01 What the extension does

TabNest saves and organizes your browser bookmarks with live website previews displayed in a visual grid. It stores your bookmarks and folders locally in your browser and renders live iframe previews of saved pages.

02 Data we store

All data remains on your device and is never transmitted to external servers.

03 Data we do not collect or sell

04 Permissions and why they are needed

05 How iframe previews work

When you view your bookmarks, TabNest renders live iframe previews of each saved page directly inside the extension's tab. The header-removal rules run locally in your browser to allow pages to be framed. No page content passes through any server controlled by TabNest.

06 Ad network content

TabNest may display ads from third-party ad networks (e.g. Google AdSense, Media.net). These ad providers may set their own cookies or collect data in accordance with their own privacy policies. TabNest does not control or have access to data collected by ad providers.

07 Data retention and control
