The short version: DECADES doesn't collect your name, email, or any personal information. There are no accounts, no logins, and no ads. Your game progress lives in your own browser.

Your Browser's Local Storage

Your game state — streak, score history, difficulty, and puzzle progress — is stored entirely on your own device. It never leaves your browser and can be cleared any time from the Settings menu.

Anonymous Play Counts

When you load, solve, or share a puzzle, our server logs a simple anonymous event. No IP address or personal information is attached. These counts power the community stats bar.

Google Analytics

We use Google Analytics for general traffic patterns. It may collect approximate location and browser info via cookies. You can opt out via the Google Analytics Opt-out Add-on.

Background Photos

Daily images load from picsum.photos. Their servers may log your IP as part of standard operation. We do not receive or store this information.

We do not collect your name, email, or any contact information. We do not require account registration. We do not sell or share any data. We do not track your activity across other websites. The game is currently ad-free, though we may introduce non-intrusive advertising in the future to support ongoing development.
