Thank you for using Muscle Booster ("the App"). Your privacy is important to us. This Privacy Policy explains what information the App may collect, how it is used, how it is stored, and the choices available to you.
Depending on how you use Muscle Booster, the App may handle the following types of information.
The App may generate basic usage information required for its functionality, such as workout completion status, training statistics, streaks, milestones, and app settings.
Information handled by the App may be used to:
We do not use your fitness information for automated medical diagnosis or treatment.
Muscle Booster may allow you to enter fitness-related information, including body weight, height, workout history, exercise performance, and fitness goals.
This information is used to provide fitness tracking and workout features within the App. The App does not provide medical diagnosis, treatment, or professional healthcare services.
Workout records, preferences, progress information, and other data may be stored locally on your device using local application storage.
If a particular version of the App provides cloud synchronization, backup, or other online services, the applicable data practices will be disclosed within the App and this Privacy Policy will be updated accordingly.
We do not sell, rent, or trade your personal information.
Information may only be disclosed when reasonably necessary:
Depending on the version and configuration of the App, Muscle Booster may use trusted third-party services such as Google Play Services, Firebase Analytics, Firebase Crashlytics, or other technical services.
If third-party services are enabled, they may process limited technical information according to their own privacy policies.
If advertisements are included in the App, third-party advertising providers may collect information required to display and measure advertisements in accordance with their respective policies.
If the App does not contain advertising, no advertising information is collected through the App.
Muscle Booster requests permissions only when they are required for specific features.
Notification permission may be used to send workout reminders, training notifications, or other user-requested alerts.
If additional permissions are introduced, they will be requested only when necessary for the corresponding feature and will be explained to the user where appropriate.
We use reasonable technical measures to help protect information handled by the App from unauthorized access, alteration, disclosure, or destruction.
However, no electronic storage method or transmission method can be guaranteed to be completely secure.
Data stored locally by the App generally remains on your device until you delete it, clear the App's data, or uninstall the App.
If online data storage or account-based services are introduced, appropriate deletion mechanisms and instructions will be provided.
Muscle Booster is intended for general fitness use and is not specifically directed toward children.
We do not knowingly collect personal information from children in violation of applicable laws. If you believe that a child has provided personal information through the App, please contact us.
Depending on applicable laws, you may have rights regarding your personal information, including:
Since much of the App's fitness data may be stored locally, you can generally remove it by clearing the App's data or uninstalling the App.
We may update this Privacy Policy from time to time to reflect changes to the App, technology, legal requirements, or our data practices.
Any updated version will be published on this page with a revised Effective Date.
Muscle Booster is intended for general fitness, exercise planning, and educational purposes only.
Workout recommendations, calculations, progress statistics, and other information provided by the App should not be considered medical advice or a substitute for professional healthcare advice.
Consult a qualified healthcare professional before beginning a new exercise program if you have a medical condition, injury, or other health concern.
