A Locker is a container for personal data, which gives the owner the ability to control how it's protected and shared. It retrieves and consolidates data from multiple sources, to create a single collection of the things you see and do online: the photos you take, the places you visit, the links you share, contact details for the people you communicate with, and much more. It also provides flexible APIs for developers to build rich applications with access to all of this information.
The Locker Project is an open source development effort, permissively licensed, and sponsored by Singly. Singly provides a personal data service based on this technology, and also welcomes its use by anyone for any purpose.
