OneBNB stores everything it knows (hidden listings, stars, maybes, notes, ordering) in your browser's local extension storage. Nothing is sent to the developer. The extension has no server, no analytics, no accounts, and collects no personal data. It reads airbnb.com pages and Airbnb's own search responses solely to display prices and your saved state on your screen.

One feature talks to a third party: when you type an address into the panel's search box, that text (plus the current map position, so nearby results rank first) is sent to Google's map search to find the place, without cookies and not tied to any account. Nothing is sent anywhere unless you type in that box.

Removing the extension deletes its data.
