Privacy Policy

We ask for the least that makes a booking or a game work. We buy nothing from a data broker, and there is no hidden profile behind the one you can see. If you sign in with Google or Facebook, they send us your name and email address, and we use those to make your account.

We do not ask for your date of birth, your home address, or a copy of an identity document. A court needs to know who is coming and how to reach them, and that is where it stops.

Some of it is optional and you decide: a photo and a playing level. A phone number and a country are only needed when you book a court, because the host has to be able to reach you and a court only takes players from its own country.

To stop one network from using up our map and place search, or from sending a flood of booking requests, we count searches and booking requests from each internet address, a few minutes at a time. We keep a scrambled form of the address that cannot be turned back into it, and delete it within a day.

OpenDinkers is booking software. We are not a bank and not a payment service, and we hold money for nobody. A player pays the host with whatever the host switched on, so no card number, security code or bank login ever reaches us.

Some hosts, and some group organisers, ask for a screenshot of the transfer. That image goes into a private store rather than the public one. The only people who can open it are you and the person you paid: the host of the court, or whoever collects the money for a group session. The links we make for it stop working shortly after they are made.

A host who takes a paid plan is charged by our biller, who is the seller of record for that payment. Their card details belong to that company and never touch us.

Every field does a job in a booking or a group game. We run no profiling, we score nobody, and nothing here feeds a system that guesses what you might buy next.

That is the whole list below. If something we collect stops having a job on it, the honest thing is to stop collecting it, not to find a new use for it.

Who sees something about you depends on what you do here. The host of a court you booked sees what is listed below. Members of a club or squad you joined see your name, your playing level and whether you are going to a session, and whoever collects a session's money also sees who has paid. Other players see what you chose to show.

Our own small team runs the platform and can look at accounts and bookings, to answer a question or stop misuse. Their screens show the name you display, your playing level, your country, the day you joined, how many bookings and groups you have, and the name on each booking. They do not show your phone number, your email address or a payment screenshot. They do not show your messages either, with one exception: when somebody in a chat reports it to us, the team sees that chat's most recent messages so they can decide what to do. For a host business, they also see the contact email and phone the host gave us.

We sell nothing to anybody, we run no advertising, and we have no arrangement with a company that does. The only firms with any of your data are the ones below, who run the machinery this site is made of.

Old records are deleted on a timer rather than when somebody remembers. The sweeps below run on a schedule, so a record goes shortly after its period ends rather than at the exact minute.

Booking records are the deliberate exception. This is a marketplace where people pay each other by hand, so who paid whom, and when, has to stay answerable long after the game. How long that must be is set by tax law rather than by us.

The protections are in the database rather than in the screens in front of it, which matters because a screen can be skipped and a database rule cannot.

Everything on your profile can be edited or emptied from your account page, and turning notifications off is one switch. None of it needs to be asked for.

Closing your account hides your profile, releases your sign-in address and signs you out. Signing in again within the time in the section above brings the account back. Your booking records stay, for the reason in that section too, and the account page says so before you press it.

You can download a copy of your data from your account page: your profile, bookings, reviews, messages with hosts, groups, notices and your posts and comments, in one file. When that time is up, a closed account is erased for good, as the table above says. One exception: an account that owns a host business is not erased while it owns one. You can email us at hello@opendinkers.com about that.

You can email us at hello@opendinkers.com with a question about your data or about this page.

If the question is about one booking, the fastest route is the host, in the message thread on that court's page. If it is about this page, the FAQ answers the common ones and the date above says when this text last changed.

A cookie is a small file your browser keeps for this site. Ours are only there to make the site work for you. There are no cookies for ads, no tracking across other sites and no analytics.

Signing in: Supabase, who run our database, set the cookies that keep you signed in. Without them you would have to sign in on every page.

Finishing what you started: short-lived cookies bring you back to the right page after you sign in, reset a password or pay a host by card. Each one ends when that step is done.

Remembering your choices: if you press "use my location", we remember the area and its country for about a month, so the map opens where you are and prices show in your own money. We also remember whether you last used the player side or the host side, and that you have seen the cookie notice. We also remember which way you last signed in on this device (email, Google or Facebook), so the sign-in page can mark that button "Last used".

Your browser also keeps a few small settings on your device, such as a notice you closed or whether you turned on notifications. These never leave your device.
