Prices come from official data published by the Régie de l'énergie du Québec, which sets the legal minimum price floor for every gas station in the province. The app fetches this data directly from the Régie's servers.
Data is refreshed every time you open the app. In the background, the app also periodically checks for new updates from the Régie so it can alert you when prices change at your favourite stations.
Add a station to your favourites (⭐ icon in its detail sheet), then enable alerts for that station (🔔 icon). The app monitors prices in the background and sends you a local notification as soon as a change is detected — without ever sending your data to an external server.
Yes. Every gas station registered with the Régie de l'énergie du Québec appears on the map, regardless of region.

Tap a station to open its detail sheet, then select the History tab. You'll see how prices have changed over time, with the ability to navigate through past periods.
No. The app does not collect or transmit any personal data. Your GPS location, favourite stations, and preferences stay on your device only. Firebase Crashlytics is the sole third-party service used, for crash reporting. See our Privacy Policy for full details.
