นโยบายความเป็นส่วนตัวPrivacy Policy

Personal data

The app never asks for your name, email, or phone number, has no sign-up, and includes no analytics, ads, or user-tracking tools.

The only data that leaves your device is what's needed to verify a Pro purchase, described below.

Working with the keyboard

The app talks to your keyboard over USB MIDI on your device. All scene and tone values stay on your keyboard and device — they're never sent to any server.

Stored on your device

The app keeps a few values in its own storage on your device: your Pro-unlock status, your language choice, and whether you've seen the intro. These never leave your device and are gone when you clear the app's data or uninstall it.

Pro purchases

Pro is a one-time in-app purchase through the App Store or Google Play, with the entitlement managed by RevenueCat.

When you buy or restore a purchase, the following is sent to the store and RevenueCat to verify your entitlement:

• the purchase token or receipt, and the product id;
• a random user id generated by RevenueCat, not tied to your identity;
• your device model, OS version, country, and language.

This is used to validate your purchase and let you restore Pro on another device. The developer never receives or stores your name, email, or card details — payment is handled by the App Store and Google Play.

Third-party services

• Apple App Store and Google Play Billing — process payments and in-app purchases (Apple's policy · Google's policy).
• RevenueCat, Inc. — verifies and manages purchase entitlements as the developer's data processor (RevenueCat Privacy Policy).

Retention and your rights

Because the app has no user accounts, the developer can't tell which record belongs to whom. Uninstalling removes all local data.

If you'd like the purchase record held by RevenueCat deleted, email the address below and include the purchase date and the store transaction id so the record can be found.

Children

This app isn't made for children under 13, and no personal data is collected from users of any age.

Changes

This policy may be revised. If we make a material change, the date at the top of this page will change.
