• Account information: your name and email address, collected when you sign in via Google, Facebook, or email/password.
• Music metadata: file names, track titles, artist names, album names, and ISRC codes from the audio files you choose to process. This data is processed locally in your browser and only sent to our servers to perform playlist matching.
• Streaming service tokens: OAuth access tokens for Tidal and/or Spotify, stored securely in an encrypted session. We never store your streaming service password.
• Usage data: basic logs of actions performed (e.g. playlist created, tracks matched) for debugging and service improvement. No browsing history is collected.
• Payment data: if you upgrade to Pro, payment is processed by Stripe. We do not store card numbers — only a Stripe payment reference.

• To provide the core service: matching your music and creating playlists.
• To manage your account and subscription.
• To send transactional emails (e.g. email verification, password reset).
• To improve the service through anonymised usage analytics.

We do not sell your data to third parties.

Your account data is retained for as long as your account is active. If you delete your account, all personal data is removed within 30 days. Anonymised logs may be retained for up to 12 months.
