Terms of use
Last updated 12 November 2026. Draft: to be reviewed before paid sales start.
These terms are the agreement between you and James Campbell ("we", "us") for the CrateMate app. By signing in to CrateMate you accept them.
What you get
A personal, non-exclusive, non-transferable licence to install CrateMate on your own Macs and use it for your own DJing, for as long as your licence key is valid. A key covers the number of Macs shown when you buy it. The app belongs to us; you are licensed to use it, not sold a copy.
What you can't do
- Copy, sell, rent, share or give away the app, or share your licence key with other people.
- Reverse engineer, decompile, take apart or extract the code, data or design of the app, except where the law says you may and we can't stop you.
- Copy, download, scrape or extract CrateMate's suggestion data (including what other DJs play next), whether from the app or from our servers, or use it in any other product or service.
- Remove or get around the licence checks, copy protection or tamper protection.
- Use the app, or anything you learn from taking it apart, to make a competing product.
- Remove our copyright notices.
If you break these rules we can switch off your licence without a refund, and we may take legal action.
Subscriptions and payment
Paid plans are monthly and renew until you cancel. Payments are handled by our reseller, Lemon Squeezy, who is the seller of record. You can cancel at any time from the link in your receipt email, and your licence runs to the end of the period you paid for. Refunds follow Lemon Squeezy's refund terms, and we will always consider a fair request sent to james@djjamescampbell.com.
Your music and your data
Your library stays on your Mac. You are responsible for having the right to use the music you play. The privacy notice explains what CrateMate sends and stores, including anonymous set sharing, which you can switch off in Settings (see Sharing your sets).
Third-party names
CrateMate works alongside DJ software such as Serato, Rekordbox, VirtualDJ and djay Pro. It is independent and is not made, endorsed or supported by those companies. Their names belong to them.
No guarantees
CrateMate is provided "as is". Suggestions are a helper for your own judgement, and we can't promise they are right for your set or that the app will never stop working. To the extent the law allows, we aren't liable for lost gigs, lost data or indirect losses, and our total liability to you is limited to what you paid us in the 12 months before the problem. Nothing here limits rights you have by law that can't be limited.
Updates and changes
We may update the app and these terms. If a change matters to you we will say so in the app or by email.
Law
These terms are governed by the law of England and Wales, and the courts there can hear disputes, though you keep any rights you have to use your local courts.
