# Clayside > Clayside runs box leagues and club ladders for tennis, padel, squash, badminton and pickleball clubs. Players open a link, tap their own name and enter a score. The opponent confirms, or the score confirms itself after three days, and the table updates. No accounts, no passwords, no app to install. A club holds a player's name and nothing else. Clayside is built and run by Daniel Byrne through Agentu Ltd, a UK company (16191406). It does one job. It is not court booking, membership or payment software, and clubs are told on the home page to keep using ClubSpark or Spond for those. ## What it does - Box leagues: automatic fixtures, live standings, and promotion and relegation drafted at the end of a season with every tie-break explained. - A club ladder with an Elo-style rating, recomputed from the match log rather than stored. - Players enter their own scores from a link. There is no account to create and no password to forget. The opponent confirms, or the result confirms itself after three days. - Singles and doubles boxes, and boxes that play everyone once or twice. - Walkovers and retirements recorded as what they were, not as invented scores. - 13 scoring formats across 5 sports, with configurable points for a win, a bonus set and a straight-sets loss. - Career stats across seasons, and every past season readable for as long as the club is there. - One-click export of everything. A club that stops paying goes read-only and keeps its data. - Up to 10 league owners on every plan, free included, so a league survives a volunteer handover. - A season runs up to 14 weeks and no plan runs more than 20 boxes. ## What it does not do Court booking. Membership records. Subscriptions or payment collection. Coaching or lessons. A native app. Push notifications. Arranging matches for people. Reminders. It holds a player's name and nothing else: no email address, no phone number, no date of birth, which is the short answer to a junior safeguarding question. There are no analytics, no trackers and no third-party fonts on any page. The company is a UK one and club data is created in the EU. ## Pricing - **One Box**: free forever. 1 box, up to 12 players a box, no box admins. - **Division**: £75 a year. 3 boxes, up to 16 players a box, 1 box admin, promotion and relegation, career stats. - **Premier**: £150 a year or £15 a month. 10 boxes, up to 16 players a box, 5 box admins, promotion and relegation, career stats, the club ladder. - **Championship**: £220 a year or £22 a month. 16 boxes, up to 16 players a box, 16 box admins, promotion and relegation, career stats, the club ladder.
