Privacy Policy (English)

Last updated: 2026-08-02

Overview

Melody Eraser processes audio entirely on your device. The app itself has no server, no account system, and does not collect, store, or transmit personal information.

Your audio files

• Imported and exported audio files are stored only on your device and are never transmitted anywhere.
• All audio analysis and processing happens on-device.

Advertising (free tier only)

The free tier shows banner ads and rewarded (video) ads served by Google AdMob. To deliver ads, Google may receive device information such as the advertising identifier, IP address, and device type.

• Your advertising identifier (IDFA) is used for ad personalization only if you tap "Allow" in the iOS tracking permission dialog. If you do not allow it, non-personalized ads are shown instead.
• Depending on your region (such as the EU or certain US states), a consent screen may be shown, and ads are served according to your choices.
• For how Google handles data, see:
  • Google Privacy Policy
  • How Google uses data in ads
• If you purchase Pro (one-time), no ads are shown at all.

In-app purchases

• Payment for Pro (purchase and restore) is processed by Apple (App Store). The app never receives your payment details.
• Your purchase status is recorded only on your device.

Settings

Playback settings (skip seconds, output volume, etc.) and the number of ad-unlocked slots are stored only on your device and are never transmitted.

Children

This app is not directed at children.
