CookieTin has no server and does not collect, sell or share any data. There are no accounts,
analytics, telemetry or ads, and the extension makes no network requests of its own.

• Cookies of the sites you visit, through the browser's cookies API, to show them to you and to
  change or delete them when you ask (or on the automatic cleanup you turned on).
• Site data of the current tab (localStorage, sessionStorage, IndexedDB, Cache Storage) only when
  you open the toolbar menu (to count the items) or click "Clear site data".
• The address and icon of the current tab, to show which site the menu acts on.

Nothing of this is sent anywhere. Exporting cookies creates a file or clipboard text on your
computer; what you do with it is up to you.

• Settings and the list of protected cookies (domain and cookie name, not the values) are
  stored in the browser's local extension storage.
• Nothing is stored on any server run by CookieTin.

• Access to all websites and cookies: to read and change the cookies of any site.
• Storage: settings and protected cookies.
• Alarms: the periodic cleanup, if enabled.
• Scripting and browsing data: counting and clearing site data of the current site.
• Containers (Firefox): listing your containers and their cookies.

Use "Reset everything" in the settings or uninstall the extension, which deletes everything it
stored. Cookies themselves belong to the browser and stay until you or the sites delete them.
