Privacy policy — Dusk Blocks

Last changed on 24 September 2026.

Dusk Blocks collects no personal information. It has no account and no advertising. The game works offline: it carries its own rules, its own art and its own sound, and it keeps its own state — the rules you play under, how you like it to look, your high scores, the Badges you have earned and the lessons it has already shown you — on the device you play on, and nowhere else. None of it identifies you, and the publisher can neither read it nor copy it. You erase all of it by clearing the site data for the game in your browser, or by uninstalling the app.

If you allow it, the game sends anonymous play statistics and diagnostics. It asks you once, the first time you open it, and it sends nothing before you answer Allow. The statistics are how often you play and how long a Run lasts, with the score and the level that Run reached, the version of Dusk Blocks you are playing and whether you are playing in a browser or in the Android app. The diagnostics are a crash report or a warning the game catches about itself: an error message, the platform, the Dusk Blocks version, the browser and operating system, and — on Android — a stack trace read against a mapping file the publisher keeps, so it can be read without naming you. It sends no name, no address, no contact detail and nothing you have typed, and no identifier ties one diagnostic report to another or to the play statistics above.

The statistics go to Google Analytics. The processor is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Your copy of the game is counted under an app-instance identifier that Google Analytics gives it. That identifier names the installation and not you, and it is given to nobody else. Google Analytics keeps the statistics for 14 months and then erases them.

The diagnostics go to Sentry. The processor is Functional Software, Inc. (doing business as Sentry), 45 Fremont Street, 8th Floor, San Francisco, CA 94105, United States, which stores this game's reports in the European Union region and keeps them for 90 days before erasing them. A diagnostic report carries no app-instance identifier and no other identifier. On Android, a change to this answer reaches the diagnostics you send only the next time you open the app; on the web it takes effect at once.

Your answer is not final. You turn the statistics and diagnostics off at any time in Settings: the Anonymous play statistics and diagnostics row, under Privacy. The game then sends no more, and it erases the app-instance identifier, so nothing joins a later Run to an earlier one.

This notice is written for Article 13 of Regulation (EU) 2016/679, the General Data Protection Regulation. It gives you the controller and the way to reach them. The lawful basis for the statistics and the diagnostics is your consent, which you give by Allow and take back in Settings, and there is no other processing to declare.
