Privacy policy

The short version

ClapWhistle Phone Finder checks microphone audio live on your Android device to recognize a clap or whistle. It does not record, save, or upload microphone audio. The app has no account and no custom backend.

Microphone use

Microphone access is the core feature. After you tap Start listening, the app reads short audio frames and calculates sound measurements needed to compare them with clap and whistle patterns. Each frame is discarded immediately after those measurements. No conversation, recording, transcript, or audio file is created.

Android displays a microphone privacy indicator and an ongoing foreground-service notification while listening is active. You can stop from the app or that notification.

Settings and local activity

Detection settings, quiet hours, selected alert sound, unlocks, finder counts, false-alarm counts, and streak information are stored locally. A local fallback keeps basic event counts and the text of the most recent crash. Local diagnostics contain no audio, location, message content, advertising ID, or account identifier.

Local diagnostics can be cleared from Progress in the app. All local app data can be removed by clearing app storage or uninstalling. Diagnostic data is excluded from Android cloud backup.

Firebase analytics, crashes, performance, and remote settings

When the production app is connected to Firebase, Google Analytics for Firebase receives anonymous product events such as onboarding completion, listening starts and stops, sound-test results, alert activity, and settings changes. Safe parameters can include listening mode, trigger type, sensitivity preset, duration range, stop reason, device manufacturer, and app version.

Firebase Crashlytics may receive crash and error details plus non-personal app state. Firebase Performance Monitoring may receive startup and detector timing. Firebase Remote Config supplies conservative feature and advertising switches. These services do not receive microphone audio, names, email addresses, exact location, or message content from the app.

Advertising and consent

The free app uses Google Mobile Ads. Google and its advertising partners may process device or other identifiers, IP-derived approximate location, ad interactions, app interactions, and diagnostics for advertising, measurement, security, and fraud prevention. What is used depends on your device settings, region, consent choices, and Google configuration.

Google’s User Messaging Platform checks whether a consent message or privacy-options entry point is required. The basic clap and whistle finder does not require watching a rewarded ad. A rewarded ad is optional for extra sounds and a visual theme.

Read Google’s privacy policy for its processing practices.

Flashlight, notifications, and custom sounds

Optional camera permission controls only the phone’s flashlight; the app does not take photos or video. Notifications show listening status, alert controls, restart guidance, and an optional reminder after listening has stayed off. If you choose a custom alarm sound, the app stores Android’s local document reference and reads that sound only when an alert plays.

Network use and remote settings

Clap and whistle detection works without a network. Internet access is used for Google consent messages, ads, anonymous analytics, crash and performance reporting, and remote feature settings. Microphone measurements are never included in those requests.

Your choices

• Do not grant microphone access; listening will remain off.
• Turn vibration or flashlight off independently.
• Deny notification access, understanding Android may hide convenient controls.
• Use Advertising privacy options in Settings when Google requires that entry point.
• Reset your advertising ID through Android settings.
• Clear local diagnostics or uninstall the app.

Children

The app is a general-audience utility and is not designed or marketed primarily for children. It does not knowingly request a child’s name, contact information, or account.
