Awl, On Us has no database and no user accounts. Here’s exactly what happens with your data.
When you tap to share your location, your browser’s built-in geolocation API asks you for permission and hands your coordinates to the app running in your browser. Those coordinates are sent to this app’s own server, which forwards them to the Overpass API, OpenStreetMap’s public query service, purely to fetch places near you and return them to your browser. Your coordinates pass through that request but are not written to a database or logged anywhere — this app doesn’t keep one. If you deny location access, you can drop a pin on the map instead, which works the same way.
The only thing this app remembers is a display preference: whether you like distances shown in miles or kilometers. That’s saved in your browser’s local storage, on your device only, and is never sent anywhere.
There’s no signup, no login, and no analytics or tracking scripts collecting your activity. Restaurant listings themselves come from OpenStreetMap — see the About page for more on that.
