Terms of use

Hazel is a personal, non-commercial project that displays pollen forecasts. It is provided as-is, with no warranty and no guarantee of availability or accuracy.

Pollen data is supplied by the Google Maps Platform Pollen API. Your use of Hazel is therefore also subject to the Google Maps Platform Terms of Service.

Hazel is not medical advice. Pollen indices are forecasts, not measurements of what you are breathing. If pollen affects your health, talk to a clinician rather than a web page.
