StallCall ("the app") helps you find nearby public restrooms. This page explains what data the app uses, why, and how it's handled. We built StallCall to work with as little personal data as possible.
StallCall asks for your location (only "while using the app") to show restrooms near you and calculate walking distance and time. Your coordinates are sent to the public map/restroom data services the app queries — OpenStreetMap (Overpass API), Refuge Restrooms, Apple Maps (MapKit), and select official city open-data feeds — solely to look up nearby results. StallCall does not operate its own server that logs or stores your location history; your location is used live, for each search, and is not retained beyond that.
If you choose to sign in, StallCall uses Sign in with Apple. The identifier, name, and/or email Apple provides are stored only on your own device, to keep your saved stalls, badges, and confirmations tied to your profile. This information is not transmitted to or stored on any StallCall server, because StallCall does not currently operate one.
Favorites, confirmations, badges, and any restrooms you add through "Add a stall" are stored locally on your device (in iOS's standard app storage). They are not currently uploaded to or shared through any StallCall server.
Because StallCall pulls restroom data from OpenStreetMap, Refuge Restrooms, Apple Maps, and city open-data portals, your search coordinates are sent to those services to retrieve results, subject to their own privacy practices. We don't control how these third parties handle that data beyond the request itself.
If StallCall's data practices change — for example, if we introduce an optional shared leaderboard backed by our own server — this page will be updated first, and the update will describe exactly what's new.
