Pan-European Privacy-Preserving Proximity Tracing

Pan-European Privacy-Preserving Proximity Tracing
(PEPP-PT) makes it possible to interrupt new chains of SARS-CoV-2 transmission rapidly and effectively by informing potentially exposed people. 
We are a large and inclusive European team. We provide standards, technology, and services to countries and developers. We embrace a fully privacy-preserving approach. We build on well-tested, fully implemented proximity measurement and scalable backend service. We enable tracing of infection chains across national borders. 

Proximity Tracing YES, Giving Up Privacy NO!

The PEPP-PT system is a larger software system with many individual components. 

PEPP-PT wants to continuously improve its approach and therefore needs to be open to ideas that pursue common goals. This in particular includes any ideas which adhere to the goals of supporting: roaming/interoperability (“Pan European”), adheres to GDPR (“Privacy-Preserving”), and delivers epidemiological data to fight the pandemic (“Proximity Tracing”).

In accordance with the recently published EU Toolbox, PEPP-PT currently considers two privacy-preserving approaches: “centralized” and “decentralized”, and continues to be open for further ideas for improvement that support PEPP-PT goals.



PEPP-PT was created to assist national initiatives by supplying ready-to-use, well-tested, and properly assessed mechanisms and standards, as well as support for interoperability, outreach, and operation when needed.


The PEPP-PT mechanisms will have these core features:

  1. Well-tested and established procedures for proximity measurement on popular mobile operating systems and devices.

  2. Enforcement of data protection, anonymization, GDPR compliance, and security.

  3. International interoperability to support tracing local infection chains even if a chain spans multiple PEPP-PT participating countries.

  4. Scalable backend architecture and technology that can be deployed with local IT infrastructure.

  5. Certification service to test and ensure local implementations use the PEPP-PT mechanisms in a secure and interoperable manner.

  6. Our reference implementation is available under the Mozilla License Agreement.

To find out more about the additional services we offer to support infrastructure and installation campaigns to enable country-specific applications, please download our Manifesto. 


The virus has spread quickly and knows no political boundaries. To bring it under control, we must act in the same manner; speed and international cooperation are essential to protect health, privacy, and the economy.

Find out more about our view of the current situation and why we believe proximity-tracing is the appropriate solution to resuming a normal life, opening our borders, and restarting the economy. 

We invite all countries to participate and use what we have to offer. We are stronger together against SARS-CoV-2. Please contact us if you are interested in using our services or contributing. 



We are establishing a partner management team to help you get going quickly.


As a partner, you will:

… have access to our services and mechanisms.

… have access to our documentation and the source code of a reference implementation.

… take part in the inter-country exchange that will make our lives global again.

… provide feedback on the technical design.

… encourage your country to support PEPP-PT development and deployment.

… obtain certification for your implementation through PEPP-PT and thus inherit our privacy and security certifications and credentials.

… provide your national cyber-security, data protection, and health agencies with a solution that saves the effort of building certified services from scratch.

… receive planning and financial aid for installation and trust campaigns in your country.

… receive planning and execution aid for integrating PEPP-PT into your country’s strategy.



You can either implement PEPP-PT directly using the provided app/trust service reference implementation and add country-specific aspects


Integrate PEPP-PT technology into an existing solution through the modules in our  services.


Please get in touch.

We welcome you on board. 



PEPP-PT is an organization that will be incorporated as a non-profit in Switzerland. PEPP-PT was created to provide a solution to this crisis that adheres to strong European privacy and data protection laws and principles. The PEPP-PT technical mechanisms and standards fully protect privacy while taking advantage of the possibilities of digital technology to maximize the speed and real-time capability of national pandemic responses. Our goal is to make this technology available to all countries, managers of infectious disease responses, and developers as quickly and seamlessly as possible.


The PEPP-PT team, which as of 31st March 2020,  has more than 130 members across eight European countries, includes scientists, technologists, and experts from well-known international research institutions and companies. We have expertise in communication, psychology, epidemiology, proximity tracing, security, privacy, encryption, data protection, application development, scalable systems, supercomputing infrastructure, and artificial intelligence.

The PEPP-PT team started this effort because it must be done. We hope you value our efforts to restart social and economic life and are willing to support them. A donation would help keep our efforts going for the long term and make it possible to support many countries in setting up a proximity-tracing-based, privacy-protecting pandemic response. 


PEPP-PT is purely funded by donations. It is a non-profit organization and completely transparent. Our strict guidelines preclude any influence from donors.


As the formal organization is not yet established, we cannot yet provide links for making a donation or for downloading the guidelines for a donation. Please sign up below if you would like to be informed when you can support us.
