Tabbins Privacy Policy

Last updated: November 11, 2026

Tabbins is a Chrome extension that saves and organizes your windows, tabs and tab groups. It has no servers, analytics, advertising or tracking. The developer never receives your data.

What Tabbins stores, and where

• On your device: the titles, URLs and favicon addresses of tabs you save, the tab groups you name, your collections, spaces, tags and settings, and automatic snapshots of your open windows for crash recovery. This is kept unencrypted in Chrome’s extension storage in your browser profile.
• In your own Google Drive, only if you turn on sync: an encrypted copy of the same data and daily encrypted backups. Data is encrypted on your device with AES-256-GCM before upload. The key is protected by your passphrase and recovery key, which are never stored or sent anywhere, so neither Google nor the developer can read the contents.
• In Chrome sync, only if you turn on sync and live sync: a tiny marker (a random device id and a timestamp, no tab data) that tells your other Chrome devices to check Drive for changes.

Space live sessions (tab URLs, titles, pinned state and tab group metadata) are saved automatically on this device when you link a space to a Chrome window. These live sessions and window links are not uploaded to Drive or Chrome sync; saved collections and space names continue to use the existing optional encrypted sync. Incognito windows are not linked or captured.

Duplicate cleanup retains the removed tabs’ URLs, titles, metadata and original locations for selective recovery for 30 days. Saved-tab cleanup records are included in optional encrypted Drive sync; records of tabs closed in Chrome remain only on the originating device. Each cleanup shows its expiry date. Older backups can still contain these records after their active expiry.

Google account data

When you sign in for sync, Tabbins uses Chrome’s identity API with these Google permissions:

• drive.appdata: a hidden app folder for the encrypted sync file.
• drive.file: only files Tabbins creates, such as the backups folder. Tabbins cannot see your other Drive files.

Your Google email, name and profile photo are read to show which account is connected. They stay in your browser. Sign-in tokens are managed by Chrome and are not stored by Tabbins; signing out revokes them.

Network requests

Tabbins contacts only:

• Google’s Drive and OAuth services, when sync is on.
• Google’s servers, to load your profile photo.
• The website of a saved tab, to load its icon when that tab is reopened as a lazy-loading placeholder.

Bookmarks, open tabs and browsing activity are read only to provide the features you use, and never leave your device except inside your own encrypted Drive files.

Sharing and use

Tabbins does not sell, share or transfer your data to anyone, and does not use it for advertising, credit decisions or any purpose unrelated to managing your tabs. Use of Google user data complies with the Chrome Web Store User Data Policy, including the Limited Use requirements.

Your control

• Delete saved items in Tabbins at any time; Trash empties after 30 days.
• Uninstalling the extension removes all local data.
• Sign out in Settings to stop sync. Delete the “Tabbins Backups” folder in Drive to remove backups, and remove Tabbins under Google Account › Third-party connections to delete the hidden sync file.
