This extension collects no data. Nothing is transmitted anywhere, so there is nothing to sell, share, or hand over. This is declared in the manifest as data_collection_permissions: { required: ["none"] }, which Firefox shows in the install prompt.

The PDF you act on is read using your own browser session and held in the browser's own storage only for the seconds it takes to reach the OxygenPDF tab, then deleted. Anything a handover leaves behind is cleared within ten minutes by an alarm. No PDF, and no address, is ever sent to us or to any third party — the extension makes no network request to our servers at any point.

The only thing stored beyond a handover is the list of tools you pin in the popup, kept on your own machine, not synced, and removed with the extension.
