App: Drag Race & 0-60 Performance Timer (the “App”)
Developer: Rui Pedro Correia
Contact: rpcalpetra@gmail.com
Effective date: June 19, 2026  ·  Last updated: June 19, 2026

This Privacy Policy explains what information the App collects, how it is used, and with whom it is shared. By using the App you agree to the practices described here. If you do not agree, please do not use the App.

The App does not require you to create an account, and it does not ask you for your name, email, or other directly identifying personal information.


1. Information we collect

a) Information you provide

The App lets you optionally enter vehicle details (such as vehicle type, weight, power, and drivetrain) and notes about your runs. This information is stored locally on your device and is used only to calculate and display your performance metrics. It is not transmitted to the developer.

b) Location data

The App uses your device's precise location (GPS) to measure speed, distance, split times, and route information, which are the App's core features. Location is processed on your device and stored locally as part of your run data.

When you record a run, the App may send the coordinates of that run to a third-party weather service (OpenWeatherMap) to retrieve the weather conditions at that location, so it can show and correct your results for conditions. See Section 3.

c) Motion and environment sensors

The App reads device sensors (such as the accelerometer and, where available, the barometer) to estimate acceleration, G-force, lean angle, and altitude. This sensor data is processed on your device and stored locally with your run data.

d) Usage and diagnostic data

Through the third-party services listed in Section 3, the App automatically collects:

This data is used in aggregate to understand how the App is used and to fix problems. The App does not collect data to build advertising profiles, and it does not contain advertising.

e) Purchases

When you subscribe to the premium version, your purchase is processed by Google Play and managed through RevenueCat. The App receives your subscription status (active / not active) but never receives or stores your payment card details.

2. How we use information

We use the information described above to:

Relevant third-party policies:

4. Data storage and retention

Your run history, vehicle profile, records, and preferences are stored locally on your device. The developer does not operate a server that stores your runs.

Uninstalling the App removes the data stored on your device. Data held by the third-party services above is retained according to their own policies; analytics and crash data are retained for a limited period for the purposes described above.

5. Your rights

Depending on your location, you may have rights under laws such as the GDPR (EU/EEA) or CCPA (California), including the right to access, correct, or delete your data, and to object to or restrict certain processing.

6. Children's privacy

The App is not directed to children under the age of 13 (or the equivalent minimum age in your jurisdiction), and we do not knowingly collect personal data from children. If you believe a child has provided us with data, please contact us.

7. Security

We rely on the security measures of the operating system and the reputable third-party providers listed above. No method of transmission or storage is completely secure, but we take reasonable measures to protect your information.

8. Changes to this Policy

We may update this Privacy Policy from time to time. The “Last updated” date at the top reflects the latest version. Continued use of the App after changes become effective constitutes acceptance of the updated Policy.
