Is Session Sync safe?

Clean risk

Session Sync saves open tab URLs and titles in local browser storage when auto-save history is enabled.

The optional Auto-save History setting periodically reads normal browser windows and stores each tab's URL, title, pinned state, container ID, and tab group details under local history entries. Private windows are skipped unless the user enables Save private windows; the reviewed code stores these snapshots in browser.storage.local and does not show an external recipient for this history data.
