Pitchfinch privacy policy

Last updated November 12, 2026. This policy covers the Android app Pitchfinch: Ear Training (com.tinyfair.pitchfinch) published by Tinyfair on Google Play.

The short version

The app works on your phone. We do not have accounts or servers, and we never receive your answers, scores or voice. Data leaves your phone only for ads, purchases, crash reports and anonymous usage statistics (Google) and for a small settings file the app downloads from our website, as described below.

Data that stays on your phone

Scores and progress
Your answers, levels, Ear score, streak, statistics and settings are saved only in the app's private storage on your phone. They are never sent to us, and the ad SDK never receives them.
Microphone (Sing exercise)
Only when you start the Sing exercise does the app ask for the microphone. Your voice is analysed on your phone to find its pitch while you sing. It is not recorded, not saved and never sent anywhere. You can say no and use every other exercise.
Sounds
Every note and chord is generated on your phone. Nothing is downloaded or streamed.
Reminders and widget
The daily reminder is scheduled on your phone by Android. The home screen widget reads your streak from the app on your phone.
Purchases
Handled by Google Play; we never see your payment details.

Settings file from tinyfair.my.id

When it starts, the app downloads a small settings file from https://tinyfair.my.id/config/pitchfinch.json (the minimum app version and how often ads may appear). The request sends no personal data and no identifier. Like any web request, our web host sees your IP address in its standard server logs; we do not use it to identify you or link it to anything else. Android Auto Backup may include the app's data and settings in your Google account backup if you have it turned on.

Ads (Google AdMob)

The free version shows ads from Google AdMob: a small banner on the Today, Exercises and Stats screens, at most one full-screen ad a day after you finish the daily workout (never in your first session), and a video ad only when you choose to watch one, for example for an extra practice session or 24 hours of Pro. There are no ads while a sound is playing or during an exercise. To show and measure ads, Google may collect your device's advertising ID, an approximate location from your IP address, information about ad interactions, and diagnostics. Your answers, scores and voice are never passed to the ad SDK. In the European Economic Area, the United Kingdom and Switzerland the app asks for your consent first, and you can change it later under Settings, Privacy choices. You can reset or delete your advertising ID in your Android settings. See how Google uses information from apps that use its services. Pro removes all ads.

Crash reports (Firebase Crashlytics)

If the app crashes or hits a serious error, it sends a crash report to Firebase Crashlytics, a Google service that helps us find and fix the bug. A report contains the error and where it happened in the code, the app version, the device model, the Android version, and a random installation ID that is not linked to you, your Google account or your advertising ID. It never contains your answers, your voice, your scores or anything that identifies you. Reports are kept for 90 days. See Firebase privacy and security.

Usage statistics (Google Analytics for Firebase)

To learn which features people use and where the app can be better, the app sends a few usage events to Google Analytics for Firebase, such as that an exercise or the daily workout was finished, an ad was shown, or the Pro offer was shown or Pro was bought. Events never contain your voice or anything you type. Firebase adds the app version, device model, Android version, country, a random app instance ID and, when ad consent allows it, your advertising ID. Collection follows your choice (Google Consent Mode). We do not use Google signals, we do not send a user ID, and we do not sell this data. In the European Economic Area, the United Kingdom and Switzerland, statistics are only collected if you allow it in the consent form (Settings, Privacy choices lets you change this). Data is kept for 14 months. See Firebase privacy and security.

Usage statistics (Google Analytics for Firebase)

To learn which features people use and where the app can be better, the app sends a few usage events to Google Analytics for Firebase: that the main screen opened, that a main task finished (for example "saved"), that the Pro offer was shown or Pro was bought, and that an ad was shown. Firebase adds the app version, device model, Android version, country, a random app instance ID and, when ad consent allows it, your advertising ID. Events never contain your answers, your voice, your scores or anything that identifies you, your name, email or anything you type. We do not use Google signals, we do not send a user ID, and we do not sell this data. In the European Economic Area, the United Kingdom and Switzerland, statistics are only collected if you allow it in the consent form (Settings, Privacy choices lets you change this). Statistics are never collected for users under 13. Data is kept for 14 months. See Firebase privacy and security.

Purchases (Google Play)

Pro is sold through Google Play Billing as a weekly, monthly, 3-month or yearly subscription (the yearly plan has a free trial for new subscribers) or a one-time lifetime purchase. Subscriptions renew automatically until you cancel them in Google Play. We do not see your payment details; Google Play tells the app only whether Pro is active.

Permissions

Microphone, asked only when you open the Sing exercise and used only on your phone to hear the pitch you sing (never recorded or sent). Notifications, for the daily reminder you turn on; the reminder is set again after the phone restarts (start at boot). Vibration for answer feedback. No camera, location, contacts, photos or storage permission and no foreground service. Google's ad and purchase libraries add the advertising ID, network state and billing permissions. Internet is used for ads, purchases, crash reports, usage statistics and the settings file described above, never for your answers.

Children

The app is not directed at children under 13 and we do not knowingly collect information from them.

Your choices and deleting data

Pitchfinch has no account and keeps no data on our side. Progress can be reset in the app under Settings, Data. To delete everything Pitchfinch stores, uninstall the app or clear its storage in Android settings (Apps, Pitchfinch, Storage). For ad and statistics data, use Settings, Privacy choices in the app or your Android advertising ID settings. Questions: support@tinyfair.my.id.

Changes and contact

If this policy changes, the new version will be posted on this page with a new date. Questions: support@tinyfair.my.id.
