Attribute Viewer Sidebar does not collect, store, transmit, or share any personal data, browsing history, or user information of any kind.

The extension operates entirely locally within your browser. When activated via the toolbar button, it reads publicly visible HTML attributes on the current page — such as image alt text, link target attributes, and tel:/mailto: link values — and displays this information in a floating panel for your reference. This data is read directly from the page's DOM in your browser and is never sent to any external server, third party, or the developer.

The extension does not use cookies, analytics, tracking scripts, or any remote services. It does not require an internet connection to function and makes no network requests.
Since no data is collected, none is retained, sold, or shared.

If you have questions about this policy, please contact the developer via the extension's listing page.
