HumShift is published by Zarkon (zarkon.co.uk). This policy describes how the Android app handles data.
HumShift uses the microphone solely for on-device pitch detection so you can hum to raise platforms and open doors. Audio is processed in memory on your device. It is not uploaded, stored for replay, or sent to any server.
Chamber progress, Pro unlock state, and tip acknowledgements are stored locally with shared preferences. No account is required.
Optional in-app purchases are processed by Google Play. We do not receive your payment card details.
HumShift v1 has no ads. Diagnostic event names may be logged locally in debug builds only; they are not sent to a network analytics service.
