Privacy

Gastione has no accounts. We never ask for your name, email or phone number.

What the app uses on your phone

• Location, only while the app is open: to find stations near you and to check that you are at the station when you report a price. To search, the app downloads the station list and searches it on your phone: your search location is not sent to our server.
• Camera, only to take the photo of the price sign inside the app. The app cannot upload photos from your gallery.
• Notifications, to tell you when a nearby station drops its price while the app is open.

Your settings, the prices saved for offline use and any reports not yet sent stay on the phone. They are deleted when you uninstall the app.

What we keep on our server

• An anonymous identifier for your install. We keep only a hash of it, plus a short number you can see in Settings (for example, #00042). If the app is not used for 180 days, it is deleted.
• Your reports: the station, fuel, price, time and the exact location you reported from, which we use to review the report. After 30 days we delete that location and the link between the report and your install. The price, station and time stay, with no way to tell who sent them.
• The photo of the sign: we strip its hidden data (such as GPS and phone model), use it to read the price, and never show it to other users. It is deleted after 30 days. We keep a fingerprint of the photo to spot reused photos; the photo cannot be rebuilt from it.
• A security log of rejected or held reports: the install number, the station and a fragment of a hash of your network. We do not store your IP address. This log is also deleted after 30 days.

Who else sees anything

• Cloudflare carries the traffic between the app and our server, so it sees your IP address, like any network a connection passes through.
• Mapbox draws the map in the app and receives the map areas you look at, like any map app.
• For live prices, the app listens to the towns you are looking at. Our message server sees those towns, not your location.
• Today we read photos on our own server. If we ever use an outside service to read them (such as Google Cloud Vision), we will say so here first.

We do not sell or share data with advertisers. The app has no ads.

This website

This site uses no cookies or analytics and serves its own fonts. Its pages ask our own server for the latest app version and any announcement; like any request, that shows your IP address to our server and to Cloudflare, and we do not store it. The download button goes through our server, which counts one download (only the version and the day, never an address or a device, and once per network per hour) and then sends you, with a link that lasts a few minutes, to the file in our private storage at Cloudflare, which sees your request as any website would. The live map connects to Mapbox, which draws it and receives the areas you look at. If you tap "My location", your browser uses it only to center the map; it is not sent to our server.

Erasing your data

To have everything tied to your install erased, write to [email protected] with the number shown in Settings (for example, #00042). You can also uninstall the app: what is left on the server deletes itself on the schedule above.

Children

Gastione is not directed at children under 13 and does not knowingly collect data from them.
