Privacy Policy

Bunny Metronome (web, WeChat mini-program, iOS / Android) is a no-account tool. There is no sign-up and no user profile.

Local preferences

Settings live only on your device (web localStorage, mini-program storage, App UserDefaults / DataStore): BPM, time signature, sound mode, volume, language, haptic and keep-awake. Clearing app data resets them. There is no cloud sync.

Optional sound pack

The iOS / Android “Sound Workshop” is a one-time optional product (SKU studio.weichao.jpq.soundpack). Default voice counting and the basic clicks stay free. Purchase and Restore purchases are recorded by Apple StoreKit or Google Play Billing. The payment UI is provided by the system store; this app does not collect credit-card or payment details itself. We do not keep a user table and cannot share one receipt across stores.

Network

• Web: Umeng CNZZ (site ID 1281476758) and Google Analytics 4 (measurement ID G-QH9CD00C0V). Page views plus in-app events (play/pause, BPM, meter, sound mode, settings). Those vendors may set their own cookies / client IDs. No name, email, or practice audio. The site also ships a Content-Security-Policy-Report-Only header: it is an observation policy, not an enforced block, and there is no report endpoint.
• WeChat mini-program: umtrack-wx, with useOpenid = false and uploadUserInfo = false. The SDK records page visits; BPM / mode / meter events are sent only when the SDK is present. Automatic PV is not the same as those events.
• iOS: Firebase Analytics records in-app events (open, play/pause, BPM, meter, sound mode, settings). We use an app-instance ID, not advertising IDs (IDFA), and not for cross-app ads. Events go to Google so we can see daily activity. IAP still talks only to the system store.
• Android 2.1.7+: no Firebase Analytics and no advertising / attribution SDK. The app does not send developer-defined product analytics events. Sound Workshop purchase and Restore use Google Play Billing; Google Play provides the payment UI, and this app does not collect credit-card or payment details itself. The Billing SDK / Google Play may process data Google needs for the transaction, fraud prevention, service operation, or diagnostics — that is not Firebase Analytics. Privacy / Support links in Settings open in the system browser. There is no account.
• Builds distributed on Chinese Android app stores are entirely free with no in-app purchase and ship without any analytics SDK — no data is collected. Their in-app “Support us” entry only shows WeChat / Alipay tip QR codes; any tip happens voluntarily inside those apps, and the metronome never handles payment data.
• No microphone, contacts, or location permission. No accounts on any surface.

Children

The app is suitable for music beginners and does not collect personal data from children under 13. No UGC, no social features.
