Private Kit, an open source privacy preserving system for using personal information

Private Kit

Help us stop COVID-19.

We’re building the next generation of secure location logging to preserve privacy and #flattenthecurve

Location logs provide time-stamped records of where users have been, allowing them to share information with health officials accurately and quickly. This helps support contact tracing efforts to slow the spread of the virus.

What’s truly special about Private Kit, though, is its privacy protection. Data never leaves users’ devices without their password entry and explicit consent. The location log generated by Private Kit cannot be accessed from outside the user’s device, meaning data transfer occurs only if the user chooses to share it with the researcher.

Private Kit 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.

Developer Setup

Refer to and run the dev_setup.sh for needed tools.

iOS Configuration - First Time Setup

1. Move to ios directory and run pod install
2. If you have any trouble with packages not round, try react-native link from project directory.
3. Look at running commands below.

Running

Install modules: npm install or yarn install (note yarn does a better job at installing dependencies on macOS)

To run, do:

npx react-native run-android

or

npx react-native run-ios --simulator="iPhone 8 Plus"

NOTE: In some cases, the abovementioned procedure leads to the error 'Failed to load bundle - Could not connect to development server'. In these cases, kill all other react-native processes and try it again.
