Where it's AT collects no personal data. It collects no data of any kind.

Nothing is sent to the developer or to any third party. No analytics, no telemetry, no logging, no accounts.

The extension only reads the page you are looking at locally in your browser, to find the atproto references (at://… URIs and related RDFa attributes) that are displayed. Your chosen click action is stored in your browser via chrome.storage.sync so it can sync across your own signed-in browsers; only you have access to this.

The extension makes no network requests on its own. The only outbound requests it can cause are the ones you explicitly trigger by clicking a highlighted reference or selecting "Visit" from the right-click menu — which opens the AT URI explorer you've configured (PDSls, Tapestry, or a custom URL you provide) in a new tab, exactly as if you had clicked a link yourself.
