Privacy Policy

Last updated: March 29, 2026

Welcome to Music Switch. We recognize that your music library is more than just a list of songs; it is a curated collection of memories, emotions, and personal preferences. At Music Switch, we are committed to maintaining the trust you place in us when you use our playlist transfer service. This comprehensive Privacy Policy describes our practices regarding the collection, use, and safeguarding of your information when you interact with our website (musicswitch.app) and our transfer synchronization tools.

Our mission is to provide a seamless bridge between platforms like Apple Music, YouTube Music, NetEase, and QQ Music without ever compromising your digital footprint. By using Music Switch, you agree to the terms outlined in this policy.

๐Ÿ”’ Privacy First Promise

Our "Privacy First" philosophy is built into the very architecture of our code. Unlike traditional cloud-sync services that may attempt to profile your listening habits for advertising, Music Switch operates as a "pass-through" utility. We do not store your music library data on our permanent databases. All matching and transfers happen in real-time, and your temporary session data is purged immediately after the transfer lifecycle is complete.

Our Core Privacy Principles

To ensure the highest standard of data protection, we adhere to four foundational pillars:

Zero Permanent Data Storage

Your playlist names, track listings, and artist preferences are processed in volatile memory. This means once the transfer "handshake" between your source (e.g., Apple Music) and destination (e.g., NetEase) is finished, the data vanishes from our processing unit.

Radical Transparency

We believe you should never be in the dark. Our interface displays exactly what data is being read and written at every stage of the 4-step transfer process, ensuring you maintain 100% oversight.

Encapsulated Temporary Sessions

To provide a stable user experience and allow for "retry" logic if a connection drops, we maintain a temporary session state. However, these session logs are automatically hard-deleted after 24 hours of inactivity.

User Sovereignty

You are the sole owner of your music accounts. Music Switch never asks for or stores your passwords. We use industry-standard delegated authorization, giving you the power to revoke our access at any moment through your platform's security settings.

Information We Collect and How We Collect It

When you connect a music platform, such as YouTube Music or QQ Music, we utilize the OAuth 2.0 protocol. This is the gold standard for security because it allows us to request a specific "token" to move playlists without ever seeing your actual login credentials.

  • Access Tokens: These are stored locally in your browser's encrypted session storage.
  • Scope Limitation: We only request the minimum permissions necessary (e.g., "Read Playlists" and "Write Playlists"). We never request access to your billing information or personal emails.
  • Automatic Expiry: These tokens are purged the moment you click "Disconnect" or close your browser session.

During the matching phase, our AI-powered engine temporarily analyzes your library metadata.

  • Technical Identifiers: We access ISRC (International Standard Recording Code) numbers, track titles, and album names to ensure our 95%+ matching accuracy.
  • Real-time Matching: This data is used by our Triple-Engine Matching system to find the correct version of a song (e.g., distinguishing a studio version from a "Live at Wembley" version).
  • No Profiling: We do not build a "taste profile" or sell your listening history to third-party marketing firms.

To maintain our service quality and prevent system abuse, we collect limited, anonymized technical data:

  • Performance Metrics: Success rates of transfers and average processing speeds.
  • Device Context: Browser type and operating system (to troubleshoot UI bugs).
  • IP Addresses: Collected briefly to prevent automated "bot" attacks and fraud, and then anonymized.

How We Use Your Information

Music Switch utilizes the collected data strictly for the following purposes:

  • Facilitating Transfers: To move your curated lists between Apple Music, NetEase, and other supported platforms.
  • Precision Matching: Using AI fingerprints to ensure your rare remixes and live tracks are correctly identified.
  • Service Optimization: Improving our algorithm's ability to find songs on regional platforms like QQ Music.
  • Security & Fraud Prevention: Monitoring for high-frequency automated requests that could jeopardize our API integrity with music providers.
  • Customer Support: If you contact us at privacy@musicswitch.app, we use your email only to resolve your specific inquiry.

Data Retention and Deletion Policy

We have implemented a Strict Non-Retention Policy:

  • Music Library Data: 0 days storage. Data exists only during the active transfer.
  • Browser Session Data: Deleted immediately upon session termination.
  • Session Logs: For technical troubleshooting, minimal logs are kept for 24 hours and then permanently overwritten.
  • Third-Party Sharing: We do not sell, rent, or trade your personal information. Data is only shared with the music platforms you specifically choose to connect for the purpose of the transfer.

Your Rights and Controls (GDPR & CCPA Compliance)

Regardless of where you live, Music Switch provides global privacy rights to all users:

  • Right to Access: You can see every track we are processing in the real-time transfer dashboard.
  • Right to Erasure: Since we do not store your data, your "right to be forgotten" is effectively satisfied the moment your session ends.
  • Right to Withdraw Consent: You can disconnect your Apple Music or YouTube Music accounts at any time via the "Account" menu.

Security Measures

We employ bank-grade security protocols to protect your data in transit:

  • SSL/TLS Encryption: All data moving between your device and our servers is encrypted using 256-bit AES encryption.
  • Local Processing: Whenever possible, the heavy lifting of data organization happens on your local device, reducing the amount of data that ever reaches our servers.
  • API Security: We only communicate via official, verified APIs provided by music streaming services.

Changes to This Policy

Music Switch may update this Privacy Policy periodically to reflect changes in our service or legal requirements. We will notify users of any significant changes by updating the "Last Updated" date at the top of this page. We encourage you to review this policy whenever you perform a large transfer.
