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 9 October 2026 · Version 1.3
The short version. One box is free for good. Paid plans start at £120 a year, 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: our contact page.
2. Agreeing to this
Starting your club on Clayside at /setup/ means you accept these terms, our Privacy Policy and our Data processing terms. 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 Clayside up for a club, you need to be someone the club has actually asked to do it.
The Sheet (/sheet/) 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
Clayside is software for running a racket club: its competitions and its register on every plan, and on the club plans the rest of the club as well. Tennis, padel, squash, badminton and pickleball, each scored by its own rules.
On every plan:
- Competitions. Box leagues, all-year club ladders, club championships and social nights. Fixtures and draws are built for you, players enter their own scores with their opponent confirming, and the tables and brackets update themselves. Clause 6 says which plan runs which.
- Finding a game. Members say when they are free and find a game with each other, and each member's level is worked out from their results.
- Your register. Each member's name, contact details, date of birth, gender, a parent's or guardian's details, tags and notes. You can import it from a spreadsheet, and people can ask to join through your club link.
On the club plans, as well:
- The membership. Your own categories, prices and membership year, households, a joining form and renewals, with members' subscriptions collected by Direct Debit into your club's own bank account.
- Courts. Your courts, your opening hours and your members booking them. Only members book, and no money moves for a court.
- Lessons, teams and figures. Lessons arranged with your coaches, your club's own teams picked for the matches they play, and your club's own numbers on its Stats screen.
- A website for your club, at your club's address.
What it isn't, so nobody's surprised: it's not a coaching programme, and it doesn't run a booking page for the public or take payment for a court. It can send everybody at your club a message, but it isn't a group chat and it doesn't replace your WhatsApp group.
4. Your club and your account
- Your club lives at yourclub.clayside.app. The address is yours to use while your club is 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 your club up is the owner. On a paid plan the owner can give other people a role in running it, up to 15 people in all. You're responsible for who you give a role 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, through our contact page.
5. Your players and your register
You decide who's in your competitions and who's on your register. That makes those records your responsibility, not ours.
When you put somebody in a competition or on your register, you're the data controller for what you record about them and we're your processor. Our Data processing terms are the Article 28 annex your committee may want on file, and they form part of these terms, along with the Privacy Policy. In practice that means you confirm:
- You have a proper basis for putting people in your competitions and on your register, the ordinary ones being that they entered or that they are members.
- You'll deal with your own members' requests to see, correct or remove what you hold about them. Most of it you can do 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. Clayside is not the place for medical notes, safeguarding records or a comment about someone you wouldn't say to their face. The activity log keeps what admins type.
Your register needs the most care, because it holds contact details and often a date of birth. Those are your members' records, recorded by you for your own purposes, and you are the controller for every one of them. Two things we ask, and both are in your own interest: record a junior's date of birth if you record anybody's, because that date is what closes the email door for a child and a blank one reads as an adult; and keep the notes field for what it is for. On a club plan, what you may collect through the joining form is up to you, and an application is deleted on the clock published in the Privacy Policy whichever way you decide it. And on a club plan, what you publish on your club's website is yours too: a photo goes up when you tick that the people in it are happy to be there, and an organiser's email or phone appears only when that person has agreed to it in their own app.
We'll only ever use your club's data to run your club on Clayside and keep it working. Not to train anything, not to sell to anyone, and nothing of ours is ever marketed to your members. On any plan a member may add their own address and prove it with a code. What we then send them is about their own play, their own membership, or a message your club sent everybody, and clause 3 of our Data processing terms lists every kind. Nothing else, ever. A member under 18 holds no address at all. 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, up to 15 players, online and shareable. Players enter their own scores. Yours for good (clause 7), and no card at any point. No box admins, promotion, relegation, career stats, club ladders or tournaments. |
| Division | £120/year or £12/month | Up to 125 current members; as many boxes and seasons as you like; promotion, relegation, career stats, the season archive, the club ladders and tournaments. |
| Premier | £220/year or £22/month | Everything in Division, for up to 250 current members. |
| Championship | £380/year or £38/month | Everything in Premier, for up to 500 current members, plus a named person to email and a 30-minute call to set your first season up. |
| County | £650/year or £65/month | Everything in Championship, for up to 1000 current members. |

| Club 500 | £950/year or £95/month | Everything in County, plus the membership and collecting its subscriptions, the court diary, lessons, your club's own teams and its website, for up to 500 current members. |
| Club 1000 | £1650/year or £165/month | Everything in County, plus the membership and collecting its subscriptions, the court diary, lessons, your club's own teams and its website, for up to 1000 current members. |
Above 1000 members there is no card and no button: email us and we'll agree something.
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.
A monthly price is the annual one divided by 10, on both lines, which is why paying for a year costs 2 months less.
How paying actually works
You set a paid plan up with a Direct Debit, through GoCardless, our payment provider. You enter your bank details on GoCardless's own secure page, never on ours, so no account number and no card of yours ever touches Clayside. That is about your club paying us. If your club collects its own subs on a club plan, and you choose to print your account details on your joining form so members can pay by transfer, those are your club's own details, typed in by you and stored in your club's own database. Your members' bank details still only ever go to GoCardless. Every paid plan on both lines is bought the same way, from the plan picker in the app; prefer to arrange it another way, or want an invoice, just email us.
Changing to a different plan part-way through means cancelling the Direct Debit you have and setting the new one up. Nothing is deleted by either step. Moving off a club plan onto a competition plan is the one change we ask you to email about rather than press a button for, because everything a club plan adds goes out of reach, the membership, the money and editing households among it. Your register stays, and you can still read it and change it. Nothing is deleted then either.
Your members' subscriptions are not our money
This is a different thing from the clause above and the two never meet. On a club plan your club connects its own GoCardless account, and your members' subscriptions go from your member to your club's bank. We are not a party to it, we never hold that money, and we never see a member's bank details: they type them on GoCardless's own page.
- We take no percentage of anything you collect. Our fee is the flat plan price above and nothing else. GoCardless charges your club its own fee per collection, under your club's agreement with them, and that is paid to them.
- You decide what to charge and who to charge it to. Categories, prices, pro-rata, waivers, refunds and whether to chase are all your club's, and nothing is collected until somebody at your club presses the button.
- A dispute about a subscription is between your club and its member. We can show you what the software recorded and when; we cannot decide whether somebody owed it.
- A refund is yours to make, from your own GoCardless dashboard. There is no button here that moves money back, by design.
- If you stop using Clayside, that arrangement is unaffected. It is your club's account and your club's relationship with its members, and it was never ours.
- Billed monthly in advance, or yearly if you'd rather.
- Cancel any time, yourself, with the Cancel button in the row of buttons at the foot of the app (it names your plan). No notice period, no cancellation fee, no phone call where someone tries to talk you out of it. You keep your plan to the end of the period you've paid for, then drop back to One Box. Email us instead if you'd rather; it does the same thing.
- 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 club, and we won't delete your data over an unpaid bill. A single failed payment does nothing at all: GoCardless retries it. If the Direct Debit ends for good, your club drops back to the free One Box plan with everything still in it, and your export always works.
7. Trials
A new club starts as a trial with nothing locked off, so you can see it working with your real players and members before deciding anything. No card, and nothing to cancel. The trial runs for 14 days from the day you start. We email you three days before it ends, the day before, and on the day.
Your club is yours from the moment it exists, and it is never deleted for not paying. When the trial ends it carries on as the free One Box plan, with every season, score and member still in it. Your first box keeps taking scores; every box past it stays here and stays readable.
You confirm your email before your club is created, not after: we send a six-digit code to the address you give at /setup and nothing is made until you type it back in. That is why there is no deadline in this section and nothing to lose by missing one. A code that is never used expires within the hour, and the signup is deleted with it. No club was created, so there is nothing to delete.
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 club's address without asking us.
Every plan is sold on how many current members your club has, and the counts are the ones on the pricing page. Every plan, the free one included, runs every sport, singles and doubles, and as many seasons as you like. The free plan is one box. Every paid plan adds as many boxes as you like, promotion and relegation, career stats, the club ladders, tournaments, a sponsor's name of your own, and up to 15 people to help run the club. One paid plan differs from the next in how many members it holds and in the support in clause 10. Within your plan there are no metered usage caps and no per-season charges. If your club grows past the plan it is on, nothing is switched off and nobody is removed. Adding several members at once is what stops, and we count where you are at your renewal and talk to you about it before it reaches a bill. The people who run the club do not count towards that number, and nor does anybody who has left. 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.
A sponsor in your club's app is your arrangement, not ours. A paid plan lets you put one sponsor's name, and a link, at the top of your club's app and at the foot of the pictures you share out of it. Before you take a plan, and on the free one, that slot carries a sponsor of ours instead: one name and a link, on the same terms and under the same content rule. We take no cut, we don't handle the money and we don't introduce you to anyone. Two rules: it must not be a gambling brand, an alcohol brand or anything political, because the app is read by juniors and their parents; and the link has to go to the sponsor rather than back to another club. We can require you to take a sponsor down, and we will if it breaks either rule.
Starting a club. One address can start three clubs in two years, and one internet connection three in a day. That is an abuse control, not a limit on your club: if you genuinely need a fourth, email us and we'll set it up. We also cap how many new clubs the whole platform takes in a day, so a signup can occasionally be refused for a reason that has nothing to do with you. Try again tomorrow, or tell us.
A box league season runs up to 190 days, which is about six months, and can start up to three months from the day you set it up. Three months is the length we recommend: a box league works to a deadline, and that is what players turn out for. Run a longer year as two or three seasons, which is what the rollover is for. There is no limit on how many seasons you run.
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: your register, every result and every season, in one file, one click, from inside the app, or one member's record on its own when they ask for it. 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. Ask by emailing hello@clayside.app from the owner's address; there's no delete button, because what it would destroy is every member's record in one tap. That's genuinely final: the database goes, every file goes with it, and no backup survives it. Download your data first, which is the button in the tools row at the foot of the app.
- How long we keep what, and who else sees it, is in the Privacy Policy. What we're allowed to do with it as your processor, and who else touches it, is in the Data processing terms.
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 from a person, in UK working hours: use Ask Clayside support in your club's app, or our contact page. We aim to answer within 1 working day on Premier and every plan above it, 2 working days on Division, and 5 working days on the free plan.
- 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 club 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 software for a club, used 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. Download your data is in the tools row at the foot of the app, 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 £22/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 your club is 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, the Privacy Policy and the Data processing terms. 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.
Questions about any of this? Ask us. A real person reads it.
