HearBack
Last updated September 21, 2026

Your music.
Your space.

HearBack is provided by Ahmet Can Guven. This policy describes the app and this website.

Learning, accounts and your sketches

Learning and Play work without an account. If you choose Sign in with Apple, we receive an Apple account identifier and verify your sign-in. We do not request your Apple name or email. A preset musical alias and avatar identify your public competition profile. Your learning answers, corrections, completed lessons, XP, badges and device-specific unfinished sessions are synchronized to our server so you can continue on your devices. Learning synchronization is separate from optional analytics. Play sketches stay on this iPhone, in separate guest and account spaces. We do not upload your artwork. No microphone, contacts or location permission is required.

Fair musical competition

Daily Arena and duel answers are sent to our server for scoring. We retain first answers, results, league and season history, friendship links, invitations and block preferences to operate competition. Public rankings show your musical alias, avatar and Arena points. Apple App Attest verifies participating app installations. Security systems process request metadata and IP addresses to protect accounts and prevent abuse. Competition has no chat or uploaded profile photos.

Optional notifications

Practice reminders are scheduled on your device. Duel invitations and results can use Apple Push Notification service when you enable them. The server stores your device push token and separate invitation/result choices. You can turn either off in account settings, or manage notification permission in iOS Settings.

Purchases

Apple handles payments. RevenueCat checks subscription access using an anonymous app user identifier or your verified HearBack account identifier, product and transaction information, purchase dates, subscription status and technical request information. We do not receive your payment card details. This processing is needed to deliver and restore Pro access. Purchase records are retained as required to administer subscriptions and meet applicable obligations.

Optional product analytics

Analytics are off by default. If you enable “Share usage events” in Settings, we use PostHog’s EU service to understand explicit events such as session starts, answer outcomes, audio errors and paywall activity, together with app/device information and a random installation identifier. We do not record screens, automatically capture taps, collect raw answers or send sketches. You can turn this off in Settings. Turning it off stops new optional events; contact us to request deletion of previously collected information.

No advertising tracking

We do not sell personal data, show advertising or track you across other companies’ apps or websites. RevenueCat is the source for subscription revenue, renewal and refund reporting.

This website and support

This static website has no optional analytics, account or contact form. The hosting provider may process IP addresses and request logs to serve and secure pages. If you email us, we use your email address and message to respond and resolve the issue.

Your choices

You can delete your HearBack account in Account settings. This removes its server learning and social data, revokes HearBack sessions, and queues Apple sign-in token revocation for retry if Apple is unavailable. Your local account data is removed. Access-restricted operational backups expire after 14 days; deletion records are reapplied if a backup is restored. You can also delete individual sketches in Play. Deleting local data does not cancel your Apple subscription. Depending on your location, you may have rights to access, correct or delete personal information, object to processing, or contact your local privacy authority. Contact us to make a request.

Service providers

Children and changes

HearBack is a general-audience music learning app, not a service designed to collect children’s personal information. We will update this page when our practices change and identify the updated date above.

Contact

During the beta, open HearBack in TestFlight and choose Send Beta Feedback for help or privacy requests. Include your iOS and HearBack version. A public support email will be listed here before the App Store release. Please do not send payment card details.
