Privacy Policy
Effective date: May 26, 2026. This policy explains how the site handles local data, analytics, ads, and contact messages.
Local game data
The MVP does not require an account. Game settings, control preferences, local bests, theme preference, recent replay events, daily challenge attempts, and last-game data may be stored in your browser using localStorage. Examples include tetris.settings.v1, tetris.controls.v1, tetris.best.classic.v1, tetris.best.sprint40.v1, tetris.best.daily.v1, tetris.replays.v1, tetris.theme.v1, and tetris.lastGame.v1.
Analytics and ads
A deployment may use privacy-friendly analytics, Microsoft Clarity, GA4, AdSense, or Media.net. Analytics should track aggregate events such as game_start, game_over, mode_change, settings_open, fullscreen_enter, share_click, daily_complete, and sprint_complete. The site should not send every move to analytics.
Cookies
The core game does not need cookies. Analytics or ad providers may set cookies according to their own policies if enabled by the site operator. Ads must not cover the canvas or controls.
Contact messages
If you contact the site operator, the information you provide is used to respond to the request and manage abuse or spam. Do not send sensitive personal information through the contact page.
Frequently Asked Questions
Do you collect account information?
