Zuzu Lab (“we,” “our,” or “us”) respects your privacy. We created CourtRobin to help you run a pickleball round robin from your iPhone or iPad: choose who showed up, generate fair rounds, enter scores, and keep standings and ratings from week to week. This Privacy Policy explains what the app does with information.
Your groups, player names, events, rounds, scores, and the ratings worked out from them are stored only on your device, using Apple’s native data framework (SwiftData). We do not have access to this data, and it is never sent to our servers or to any third party, because we operate no servers.
If you have device backups turned on (iCloud Backup or a backup to your computer), your CourtRobin data is part of that backup, which Apple handles under its own privacy policy. Deleting a player, an event, or a group inside the app removes it from your device. Deleting CourtRobin from your device removes all of its data from that device. Because we never receive your data, we cannot recover it or delete it for you.
The names you enter are whatever you type. You are in control of which names you put in the app.
The Dupe rating is this app’s own rating. It is worked out on your device from the scores you enter. CourtRobin is not affiliated with or endorsed by DUPR, and it does not connect to DUPR or any other rating service. If you type in a starting rating for a player, that number is stored only on your device.
CourtRobin can make a summary of an event as an image or as text. This happens only when you tap Share, and it uses the standard iOS share sheet. You choose who or what app receives it, and what you share is then handled by that app or person. We never receive it.
CourtRobin does not contain in-app purchases or ads. The only link in the app opens this privacy policy in your web browser; your browser, not the app, makes that connection.
CourtRobin is a general scorekeeping tool and is not directed at children. Because the app does not collect any information, we do not knowingly collect personal information from anyone, including children.
If this policy changes, we will post the updated version at this address and change the date at the top.
