Why do I need to give permission to my phone’s microphone?

When you activate a Noise Filter, Here One collects small audio samples (5-10 seconds) of the noise in your immediate environment to improve our filters and service. Audio samples are converted and stored in data form that is effectively indecipherable to humans. If Smart Suggest is enabled, audio samples will be collected, classified, and discarded at frequent intervals. We do not collect audio when your telephone is in use. You can disable the microphone access through your device settings. The privacy of our users is very important to us. See our Privacy Policy to learn more.
