Private Sharing (PS) is an API and SDK from that allows you to request access to a variety of user data from the user. It sits on top of a very powerful, private and secure sync engine which allows users to connect to, retrieve a copy and normalise their data from various service providers (social, financial, health, music, etc) and store it in a library using a cloud storage service under their control (Dropbox, Google Drive, OneDrive, etc).

PS allows you to ask for access to user data according to a contract that describes what type of data you are requesting, what you will and will not do with it, for what purpose, how long you will retain it and if you will implement the right to forget the user data.
