PrivateKit MIT is a ‘privacy-first’ app that allows you to log your GPS trails on your own phone. The information is stored locally and never shared with anyone (not even with us or MIT) until you explicitly decide to manually export the data. The location log generated by Private Kit cannot be accessed from outside the user’s device. Location information can be imported and exported by the user and used in other projects and applications. Private Kit’s trail generator logs your device’s location once every five minutes and stores 28 days of data in under 100KB of space – less space than a single picture. But what is truly exciting about Private Kit is its privacy protection. The app needs access to your location and motion tracking sensors to work.
