Privacy Policy

Effective: October 30, 2026 · Applies to: Butgarak (붓가락) for Android and iOS

Butgarak (the "App") is a music app that turns your drawings into Korean traditional music. The App is designed to be used without an account or sign-in. This policy explains what information the App handles and how it is protected.

1. Information we collect

The developer does not collect your personal information or send it to the developer's servers. The App has no developer-operated server and uses no advertising, analytics, or tracking tools.

2. Information stored only on your device

The following is stored only on your device so the App can work, and is never transmitted:

This data is deleted when you delete the App. If you use your device's backup feature, it may be included in your own backup according to the operating system's policy.

3. Microphone

The App uses the microphone, with your permission, only when you use "Draw by humming".

4. Importing and exporting files

Importing work files (.gugak) or MIDI files and exporting video, audio, or work files only involve files you choose. Sharing uses your device's share feature; afterwards, the app you choose handles the file under its own policy.

5. In-app purchase

"Butgarak Pro" purchases are processed by Google Play or the Apple App Store. The developer does not receive your name, payment method, or card details. The App contacts the store only to verify your purchase, which is why it uses internet access. Payment data is handled under each store's privacy policy:

6. Sharing with third parties

Because the developer does not collect personal information, none is shared with or entrusted to third parties.

7. Children

The App does not collect personal information from anyone, of any age.

8. Your rights

The developer holds no personal information about you, so there is nothing to access, correct, or delete on our side. You can remove drawings and settings stored on your device at any time within the App or by deleting the App.

9. Changes

If this policy changes, we will post the update here with a new effective date, and announce significant changes through an app update as well.
