Fantastic to see @NHSX being open about how they are bringing together data and working with the private sector to help inform the UK's response to Covid-19. Thank you @matthewsgould @IndraJoshi10!
It's also great to see this commitment to making the underlying code, and the non-personal / aggregate data and metrics gathered available as open data. Doing that will enable others (looking at @jburnmurdoch here) to build dashboards and visualisations for the public. 
Not quite so happy with this bit: the term "anonymous" usually covers a multitude of sins. It is usually wrong to claim people *cannot* be re-identified if the only anonymisation process is pseudonymisation. Better to say risk is minimised through strong access controls.
