Privacy Policy
Block Matrix Puzzle · Last updated 15 October 2026
This policy explains what Block Matrix Puzzle collects, why, and what you can do about it. It is written to be read, not to be survived.
The short version: the game works offline, there is no account to make, and nothing you do in it is tied to your name. Two Google services receive anonymous information about crashes and general usage so the game can be kept working.
What stays on your device
Your high score, coin balance, unlocked board themes, daily streak and settings are stored on the device only. They are never uploaded. Deleting the app deletes them, and there is no way to restore them afterwards.
What is sent, and to whom
| Service | What it receives | Why |
|---|---|---|
| Google Firebase Analytics | Two anonymous events — roughly how high scores fall into ranges, and roughly how many games have been played. Plus what Firebase collects automatically: device model, operating system version, app version, country, and a random identifier for the app installation. | To understand whether the game is too hard or too easy, and whether people keep playing. |
| Google Firebase Crashlytics | Crash reports: where in the code the game stopped, device model, operating system version, and how much memory was free. | To find and fix crashes. |
None of this includes your name, email address, phone number, contacts, photos, location or advertising identifier. The installation identifier is random, is not linked to you, and is replaced if you delete and reinstall the game.
Advertising
This version of the game shows no advertisements and collects no advertising identifier. If advertising is added in a future version, this policy will be updated before that version is released, and the app's store listing will say so.
Purchases
There are none. The game is free and contains no in-app purchases.
Notifications
If you allow notifications, the game schedules reminders on the device itself. No server is involved and no notification data leaves the phone. You can turn them off in the game's settings or in your device settings.
Children
The game is suitable for all ages but is not directed at children under 13, and we do not knowingly collect personal information from them. There is nothing in the game that asks for personal information from anyone.
Your choices
- Stop the analytics and crash reporting: delete the app. Because nothing is tied to an account, that ends the collection entirely.
- Reset the installation identifier: delete and reinstall the game.
- Notifications: turn them off in the game's settings or in your device settings.
Because the data is anonymous and not linked to you, we cannot look up, export or delete the records of one particular person — there is no way to tell which records are yours.
How long it is kept
Firebase Analytics data is retained for 14 months and then deleted automatically. Crash reports are kept for 90 days. These are Google's defaults for the services as configured.
Where it is processed
Google processes this data on its servers, which may be outside your country. Google's own privacy policy covers that processing: policies.google.com/privacy.
Changes
If this policy changes, the date at the top changes with it. Material changes — new data collected, or a new service receiving it — will be reflected here before the version that makes them is released.
