Terms of Service
The deal between your club and us. Short, in English, and without the paragraph that says we can do anything we like.
Last updated 17 July 2026 · Version 1.0
The short version. One box is free for good. A full league is £12 a month, cancel whenever, no notice and no contract to see out. Your data is yours and downloadable as one file at any time, including on the way out. We'll keep the thing running and be honest when we can't. Don't use it to be a nuisance, and don't put anyone's name in it who shouldn't be there.
1. Who you're dealing with
Clayside is a trading name of Agentu Ltd, registered in England and Wales, company number 16191406, registered office 10 Campbell Crescent, East Grinstead, West Sussex, RH19 1JR.
"We" and "us" means Agentu Ltd. "You" means the club, or the person setting one up on the club's behalf. Contact: hello@clayside.app.
2. Agreeing to this
Starting a league at /setup means you accept these terms and our Privacy Policy. If you don't, don't start one, and if you already have, tell us and we'll delete it.
You must be 18 or over, and if you're setting a league up for a club, you need to be someone the club has actually asked to do it.
The Sheet (/solo.html) is different: it runs entirely in your browser and never talks to us. Sections 6, 7 and 9 don't apply to it, because there's no account, no server and no data of yours in our hands.
3. What Clayside is
Software for running a tennis club's box leagues: a round-robin sheet, fixtures, players entering their own scores with their opponent confirming, and standings that update themselves.
What it isn't, so nobody's surprised: it's not court booking, not club membership management, and not a comms platform. It doesn't want your membership list, and it doesn't replace ClubSpark, Spond or your WhatsApp group. It does the one job those don't.
4. Your club and your account
- Your league lives at yourclub.clayside.app. The address is yours to use while you have a league with us; it isn't property and it doesn't transfer. Pick something that's plausibly your club's. Squatting on a name to stop someone else having it isn't on.
- The person who sets the league up is the owner, and can invite box admins. You're responsible for who you hand admin to, and for what they do with it.
- Sign-in is by emailed link or code. Keep your email account secure: anyone who can read your inbox can sign in as you, and we have no way of telling the difference.
- The player link a club posts to a group chat is a key: anyone holding it can enter scores as anyone in that box. That's deliberate (the alternative is forty logins nobody wants), but it's yours to look after. Don't post it publicly.
- Tell us promptly if you think someone's got into your club who shouldn't have: hello@clayside.app.
5. Your players' names
You decide who's in your league. That makes the names your responsibility, not ours.
When you put a player in a box, you're the data controller for that name and we're your processor (see the Privacy Policy, which sets out our instructions and forms part of these terms). In practice that means you confirm:
- You have a proper basis for putting your members' names in a league, the ordinary one being that they entered it.
- You'll deal with your own players' requests to correct or remove a name. You can do both yourself in the app in seconds, which is faster than we could ever do it for you.
- You won't put anything in that doesn't belong in a box league. It's a name and a score. It is not the place for medical notes, safeguarding records, home addresses, or a comment about someone you wouldn't say to their face. The audit log keeps what admins type.
We'll only ever use your club's data to run your club's league and keep it working. Not to train anything, not to sell to anyone, and never to email your players, who have no address with us and never will. We do send club owners and admins the odd note about Clayside itself, with an unsubscribe on every one.
6. Plans and paying
| Plan | Price | What you get |
|---|---|---|
| The Sheet | Free, forever | One box, on your own device. No account, no server, nobody else sees it. |
| One Box | Free, forever | One box, online and shareable. Players enter their own scores. Not a crippled version: yours for good once you claim it (clause 7), and no card at any point. |
| Full League | £12/month | Unlimited boxes, players and seasons; as many box admins as you have boxes; promotion, relegation and the season archive. |
Prices are in GBP and include VAT. Agentu Ltd is not VAT registered, so no VAT is charged. If that changes we'll tell you before it hits a bill.
Early bird
The first 10 clubs to take Full League pay £8/month instead of £12, or £80 for the first year instead of £120. That rate is yours for as long as you keep the subscription running without a break. Cancel and come back later and you come back at the price of the day.
How paying actually works
Being straight with you: there's no checkout page yet. Full League is arranged by talking to us: the "Ask for Full League" button in the app, or an email. We'll set up a Direct Debit or send an invoice, and your league gets switched over. No card details ever touch Clayside, because Clayside can't take them.
- Billed monthly in advance, or yearly if you'd rather.
- Cancel any time: email us. No notice period, no cancellation fee, no phone call where someone tries to talk you out of it. You keep Full League to the end of the period you've paid for, then drop back to One Box.
- No automatic refunds for part of a month, but if we've taken money for something you couldn't use, ask. We'd rather refund it than argue about it.
- Price changes get 30 days' notice by email, and never apply to a period you've already paid for. Don't like it, cancel; you won't be billed at the new rate.
- If a payment fails we'll chase it by email before anything happens to your league, and we won't delete your data over an unpaid bill. Worst case it goes read-only until it's sorted, and your export always works.
7. Trials
A new league starts as a 14-day trial so you can see it working with real players before deciding anything. No card, and nothing to cancel.
Confirm your email during those 14 days and the league is yours to keep on the free One Box plan. That's what "claiming" it means. Don't, and the league and its database are deleted in full at the end of the trial. Not archived, not suspended: deleted, because a league nobody claimed is a league nobody wanted, and holding a stranger's players' names for ever isn't a favour to anyone. We'll email you before it happens, to the address you gave.
8. Fair use
Don't use Clayside to:
- Break the law, or help someone else to.
- Store other people's personal data without a right to.
- Harass, impersonate or abuse anyone, including in a player name or a free-text note.
- Attack it: probing for holes, breaking the rate limits, scraping other clubs, or trying to reach a club that isn't yours. (Found a real bug? Please tell us. That's welcome, and different.)
- Resell it or run someone else's clubs on your league without asking us.
There are no hard usage caps on Full League: "unlimited" means unlimited for a tennis club. If your usage looks less like a tennis club and more like a data centre, we'll get in touch and talk about it before we do anything.
9. Your data
It's yours. It stays yours. You can take all of it, any time, without asking.
- You own your club's data. We don't claim any right to it beyond running the service for you.
- Export whenever you like: every player, every result, every season, in one file, one click, from inside the app. No support ticket, no waiting, no charge, and it works just as well on your last day as your first. A hostage isn't a customer.
- Ask us to delete it and we'll delete the lot within 30 days. That's genuinely final: the database goes, and no backup survives it. Export first.
- How long we keep what, and who else sees it, is in the Privacy Policy.
10. Uptime, support and changes
We work to keep Clayside up and quick, and it runs on Cloudflare's network for exactly that reason. But we don't offer a formal uptime guarantee or service credits, and it would be dishonest to print a number we can't stand behind. If it's down, it's down, and we'll be working on it.
- Support is by email, from a person, in UK working hours: hello@clayside.app. Full League clubs go to the front of the queue. We aim to answer within two working days.
- Planned maintenance we'll flag in advance where we can, and keep to quiet hours.
- We'll add things and change things. If a change takes away something you rely on, you get 30 days' notice by email, not a surprise. Features listed as "coming" are our intent, not a promise, and shouldn't be why you sign up.
11. Ending it
You: any time, no reason needed. Email us and we'll close it, or just export and stop using it.
Us: we can suspend or close a league if it's being used to break the law or section 8, if it's putting the service or other clubs at risk, or if a bill goes properly unpaid after we've chased. Except where something is serious enough to need stopping immediately, we'll warn you first and give you a chance to put it right. Suspension doesn't delete anything, and your export keeps working.
If we ever shut Clayside down, you get at least 90 days' notice and your data stays exportable throughout. Nobody should lose their club's history because our business plan didn't work.
12. Who's liable for what
Here's the part every service has, written to be read rather than skipped.
What we don't promise: that Clayside will be perfect, uninterrupted, or free of bugs. It's provided as it is. It's a box league, run by people, and someone will type the wrong score. The confirmation step and the audit log are there because we know that.
What we won't cover: lost profits, lost business, lost goodwill, or anything we couldn't reasonably have seen coming. Nor data you lost that you could have exported. The button is right there, it's free, and it always works.
Our cap: if we do owe you something, our total liability is limited to what you've paid us in the 12 months before the problem, and if you're on a free plan, to £100. We'd rather write that down than pretend a £12/month product carries an insurer's balance sheet.
What we never limit, because the law rightly won't let anyone: death or personal injury caused by our negligence, fraud or fraudulent misrepresentation, and anything else that can't be excluded under UK law.
Your side: if we get a claim because of what your club put into Clayside (a name you had no right to use, say), that one's yours to cover.
If you're using Clayside as a consumer rather than for a club, nothing here takes away your statutory rights under the Consumer Rights Act 2015.
13. Who owns what
We own Clayside: the software, the name, the design. You get the right to use it while you have a league with us, and nothing more. Don't copy it, resell it, or take it apart to rebuild it.
You own your club's data, as section 9 says. If you send us an idea for a feature and we build it, we own what we build, but we'll be pleased you asked, and no, we won't be sending you a bill for it either.
14. The legal bits
- Governing law: England and Wales, and the courts there deal with any dispute.
- Changes to these terms: the date at the top moves. Anything material gets 30 days' notice by email to club owners first. Carry on using Clayside after that and you've accepted it; if you'd rather not, cancel. You'll owe nothing.
- The whole agreement: these terms plus the Privacy Policy. Not a sales email, not something someone said on the phone.
- If a clause fails, the rest stands.
- Not enforcing something once doesn't mean we've given it up.
- Third parties: nobody outside this agreement can enforce it under the Contracts (Rights of Third Parties) Act 1999.
- Transfer: you can't transfer this agreement without asking us. We can, if the business is sold. These terms and the Privacy Policy would bind whoever took it on.
- Things outside anyone's control (Cloudflare falling over, the internet having a bad day) aren't a breach by either of us.
