EY Tuner

Privacy Policy

Last updated: September 23, 2026

Summary. EY Tuner does not require an account for its main features. Microphone audio is processed on your device and is not recorded, stored, or uploaded. Tuner and keyboard settings are stored locally. Google Play handles purchases.

Information stored on your device

The app stores settings needed to preserve your experience, including language, theme, Magic UI, screen orientation, visible tuner range, note naming and labels, keyboard-label preferences, instrument choice, note-release preference, and whether scale degrees are shown on the tuner.

The app also stores a cached record of access granted through Google Play.

Voice and microphone data

The tuner requests microphone access and processes microphone audio in real time on your device to estimate musical pitch. Audio is used only while the tuner screen is visible and active. It is not recorded, stored, transmitted, or uploaded. You can deny or revoke microphone access through Android settings, although the live tuner will not work without it.

Purchases

Optional lifetime and Support Developer purchases are processed by Google Play Billing. Google Play provides the app with product details and purchase status needed to display offers, grant access, restore purchases, and complete consumable support purchases. EYDEVELOPS does not receive or store your payment-card number or other payment credentials.

Advertising providers

The app uses Unity Ads, Yandex Ads, Liftoff Monetize, InMobi Ads, Unity LevelPlay, and InMobi Choice.

Information you provide

If you contact EYDEVELOPS by email, we receive the information you choose to send, such as your email address, display name, message, and attachments. We use it to respond to your request, provide support, and maintain necessary correspondence. Please do not send sensitive personal information that is not needed for your request.

How information is shared

EYDEVELOPS does not operate its own analytics, account, or cloud-storage service for this version of the app. Google may process information required for Google Play Billing, in-app update checks, fraud prevention, and related Google services. Email providers process information that you send when contacting EYDEVELOPS.

The app can open external pages, Google Play, or your email application when you choose a corresponding action. Those services operate under their own privacy policies.

Retention and deletion

Local app data remains on your device until you clear the app's storage or uninstall the app.

Children's privacy

The app is not directed at children under the age at which they can consent to data processing in their country. If you believe a child has provided personal information directly to EYDEVELOPS, contact us and we will address the request.

Changes to this policy

We may update this policy when the app's data practices or applicable requirements change. The revised policy will be posted at this location with a new update date.
