Your match data is yours, not ours.
Center Ref has no user accounts and runs no servers. Match history backs up to your private iCloud — Apple's infrastructure, your data, your control. This is the short version of the privacy policy.
What we collect
Center Ref does not collect any personal information about you. We do not have user accounts, do not run any servers that hold your data, and do not use third-party analytics SDKs or advertising identifiers. The one exception — third-party crash reporting — is described below.
Crash reporting
Center Ref uses Sentry, a third-party crash-reporting service, to capture crashes so we can fix them. When the app crashes, Sentry receives:
- Apple's standard crash report (stack traces from the crash).
- Your device model, your iOS or watchOS version, and the app version.
- An anonymous installation identifier — a random UUID generated on first launch — used to deduplicate reports from the same device.
Sentry is configured with personally-identifiable information disabled. No IP address, no email, no system username travels with crash reports. Sentry never receives match data, rosters, scores, or any user-entered content — only the crash itself and the device metadata listed above. We use crash reports solely to identify and fix bugs.
Sentry's privacy policy: sentry.io/privacy.
What stays on your device
The following data is created and stored on your iPhone and Apple Watch:
- Match records: teams, division, period structure, score, events.
- Roster information you enter (player names and jersey numbers).
- App preferences (default division, time of day, etc.).
This data is stored using Apple's SwiftData framework, in the local app sandbox on each device.
What backs up to your iCloud
On iPhone and iPad, Center Ref backs up your match records and saved rosters to your private iCloud database via Apple's CloudKit framework. This means:
- The data lives in your iCloud account on Apple's servers, not on ours. Center Ref never sees it.
- Sign in to the same Apple ID on another iPhone or iPad and your matches appear there automatically.
- Upgrade your phone or restore from a backup, and your match history comes with you.
- The Apple Watch app does not use iCloud. It talks only to its paired iPhone via WatchConnectivity, with no network calls during a match.
You control this from iOS: Settings → [your name] → iCloud → Apps Using iCloud → Center Ref. Disable iCloud for Center Ref to keep the app local-only on each device. You can also sign out of iCloud entirely; Center Ref will continue to work without sync.
Watch ↔ phone sync
Center Ref uses Apple's WatchConnectivity framework to send pre-match configuration from iPhone to Watch and to push the final event log from Watch back to iPhone after the match. This communication happens directly between your paired devices and does not transit any third-party server.
What Apple knows
If you download Center Ref from the App Store or use TestFlight, Apple's standard data collection applies — see Apple's privacy policy for details. iCloud sync is governed by Apple's iCloud terms. If you contact us by email, your email service provider can see that message.
Children's privacy
Center Ref is a tool for adult referees. The app does not solicit personal information from anyone, including children. Player names and jersey numbers entered into rosters are stored on your device and your private iCloud (if enabled), and are never transmitted to Center Ref.
Changes to this policy
If this policy changes materially, we'll update the "Last updated" date below and announce the change in app release notes.
