Privacy Policy

Last updated: 2026-08-16

What we collect

Your email address, and your Spotify Liked Songs library (title, artist, album, and Spotify URI per track) at the time you upload or connect it. We compute a compact taste profile from your library — top artists, genre mix, heavily-represented albums — which is what powers each day's pick.

What we don't keep

Raw uploaded files (CSV/JSON/ZIP) are parsed in memory and discarded immediately — we never store the original file, only the normalized track list.

Why we collect it

To pick a song you don't already have, avoid repeating past picks, and write an explanation that references your own library. Your reply feedback is stored as standing preferences that shape future picks.

Who we share it with

Resend (email delivery), Stripe (billing), Anthropic (generating the daily pick and explanation from your taste profile — never your raw library), and MusicBrainz (verifying a song is real before we send it). We do not sell your data.

Your rights

You can request a full export or full deletion of your data at any time, below. Deletion removes your library, taste profile, send history, and feedback, and cancels any active subscription.
