Privacy Policy

Effective Date: January 1, 2025

TunerKit ("the App", "we") is committed to protecting your privacy and complies with applicable laws. This policy explains what information we collect, why we collect it, and how long it is retained.

1. Information We Collect

We collect the following information:

Anonymous User ID: Generated via Firebase Anonymous Authentication and used for 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 and used 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 entirely on your device and is never recorded, stored, or transmitted to any server. The microphone is used only while a tuning session is active.

3. How We Use Your Information

To provide and improve the tuner and chord dictionary features
To identify and fix bugs through crash reports
To understand aggregate usage patterns and improve the user 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 information collected by us is provided to 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 removal of analytics data, please 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. The identifier stored in cookies is a browser-level online identifier and may qualify as personal information; however, we do not collect your name, email address, phone number, or any other directly identifying information, and we do not use this identifier to single out any individual.
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 and cookies — Google Analytics 4 (Google LLC), which stores cookies (_ga, _ga_*) in your browser to distinguish browsers. These cookies last for up to 2 years, and you can delete them at any time using your browser's cookie controls.
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.
Outsourced processing and international transfer — the statistics above are processed by a processor acting within the scope of our instructions, which constitutes an overseas transfer for outsourced processing; the following is disclosed under Article 28-8 of the Korean Personal Information Protection Act. Recipient: Google LLC (1600 Amphitheatre Parkway, Mountain View, CA, USA; contact via the Google Privacy Policy). Country of transfer: the United States. Timing and method of transfer: transmitted over the network via cookies from time to time as you use the website. Items transferred: as listed under "What we collect" above. Recipient's purpose of use: generating and analyzing visit statistics for this website, within the scope of our instructions. Recipient's retention period: as stated under "Retention" above. You may refuse this transfer as described under "How to consent, refuse, or withdraw" below, with no disadvantage whatsoever in using the website. We do not provide the data to any other third party.
How to consent, refuse, or withdraw — choose Decline on the banner shown on your first visit and Google Analytics is never loaded; the site remains fully usable. Even after accepting, you can withdraw your consent at any time via Cookie settings; when you withdraw (decline), the related cookies are deleted. As an additional option, you can also remove the cookies 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.
