LocLok provides the following functions:
1. Policy-based location sharing. A user can manage and control how to share real-time locations with whom at what time. A user can set a radius of a "cloaked location" so that others cannot figure out the real location. Technically, the "cloaked location" guarantees a privacy notion, called "differential privacy" which is proposed in the research community recently.
2. Location sharing for meetings. If a user needs to meet another user of LocLok, they can set up a meeting in the app. Then their real locations will be shared with each other until they finally meet. Four notifications, initial meeting proposal, halfway, nearby and meet, will be sent to them for their convenience.
3. Location journaling. A user can query where he/she went at what time because this app tracks the locations of users. All the information will be contained in the app, and nobody else can view the location information.
LocLok uses your location data in the background. Continued use of GPS running in the background can dramatically decrease battery life. To analyze your battery usage, please go to "Settings->Battery".
