Chrome Sync is a privacy-first browser extension for syncing bookmarks, open tabs, and extensions across browser profiles. All sync data is end-to-end encrypted client-side (AES-GCM-256) using your secret passphrase before leaving your device. The sync server cannot read your data.
2. Information Processing
Synced Data (Tabs, Bookmarks, Extensions): Encrypted client-side before sync. Stored as opaque encrypted payloads on the server and automatically purged after 7 days of inactivity.
Passphrase & Credentials: Your passphrase is stored locally and never sent to the server. Authentication tokens are hashed (SHA-256).
No Tracking or Analytics: Zero telemetry, Google Analytics, or tracking scripts. Browsing history is never collected.
No Third-Party Sharing: Data is never sold, monetized, or shared with third parties.
