Privacy Policy
Last updated: May 21, 2026
1. Data Controller
The data controller for personal data collected through the TankoUp mobile application and website is:
- Name: TankoUp
- Contact email: tanko.up.app@gmail.com
For any questions about how we handle your personal data, please contact us at the email address above.
This policy is accessible from the app settings menu and the website footer.
2. Data We Collect
TankoUp does not require registration or account creation. We do not collect your name, email address, or any other identifying information voluntarily.
The following data is collected automatically:
2.1 GPS Location
When you grant location permission on your device, we collect your precise geographic position only during the active session in order to show you nearby gas stations. This data is not stored on our servers and is not linked to any user profile.
2.2 Usage Data (Analytics)
Through Firebase Analytics (Google LLC), we collect anonymous information about how the app is used: screens visited, searches made, and general interactions. This data is aggregated and cannot identify you individually.
Firebase Analytics may collect the device advertising identifier (IDFA on iOS, GAID on Android) for analytics purposes. On iOS, this access requires prior user consent through the App Tracking Transparency (ATT) prompt; if you do not grant consent, the IDFA is not accessed.
2.3 Crash and Performance Data
Through Firebase Crashlytics (Google LLC), we automatically collect crash reports (stack traces) and basic device information when the app closes unexpectedly. This helps us detect and fix technical errors.
