Cookie Monster collects no data. It makes no network requests of any kind: no telemetry, no analytics, no crash reporting, no update checks. There is no server, no account, and no identifier.

All state (your saved sites, settings, purge journal, pending purges, and any session copies you explicitly create) is stored locally in the extension's storage, inside your browser profile, on your device. Nothing is transmitted, synced, sold, or shared with anyone. Uninstalling the extension deletes all of it.

Session copies, a feature you invoke explicitly, store the cookie values of one site in the clear in local extension storage so you can restore that session later. They never leave your device and can be deleted at any time from the popup or the settings page.
