Privacy Policy

This Privacy Policy applies to walkthru.earth and its associated platforms, including opensensor.space and Hormones & Cities. We are committed to transparency and prioritize your privacy in everything we do.

Our mission is to detect hidden patterns of daily life and turn them into people-first solutions that support wellbeing in cities. We achieve this while maintaining the highest standards of data protection and ethical data practices.

Website Analytics (Cookieless by Default)

We use a cookieless-first approach to analytics. Before you consent to cookies, we collect only anonymous, aggregated data that cannot identify you personally:

• Page views and navigation patterns
• General geographic region (country level)
• Device type and browser information

With Your Consent (Cookies Accepted)

If you accept analytics cookies, we may collect additional information to improve our services:

• Session duration and engagement metrics

OpenSensor.Space (IoT Sensor Data)

Our IoT sensor network collects environmental data only:

• Temperature, humidity, and air quality measurements
• Atmospheric pressure and weather conditions
• Sensor location (geographic coordinates of the device)
• Timestamp of measurements

This data is environmental in nature and does not include any personal information. Sensor operators voluntarily contribute their data to our open network.
