Privacy Policy

This page explains how SingLift Sustain handles microphone access, audio, measurement results, purchases, and contact requests.

Summary

SingLift Sustain uses microphone access to measure stable sustained-tone duration. Audio is not recorded or uploaded. Measurement results are saved on your device.

Microphone access

SingLift Sustain requires microphone access for its core measurement function. The microphone is used while you measure a sustained tone.

On-device processing

Measurement is processed on your device during use. Audio is not uploaded to the cloud for measurement.

Audio handling

Audio files are not stored. Raw microphone input is not saved. Singing content is not stored.

Measurement results saved on your device

SingLift Sustain saves measurement results on your device so that measurement history and Personal Best can be shown in the app.

Purchases

5 measurement days are included. Continued measurement after the included days requires a one-time purchase through Google Play. There is no subscription, no automatic renewal, and no ads.

Purchase processing is handled by Google Play. Blue Arc Studio does not receive your credit card details from the app purchase process.

Diagnostics

SingLift Sustain uses Google Play Billing for one-time purchase processing. Google Play Billing may collect diagnostic information about Billing API usage, such as API success or failure and service connection issues. This information may be shared with Google and used for analytics, Play Billing Library performance improvement, and error support. Blue Arc Studio does not use this diagnostic information for advertising or marketing.
