# Privacy Policy for KindEars

**Last updated: February 08, 2026**

## Overview

KindEars is an audio application for Android that includes a music player, MIDI player, internet radio, and audio editor. This Privacy Policy explains how KindEars handles your data.

**In short: KindEars does not collect, store, or transmit any personal data to external servers. All your data stays on your device and optionally on your personal Google Drive account.**

## Data Collection

### What We DO NOT Collect

- No personal information (name, email, phone number)

- No usage analytics or tracking

- No advertising identifiers

- No location data

- No device identifiers sent to external servers

- No crash reports sent to external services

### What Stays On Your Device

KindEars stores the following data **locally on your device only**:

- **Music library metadata**: Artist, album, track information scanned from your audio files

- **Playlists and favorites**: Your custom playlists and favorite tracks

- **Play counts**: How many times you've played each track

- **App settings**: Your preferences (theme, synthesizer settings, etc.)

- **Radio recordings**: Audio files you record from internet radio streams (saved to your device's Music folder)

- **SoundFont projects**: Your custom SoundFont creations (stored locally on your device)

This data is stored in local databases and files on your device. It is never transmitted to any external server.

## Google Drive Sync (Optional Feature)

KindEars offers an **optional** Google Drive synchronization feature to backup and sync your favorites and playlists across devices.

### How It Works

- Uses Google Sign-In with OAuth 2.0

- Stores data in your **private app folder** on Google Drive (`appDataFolder` scope)

- Only KindEars can access this folder - it's hidden from your regular Drive files

- No other apps or services can read this data

### What Is Synced

- Favorite tracks list

- Playlist data

- Play counts

### What Is NOT Synced

- Your actual audio/MIDI files — you need to have these files on each device 

- Radio recordings

- App settings

### Your Control

- You can enable or disable sync at any time in the app settings

- You can delete your cloud data using the "Delete cloud data" option in the app

- You can revoke access via your [Google Account permissions](https://myaccount.google.com/permissions)

- Deleting the app removes local data; use the in-app option to delete cloud data before uninstalling

---

## Internet Radio

When using the internet radio feature:

- KindEars connects directly to radio station streams you select

- Station searches use the public [Radio Browser API](https://www.radio-browser.info/)

- No personal data is sent to radio stations or the Radio Browser API

- Radio recordings are stored locally on your device

---

## Lyrics Feature

The lyrics feature allows you to configure your own API:

- **You** provide your own API key and endpoint

- KindEars only acts as a client to display the results

- We do not provide, manage, or control any lyrics API service

- You are responsible for complying with the terms of service of any API you choose to use

- Song title and artist name are sent to the API endpoint you configure

**Note:** KindEars is not responsible for the privacy practices of third-party lyrics APIs you choose to use.
