Privacy Policy for BetterLyrics

Effective Date: June 3, 2025

Welcome to BetterLyrics ("we", "us", "our"), an application developed by Zhe Fang. We are committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our BetterLyrics application (the "App").

This App is a desktop application. Your data is primarily stored locally on your device.

1. Information We Process

BetterLyrics is designed to minimize data collection. We do not require you to create an account, and we do not collect personal identification information (PII) such as your name, address, or phone number.

To provide its core services, the App may process the following types of information:

a) Information You Provide

Apple Music Token: If you choose to use the Apple Music lyric source, the App requires you to provide a self-generated token. This token is stored only on your local device and is used solely to make requests to the Apple Music API on your behalf to fetch lyrics. We do not upload or collect this token.
Local Settings: All your preferences and settings are stored locally on your device.

b) Information Processed for Functionality

Song Metadata: To fetch lyrics, the App must send song metadata (such as the song title, artist, and album) to the third-party lyric provider you have selected. This information is sent anonymously and is not linked by us to your personal identity.
Log Files: The App automatically collects and stores log files on your local device for debugging and troubleshooting purposes. These logs only contain necessary debug information and are not automatically uploaded to us. We may ask you to manually provide these logs if you require technical support.
Analytics: We do not collect any anonymous usage statistics or analytics about how you use the App.
Update Checks: The App does not automatically check for new versions.

2. How We Use Information

We use the information processed solely for the following purposes:

To provide and maintain the App's core functionality (i.e., fetching and displaying lyrics based on song metadata).
To store your configuration and credentials (like the Apple Music Token) locally, so you do not have to re-enter them.
To help diagnose and fix bugs via local log files (only when you manually provide them).

3. Third-Party Services

BetterLyrics' core functionality relies on interacting with third-party lyric providers. These services include, but are not limited to:

NetEase Cloud Music (网易云音乐)
QQ Music (QQ音乐)
Kugou Music (酷狗音乐)
Apple Music (requires your own token)
amll-ttml-db (GitHub open-source lyric database)
LRCLIB

When you request lyrics via the App, your song metadata is sent to these services. These third parties have their own privacy policies governing their use of data. We are not responsible for the data practices of these services. We recommend you review their respective privacy policies.

We do not sell, trade, or rent any of your information.

As described, your sensitive information (like the Apple Music Token and logs) is stored locally only by default. We do not automatically access or share this information.

The only exception is when you initiate a lyric request, at which point song metadata is sent to the third-party service you selected, as described in Section 3.

5. Data Security

We take reasonable measures to protect the information processed by the App. We specifically emphasize:

Apple Music Token: This sensitive credential is stored only on your local device. You are responsible for protecting the security of your device. If you suspect your token is compromised, please revoke it immediately via Apple Music and generate a new one.
Local Logs: Log files are also stored locally.

As your data is primarily stored on your device, the security of that data is dependent on the security of your own device.

6. Children's Privacy

The App is not intended for use by children under the age of 16. We do not knowingly collect any information from children under 16.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy in the App or on our GitHub repository.
