Effective date: July 7, 2026
한국어 버전은 아래에 있습니다.
CGDA Tuner ("the app") is a string-instrument tuner for iOS. This policy explains what data the app handles, what it does not collect, and the choices you have. Contact: [email protected]
What we don't collect
- No account, no sign-up. The app never asks for your name, email address, or any contact information.
- Microphone audio stays on your device. The app uses the microphone only to detect the pitch of the note you are playing. Audio is processed in real time on the device and is never recorded, stored, or transmitted anywhere.
- Your settings stay on your device. Preferences such as selected instrument and tuning are stored locally on your device only.
Advertising (Google AdMob)
The free version of the app shows banner ads served by Google AdMob (Google Mobile Ads SDK). To serve and measure ads, Google may collect:
- Device identifiers — such as the advertising identifier (IDFA, only if you allow tracking) or other device-bound identifiers
- Coarse location — an approximate location estimated from your IP address
- Ad interactions — such as which ads were shown and whether they were tapped
- Diagnostics — crash logs and performance data related to ad serving
This data is collected and processed by Google under its own policies:
The app itself does not receive or store any of this data.
App Tracking Transparency (ATT)
On first use, iOS may ask whether you allow the app to track you.
