Privacy policy

Fuelza · Last updated 30 August 2026

Fuelza has no accounts and no sign-up. We collect as little as the app needs to work, we never sell data, and we do not use any of it for advertising or tracking.

Location

When you allow location access, the app sends your coordinates (or the route you chose) to our server to find gas stations around that point. The request carries no name, e-mail, phone number or advertising identifier. Coordinates are not stored beyond ordinary short-lived server logs. CarPlay may ask for background ("Always") access so the car screen can show nearby stations when the phone is locked; refusing it does not limit the phone app.

Your settings

Fuel type, consumption, loyalty cards, custom discounts and favourite stations are stored only on your device (and in your iCloud device backup). They are never uploaded.

Messages you send us

If you use Settings → Send us a message, we store the text you wrote, the e-mail address if you chose to give one, and technical details that help us reproduce problems (app version, iOS version, device model, language). We use them only to answer you and improve the app, and delete them once handled or after 12 months.

Diagnostics and usage (Firebase)

The app uses Google Firebase Crashlytics (crash reports) and Analytics (anonymous usage counts such as which screens are opened), configured without the advertising identifier. Firebase generates a random installation identifier for this purpose; it is not linked to you, not shared with advertisers and not used for tracking across apps. Google processes this data on our behalf under the Firebase privacy terms. Crash and usage data are retained by Firebase for up to 90 days (crash reports) and 14 months (analytics).

What we do not do

• No accounts, no e-mail lists, no passwords.
• No advertising, no advertising identifiers, no tracking across apps or websites.
• No selling or sharing of data with data brokers.

Your rights

Under the GDPR you can ask what we hold about you and have it deleted. Because there are no accounts, the only data we could hold is a message you sent us — write to gsaenz@proatomicdev.com and we will remove it. Deleting the app removes all on-device settings.
