Privacy Policy
Last updated: September 26, 2026
1. Purpose
BadShadow is an app designed for badminton shadow training. This policy explains what data may be used by the app, why it is used and how it is protected.
2. Data used by BadShadow
Depending on the features enabled, BadShadow may use:
- Apple Watch motion data to detect strokes;
- heart rate data, only when the user grants permission;
- training session data such as duration, exercises, detected strokes, statistics and history;
- technical information required for communication between iPhone, iPad and Apple Watch.
3. Apple Health / HealthKit
When Apple Watch is used, BadShadow may save a Badminton workout to Apple Health / HealthKit. Access to Health data is controlled by Apple permissions.
Users can change or revoke these permissions at any time from the Health and Privacy settings on their Apple devices.
4. Storage and transfer
BadShadow data is stored locally on the user’s devices. Information required for operation between Apple Watch, iPhone and iPad is transferred directly between those devices.
BadShadow does not use user accounts, remote servers to store training sessions, advertising, third-party analytics tools, or telemetry automatically sent to the developer.
5. Sharing with third parties
BadShadow does not sell users’ personal data. Health, motion and training data is not shared with advertisers, data brokers or marketing services.
6. Diagnostic files
BadShadow can generate a diagnostic file to help identify technical issues. This file is sent to the developer only if the user explicitly chooses to share it. No diagnostic data is sent automatically.
7. Retention and deletion
Locally stored data remains on the device until it is deleted by the user or until the application is removed, depending on the type of data.
Data saved in Apple Health is managed separately by Apple Health and can be deleted from the Health app.
8. Changes to this policy
This policy may be updated if BadShadow features change. The “Last updated” date shown on this page will be revised accordingly.
