First of all, thank you for choosing Wit!
Alfredo Jimenez built the Wit app as a Free app. This SERVICE is provided at no cost and is intended for use as is.
Here you will find all the information regarding your privacy while using Wit App.
In Short - Wit App does not collect personal data on its servers. However, certain data such as heart rate may be processed locally on the user’s device when using compatible Wear OS features.
In addition, the app uses third-party services described below:
Google Play Services: As you may have downloaded Wit App through Google Play, you accepted Google's privacy policy, if you are worried about this, visit this link.
Firebase (Authentication and Firestore Database): To enable the workout sharing feature, the app uses Firebase Authentication with anonymous sessions and Firebase Firestore Database.
The processing of the information described below is carried out under the legal basis of Contractual Necessity (Art. 6(1)(b) of the GDPR), as its use is strictly necessary to provide the storage and sharing service requested by the user.
Firebase Authentication creates a temporary technical identifier (UID). This identifier does not contain direct identifying information (such as name or email) and is used solely and strictly to make the requested workout sharing functionality possible. The UID is automatically deleted from the backend systems after 30 days.
Firestore Database stores the content of the workout you share (for example: “do push-ups for 30 seconds”), along with the date it was shared and the date it was last accessed. These records do not contain personal information and is not intended to identify users. All data is automatically deleted 10 days after its last access, through an automated process implemented within the app’s backend.
Health Data (Wear OS)
Heart rate data is considered health data under applicable data protection laws. If the user explicitly grants permission, the app accesses heart rate data during workout sessions.
Foreground Service & Background Access: To ensure your workout and heart rate tracking are not interrupted when the watch screen turns off or when you switch apps, Wit uses a Foreground Service (HEALTH) and Background Sensor access. This is strictly necessary to provide continuous monitoring and accurate timing during high-intensity training sessions.
Local Storage (Room): This data is processed and stored locally on the user’s device using a Room database to display statistics and graphs. It is not transmitted to the developer’s servers or any external third parties. The app does not have a "cloud sync" for health data; therefore, the developer cannot access, manage, or see your heart rate information.
Activity Recognition permission is used to automatically detect exercise status and optimize stopwatch accuracy.
This data is not used for profiling, advertising, or analytics purposes.
Legal basis for health data processing
The processing of heart rate data is based on the user’s explicit consent (Art. 9(2)(a) GDPR), which is requested through the device’s permission system. The user can revoke this permission at any time from the device settings.
This application complies with the Health Connect User Data Policy, including the Limited Use requirements.
Data storage and deletion
All health-related data is stored locally on the user’s device. You have full control over this data: you can delete all locally stored heart rate and workout records at any time by clearing the app’s cache/data in your device settings or by uninstalling the application.
The app does not control Android’s automatic backup systems, which may include this local database depending on your Google account configuration.
