How TabSavior handles your data

TabSavior saves your open browser tabs into bookmark folders you can restore later. This page explains, permission by permission, what that requires and what it doesn't.

Effective 2026-09-10 Applies to TabSavior v1.0.0 Platform Chrome / Manifest V3

In one sentence: TabSavior stores everything on your own device using your browser's built-in bookmarks and local storage. It has no server, no account system, and no telemetry — your tabs, titles, and URLs are never sent anywhere.

What TabSavior accesses, and why

Chrome requires an extension to declare every capability it uses. Here is what TabSavior declares and what each one is actually used for:

Permission	What it's used for
`tabs`, `windows`	Reading the titles and URLs of your currently open tabs and windows when you click "Save all windows," so they can be turned into bookmarks.
`tabGroups`	Reading the names of any Chrome tab groups you've created, so saved folders can optionally mirror your tab groups.
`bookmarks`	Creating, reading, and deleting the bookmark folders that hold your saved sessions, and restoring them as tabs later. Your browser's bookmarks are the only place saved tab data lives.
`storage`	Keeping a small local index — timestamps, tab counts, save status — in the browser's local extension storage, so the session list loads instantly. This index never leaves your device.

Where your data lives

Saved tabs (titles and URLs) become ordinary bookmarks in your browser's own bookmark manager, under a folder TabSavior creates. You can view, move, or delete them any time — with or without TabSavior installed.
Session metadata is kept in chrome.storage.local, which stays on your device and is not synced to any TabSavior-run account, because none exists.
TabSavior has no backend server. There is nowhere for your data to go.

What TabSavior does not do

It does not transmit tab titles, URLs, or browsing data to any server.
It does not use analytics, telemetry, or crash reporting. Nothing is collected by default, and there is currently no opt-in telemetry feature to turn on.
It does not require or support account creation or sign-in.
It does not show ads or share data with advertisers or any other third party.
It does not read the content of the pages you visit — only tab metadata (title, URL, pinned state, tab group name).

Retention and deletion

A saved session persists until you delete it — either from TabSavior's session list or directly in your browser's bookmark manager. Deleting a session in TabSavior removes both the bookmark folder and its local metadata entry. Uninstalling the extension leaves existing bookmarks untouched, since they belong to your browser, but clears TabSavior's local metadata index.

Imported sessions

TabSavior's import feature reads a file you choose (for example, a Session Buddy export or an earlier TabSavior export) entirely inside your browser. It is never uploaded anywhere as part of that process.

Children's privacy

TabSavior is a general-purpose productivity tool not directed at children and does not knowingly collect data from anyone, regardless of age — it does not collect data at all.

Changes to this policy

If a future version of TabSavior changes what it does with data — for instance, an opt-in sync feature — this page will be updated first, and the version and date above will change accordingly. Any new data collection will remain off by default and require explicit opt-in.
