Terms of use

Last updated 3 November 2026

1. Who this is between

Back2Back is a desktop app for DJs and a website for anyone to listen to live sessions on. These terms are between you and the people who run it (“we”, “us”), who run Back2Back free of charge and not as a company. By creating an account, downloading the app, playing in a session or commenting, you agree to them. If you don’t agree, please don’t use Back2Back.

2. Your account

• Use a real email address. It is how you sign in, and how we reach you about your account.
• Keep your password to yourself. What is done with your account is treated as done by you.
• One account is for one person. It is signed in in one app and one browser at a time: signing in again in either place signs out the one before it.
• Your handle, name and picture must not pretend to be somebody else.
• The chat feature is not a secure messenger. Messages are encrypted on our server, but not end to end. Don’t use chat for anything confidential or private.

3. The app

You may install the Back2Back app and use it for your own DJing for as long as these terms apply to you. It will change and a version may stop working with the service until you update it.

The Back2Back app, this website and the service behind them are © 2026 Back2Back. All rights reserved. You are given permission to use it, and nothing more: don’t sell it, rent it out, copy it, take it apart to rebuild it (beyond what the law lets you do, for example to make your own software work with it), or pass it off as your own. The open-source components it is built with keep their own licences, which are listed under Acknowledgements and nothing in these terms limits what those licences let you do with them: two of the app’s files, translated from Deep Symmetry’s code, are under the Eclipse Public License 2.0, and their source code is in the notices listed there. As far as the law allows, the authors and contributors of those components give no warranty or condition of any kind for Back2Back and accept no liability for any loss or damage arising from it.

4. Your equipment

Back2Back is unofficial software. It works with PRO DJ LINK equipment by speaking to it over the network. It is not made, endorsed, tested or supported by AlphaTheta Corporation or Pioneer DJ and they cannot help you with it. A firmware update to your players or mixer may stop it working.

While you are in a session the app sends commands to your players. You use it with your equipment at your own risk. Keep backups of your music and have another way to play at an event if you rely on the equipment you are using with Back2Back.

5. Music, and the rights in it

• You are responsible for everything you play. Music is protected by copyright. Playing it to an audience over the internet usually needs permission from the people who own it, often through a collecting society and the rules differ from country to country. You confirm that you have whatever rights and licences you need for every track you play in a session, wherever your listeners are.
• Back2Back gives you no licence to any music. and having an account does not mean your sets are licensed.
• A public session is a broadcast. Anybody with the link can listen, with or without an account. A private session is not listed and anybody with its private link can listen — its DJs share that link. That is a broadcast to whoever has the link, with the same responsibility for the music. It is recorded just as a public one is.
• Recordings. Every session is recorded and its recording is there to download for 3 days after the session ends, for the DJs. Then it is deleted and cannot be recovered. We may download and listen to a recording, public or private, only to investigate a report or a suspected breach of these terms; our privacy policy says how. Recording starts the moment a session starts, in a public session and a private one alike. What you do with a recording you download is your responsibility and you need the same rights to share it as you needed to play it.
• On-Air time is limited. Each account has an amount of time a week it may spend in sessions, set by its tier (1 hour a week on Rookie, 3 hours on Pro and no limit on Ultra), which is shown in your account preferences. It counts from a session’s first track for as long as you are in the session, on-air or waiting for the other DJ to handoff and comes back in full every Friday at 05:00 UTC. Once your On-Air time has run out you may listen and rejoin a session you are in, but not take over or start a new one; when nobody left in a session has any, the session ends when the track that was playing ends. We may change how much On-Air time an account has at any time. Listening to other sessions on the Live now page does not reduce your allowance — only participating in sessions does.
• Handing off copies a track. Handing off sends a copy of the track that is playing to the other DJ’s computer, so that their player can carry it on. You confirm you are entitled to do that with every track you hand off. If you receive a track this way, it is there for that handoff purposes only: do not copy it, keep it or pass it on. The app deletes it from its own data folder on your computer when the handoff is over and deletes anything left behind when it quits or next starts.

If you own the rights in something played on Back2Back and object to it, see Copyright and takedowns.

6. What you post

Your name, handle, picture, session names, DJs-wanted posters, comments and messages are yours. You give us permission to store and show them as far as running Back2Back requires, for as long as they are on it. Session names, your name and handle, your public page (with your posters, the ones up and the ones that have come down that you have not deleted) and your comments on sessions can be seen by anybody. A private chat between users is kept encrypted on our server, not end-to-end encrypted (see Privacy).

Don’t post anything illegal, hateful, harassing, threatening or sexually explicit; anything that gives away somebody else’s private information; spam; or anything that pretends to come from somebody else. The DJs of a session can remove comments from it and stop people commenting in it. Anybody can block another account from its public page, which stops everything between the two of them — invitations, friend requests, follows, messages, comments and session visibility/ joinability. We can remove anything and suspend or close any account that breaks these terms or the law or puts Back2Back or the people using it at risk.

7. Telling us about a problem

To report a comment, a poster, a profile, a message, a session, a DJ, a listener or anything else on Back2Back that you think is illegal or breaks these terms, contact help@back2back.music with “Report” in the subject and say where it is: the session, the DJ’s handle, and when. Anybody can report, with or without an account. We read every report and decide what to do, which can be removing the content, ending a session or restricting or closing an account; if you ask, we tell you what we did. If something of yours is removed or your account is restricted and you think we got it wrong, reply to the email we sent you or write to the same address with “Complaint” in the subject and we will look at it again. For a copyright complaint, see Copyright and takedowns.

8. Emails

We email you a code to confirm your email address and about your account when we need to. If you follow a DJ we email you when they schedule a session or put a cancelled one back on, shortly before it and when they go live in a session they did not schedule (a cancellation is in your notifications, not your inbox); unfollow them or use the email toggle switch that is displayed on the DJs account (after following) to stop those. We do not send advertising.

9. On-Air time and tiers

Back2Back is free to use. Every account is on one of three tiers and each tier has a specified On-Air time weekly allowance (section 5): 1 hour on Rookie, 3 hours on Pro, and no limit on Ultra. Everything else is the same on every tier.

Every account starts on Rookie. Pro comes at 1,000 followers and Ultra at 10,000. A tier you have reached stays yours if your followers later fall below that number. We may also give an account a tier for good or for a specified amount of time. We will communicate this through email where applicable. We may change what a tier gives and how many followers it comes at at any time.

10. The service may change or stop

Back2Back is run without any promise that it will be available, fast, or free of faults. We may change it, limit it or shut it down at any time.

11. Our responsibility to you

Back2Back is provided “as is”. As far as the law allows, we make no promises about it and we are not responsible for: a set that drops out, stops or sounds wrong; a lost booking, fee, income or audience; damage to or loss of your music, data or equipment; what other people play, say or do on Back2Back; or anything we could not reasonably have foreseen.

12. Ending it

You can stop using Back2Back at any time and delete your account in account preferences. Sections 5, 6, 9 and 11 continue to apply while you used it.

If we need to look into something. We can disable your account while we look into something that has happened, such as a possible breach of these terms, a complaint or a takedown notice. While it is disabled you can still sign in and listen, but nothing else: you can’t play or join sessions, comment, put up posters, edit your profile or download recordings. Your profile is still publicly visible but we may remove content if it breaches our terms. Whilst an account is disabled nothing is deleted and we’ll be in contact with the next steps. Once we have investigated, we will either enable your account again, as it was, or, if you have broken these terms, it may be deleted.

13. Changes to these terms

We may update these terms. The date at the top of this page says when they were last updated. If a change matters, we will tell you on the website or by email before it applies. Using Back2Back after that means you accept the update terms.

14. Law

These terms are governed by the law of England and Wales. If you are a consumer living somewhere else, you keep any protection the law of your own country gives you and you can bring a claim in your own courts.
