Personal data service

Personal data services or personal data stores (PDS) are services to let an individual store, manage and deploy their key personal data in a highly secure and structured way.[1]

They give the user a central point of control for their personal information (e.g. interests, contact information, affiliations, preferences, friends). The user's data attributes being managed by the service may be stored in a co-located repository, or they may be stored in multiple external distributed repositories, or a combination of both. Attributes from a PDS may be accessed via an API. Users of the same PDS instance may be allowed to selectively share sets of attributes with other users. A data ecosystem is developing where such sharing among projects or "operators" may become practicable.[2]

Open Source ProjectsEdit


Note: Cloud-based PDSes are sometimes called personal data clouds or personal clouds.

Development ToolsEdit

  • Dogsheep Project - Build your own Personal Data Warehouse. Dogsheep is a collection of tools (open-source) for personal analytics using SQLite and Datasette (Python).[3]


  • - an open source, PDS with a centralized underlying attribute store as well as an API to enable bi-directional attribute updates from external websites and services. The APIs are based on standards and include WebDav, SPARQL and linked data. Data formats exchanged include RDF, XML and JSON.
  • The Locker Project - an open source, JavaScript-based, PDS with a centralized underlying attribute store that exists on a person's personal computer as well as an API to support local applications.
  • openPDS/SafeAnswers - openPDS/SafeAnswers allows users to collect, store, and give fine-grained access to their data all while protecting their privacy.
  • Higgins - Higgins is an open source project dedicated to giving individuals more control over their personal identity, profile and social network data.
  • ID Hole - a dynamic and commercial consumer PDS that allows for the storing of personal data and the dynamic sharing of that data with other parties.



For-profit EnterpriseEdit

Non-profit PersonalEdit

  • Mydex - empowers individuals to manage their lives through convenient, trustworthy access and control of their personal data and how it is used by them and others. This is achieved through interoperable API-based components for identity, consent and personal data management.
