Privacy policy
Last updated: 11 November 2026 · Version 1.0.0 · Publisher: isabilov.
Short version: Tabkin has no servers and sends nothing anywhere. The tabs you save and their history stay in your Chrome on this device. Your settings, including the list of sites that are never saved, are also stored only on this device (not synced). Backup files are written only to your own computer. Tabkin does not work in Incognito windows and never stores private tabs. The only time anything goes out is when you click a link (Report a bug or by isabilov.).
What Tabkin reads
- Your open tabs: address, title, pinned state, window and Chrome tab group (name and colour). Tabkin reads them to show the Open tabs list, to count what Save all tabs will save, to find duplicate tabs and to save the tabs you choose. It reads them only inside Chrome; it does not read page content, form fields, passwords or cookies, and it does not run any code inside web pages.
- Site icons come from Chrome's own icon cache on your device. Tabkin does not download them.
What Tabkin saves (on your device only)
| Data | Where | Why |
|---|---|---|
| Saved groups: name, colour, star, date, and each tab's address and title | chrome.storage.local | Your saved tabs. |
| Trash: deleted groups and tabs | chrome.storage.local | So you can restore them. Removed for good after 30 days, or when you click Delete forever. |
| History: a copy of your saved groups at each change, with a short description | chrome.storage.local | Backup and restore → History. Kept for 30 days (at most 400 versions and 100 MB); older versions are removed by a daily clean-up even when nothing changes. |
| Undo information for your last actions | chrome.storage.local | The Undo button. Kept up to 15 minutes, then removed. |
| Daily backup file status (date, file name, last error) | chrome.storage.local | The status line on the Backup page. |
| Settings: keep tabs open, right-click menu, open on start, daily file on/off, sites that are never saved | chrome.storage.local | Your settings, on this device only. They are not synced to your Google account. |
| Recently closed tabs (up to 20), the last message shown, which Chrome group came from which saved group | chrome.storage.session | Open tabs → Recently closed. Cleared when Chrome closes, and also when the extension is reloaded, turned off or updated. |
Tabkin has no servers, no analytics, no tracking, no ads, no account and no remote code. Nothing is uploaded.
Files Tabkin writes
- Daily backup file (on by default; turn it off in Backup and restore): once a day, and only if something changed, Tabkin saves
Downloads/Tabkin/tabkin-YYYY-MM-DD.jsonwith your saved groups and Trash. It is a normal file on your computer; Tabkin does not upload it. If your Downloads folder is synced by another app (for example iCloud Drive, Google Drive for desktop or Dropbox), that app copies it the same way it copies any file. - Download backup now and Export → Full backup save
Downloads/Tabkin/tabkin-backup-YYYY-MM-DD-HHMMSS.json(a new file each time, never replacing the daily file). Export → Text list saves a plain list of links. - Import and Restore from file read only the file you pick or the text you paste, show what will be added, and only add to Tabkin (nothing is removed; you can undo it).
Links
- Report a bug opens a Google Form with the extension name and version filled in. Tabkin does not put any page address or tab data in that link. What you type in the form goes to Google Forms and to the publisher; Google's privacy policy applies to the form.
- by isabilov. opens isabilov.com.
- Change shortcuts opens Chrome's own shortcut settings page.
Permissions and why
| Permission | Why |
|---|---|
| tabs | Read the address and title of open tabs to save them, list them and find duplicates; close and reopen them when you ask. |
| tabGroups | Keep a Chrome tab group's name and colour when you save it, and bring the group back when you open it. |
| storage, unlimitedStorage | Keep your saved tabs, Trash and History on your device; large libraries (thousands of tabs with 30 days of history) need more than the default space. |
| downloads | Write the daily backup file and Download backup now. |
| alarms | Check once an hour whether today's backup file is due and clear Trash older than 30 days. |
| contextMenus | The right-click menu (Save this tab, Save this window, Never save this site…). You can turn it off in Settings. |
| favicon | Show site icons from Chrome's own cache. |
| offscreen | Build the backup file for very large libraries (over about 2 MB) inside Chrome. |
No host permissions: Tabkin cannot read or change the content of any website. Incognito: not allowed (Tabkin is not available in private windows).
Deleting your data
Delete groups and empty Trash (Delete forever), or remove the extension: Chrome then deletes everything Tabkin stored. Backup files in your Downloads folder are yours; delete them like any file. Note: copies of deleted groups stay in History until they are older than 30 days.
Children
Tabkin is a general-purpose tool and is not directed to children.
