This Privacy Policy (“the policy”) applies to the Badminton, Tennis, Padel, Squash and Table Tennis apps for iPhone, iPad and Apple Watch, including their widgets, and the tournament page at johankool.nl/tournament/ (“the apps”), published on Apple’s App Store by Johan Kool (“I”, “me”, “mine”), and how it affects the users (“you”, “your”) of the apps.

The last update to this policy was made by me on 6 November 2026.

If you object to any of the limitations set forward in this policy you should stop using the apps and uninstall them. I reserve the right to make changes to this policy. Such changes can be recognized by an updated date in the text above.

In short

  • I run no servers for the apps, and I cannot see your data. The tournament web page is a static page: your data goes straight from iCloud to your browser, not through my website.
  • Your data stays on your devices and, if you use them, in your iCloud account and in Apple Health.
  • The apps contain no advertising and no third-party analytics, and never sell your data.
  • Other people only see your data if you share a tournament with them.

The data the apps use

To serve their purpose the apps keep:

  • Players: the names, initials and colors of the players you add, and which of them is you.
  • Matches: the sport, rules, players, start and end times, and scores of your matches, with every point played.
  • Tournaments: their titles and rosters, and which matches belong to them.
  • Preferences: such as your custom rules and the tournament you last viewed.

The apps do not use your location, contacts, camera or microphone. Scores are announced by your device itself.

Where your data is kept

On your devices. All of the above is stored on your devices. Your iPhone and Apple Watch also exchange it directly when they are paired. Your Apple Watch keeps the current or last game available to its widget.

In your iCloud account. If you are signed in to iCloud, the apps sync this data between your devices through your private iCloud account, using Apple’s CloudKit. It is not accessible to me. Apple’s privacy policy applies to iCloud.

Apple Health

Saving to Health is optional, and you can choose per device whether to use it. The apps only have the access you grant them, which you can change at any time in your device’s privacy settings.

If you turn it on:

  • Writing: matches are saved as workouts. Each workout also contains the match’s sport, rules, score, and the names and initials of its players. Anything with access to your workouts can read these details, and Apple Health can keep them after you remove the app.
  • Reading: the apps read heart rate, active energy, walking and running distance and activity rings to show you statistics after a match. These measurements are only displayed. The apps do not store or sync them, and do not send them to iCloud.
  • Importing: the apps read your workouts to keep them linked to your matches, and to add matches you played on another device or with an earlier version of the app. Matches added this way are stored and synced like any other match.

Health data is never used for advertising, and is never shared with me or with third parties.

Sharing tournaments

If you share a tournament from your iPhone, the people you invite can see its title, its matches and their scores, and the names, initials and colors of the players on its roster. You decide per person whether they can add matches or only view them. Sharing goes through iCloud, which also shows those in a share who else takes part. Your other players, matches and preferences are not shared.

You can also copy a web link to a shared tournament. Whoever you share that link with can view the tournament in a browser after signing in with their Apple ID, if you invited them or allowed anyone with the link.

Likewise, people who share a tournament with you can see what you add to it.

You are in control of with whom you share the data from your instance of the apps. The data of the players you add is often about other people. It is your responsibility to share it only in a manner that is according to the wishes of the people to which the data pertains.

The tournament web page

A shared tournament can also be viewed in a web browser, at a link starting with johankool.nl/tournament/. To see it you sign in with your Apple ID through Apple’s own sign-in page; I never see your Apple ID or password. Signing in may add the tournament to your iCloud, as joining it from the app would.

The page then reads the tournament directly from iCloud, using Apple’s CloudKit, and shows it in your browser. It reads only the titles, rosters, players and scores it shows, not the points played. If you shared the tournament yourself, iCloud cannot hand out that one tournament separately, so your browser also receives your other matches, without showing them.

Your browser keeps your sign-in and a copy of what it read, so the page opens faster next time. They stay in your browser only. Choose Sign Out on the page to remove both, for instance on a shared computer.

The page contains no analytics or advertising and loads nothing from third parties. Like any website, it is hosted somewhere: GitHub, which receives your IP address when you visit, as described in GitHub’s privacy statement. Apple’s privacy policy applies to signing in and to iCloud.

Deleting your data

  • Games: you can delete a game on your iPhone or iPad, and iCloud and your paired device will follow. Its workout stays in Apple Health, so the game can return, for instance on a new installation, unless you delete the workout too.
  • Players: removing a player hides them from your lists, but their name is kept because past matches refer to it.
  • Tournaments: archiving a tournament only hides it for you. Leaving a tournament shared with you removes it from your devices; the person who shared it keeps it.
  • The tournament web page: choose Sign Out on the page to remove your sign-in and the copy of the tournament from that browser.
  • Everything: remove the apps from your devices to delete the data on them, and delete the data in the iCloud settings of your device to delete it from iCloud. Workouts can be deleted in the Health app.

As I cannot see or access your data, I cannot delete it for you.

Analytics and advertising

The apps contain no analytics or advertisement code from third parties. Limited anonymized usage and crash reports are used as provided by Apple, if you have chosen to share such analytics with app developers like me.

Tips

Any tips are processed via the App Store. I do not receive your payment details or learn who you are, only anonymized sales reports from Apple. The apps remember that you tipped, to adjust how often they ask.

Contacting me

If you contact me for support, feedback and/or beta testing your email address(es) and name will be collected by me to contact you regarding these functions, but nothing else. I use this information because I have a legitimate interest in answering you, and keep it only as long as needed for that.

Security

I have made a reasonable effort to safeguard your data, but usage of the apps is at your own risk. It is your responsibility to keep both the apps and the operating systems of the devices they run on up-to-date in a timely fashion.

I ask that you report any security defects that you become aware of to me by email (see footer of website) in a timely fashion. A reasonable effort will be made to address any reported issues.

Your rights

You can ask me by email (see footer of website) to access, correct or delete the personal data I hold about you, which is limited to what is described under “Contacting me”. You also have the right to file a complaint with the Dutch data protection authority, the Autoriteit Persoonsgegevens.

I am based in the Netherlands and as far as applicable Dutch and EU laws apply to your usage of the apps.
