attention awareness

Browser extension privacy

The attention awareness extension hides feeds with CSS. It collects nothing.

What it stores

Your switches (on or off per site) and the custom CSS rules you write, in the browser's extension storage.

If you are signed into your browser, the browser may sync that storage across your devices. Nothing else.

What it sends

Nothing. No analytics, no crash reports, no remote code, no network requests of its own.

What it can see

The pages on x.com, youtube.com, instagram.com and tiktok.com, only to inject CSS.

If you add a custom rule for another site, the browser asks you once for access to that site. The extension then injects your CSS there and nothing more.

Open source

The code is public at github.com/mertbuilds/attentionawareness, and the rules are plain CSS files you can read.
