Privacy Policy

Effective Date: January 1, 2025

TunerKit ("the App", "we") is committed to protecting your privacy. This policy explains what information we collect, why we collect it, and how it is used.

1. Information We Collect

We collect the following information:

Anonymous User ID: Generated via Firebase Anonymous Authentication to track app statistics and usage analytics.
Device Information: Device model, operating system version, and app version for error reporting.
Crash & Error Logs: Collected via Firebase Crashlytics to improve app stability.
App Usage Statistics: Screen views and feature usage events via Firebase Analytics.

2. Microphone Permission

The tuner feature requires access to your device's microphone to detect pitch in real time. Audio data is processed locally on your device and is never recorded, stored, or transmitted to our servers. Microphone access is used solely during active tuning sessions.

3. How We Use Your Information

To provide and improve the tuner and chord dictionary features
To identify and fix bugs via crash reports
To understand aggregate usage patterns and improve the app experience

4. Advertising

TunerKit displays banner ads powered by Google AdMob. AdMob may use contextual signals (such as app category) to serve relevant ads. Behavior-based (interest-based) advertising is not enabled. No personal data collected by us is shared with advertisers.

5. Third-Party Services

Firebase Analytics (Google): Usage analytics and event tracking
Firebase Crashlytics (Google): Crash and error reporting
Google AdMob: Banner advertising

Each third-party service has its own privacy policy. We encourage you to review them.

6. Data Retention

Anonymous user IDs and analytics data are retained for up to 1 year. Crash logs follow Firebase's standard retention policy. Local app data (such as favorites) is stored on your device and is deleted when you uninstall the app.

7. Third-Party Data Sharing

We do not sell or share your personal information with third parties beyond the services listed above.

8. Your Rights

You have the right to access, correct, or request deletion of your data. Since data is tied to an anonymous ID, uninstalling the app effectively removes all locally stored data. For analytics data removal, contact us at the address below.

9. Children's Privacy

TunerKit does not knowingly collect personal information from children under 13.

Appendix. Website Cookies and Visit Analytics

Unlike the other sections, which describe the app, this section applies only to the website (the domain serving this page).

What we collect — pages visited, referral information (UTM parameters), approximate location (country and city level), device and browser type, screen size, and whether a store link was clicked. We do not collect your name, email address, phone number, or any other information that identifies you personally.
Why we collect it — solely to understand how visitors reach this site so that we can improve it. It is never used for advertising or profiling.
Tool used — Google Analytics 4 (Google LLC), which stores cookies (such as _ga) in your browser to distinguish visitors.
Retention — Google Analytics event data is retained for up to 14 months and then deleted automatically. Your consent choice and referral values are stored only in your own browser and are never sent to our servers.
Third parties and international transfer — the statistics are processed on servers operated by Google LLC outside your country (see the Google Privacy Policy). We do not share them with anyone else.
How to consent or refuse — choose Decline on the banner shown on your first visit and Google Analytics is never loaded; the site remains fully usable. If you accepted, you can withdraw at any time by clearing cookies and site data in your browser.

The referral tags (UTM) appended to store buttons do not identify you, are held only for the current browser session, and work regardless of your cookie choice.
