Waitz sensor in electrical outletHow does it work? Is my data protected?

Waitz uses custom IoT sensors that scan for radio signals (Bluetooth & WiFi) in an area. Scans pick up laptops, cell phones, wearables, and other connected devices. Total signal activity is analyzed to estimate the number of people. Scans see the MAC address of all devices in the area, which are immediately hashed (cannot be decrypted) on the device. This means that no one, ourselves included, can view specific MAC address information, protecting the privacy of individuals. For more information on Waitz's privacy policy click .

The ֱ Library and Waitz are committed to protecting your privacy. The Waitz service does not collect or keep data on individual people. MAC address information is immediately hashed (cannot be decrypted) and no personally identifiable information is ever processed or stored on Waitz or ֱ Library servers.

What is Waitz?

Waitz was started by 4 college students who were tired of looking around for a seat at their library, so they decided to make an app showing how busy every floor was in real-time! This was a big hit with their fellow students so the Waitz founders decided to continue spreading this service to additional college campuses. Waitz now gives real-time busyness information to hundreds of thousands of college students a day.
