Tab Retitler privacy policy
Last updated October 16, 2026
Tab Retitler keeps everything on your computer. It doesn't send your data anywhere, has no account, and uses no analytics or tracking.
What Tab Retitler reads
To rename tabs and change their icons, Tab Retitler reads, only on sites you have allowed it to run on:
- the page's address and title;
- text on the page that your rules point to, such as a heading or a status label;
- the site's icon, so a badge can be drawn on it;
- the colors of labels on the page, to suggest icon colors while you build a rule;
- the layout of what's on screen, to draw small previews of a site's tabs while you teach a rule on all of them at once. These are drawn on your computer and kept only while that view is open.
It also reads the address and title of the tab next to its side panel, to show whether one of your rules applies to it.
What Tab Retitler stores
Your rules, and the examples you give when building a rule by example, are saved in Chrome's local storage on your computer. Examples can include text from the pages you used. A copy of each allowed site's icon is also kept in Chrome's session storage, for the editor's previews, and is cleared when Chrome closes. You can delete any rule, along with its examples, at any time, and removing the extension deletes everything it stored.
What Tab Retitler shares
Nothing. None of what Tab Retitler reads or stores leaves your computer. The only thing it ever downloads is a site's own icon, from that same site, so it can draw a badge on it. It doesn't sell, transfer or use your data for anything other than renaming and marking your tabs.
When you choose to share rules, Tab Retitler gives you a code or a file to send yourself. These contain only the rules' settings, never the examples or page text. Who you send them to is up to you.
Site access
Tab Retitler has no access to any site when installed. It asks Chrome for access one site at a time, when you set up a rule for that site, and you can remove access at any time from Chrome's extension settings.
Open source
Tab Retitler's code is public, so you can check all of this yourself: github.com/ignaciofh9/tab-retitler.
Changes
If this policy changes, the new version will be posted here with a new date.
