Privacy Policy

Last updated: 20 July 2026

This explains what rejam (rejam.app) collects, why, and who else sees it. rejam is operated by an independent developer based in Brazil.

What we collect

Account — your email address and a user ID, handled by our login provider. We do not store your password; we never see it.
Purchases — how many credits you bought, the amount, the currency, and the payment reference. We never receive your card number; Stripe handles that.
What you submit — the song links you paste, the resulting titles, the audio downloaded from those links, and the genres you generate.
Generated audio — the versions rejam produces for you, kept in private storage so they can be played back and downloaded later.
Technical logs — ordinary server logs such as IP address, timestamps and errors, used to keep the service running and to detect abuse.

We do not run advertising trackers and we do not build advertising profiles.

Why we collect it

To run the service you asked for: sign you in, generate music, keep your library.
To process payments and keep an accurate credit balance.
To prevent abuse — for example, detecting attempts to bypass credits.
To meet legal and accounting obligations for sales.

Who processes your data

rejam is a small service built on top of other providers. Each one only receives what it needs:

Provider	What it handles
Clerk	Sign-in, your email and user ID
Stripe	Payment and card data, purchase records
Supabase	Database and file storage — library, credits, audio files
WaveSpeed	The AI generation itself — the song audio is sent there to be re-recorded
Vercel	Hosting and server logs
Our own server	Downloading audio from the link you paste

Note the WaveSpeed row: generating a cover means the original audio leaves our systems and is processed by a third-party AI provider. If that is not acceptable for a particular recording, do not submit it.

We do not sell your data and we do not share it for anyone else's marketing.

Cookies

rejam uses cookies that are strictly necessary to keep you signed in, set by our login provider. There are no advertising or analytics cookies.

How long we keep it

Library and generated audio — until you delete it or ask us to close your account.
Purchase records — kept as long as required for tax and accounting purposes, even after an account is closed.
Logs — kept for a short period, then rotated out.

Generated audio is cached and reused: if another user asks for the same song in the same genre, they receive the existing result. Those files are not linked to your identity.

Your rights

You can ask us to show you the data we hold about you, correct it, delete it, or send it to you in a portable form. Write to hello@rejam.app and we will respond within a reasonable period. If you are in Brazil, the LGPD applies; if you are in the European Union or the United Kingdom, the GDPR applies.

Children

rejam is not intended for children under 13, and we do not knowingly collect their data.

Security

Traffic is encrypted, generated audio sits in private storage reachable only through short-lived signed links, and database access is restricted. No service can promise perfect security, but we take it seriously.

Changes

We may update this policy. The date at the top changes when we do.
