ECHO is a memory game that runs entirely in your browser, with no server-side component.
The game does not collect names, email addresses, location, or any other personal data. There is no sign-up or account system.
The current round number, sequence length, and mistake count are held only in the page's memory for the length of the session. After the page is reloaded, these values reset and are never sent anywhere.
The only external request is loading the Archivo Black and Inter fonts from Google Fonts for correct text rendering. There is no analytics, advertising, or tracking script.
ECHO sets no cookies of its own and does not use browser storage to save progress between sessions.
The game is designed for a general audience who enjoys attention and memory puzzles, with no age-restricted content.
Questions about privacy can be sent to the developer of ECHO.
