An electronic personal data locker system is described in which personal data is stored, organized, accessed, and/or maintained, among others activities. In an embodiment, the personal data locker system comprises multiple personal data lockers that each store different types of personal information and/or data of a user. The personal data lockers are established by the system and may be integrated with mobile computing devices. The system may enable the sharing of the gathered data with third parties and/or may enable the user to set preferences for what data is to be shared with various third parties. The system may further provide convenience in providing personal data to third parties via a standard application programming interface (API). The system may also enable the finding and/or calculating of user-related insights based on the gathered data through correlation, aggregation, and/or analysis of the user's personal data.
