This Privacy Policy describes how Volleyball Score Keeper: Volli ("Volli," "we," "us," or "our") handles your information. It applies to the Volli app for iPhone, iPad and Apple Watch (the "App").

| Data | Purpose | Storage | Retention |
|---|---|---|---|
| Team names and jersey numbers you type | Labelling the scoreboard and the rotation grid | On your device (App Group preferences) | Until you change it or delete the App |
| Match settings (ruleset, line-up, rotation system, theme, etc.) | Running the match the way you want | On your device (App Group preferences) | Until you change it or delete the App |
| Match history & season stats (scores, sets, dates) | Showing your past matches, head-to-head records and side-out percentage | On your device (SwiftData) | Until you delete it in-app or delete the App |
None of this is transmitted to us or to any third party. It never leaves your device except, on your own devices, between your iPhone and your paired Apple Watch (see Section 3).
Volli uses no third-party analytics, advertising, attribution, or crash-reporting SDK, and does not track which screens you view.
Your first match is free in full, with every feature. After it, scoring a match requires Volli PRO, which also unlocks match history & season statistics, the 5-1 / 6-2 / 4-2 rotation systems, custom rules and all themes. The Apple Watch app, the Lock Screen Live Activity and the widgets are included at no extra cost. Two named third parties are involved only when you buy or restore PRO:
| Provider | Service | Data Involved | More Info |
|---|---|---|---|
| Apple Inc. | Processes the in-app purchase / subscription | Payment and Apple ID details are handled by Apple; we never see them | Apple's Privacy Policy |
| RevenueCat, Inc. | Subscription management — validates and restores your PRO entitlement | An anonymous app-generated user ID, the purchase/transaction (product, status), and basic device/OS info | revenuecat.com/privacy |
RevenueCat acts as a data processor on our behalf for the sole purpose of managing entitlements. The anonymous ID is not linked to your name or email and is not used for advertising or cross-app tracking. All transfers use TLS encryption.
If you use the Apple Watch app, the current score is synced directly between your iPhone and your own paired Watch using Apple's on-device WatchConnectivity framework. This is a local, device-to-device link — it does not pass through our servers. Home Screen widgets and the Lock Screen Live Activity read the current match from a shared on-device container; nothing is sent off your device.
| Processing Activity | Legal Basis |
|---|---|
| Storing your scores, names, settings and history on your device | Performance of a contract / your request |
| Processing an in-app purchase and managing your entitlement (Apple, RevenueCat) | Performance of a contract |
Volli performs no automated decision-making that produces legal or similarly significant effects.
Because your data lives on your device, deleting the App permanently removes all of it — scores, history, names and settings. You can also delete individual matches in the History screen. There is no server-side copy of your gameplay data to request or erase, and your history does not sync between devices. Purchase records held by Apple and RevenueCat are retained per their respective policies.
Volli is a general-audience scoreboard suitable for all ages, including the school and club players who use it and does not collect personal information from anyone, including children. We comply with COPPA and GDPR Article 8: we do not knowingly collect personal data from children, and there are no ads, tracking, or data sharing.
| API | Reason |
|---|---|
| UserDefaults | Store your settings and current match in the app's own App Group so the widget, Live Activity and Watch can read them (reasons: CA92.1, 1C8F.1) |
The RevenueCat SDK includes its own privacy manifest.
| Data Type | Linked to Identity | Used for Tracking | Purpose |
|---|---|---|---|
| Purchases (purchase history / subscription status) | No | No | App Functionality (verify & restore PRO) |
| Identifiers (anonymous RevenueCat user ID) | No | No | App Functionality (entitlement management) |
We collect no other data types and do not engage in tracking as defined by Apple's App Tracking Transparency framework.
Purchase data handled by Apple and RevenueCat may be processed in the United States and other countries. Such transfers are protected by appropriate safeguards, including EU Standard Contractual Clauses and the providers' data processing agreements, plus TLS encryption.
We may update this Privacy Policy from time to time. Material changes will be reflected by an updated "Last updated" date and, where practicable, an in-app notice. Continued use after changes constitutes acceptance.
