Privacy Policy

Clefstep: Music Theory & Ear Training · Effective 13 November 2026

Introduction

This policy explains how Clefstep ("we", "the app") handles information. It applies to the iOS and Android apps.

Key points. There is no account and no server of ours that stores your data. Your progress stays on your device. The free version shows ads from Google AdMob, which process some data (see below). Purchases are handled by the App Store or Google Play. The app has no analytics and no crash reporting SDK.

Data stored on your device

Settings (language, theme, note naming), your streak, progress per topic, your answer history and an unfinished practice session are stored on your device only. We never receive them. Deleting the app deletes this data. Progress is not synced between devices.

What the app does not use

Clefstep does not use your location, camera, microphone, contacts or Bluetooth, and it has no sign-in.

Advertising (free version)

The free version shows ads from Google AdMob: a banner on lesson and progress screens and an occasional full-screen ad after you finish a session. Ads are never shown during a drill. To serve ads, Google and its partners may process data such as your device's advertising or device identifier, IP address, device and app information and ad interactions, under Google's privacy policy. We do not receive this data.

Consent: where required, for example in the EEA and UK, the app shows Google's consent form before ads are requested. You can change your choice later in Settings when the form is available.
Not personalized: Clefstep requests non-personalized ads only. Because of this, the app does not ask to track you across other companies' apps and websites.
Android: ads may use the Android advertising ID, which you can reset or delete in your device settings.
Clefstep Pro: with an active Pro purchase, ads are not shown.

Purchases

Clefstep Pro (monthly, yearly or lifetime) is processed by Apple (App Store) or Google (Google Play) under their own terms and privacy policies. We receive no payment details. The app checks your purchase status with the store when it starts.

Permissions and network

The app connects to the internet only for ads, the consent form and store purchases. On Android it declares the internet permission and the advertising ID permission for ads.

Children

The app is not directed at children under 13 and we do not knowingly collect their data.

Your rights

We hold no personal data about you in our own systems, so there is nothing for us to access, correct or delete. For data handled by Google, use Google's controls and your device settings. Under the GDPR you may contact us or your data protection authority with any request or complaint.

Changes

If this policy changes, the effective date above changes with it.
