Privacy Policy
This Privacy Policy explains how blub (the "app"), a casual tile-matching puzzle game, collects, uses, and shares information. We collect only what is needed to run the game and your account. By using blub you agree to this policy.
1. Information we collect
a. Sign-in info (optional)
You can play blub anonymously with a local nickname only. If you choose to sign in to keep your account across devices, we receive from Apple or Google:
- A stable, anonymous subject identifier (Apple
sub/ Googlesub) - The email address you authorize (you can use Apple's Hide My Email)
- Your name, if provided (used only as a nickname suggestion)
We store the subject identifier and your chosen nickname on our server. Email is used only for the sign-in handshake and is not stored long-term unless required by Apple / Google's protocols.
b. Gameplay data
- Nickname, scores (Time Attack / Endless / 1 vs 1), level reached, taps, ELO rating, win/loss/draw counts
- Daily challenge attendance (ONE SHOT) and streaks
- Heart pool state for the Endless mode (stored locally on your device)
c. Diagnostics
- Self-hosted, anonymous event analytics (e.g.,
app_open,game_started,game_over) — used only to understand which modes are played and to size servers - Crash and error reports (technical stack traces) — used only to fix bugs
d. Advertising (rewarded only)
blub uses Google AdMob only for an opt-in rewarded video in Endless mode (the "Watch ad to revive / get a heart" button). When you tap that button, Google AdMob receives standard advertising data:
- Your device's advertising identifier (IDFA on iOS / AAID on Android)
- IP address, device model, OS, and rough region for ad delivery
On iOS, the system asks for App Tracking Transparency permission before any identifier-based ads. You can decline; non-personalized ads still work.
2. How we use it
- To run the game and your account
- To compute leaderboards, ELO ratings, and daily streaks
- To diagnose crashes and improve gameplay
- To deliver the rewarded ads you choose to watch
We do not sell your personal data and do not use it for cross-app profiling beyond what AdMob does for the rewarded ad you opt into.
3. Third parties
- Apple — Sign in with Apple (privacy)
- Google — Sign in with Google (privacy)
- Google AdMob — opt-in rewarded ads only (privacy)
blub does not use any other third-party analytics or marketing SDKs.
4. Data storage and security
Gameplay data is stored on our own server. Network traffic is encrypted with HTTPS / WSS. Sign-in tokens are verified against Apple / Google public keys and never stored. Hearts and local nicknames are stored on your device only.
5. Children
blub is intended for users 13 years of age and older. We do not knowingly collect data from children under 13. If you believe a child has provided us data, contact us and we will delete it.
6. Your rights
You can request to access or delete your account data at any time by emailing us at the address below. Deletion removes your player record, scores, and ratings from our server; advertising data held by AdMob can be managed in your device's privacy settings.
7. Changes to this policy
If we materially change this policy we will update the "Last updated" date above and, where appropriate, surface the change in the app.
8. Contact
