Terms of Service

Last updated 22 August 2026

These terms cover your use of the hosted Chordia service at chordia.dev. By creating an account you agree to them.

The software and the service are different things

Chordia the software is released under the GNU Affero General Public License v3.0, and your rights to it come from that license, not from this page. These terms govern only the account we host for you at chordia.dev. If you run Chordia yourself, none of this applies to you.

Your account

You need to be old enough to enter a contract where you live, and at least 13. Keep your password to yourself, and tell us if you think somebody else has it. You are responsible for what happens under your account.

One person, one account. Do not create accounts to evade a suspension.

Your music is yours, and it is your responsibility

Chordia does not host, supply or distribute any music. It plays files that are already on a server you control. You are responsible for having the right to hold and play those files, and for the sharing you choose to do with them.

Sharing a library grants specific people access to your server. You are responsible for who you grant that access to, and for the copyright position of what you make available to them. Do not use Chordia’s sharing features to distribute music you have no right to distribute.

What we ask you not to do

  • Break the law with it, or use it to harass, impersonate or endanger anyone.
  • Attack the service: no attempts to break authentication, exhaust capacity, or reach data belonging to other accounts.
  • Scrape or automate against the service in a way that degrades it for other people. The API is there to be used; use it considerately.
  • Upload an avatar or choose a display name containing content that is illegal, or that exists to abuse somebody.

If you find a security flaw, please report it to security@chordia.dev rather than demonstrating it on other people’s accounts. We will not pursue good-faith research reported that way.

What it costs

Playing your own music through the hosted service is free, and it stays free. Two paid plans, Sonic and Super-Sonic, add extras on top: how the app looks, how far back your listening history goes, and what you can do with that history. Nothing that was free before they existed has moved behind them, and self-hosting gives you the complete software either way. Current prices are on the pricing page.

Paid plans

Who you are paying. Payments are processed by Creem, acting as merchant of record. Creem is the seller for the transaction, appears on your statement, and issues your receipt. We never see or store your card details.

Free trial. Every paid plan starts with 7 days free. You get the full tier straight away. Cancel before the trial ends and you are not charged at all; otherwise the first payment is taken when it ends.

Renewal. Plans renew automatically at the end of each period, monthly or yearly, at the price shown when you subscribed, until you cancel.

Canceling. Cancel any time from Settings, under Plan. You keep the paid features until the end of the period you have already paid for, and then the account returns to free. Canceling deletes nothing: your library, playlists and listening history stay as they are, and history beyond the free window becomes visible again if you subscribe later.

Refunds. Email hello@chordia.dev within 14 days of any charge and we will refund it, no questions asked. That covers renewals, not only your first payment. This is in addition to any statutory right you have where you live, which we do not ask you to waive.

Price changes. We will email account holders at least 30 days before a price change affects them, and it will never apply to a period already paid for. If you would rather not continue, cancel before it takes effect.

Failed payments. If a payment fails we keep the plan active for a short grace period while it is retried. If it keeps failing, the account returns to free rather than being closed.

Availability

The hosted service is operated by one person. It is provided without an uptime guarantee, and access may be interrupted by maintenance or by failure.

We may change or discontinue features. If we intend to shut the hosted service down, we will give account holders reasonable notice and enough time to export their data.

Ending it

You can delete your account at any time from Settings. We may suspend or close an account that breaches these terms, and we will say why unless doing so would be unlawful or would compromise someone’s safety.

Warranties and liability

The hosted service is provided “as is”, without warranties of any kind, to the extent the law allows. We are not liable for indirect or consequential losses, for lost data you did not back up, or for anything that happens on a library server we do not operate.

Nothing here limits liability that cannot lawfully be limited, and none of it affects consumer rights you have where you live.

Changes

We will update the date at the top of this page when these terms change, and tell account holders by email before a material change takes effect. Continuing to use the service after that means you accept the new terms.

Getting in touch

Support, billing and anything else: hello@chordia.dev. Security reports go to security@chordia.dev, and privacy requests to privacy@chordia.dev.
