Last updated: 7 July 2026 · Applies to: the TabArk — Tab Session Backup Chrome extension.
The short version: TabArk keeps everything on your device. It does not have a server,
it does not require an account, and it never sends your data anywhere. There is no tracking, no
analytics, and no third parties.
What TabArk stores
To back up and restore your browsing sessions, TabArk stores the following locally in your
browser (via the browser's IndexedDB and extension storage):
The URLs and titles of your open tabs, grouped by window (so a session can be restored).
A small favicon reference for display (TabArk shows a generic placeholder icon and
does not fetch icons from the web).
Your settings (e.g. how many sessions to keep) and a pointer to a backup folder you choose.
TabArk does not read, store, or transmit the content of any web page. It only
records tab addresses and titles — the minimum needed to reopen your tabs.
Incognito
TabArk never captures Incognito windows or tabs.
Where your data goes
Nowhere, by default. All data stays in your browser's local storage on this device.
TabArk makes no network requests of any kind.
Optional owned-file backup. If you choose a backup folder, TabArk writes a
backup file only to that folder you selected, on your own computer, using the browser's
File System Access feature. You can revoke this at any time. Nothing is uploaded.
Export/Import. If you use Export, TabArk creates a file you save yourself; if you use
Import, TabArk reads a file you select. These stay entirely on your device.
What TabArk does NOT do
No servers, no accounts, no sign-in.
No analytics, telemetry, advertising, or fingerprinting.
No selling, sharing, or transferring of your data to anyone.
No use of your data to determine creditworthiness or for lending.
No remotely-hosted code — all of TabArk's code ships inside the extension.
A note on uninstalling
Because TabArk stores your sessions in the browser, uninstalling the extension (or resetting
your Chrome profile) deletes that in-browser data, exactly as Chrome deletes any extension's
storage. The only copy that survives an uninstall is one you have saved yourself using
Export or the owned-folder backup — which is why TabArk makes those
features prominent. TabArk cannot recover data that only lived in the browser after it has been removed.
Permissions and why they're needed
tabs — to read the URL and title of your open tabs so they can be saved and
restored. TabArk never reads page content and never transmits tab data.
storage / unlimitedStorage — to save your session
backups and settings locally, and to let your history grow without silently dropping old sessions.
alarms — to briefly wake the extension to finish saving a backup after tab
activity and to trim old backups. No network, no tracking.
TabArk requests no host permissions and accesses no websites.
Changes to this policy
If TabArk's data practices ever change, this policy will be updated and the change will be disclosed to
users before it takes effect.
