Crunch ("we", "our", or "the app") is committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
Crunch does not collect, store, or transmit any personal data. Specifically:
Crunch requests access to your iPhone's microphone solely to power the built-in guitar tuner. Audio is processed entirely on your device in real time. No audio is recorded, stored, or transmitted anywhere.
All app data — your XP, lesson progress, streaks, and badges — is stored locally on your device using Apple's SwiftData framework. This data never leaves your device and is not accessible to us.
Crunch is suitable for all ages. We do not knowingly collect any information from children or any other users, as no data collection takes place.
Crunch does not integrate any third-party SDKs, analytics tools, advertising networks, or external services. The app works entirely offline.
If we update this privacy policy, the new version will be posted on this page with an updated date. Continued use of the app after changes constitutes acceptance of the updated policy.
If you have any questions about this privacy policy, contact us at 93minash@gmail.com.
