Privacy policy

Last updated 2026-10-18

The short version

• No sign-up is needed. We identify your browser with a random ID in a cookie so your songs and credits stay yours.
• Uploaded audio is deleted within 24 hours and is never used for training.
• The BPM & key finder, pitch & speed changer and lyric video maker run in your browser — the file never leaves your device.
• We don't sell personal data.

What we store

• Your songs: the prompt or lyrics, style settings and generated audio, so you can play and download them later. A song is public only if you share it or submit it to the Daily Song; you can make it private again from My songs.
• Credits, plan and purchase records (amount, date, Stripe IDs). Card details are handled by Stripe and never reach our servers.
• A hashed IP address for abuse limits (free quotas, votes), kept for a short period.
• Daily Song entries, votes and your streak, with the display name you chose.

Services we use

• fal.ai runs the music, lyrics and stem-separation models. Prompts, lyrics and uploaded audio are sent to it only to produce your result.
• Stripe processes payments. Supabase stores the database and files. Vercel hosts the site.
• Google Analytics measures page views and anonymous feature usage (for example "a song was generated"), without your prompts or lyrics.

Your choices

You can make any song private again from My songs at any time. To delete a song or everything tied to your browser ID or recovery key, email hello@tunesplit.app.
