Symmetry 16 is designed to work without an account. The current version does not use advertising or tracking cookies.

Local game statistics
The game uses your browser’s local storage to remember small gameplay statistics such as rounds played, rounds won, and your best number of swaps. This information stays in that browser on that device. You can remove it by clearing site data in your browser.
Basic site health
Limited anonymous events
The game may send a short event label—for example, that a round started, ended, used a hint, or shared a result—plus the mode, daily or practice. These event counts help identify whether the game works as expected.
Our event function accepts only approved event labels and the two approved mode values. The application code does not read or log an IP address, user agent, referrer, request headers, or the raw request body. It does not create a user profile or persistent identifier.
Not used today
No advertising, accounts, or tracking cookies
No account data
There is no registration, login, email collection, or player profile in the current version.
No tracking cookies
The current version does not place advertising, cross-site tracking, or analytics cookies.
No personal data sale
Symmetry 16 does not sell or rent personal information.
Hosting operations
The hosting provider may process ordinary connection and security data under its own infrastructure policies. That processing is separate from the limited application-controlled game events described above.
Future changes

If advertising, new analytics, accounts, or another data practice is added later, this notice will be updated before that feature is enabled.
