Privacy Policy

Last updated: November 12, 2026. This version takes effect on November 26, 2026.

What changed in this version: we added what the App has gained since October: what Dill remembers about you, Dill searching the web, coaches, the "played with" recap, being checked in by a friend, links that open on zuur.app, GIFs, weather, map pictures, videos and link previews and the companies that provide them, and a section for players outside the United States. Two location items are new and are described below: the rough position the App sends when it opens, and being checked in by a friend.

Zuur is a real-time pickleball court community app, operated by Zuur LLC ("Zuur," "we," "us," or "our"). This Privacy Policy explains what information we collect when you use the Zuur mobile application ("App"), what we do with it, and the choices you have.

The short version on location

Zuur does not track you. No one can see your live location — not other players, and not Zuur.

Other players see you only at courts: where you are playing now, and court activity like your recent visits and your regular courts, according to your visibility setting (Everyone, People I follow, or Anonymous). They never see where you are anywhere else.
Zuur does not follow your movements or keep a map of where you have been. What we keep is the courts you have checked in at (the details are below).
Your phone does the work. It watches for courts itself, and tells us when you arrive, now and then while you play, and when you leave.
You can see and delete your court visits and arrival points in Settings → What Zuur Knows.
We never sell your location or share it with advertisers.

The only time anyone sees where you are on the way to a court is if you choose to share a live trip. Only people you follow who also follow you back can see it, and it ends when you arrive or stop sharing.

1. Information We Collect

Information you provide

Account data: your email address, and a password if you sign up with email. If you sign in with Apple or Google, we receive the name and email address they share with us. If you sign in with your phone number, we keep that number, and you may add an email address during setup.
Phone number (optional): if you add and confirm a phone number, or sign in with one, we keep it on your account. We use it only to sign you in and confirm the account is yours. Other players never see it.
Profile data: display name, profile photo, and anything else you choose to add, such as a bio or a self-reported rating. During setup we also ask, optionally, how you heard about Zuur and who invited you.
Games: games you create or answer on the Calendar (the court, time, title, description and who is going), and any note you add to your answer. Players in a game can see who else is going.
Referral rewards: if you invite friends and choose a reward, the details you give us to send it, such as a Venmo username or the email for a gift card (see the Referral Terms).
Prize claims: when you claim a prize with your points, the name and shipping address you give us, used only to review and send that prize (see the Points & Prizes Terms).
User-generated content: messages, voice messages, posts, photos, videos, polls, reactions and reports you create within the App.
Private notes: notes you write about other players, such as their level of play. Only you can see them; the player never can. They are deleted with your account, or with theirs.
What Dill remembers: when you tell Dill, our in-app assistant, something lasting about yourself, such as "I'm left-handed," he keeps it as a short note on his own (up to 30). You can read and delete each note in the App. Dill's memory is on unless you turn it off. With it on, he also uses what Zuur already has about you to answer you: the court you play at most, when you usually play, your rating and the games you are in. He uses this only in your own one-to-one conversation with him, never in a group chat or a court feed. With it off, he keeps no notes and does not use them or your habits; when you ask him to plan a game or find players, he still uses your rating and the court you play at most to do that.
Coaching (optional): if you apply to be listed as a coach, your certification and its number, how long you have coached, the levels you teach, your lesson prices, the courts you teach at and a short description. Our team reviews it and keeps a record of its decision. If you are approved, a Coach tag appears on your profile and at those courts with what you told us (your certification, years coaching, levels, lessons, prices and description), and Dill can suggest you to players looking for a coach. Your certificate number is never shown to other players.
Being suggested for games (optional, off unless you turn it on): if you turn this on, Dill may suggest you to players looking for someone at your level near them. They are shown your first name (or the name on your profile), your rating and roughly how many miles away you play, and they can send you an invitation to a game through Dill.
Counting players at a court (older versions of the App only): the App used to let you count the players at a court with the camera, and no longer does. On a version that still has it, either your phone counts them itself and sends us only the number, or the picture is sent to our AI provider to be counted; we do not keep the picture. The number is stored with the court and the account that sent it; other players can see the number and who sent it. The count does not identify the people in it.

Location

When you allow location access, your phone checks its location to notice when you reach a pickleball court on the Zuur map, including in the background if you choose "Always Allow." What we store is limited to the following:

Court visits: which court you were at, and when you arrived, stayed and left. These records contain no coordinates.
Arrival points: one GPS position taken when you arrive at a court, used to place you on the right court at that venue.
Live trips: when you tell Zuur you are heading to a court, your position during that trip, including while your phone is locked, visible only to people you follow who also follow you back. It is removed when you arrive, cancel, or the trip expires. You can turn live trips off entirely in Settings.
City requests (optional): if you ask us to bring Zuur to your city, the city and the map point you asked from, so we know where players want courts.

We do not store your location when you are away from a court, and we do not keep a history of your movements between courts.

How this works:

On your phone: the checks that notice you are near a court happen on your device. When you have moved a few miles, your phone asks us which courts are in your wider area (about 20 miles around), so it knows which ones to watch for. That request tells us only a roughly 3-mile square you are in, not where you are, and we do not store it.
At a court: when you arrive, your phone sends a location reading so we can confirm you really are at the court. While you are checked in it sends one now and then to confirm you are still there, and one when you leave. Only the arrival point is kept (see above); the others are used for that check and are not stored.
Browsing the map: to load the courts you are looking at, the App sends us the area of the map on your screen, which is often around you, not your exact position. We do not store it.
Courts near you: when the App opens with location allowed, it sends us a rough position, accurate only to within about half a mile, so we can suggest courts near you and tell you what is new there. The first time, if you follow no courts yet, we also follow a few active courts near you for you; you can undo that. We do not store that position.
Checked in by a friend: a player who is at a court, and whom you follow and who follows you, can ask to check you in there with them. Nothing happens unless you say yes, and your own location is not used for it. We keep a record of the ask: who asked whom, at which court, and the answer.

Information we collect automatically

Device information: a push notification token, app version and device model, so we can deliver notifications and support your device. The App also checks for a newer version of itself when it opens.
Dill usage: each time Dill is asked something, we record that it happened, which part of the App it came from, how long it took, how large the request was and whether it was answered, linked to your account, to keep the service working and within its limits. This record does not contain what was said, and we keep it for 90 days. Separately, when an answer seems to have missed (for example, you tell Dill he got it wrong, or ask the same thing again), we keep that question, his answer and your reply for 60 days, without your account attached, so our team can improve him.
Where you joined: once, when you first use the App, the city and state your internet connection appears to come from. It is read from the connection itself, not from GPS, and we keep only the city and state, not your internet address. It helps us understand where new players are coming from, only our team sees it, and you can see it in Settings → What Zuur Knows.
Diagnostics: crash reports and error logs, to find and fix problems in the App. This includes a log of how the App's court check-in worked on your phone (for example, whether a check-in was sent, how accurate the phone's location reading was, and how far you were from the court), without your coordinates. We keep it for 14 days. We also record how smoothly parts of the App run on your phone (for example, how long a screen took to respond), linked to your account, to find and fix slow spots.
Server logs: like any online service, our hosting provider keeps routine request logs for a few days for security and troubleshooting. These can include the map area or court lookup a request was for. We do not use them to follow anyone.
Invite links: when someone opens a Zuur invite link, we record a one-way scrambled (hashed) form of their network address, the time, and their browser type, so that if they join Zuur the friend who invited them gets credit. We never store the address itself, and these records are deleted after 30 days. When you sign up, the App also checks once whether an invite link is on your clipboard (iOS asks your permission) and uses it only to credit that invite.
Zuur signs: when you scan the QR code on a Zuur sign, we record which sign it was, the time, the kind of phone, and the approximate city our hosting provider infers from the network. We do not record your network address or anything that identifies you; we use these counts only to see which signs are working.

2. How We Use Your Information

To provide the App's core features: showing who is at a court right now, your court history and stats, and community messaging.
To send push notifications you have turned on, such as messages and court activity. You can turn them off in Settings.
To detect and address fraud, abuse, or violations of our Terms of Use.
To keep the App working and improve it.

3. How We Share Your Information

We do not sell your personal information. We share data only in these circumstances:

Other users: your display name and photo, and your presence at a court while you are there, according to the visibility you choose in Settings → Active & Visible (Everyone, People I follow, or Anonymous); and in direct messages, when you were last active, unless you set that to Nobody. After a visit, players who were at the court at the same time as you may be shown that they played with you, following that same visibility setting, and never if you checked in Anonymous.
Links that open on our website: posts in court feeds can be seen by other players. When you or anyone else shares a link to a post, a profile, a game or a court, the page on zuur.app that the link opens can be seen by anyone who has the link, including people who are not on Zuur, and a profile's page by anyone who knows the username. For a post it shows the post's words and photo and the author's name; for a profile, the display name and username, and, unless the account is private, the photo and number of followers; for a game, its title, time and court, the host's name and how many players are in; for an invite, the name of the player who sent it.
Service providers that run parts of the App for us, under their own privacy terms: Supabase (database, storage and sign-in), Apple (Sign in with Apple, maps, weather and push notification delivery), Google (Sign in with Google; when you ask Dill for a place, that place's name and the area the map is showing, to find it; pictures of courts from Google Maps and animated emoji, which load from Google to your phone; and Google Meet, if you choose to join a Live Q&A), Expo (push notification delivery and app updates), Anthropic (the AI behind Dill, our in-app assistant: messages, photos and video stills in conversations with Dill or that mention @dill are sent to it to write Dill's replies, and requests you type to Dill, from the court search or the Dill button, are sent to it with the last few lines of that conversation, without your name or your coordinates (to find courts near you, Dill is told only how far each court is from you); when you ask Dill to do something with other players or sessions, the names and session details it looks up for you are sent too; when you ask who is at a court, only the first names of players there whom you follow and who follow you back are sent (never anyone who checked in Anonymous) — everyone else is a count; and nothing is done until you confirm it, to work out what to show you; Dill can also search the web or read a court's public website to answer you, and what he looks for is sent to Anthropic; and your profile photo, which is sent to it to check whether it is a real photo of one person's face for the Face to the Name achievement; only the yes-or-no result and a short note are kept, with that photo's link, and the check runs again only when you change your photo; this check does not create or keep any facial template or measurements, and does not identify you; Anthropic does not use what we send it to train its models), Sentry (crash reports), Cloudflare (our website), Twilio (sends the sign-in and verification codes to your phone number; it receives only your number, and we never share your phone number with anyone for their marketing), Resend (sends our emails, such as sign-in codes and the game invitations you choose to receive; it receives your email address and the message), Giphy (GIFs: the words you search for are sent to it from our servers, without your name, and the GIFs themselves load from Giphy to your phone), and The Weather Company, Open-Meteo, the U.S. National Weather Service and the Iowa Environmental Mesonet (the weather and rain radar at a court: they receive the court's location or a map area from our servers, never your location).
Videos and links players share: when a link is posted, our servers fetch that page to make its preview card, and the picture on the card loads from that site to your phone. When a YouTube, Vimeo, TikTok or Instagram video plays inside the App, or you open a post from X, it loads from that service. In each case that site receives your network address, as any website you visit does.
Legal requirements: if required by law, or to protect the rights and safety of our users.
Business transfers: if Zuur is involved in a merger, acquisition or sale of assets, your information may be transferred as part of that deal. It would stay covered by this Privacy Policy, and we would tell you before it became subject to a different one.

4. Background Location

With "Always Allow," Zuur can notice that you've arrived at a court without you opening the App, which is what lets you appear on the court for other players. With "While Using the App," check-ins start only while Zuur is open; once you are checked in, Zuur can keep your check-in going after you switch to another app, and your iPhone shows a blue location indicator while it does. You can change or revoke location access at any time in your phone's Settings. Doing so turns off court check-ins; the rest of the App keeps working.

5. Data Retention

Account and profile data are kept until you delete your account.
Prize claims, including the shipping name and address, are kept for as long as we need them to send the prize and for our records (for example, tax and accounting), and are deleted when you delete your account unless the law requires us to keep them.
Court visits and arrival points are kept so the App can show your court history, stats and streaks, until you delete them in Settings → What Zuur Knows or delete your account.
Live trip positions are removed when you arrive, stop sharing, or the trip expires.
City requests are kept until you delete your account.
What Dill remembers about you is kept until you delete it or your account. Records of Dill usage are kept for 90 days.
A coach application is kept until you stop coaching or delete your account; the record of our team's decision is kept. Records of friend check-in asks are kept until you delete your account. Court counts from older versions are kept as numbers, with no picture.
Messages you send in chats remain until you delete them, or until an admin removes them for violating our policies, and they stay in the chat after you delete your account (see below). Posts and comments you make in court feeds remain until you delete them or your account. When one is removed and other people had replied to it, only a placeholder remains, with no words, photos or name, so their replies stay in context.

6. Your Choices and Rights

See your location record: Settings → What Zuur Knows shows every court Zuur has recorded you at, and what is stored.
Delete your court history: from the same screen. This erases your court visits and arrival points, and resets the stats built from them. Your profile, achievements and points are kept.
Access and correction: you can update your profile at any time in the App.
Delete your account: Settings → Danger Zone → Delete Account permanently removes your account: your profile and photo, court history, follows, and your place in every chat. As on WhatsApp, the messages, photos and videos you sent in chats stay in those chats for the people you sent them to, shown as from "Deleted account" and no longer linked to you. Your posts and comments in court feeds are removed. Where other people replied to one, it is replaced by a note that it came from an account that no longer exists, so their replies keep their place (as on X).
Notifications: manage push notifications in Settings → Push Notifications.

Your state privacy rights

Depending on where you live (for example California, Virginia, Colorado, Connecticut and other U.S. states), you may have the right to know what personal information we have about you, to get a copy of it, to correct it, and to delete it. We do not sell your personal information, share it for cross-context behavioral advertising, or use it for targeted advertising, and we use your precise location only to provide the App's features. To make a request, email legal@zuur.app from the email on your account (or tell us the phone number you sign in with); we will confirm it is you before we act, and answer within the time the law sets. If we decline, you can ask us to reconsider by replying to our answer. We will not treat you differently for using these rights.

Security and where your data is kept

We protect your information with measures such as encryption in transit, access controls and database rules that limit what each account can read. No system is perfectly secure; if a breach affects your information, we will tell you as the law requires. Your information is stored and processed in the United States.

If you live outside the United States

Zuur is run from the United States, and your information is stored and processed there, where privacy laws may differ from those where you live. We collect and use your information to provide the App you asked for, to keep it safe and working, and, where we ask first, with your permission (such as location, notifications, camera and microphone), which you can withdraw at any time in your phone's Settings. Wherever you live, you can ask us for a copy of your information, to correct it or to delete it by emailing legal@zuur.app, and we will answer within one month. You can also see and delete your court history, and delete your account, in the App at any time. If you are not satisfied with our answer, you may complain to the data protection authority where you live.

7. Children's Privacy

The App is rated 12+ and is not directed at children under 13. We do not knowingly collect personal information from children under 13. In some countries the age at which you can agree to this yourself is higher; if you are younger than that age where you live, do not use the App.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes through the App or by email before they take effect, and you can ask us for an earlier version. Continued use of the App after changes take effect constitutes acceptance.
