Privacy Policy — Tab Session Manager

Last updated: July 2, 2026

Summary

Tab Session Manager saves and restores your browser sessions (windows, tabs, and tab groups) entirely on your device. Your data never leaves your browser. We do not collect, transmit, or sell any personal data.

What data we access

Tab URLs and titles — to save and restore your sessions. This data is stored locally in your browser's IndexedDB and is never transmitted to any server.
Tab group information (title, color, collapsed state) — to preserve your tab group setup when restoring sessions.
Window state (position, size, normal/minimized/maximized/fullscreen) — to restore windows as they were.
Window names — custom names you assign to windows in the edit mode. Stored locally only.

What we do NOT access

We do not read the content of any web page.
We do not use content scripts. No code runs on any web page you visit.
We do not have host permissions. We cannot access any website's data.
We do not use analytics, telemetry, or tracking.
We do not transmit any data to any server. There is no server.

Storage

All session data is stored locally in your browser using:

IndexedDB — for session records (the full snapshot data)
chrome.storage.local — for lightweight settings and metadata

We request the unlimitedStorage permission to prevent Chrome from silently evicting your session data when storage quota is exceeded, which is the most common cause of data loss in other session managers.

Permissions explained

Permission	Why we need it
`tabs`	Read tab URLs and titles to save sessions; create tabs when restoring
`tabGroups`	Save and restore tab group titles, colors, and collapsed state
`storage`	Store session data and settings locally
`unlimitedStorage`	Prevent Chrome from evicting session data due to quota limits
`alarms`	Schedule periodic auto-snapshots (every 15 minutes)
`favicon`	Display website favicons in the session list UI

Data export and deletion

You can export any single session or all sessions as a JSON file at any time from the extension popup.
You can import previously exported sessions (coming soon).
Deleting a session moves it to trash (7-day retention, restorable — coming soon).
Uninstalling the extension removes all data. Export before uninstalling if you want to keep your sessions.

Open source

This extension is open source. You can audit the full source code to verify these claims.

Changes to this policy

We will update this policy if the extension's data practices change. Any future cloud sync feature (planned for v1.1) will be opt-in and will require explicit user consent, and this policy will be updated accordingly before that feature ships.
