Privacy Policy

1. Introduction

Welcome to HappyTooth ("we," "our," or "us"). We are committed to protecting your privacy and ensuring you have a positive experience when using our mobile application and website.

This Privacy Policy explains:

• What information the app accesses on your device
• How that information is used
• Your rights regarding your data
• How we comply with privacy regulations

2. Information We Access

2.1 Bluetooth Device Information

The app accesses the following information to provide Bluetooth management functionality:

• Bluetooth Device Names: Names of paired and nearby Bluetooth devices
• MAC Addresses: Hardware addresses of Bluetooth devices for connection management
• Connection Status: Whether devices are connected, disconnected, or available
• Device Types: Audio profiles (A2DP, HFP, LE Audio)
• Pairing Status: Which devices are paired with your phone

Storage: This information is stored locally on your device only and is never transmitted to external servers.

2.2 Location Information (Optional)

Location permissions are requested for the following purposes:

• Bluetooth Scanning (Android Requirement): Android requires location permission to scan for nearby Bluetooth devices due to the possibility of inferring location from Bluetooth beacons
• Location-Based Automation (Future Feature): If enabled, location data may be used to automatically switch profiles based on your location

Important: Location data is processed entirely on your device and is never sent to our servers or any third party. You can use HappyTooth without granting location permission, but Bluetooth scanning functionality will be limited.

2.3 App Configuration Data

The following information is stored locally on your device:

• Profile names and icons you create
• Device assignments to profiles
• Device roles (Primary, Optional, Fallback)
• App settings and preferences

2.4 Technical Information

For app functionality and crash reporting (if enabled):

3. How We Use Information

All information accessed by HappyTooth is used solely for the following purposes:

• Bluetooth Management: Connect, disconnect, and manage your Bluetooth devices
• Profile Switching: Enable quick switching between different device configurations
