may collect device identifiers, IP address, approximate location and ad interaction data to serve, measure and (with consent) personalise ads. See Google's policy: https://policies.google.com/technologies/partner-sites
Purchases
Coin packs, item packs and Remove ads are bought through Google Play or the App Store. The store handles payment; we never see your card or account details. The app receives a purchase record from the store, uses it to credit what you bought, and keeps that credit in local storage so a purchase is never counted twice. "Restore purchases" asks the store again for purchases you already own.
Analytics
The app currently sends no analytics of its own. Ad events are only written to the device log, in development and test builds.
Children
Blokkit is for ages 13 and over. It is not directed at children, it is not part of Google Play's Families program, and ad requests are not marked as child-directed. We do not knowingly collect personal data from children under 13. If we learn that we have, we delete it.
Changes and contact
If this policy changes, the new version will ship with an app update. Questions: blokkit@mycareerocket.com.
