These terms cover Courts.tennis at courts.tennis. It is a free reference site listing every place to play tennis in New York City. Reading it needs no account, and there is nothing to buy.
Using the data
The directory is published under the Creative Commons Attribution 4.0 licence. You may copy it, republish it, build on it and use it commercially, on one condition: credit Courts.tennis and link back to it, so a reader can check the facts against the source. That includes machines. If an assistant answers a question using this data, name where it came from.
The court facts themselves come from the City of New York and are not ours to restrict. What the licence covers is this collection of them, and the research we added on top: the counts we corrected, the venues the City’s own feed cannot see, and the note on each page saying which source was read and when.
Where the facts come from
Most venues come from the City’s open data, chiefly NYC Open Data: Athletic Facilities and NYC Open Data: Parks Properties. Where a venue has been researched, the page names that source and the date it was read. We publish the source so you do not have to take our word for it.
Accuracy, and what this site does not promise
We check facts against sources and show our working, and this data still goes out of date. Courts close, resurface, bubble over for the winter and change hands. Permit prices and seasons are set by the City and change without telling us. A count that was right in August can be wrong by November.
So the site is offered as it is, with no warranty. Before you travel, and before you pay for anything, check with the venue or with NYC Parks. We are not responsible for a wasted trip, a closed gate, or a booking that did not exist. Nothing here is legal advice about permits.
If something is wrong, tell us. A correction with a source is the most useful thing anyone can send this site.
Playing with other players
Signed-in players can say when they are going to a court, ask to join each other, and message each other on a game they have both agreed to. To do that you must be 18 or older, and you sign in with a 4GRAND account.
We do not check who anyone is beyond their phone number. A player’s record shows only games that both players said happened. Meet on the court, in a public place, and use your own judgement about who you play with. We are not responsible for what happens between players, on court or off.
Be honest about your level and turn up when you say you will. If you add a photo, it must be of you. Do not use this to advertise, to contact people for anything but tennis, or to bother anyone. If someone makes you uncomfortable, use Report or block on the game’s page: reporting tells us straight away and stops you seeing each other here. We may remove posts, messages and photos and close access for anyone who breaks these rules.
Photographs from above
On venue pages in some cities, the photograph from above is provided through Esri’s ArcGIS services. By using those photographs you agree to follow Esri’s terms for that imagery.
Links out
Pages link to the City, to venues and to their booking systems. Those sites are not ours and have their own terms and their own prices.
Reading this site with software
You are welcome to. The pages are plain server-rendered HTML, there is a sitemap, and there is a machine endpoint at /mcp that answers questions directly so you do not have to scrape anything. Please be reasonable about how often you ask. The attribution condition above applies to whatever you do with the answers.
Changes
We will change the date above if these terms change. The licence granted on data already published is not withdrawn by a later change.
