Where Your Data Goes

Nowhere. All calculations happen entirely on your device. Your financial data never leaves your phone. We don't have servers to store it, and we don't have any way to access it.

Third-Party Services

We don't use any third-party analytics, advertising, or tracking services. No Google Analytics, no Facebook SDK, no advertising networks, no crash reporting services with user data. Zero third parties have access to your information because we don't collect any.

Permissions

DieselCalcs doesn't request any device permissions. No access to your camera, photos, contacts, location, or anything else. It's just a calculator.

Data Security

Since we don't collect or transmit any data, there's no data to secure or breach. Your calculations stay on your device, protected by your device's own security measures.

Children's Privacy

DieselCalcs doesn't collect any information from anyone, including children under 13. The app is safe for all ages.

Changes to This Policy

If we ever change our privacy practices (spoiler: we won't), we'll update this page and the app. But our commitment to zero data collection is permanent.
