Cookies & site storage

Optional sign-in uses essential HTTP-only session cookies. OAuth sign-in, when configured, also uses security state cookies. Signing out ends the current session; account settings can sign out other devices. These are not advertising or tracking cookies.

The current public tools do not set tracking cookies or load advertising scripts. Theme preference and recent tool identifiers use local storage.

No nonessential analytics or personalized advertising is enabled. Adding an ad provider requires a verified consent implementation and policy configuration. Clear this site’s browser storage to reset local preferences.
