The guidelines on geolocation and other tracing tools in the context of the COVID-19 outbreak aim to clarify the conditions and principles for the proportionate use of location data and contact tracing tools, for two specific purposes:
1.    using location data to support the response to the pandemic by modelling the spread of the virus in order to assess the overall effectiveness of confinement measures;
2.    using contact tracing, which aims to notify individuals who may have been in close proximity to someone who is eventually confirmed as a carrier of the virus, in order to break the contamination chains as early as possible.

The guidelines emphasise that both the GDPR and the ePrivacy Directive contain specific provisions allowing for the use of anonymous or personal data to support public authorities and other actors at both national and EU level in their efforts to monitor and contain the spread of COVID-19. The general principles of effectiveness, necessity, and proportionality must guide any measures adopted by Member States or EU institutions that involve processing of personal data to fight COVID-19.
