We are entrepreneurs, activists, academics, listed corporations, public agencies, and developers. For years, we’ve been using different words for what we do – MyData, Self Data, VRM (Vendor Relationship Management), Internet of Me, PIMS (Personal Information Management Services) etc, while sharing a common goal: to empower individuals with their personal data, thus helping them and their communities develop knowledge, make informed decisions, and interact more consciously and efficiently with each other as well as with organisations.

Together, in recent years, we have formed a network whose participants share experience, develop common projects, meet at the MyData conference, and take part in collective endeavours towards a human-centric approach to personal data.

It is now time to take this work out in the world and prove its potential impact on individuals, society, and the economy. Today, we believe it is time to publicly assert the values that drive us – and call on those who share those values to act upon them. Join us in reversing the paradigm of personal data. Join us in creating the MyData movement.



As the importance of personal data in society continues to expand, it becomes increasingly urgent to make sure individuals are in a position to know and control their personal data, but also to gain personal knowledge from them and to claim their share of their benefits.

Today, the balance of power is massively tilted towards organisations, who alone have the power to collect, trade and make decisions based on personal data, whereas individuals can only hope, if they work hard, to gain some control over what happens with their data. The shifts and principles that we lay out in this Declaration aim at restoring balance and moving towards a human-centric vision of personal data. We believe they are the conditions for a just, sustainable and prosperous digital society whose foundations are:

  • Trust and confidence, that rest on balanced and fair relationships between people, as well as between people and organisations;
  • Self-determination, that is achieved, not only by legal protection, but also by proactive actions to share the power of data with individuals;
  • Maximising the collective benefits of personal data, by fairly sharing them between organisations, individuals and society.


Our overriding goal is to empower individuals to use their personal data to their own ends, and to securely share them under their own terms. We will apply and practice this human-centric approach to our own services, and we will build tools and share knowledge to help others do the same.


In many countries, individuals have enjoyed legal data protection for decades, yet their rights have remained mostly formal: little known, hard to enforce, and often obscured by corporate practices. We want true transparency and truly informed consent to become the new normal for when people and organisations interact. We intend access and redress, portability, and the right to be forgotten, to become “one-click rights”: rights that are as simple and efficient to use as today’s and tomorrow’s best online services.


Data protection regulation and corporate ethics codes are designed to protect people from abuse and misuse of their personal data by organisations. While these will remain necessary, we intend to change common practices towards a situation where individuals are both protected and empowered to use the data that organisations hold about them. Examples of such uses include simplifying administrative paperwork, processing data from multiple sources to improve one’s self-knowledge, personalised AI assistants, decision-making, and data sharing under the individual’s own terms.


Today’s data economy creates network effects favoring a few platforms able to collect and process the largest masses of personal data. These platforms are locking up markets, not just for their competitors, but also for most businesses who risk losing direct access to their customers. By letting individuals control what happens to their data, we intend to create a truly free flow of data – freely decided by individuals, free from global choke points – and to create balance, fairness, diversity and competition in the digital economy.


Please note: “Roles” are not “Actors” an individual or organisation may fulfill one or more roles at once.



An individual that manages the use of their own personal data, for their own purposes, and maintains relationships with other individuals, services or organisations.


A data source collects and processes personal data which the other roles (including Persons) may wish to access and use.


A data using service can be authorised to fetch and use personal data from one or more data sources.


A Personal Data Operator enables individuals to securely access, manage and use their personal data, as well as to control the flow of personal data with, and between, data sources and data using services. Individuals can be their own operator. In other cases, operators are not using the information itself, but enabling connectivity and secure sharing of data between the other roles in the ecosystem.


In order to produce the shifts that are needed for a human-centric approach to personal data, we commit to working towards and advocating the following principles:


Individuals should be empowered actors in the management of their personal lives both online and offline. They should be provided with the practical means to understand and effectively control who has access to data about them and how it is used and shared.

We want privacy, data security and data minimisation to become standard practice in the design of applications. We want organisations to enable individuals to understand privacy policies and how to activate them. We want individuals to be empowered to give, deny or revoke their consent to share data based on a clear understanding of why, how and for how long their data will be used. Ultimately, we want the terms and conditions for using personal data to become negotiable in a fair way between individuals and organisations.


The value of personal data grows exponentially with their diversity; however, so does the threat to privacy. This contradiction can be solved if individuals become the “hubs” where, or through which cross-referencing of personal data happens.

By making it possible for individuals to have a 360-degree view of their data and act as their “point of integration”, we want to enable a new generation of tools and services that provide deep personalisation and create new data-based knowledge, without compromising privacy nor adding to the amount of personal data in circulation.


In a data-driven society, as in any society, individuals should not just be seen as customers or users of pre-defined services and applications. They should be considered free and autonomous agents, capable of setting and pursuing their own goals. They should have agency and initiative.

We want individuals to be able to securely manage their personal data in their own preferred way. We intend to help individuals have the tools, skills and assistance to transform their personal data into useful information, knowledge and autonomous decision-making. We believe that these are the preconditions for fair and beneficial data-based relationships.


The portability of personal data, that allows individuals to obtain and reuse their personal data for their own purposes and across different services, is the key to make the shift from data in closed silos to data which become reusable resources. Data portability should not be merely a legal right, but combined with practical means.

We want to empower individuals to effectively port their personal data, both by downloading it to their personal devices, and by transmitting it to other services. We intend to help Data Sources make these data available securely and easily, in a structured, commonly-used and machine-readable format. This applies to all personal data regardless of the legal basis (contract, consent, legitimate interest, etc.) of data collection, with possible exceptions for enriched data.


Organisations that use a person’s data should say what they do with them and why, and should do what they say. They should take responsibility for intended, as well as unintended, consequences of holding and using personal data, including, but not limited to, security incidents, and allow individuals to call them out on this responsibility.

We want to make sure that privacy terms and policies reflect reality, in ways that allow people to make informed choices beforehand and can be verified during and after operations. We want to allow individuals to understand how and why decisions based on their data are made. We want to create easy to use and safe channels for individuals to see and control what happens to their data, to alert them of possible issues, and to challenge algorithm-based decisions.


The purpose of interoperability is to decrease friction in the data flow from data sources to data using services, while eliminating the possibilities of data lock-in. It should be achieved by continuously driving towards common business practices and technical standards.

In order to maximise the positive effects of open ecosystems, we will continuously work towards interoperability of data, open APIs, protocols, applications and infrastructure, so that all personal data are portable and reusable, without losing user control. We will build upon commonly accepted standards, ontologies, libraries and schemas, or help develop new ones if necessary.


  • Sign the Declaration, as an individual and/or as an organisation. This Declaration is written in the future tense: if your organisation isn’t quite there, but is committed to moving into this direction, it should still sign it!
  • Comment on the Declaration. This Declaration will evolve over time, based on your ideas and practical experience. There will be an initial review after 6 months.
  • Use the Declaration to further your own projects and intentions. Base your trust framework, or your terms of services, on it. Use it to lobby and convince clients, partners, stakeholders etc.


This Declaration of Principles draws upon many sources of inspiration, the most significant ones being:


The MyData Declaration emerged out of the “European PIMS (Personal Information Management Services) Community” which met in Brussels (November, 2015), Paris (April, 2016), Helsinki (August, 2016), London (December, 2016) and Berlin (March, 2017). More specifically, the Berlin meetings produced a memorandum that stated two complementary goals:

  1. To establish a MyData Global Network as a legal entity
  2. To start by developing a common set of principles for the human centric personal data

This MyData Declaration is the response to the second goal.


This initial version (1.0) of the Declaration was written by three persons who are all heavily involved in the PIMS Community as well as in organising the MyData Conference:

  • Antti “Jogi” Poikola (Finland), researcher at Aalto University and founding member and former chairman of the Open Knowledge Finland association, also the main organizer of the MyData Conference and leading author of the Finnish MyData white paper.
  • Daniel Kaplan (France), cofounder and scientific advisor to Fing and France’s MesInfos project, member of the MyData Conference’s core team and core contributor of the MesInfos Self Data Charter.
  • Tanel Mällo (Estonia), head of Research Administration Office at Tallinn University, lead of MyData Estonia network, member of the MyData Conference’s core team, in charge of MyData 2017’s Tallinn events.

This initial drew inspiration from a thorough reading of 20 existing charters and statements of principles, and was prepared by a workshop in Berlin which organised and prioritised the central ideas.

A draft version was sent for comments to the Founding members of the MyData Global Network, as well as participants to the Berlin workshop. It received more than 90 comments. After a 2-weeks comments period, the current version of the Declaration was fixed in its current state.


This Declaration is the founding text of the “MyData Global Network” (whose name might change) and will be managed by it as soon as this organization is more formally established.

The published version of the declaration is now stable and can be signed by individuals and organisations.

In the future, new versions of the text will certainly need to be written based on experience, as well as on the advancement of technology, markets, uses and regulations. A set of issues has explicitly been left open for future discussions.

Also, a discussion is already underway as to how selective and binding this Declaration should be, so that organisations can’t just sign it without actually committing to implementing it. We want the Declaration to be open for all to sign, but we also want it to herald a significant change in the “normal” way in which all organisations handle personal data.


  • Sign the Declaration, as an individual and/or as an organisation.
  • Use the Declaration to further your own projects and intentions. Base your trust framework, or your terms of services, on it. Use it to lobby and convince clients, partners, stakeholders etc. And please, let us know, so we can all benefit from your experience!

The MyData Declaration’s future versions will be produced in an open manner and everyone is welcome to contribute. The conversation takes place on the MyData Declaration mailing list. This list is currently facilitated by Antti “Jogi” Poikola, Daniel Kaplan and Tanel Mällo. A list of issues left open in the v. 1.0 of the declaration can be accessed here
