Privacy Policy for Tunora: Tuner & Metronome

App name: Tunora: Tuner & Metronome Package name: com.kirsulab.tunora Publisher: KirsuLab LLC Contact: hello@kirsulab.com

This policy explains what the Tunora app (the "App") handles, how it is used, and the choices you have. Pitch detection happens entirely on your device, and the sound your microphone picks up is never recorded, stored, or uploaded. The App includes Google AdMob (advertising) and Google Firebase (analytics and crash reporting), which automatically collect limited technical data as described below.

1. Information we do not collect

• The App has no sign-up or login — we never ask for your name, email address, phone number, or contacts.
• We do not record, store, or upload audio. Microphone input is analyzed on your device in real time, only to estimate the pitch of the note you are playing, and is immediately discarded.
• Your settings — selected instrument, tunings you create, A4 calibration, metronome tempo and sound — are stored locally on your device and are removed when you uninstall the App.
• We do not collect your location, photos, files, or any financial or health information.

2. Microphone

The App uses your device microphone only to detect the pitch of the instrument you are tuning. Audio is processed on your device in real time and is never recorded, stored, or uploaded to us or anyone else. The microphone is active only while the tuner screen is open; it is released when you open the metronome or other screens, and when the App goes to the background. You can revoke the microphone permission at any time in your device settings; the metronome works without it.

3. Information collected automatically

To keep the App free and reliable, it includes third-party software development kits (SDKs) provided by Google that automatically collect limited technical data for advertising, analytics, and stability:

• Google AdMob (advertising) — may use your device's Advertising ID, IP address, coarse device information, and similar identifiers to serve and measure ads. Where required, the App shows a consent prompt before serving personalized ads. Learn more
• Firebase Analytics — pseudonymous app-instance identifiers and aggregate usage events (e.g. an instrument selected, a string tuned), used to understand how the App is used. No audio and no personally identifying information are included. Learn more
• Firebase Crashlytics — crash logs and diagnostic data (device model, OS version, app state at the time of a crash), used to find and fix bugs. Learn more

All data transmitted by these services is encrypted in transit.

4. How we use this information

• To show ads, which keep the App free.
• To understand, in aggregate, how the App is used and improve it.
• To keep the App stable and fix crashes.

We do not sell your personal information. App-interaction, crash, and diagnostic data are not shared with third parties beyond Google acting as our service provider; the Advertising ID is used by Google for advertising and analytics as described above.

5. Advertising and your choices

• In the European Economic Area, the UK, and Switzerland, the App shows a consent dialog (Google User Messaging Platform) before serving personalized ads. You can decline personalized ads and will see non-personalized ads instead.
• You can reset or delete your Android Advertising ID at any time in your device settings: Settings → Privacy → Ads.
• You can opt out of personalized ads in your Google settings: adssettings.google.com.

6. Children

The App is a general-audience utility intended for users aged 13 and older and is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the App, contact us and we will help address it.

7. Permissions used by the App

• Microphone — used to detect the pitch of your instrument. Audio is analyzed on your device in real time and is never recorded or uploaded.
• Internet / network state — required to load advertisements and to send analytics and crash reports.
• Vibration — used for haptic feedback when a string locks in tune and in metronome controls.

8. Data retention, deletion and security

Data collected by the SDKs above is encrypted in transit using industry-standard protocols (HTTPS/TLS). Because the App has no accounts and the collected data is pseudonymous, your settings live only on your device and are removed when you uninstall the App.

To request deletion of any diagnostic data associated with your device, email us at hello@kirsulab.com. Data collected by Google AdMob and Google Firebase is otherwise retained and secured according to Google's policies linked above.

9. International transfers

Google may process the data described above on servers located outside your country, including in the United States, under appropriate safeguards.

10. Changes to this policy

We may update this policy as the App evolves. Material changes will be reflected on this page with an updated effective date.
