Privacy Policy

Effective date: October 3, 2026

EarFit is operated by Rudolf Cicko in the Czech Republic. Contact: rudolfcickodev@gmail.com.

Overview

EarFit is designed to work without an account. Your musical profile, exercise history, accuracy, practice time, XP, streak, settings, and daily workout state stay on your device. EarFit does not transmit this information to us.

Information on your device

EarFit stores the preferences and practice records needed to personalize training, including your onboarding choices, daily goal, reminder preference, daily heart balance, exercise answers, response times, adaptive skill statistics, XP, streaks, and local workout state. Removing EarFit removes this local app data, subject to device backups you or Apple manage.

Audio and reminders

Exercises generate audio on your device. Optional singing exercises use the microphone only while the exercise is open to estimate pitch on device. Microphone audio is not recorded, saved, or transmitted. Practice reminders are local notifications scheduled on your device; they do not require a server or remote push-notification service.

Optional purchase

EarFit's training features are free. In versions with ads, an optional one-time App Store purchase removes them and grants unlimited hearts. Apple processes payment and supplies purchase entitlement information to EarFit, which is used to decide whether to request ads and apply unlimited hearts. EarFit does not require a subscription.

Feedback

If you choose to send feedback from EarFit, your mail app shows the recipient and message before you send it. We receive only the information you deliberately include in that message and use it to respond to support requests or improve EarFit.

Advertising

Some versions of EarFit may show banner ads on Today and Practice, a full-screen ad at a completed-lesson break, and an optional rewarded ad that grants three hearts using Google Mobile Ads. A three-question practice drill offers a non-ad way to earn one heart. When ads are enabled, Google may process information such as your IP address, device identifiers, ad interactions, and diagnostics to deliver and measure ads, subject to your choices and applicable law. EarFit requests any required advertising consent before loading ads and provides a way to revisit available privacy choices in Profile. EarFit does not send your musical profile, practice answers, progress, or microphone audio to Google. See Google's Privacy Policy for more information about Google's processing.

Changes

We may update this policy as EarFit changes. The effective date above will be updated when we do.
