Privacy policy
Effective 12 November 2026
Short version: the AdTabBlock extension does not collect, sell or share any data about you or what you browse. Everything it does happens inside your browser.
What the extension stores
AdTabBlock keeps a few things in your browser's own extension storage, on your computer only:
- The sites where you paused AdTabBlock.
- Your settings, such as whether to show the on-page notice.
- Counters of how many ad tabs were blocked, per site and in total, and the address of the last blocked tab for each site, so you can press "Allow once".
This information never leaves your browser. You can clear it any time with "Reset stats" in Settings, or by removing the extension.
What the extension does not do
- No analytics, tracking pixels or usage statistics.
- No accounts and no sign-in.
- No sending of your browsing history, page content or personal information to us or anyone else.
- No remote code. Everything the extension runs is inside the package you install.
- No selling or sharing of data, and no use of data for advertising or credit decisions.
Why it needs its permissions
- Access to the sites you visit: to stop ad tabs, AdTabBlock has to run on the pages where they happen. It looks only at how a page tries to open new tabs. It does not read or save what you type or read.
- Web navigation: to notice when a page opens a new tab, so an ad tab can be closed.
- Storage: to remember your settings and counters on your computer.
When you uninstall
When you remove the extension, Chrome opens adtabblock.com/bye with the extension's version number in the address. Answering the short question there is optional.
