1. What you are getting

Access to a test version of Cairn, for the purpose of trying it out and telling us what you think. Nothing more is promised: not a particular set of features, not a particular level of availability, and not access for any particular length of time.

2. This is test software — do not rely on it

Cairn is unfinished. It may lose data, show the wrong information, or stop working without warning, and the test environment may be wiped at any time.

**Do not use it as the record of a real event.** If you are testing it alongside a live event, keep your normal paper or existing system running as the real record. Nothing in Cairn is a substitute for that yet, and no safety or welfare decision should rest on it.

It is provided as-is, with no warranty of any kind.

3. Please keep it to yourself

Cairn has not been released. While you are testing it, and for two years after your access ends, please do not:

• Show it, or screenshots of it, to anyone outside the test group,
• Share your sign-in link, or let anyone else use your access,
• Discuss how it works, what it does, or what is planned for it, outside the test group, or
• Publish anything about it, including social media posts and photographs that show the screen.

This does not apply to anything that becomes public through no fault of yours, anything you already knew before you saw Cairn, or anything you are legally required to disclose.

If you are unsure whether you can show something to someone, ask us first. Talking to us about Cairn is always fine — that is the point.

4. What you may not do with it

Please do not copy, modify, translate, decompile, disassemble or reverse engineer Cairn or any part of it, try to extract its source code, or use it to build something similar. Please do not try to get at data or accounts that are not yours, or test its security without asking us first.

Cairn, its design, its code and its name belong to us and stay ours. Nothing here gives you any rights in them beyond permission to use the test version while your access lasts.

5. Your feedback

Tell us anything. Bugs, confusions, things that would not survive 3am in the rain, things we have got wrong about how an event actually runs — all of it is useful, and the awkward feedback is the most useful.

Anything you send us about Cairn becomes ours to use, freely and without payment, including in the finished product. We will not owe you a fee or a credit for it. If you would rather keep an idea for yourself, please do not send it to us.

6. Your personal details

To give you access we hold your name, your email address, and a record of what you do in the app while testing. How we handle that is set out in the Cairn Privacy Notice, which forms part of these terms.

7. Data you put into Cairn

Only enter real information about real people if the event organiser has asked you to and is happy for you to do so. Otherwise please use made-up names and details — the test data will be deleted, and made-up data tests the software just as well as real data does.

Never enter anything you would not be comfortable seeing in a system that is still being built.

8. Access can end at any time

We can withdraw your access at any time, for any reason, without notice — most likely because a test round has finished. You can stop testing whenever you like: just tell us, and stop using it. Sections 3, 4 and 5 carry on applying after your access ends.

9. If something goes wrong

We are not liable for any loss you suffer from using this test version, including lost or wrong data, or anything that follows from relying on it — which is why section 2 asks you not to rely on it.

Nothing here limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be limited

10. General

These terms are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.

If we change them in any material way, we will ask you to accept the new version before you carry on testing.

11. Governing Law

These terms are governed by the laws of your local jurisdiction unless otherwise required by applicable law.
