We have been following that issue pretty closely. As in many cases, when you roll out something quickly in the midst of a pandemic, it's not always the best way to make good policy. I think we have learned a lot about the use of contact-tracing apps and what are appropriate ways to safeguard privacy and data more effectively, through using data localization, through making sure that the process is transparent and that there are limits to how long data can be saved. All sorts of measures need to be in place when that type of technology is rolled out. Unfortunately, in a few places, we have seen the consequences when they haven't been in place.
Therefore, I do think those lessons learned really need to be put in place. There's also such a diffusion of the different contact-tracing apps and the ways they are being used that it would be good to have some cross-fertilization of that learning across contexts to make it easier for people to ensure that this technology is something they can rely on in terms of their privacy and their rights.
