DriveCost – Privacy Policy

Last updated: October 31, 2026

DriveCost (“the app”) is developed by Stipe Grbić. This policy explains what data the app collects and how it is used.

Data storage
All car and expense data you enter is stored locally on your device using SQLite. Photos you add are stored on your device only. Your data does not leave your device except as described below (AI Insights, usage statistics) or when you use the PDF export feature to share it.

AI Insights
When you use the AI Insights feature, a summary of your data is sent to our server (Google Firebase Cloud Functions) and passed to Anthropic’s Claude API to generate insights. The summary includes your car’s year, make, model, fuel type and mileage, monthly cost totals, a cost breakdown by category, average cost per kilometre and average fuel consumption. It does not include notes, licence plates, photos or individual entries. Your data is not stored on our server; to prevent abuse, the server keeps a daily usage count tied to a random anonymous ID (Firebase Anonymous Authentication), and requests are verified with Firebase App Check. Anthropic processes the data under its commercial terms and does not use it to train its models; see anthropic.com/legal/privacy.

Usage statistics (Google Analytics for Firebase)
The app uses Google Analytics for Firebase to understand which features are used, so we can improve the app. It records which screens you open and when you add a car or an entry, including the fuel type, expense or service category, amount, litres, and whether a photo was attached. It never includes your car’s make, model or licence plate, your notes, or your photos. Google Analytics also collects standard technical information such as device model, operating system, app version, approximate region, and a random app instance identifier. The app does not collect your advertising identifier and is not used for advertising.

You can turn this off at any time in Settings → Share usage statistics. Google’s privacy policy applies: policies.google.com/privacy.

In-App Purchases
Subscription management is handled entirely by Apple through the App Store. The developer does not have access to payment details.

Feedback
If you use the Send Feedback option, your email client will open a pre-addressed email. Any information you choose to include is sent directly to stipegrbic@hotmail.com and is not processed or stored automatically.

Your rights
Depending on where you live, you may have the right to access, delete or object to the processing of your data. Your car data is on your device and can be deleted in the app or by uninstalling it. For anything else, contact us below.
