Private Location Logging for MIT Projects
PrivateKit allows you to log your location once every five minutes and identify areas of overlap with public time-stamped GPS location data. PrivateKit stores this information on your device – storing your last 28 days of location history and location overlap in less than 100KB of space. You can also import prior location history from other apps to quickly build your location history and start comparing for GPS overlap.
PrivateKit is 'privacy-first' by design. Your location history and overlap record cannot be accessed from outside your device unless you choose to export them via email or text. Because with PrivateKit all information is stored locally on your phone and not on servers, you are in control of your data.
