Privacy policy

Ruhsat is a car maintenance and fuel tracking app. This policy explains which information the app keeps, where it is stored, who it is shared with and how you can delete it. Effective date: 5 November 2026.

Using the app without an account

If you use the app without an account, your cars, fuel and expense entries, reminders and settings stay only on your phone, in the app's own database. Nothing is sent to a server. If you delete the app or change phones, these entries are lost.

Using the app with an account

If you sign in with your email, your email address and your entries (cars, fuel and expense entries, reminders) are stored with Supabase on a server in the European Union (Frankfurt) so they can be synced between your phones and backed up. There is no password; a 6-digit code is sent to your email to sign in. The code is delivered through the Resend email service, which processes your email address only to deliver it.

Each user can only see and change their own entries; this rule is enforced in the server's database. Entering a licence plate is optional.

The app shows a single Google AdMob banner on the Stats and History screens. Ads are not personalized: no advertising identifier is used to track you across apps and websites, so the app does not ask for tracking permission. Google may process device and connection information (such as device type and approximate location derived from your IP address) to serve and measure the ad and to prevent fraud. Users in the European Economic Area are asked for consent through Google's consent form; you can change your choice in Settings > Ads > Ad privacy options.

Your car entries are never used for advertising and are never shared with Google.

Remove ads purchase

The payment to remove ads is handled by Apple's App Store. Your payment details stay with Apple and never reach us. The purchase belongs to your Apple ID; the app only learns from Apple whether the purchase exists.

Notifications and widget

Inspection, insurance, road tax and service reminders are scheduled on your phone; no server is used for them. The home screen widget reads its summary from the app on your phone.

Export

When you export your fuel and expense entries as a CSV file, the file is only shared to the place you choose (for example Files or email).

Deletion

Settings > Account > Delete account immediately deletes your account and all your entries on the server, and removes the copy on your phone. Settings > My data > Delete all data deletes your entries from your phone (and from your account if you have one). Entries marked as deleted in the app are fully removed from the server within 30 days.

Children

The app is not directed at children under 13 and does not knowingly collect information from them.
