Terms

These terms cover the hosted service — the Klappn that runs at klappn.com, on our servers, with our model key. The code itself is AGPL-3.0 and yours to run; a self-hosted Klappn is governed by that license, not by this page.

The service is run by Klappn (the maintainers of the public repository). To reach us: reply to any mail Klappn has sent you, or open a GitHub issue.

One email address is the whole account — a 6-digit code signs you in, there is no password to keep. Keep your inbox yours: anyone who can read your email can be you here. You must be at least 13 to use the service, and old enough to agree to terms like these where you live.

Your songs are yours. Prompts, loops, arrangements, recordings — we claim no ownership, and you can export and take them anywhere, anytime. You give us just the permission needed to run the service: to store your work, play it back to you, and process it through the model when you ask for changes.

Share links share: a song, set, or event page you send someone plays for whoever holds the link. Don’t upload or record what you have no right to — that one is on you.

On the hosted service we keep the record of the making — your prompts, the model’s work, your edits, what you kept, what you killed — and we will use it to raise Klappn’s own music model, so this tool stops renting anyone else’s brain. That model stays inside this project.

Want out? Say the word — reply to any mail Klappn has sent you, or open a GitHub issue — and your account never touches training. Past included, no questions. Self-host, and none of this exists.

Generation runs on prepaid tokens at the public rate on /open — the whole price sheet is one screen of open code, and any change to it is a commit, never a surprise on a bill. Tokens never expire. The card fee is Stripe’s, shown before you pay and itemized at checkout.

Playing the instrument is free and needs no account. AI composition runs on a plan or on prepaid tokens — there is no free allowance for it. Tokens bought before this change are unaffected and spend as normal.

Tokens buy computation, which is spent the moment it runs, so spent tokens aren’t refundable. If a purchase went wrong, write us — we’d rather fix it than argue.

Event pages let an organizer take RSVPs and sell tickets. The organizer is selling to you; Klappn moves the money through Stripe and keeps a 10% platform fee that includes payment processing, shown to the organizer up front. Whether the night delivers is between you and the organizer — sort refunds out with them first, and pull us in if you get stuck.

Don’t use the service to break the law, to make or spread content that harms people, or to attack the service itself — probing other accounts, scraping the model, reselling access. We can suspend an account that does; for anything short of plain abuse we’ll say what and why first.

The service is provided as-is. We run it with care and in the open, but we don’t promise it will always be up, that generations always land, or that any feature stays forever. To the extent the law allows, our total liability to you is capped at what you paid us in the twelve months before the claim. Some places don’t allow some of these limits — where the law says otherwise, the law wins.

Leave whenever you like: export your music, then write us to delete the account — it all goes. If we ever have to wind the hosted service down, you get notice and time to take everything with you; the code stays open either way. That is the exit these terms can’t take from you.

When these terms change, the change is a dated public commit and the date above moves. Keep using the service after a change and the new terms are the deal.
