PRIVACY

NIRCOSI is local-first. Your careers, scores, streaks and settings are stored in your browser's local storage on your own device. They are not uploaded, synced or sold, because they never leave the browser.

There are no accounts and no sign-ins, so there is no personal profile to hold. We do not run advertising trackers or third-party analytics on these pages.

Clearing your browser's site data permanently deletes your saved paths and personal bests. There is no backup — that is the price and the point of keeping everything local.

If a future feature ever needs server-side storage (for example, global leaderboards), it will be opt-in, clearly labeled, and this page will be updated before it ships.
