# Privacy Policy

**App name**: FitStrike
**Last updated**: May 14, 2026

## 1. Introduction

FitStrike (the "App") respects your privacy. This Privacy Policy explains what information the App handles and how. By installing and using the App, you agree to this Policy.

## 2. Information We Store

The App stores the following information **only on your device**. **Nothing is ever sent to any external server.**

- Session history (date and time, score, hit count, block count, damage count, workout duration, estimated calories burned)
- User settings (weight, calorie goal, reminder on/off, reminder time, BGM/SFX volume, language, onboarding completion status)
- Streak records (current streak, best streak, last session date)

All of this data is removed completely when you uninstall the App. You can also clear session history and streaks at any time from "Delete all data" in the App's settings screen.

## 3. Camera Use

The App uses your phone's front camera to detect punching motion.

- Camera frames are **processed entirely on-device** and are never stored or transmitted
- Pose estimation runs locally with Google ML Kit (on-device, no network calls)
- Camera access is requested only with your explicit consent
- You can revoke camera permission at any time from your device's settings

## 4. Weight / Body Information

You can **optionally** enter your weight for calorie estimation. This information:

- Is stored only on your device and never transmitted
- Is used only to estimate calories burned (calories = weight × time × intensity)
- Can be deleted or changed at any time from the settings screen

All workout features work without entering your weight (calories will simply display as "-").

## 5. Notifications

If you enable the "Reminder" feature, the App will send local notifications at the time you set.

- Notifications are scheduled locally on your device; no external server is involved
- You can change or disable notifications at any time from the App's settings or your device's notification settings

## 6. Third-Party Libraries

The App uses the following open-source libraries / SDKs:

- Flutter SDK (Google LLC)
- Google ML Kit Pose Detection (on-device processing; frames and inference results are never transmitted)
- audioplayers / sqflite / shared_preferences / flutter_local_notifications / table_calendar and other public packages from the Flutter ecosystem

These are integrated for the App's functionality. The App does not transmit any user data on its own.

## 7. Advertising and Analytics

The App currently does not include any advertising or behavioral analytics. If we introduce these in the future, we will update this Policy and notify users in advance.

## 8. Children's Privacy

The App can be used at any age, but if a child under 13 uses the App, please ensure it is with parental consent and supervision.

## 9. Changes to this Policy

This Policy may change without prior notice. We will announce significant changes inside the App or in the store description.
