Tech giants are joining the fight against coronavirus — and in the process, they're giving us a look under the hood at some of the user data they've been tracking all along.

Facebook, Google, and Apple have all released maps and dashboards in recent weeks powered by information from millions of users that show how COVID-19 is spreading. Each visualization reflects the unique type of data that each tech company is poised to collect from users.

Google and Apple both released tools that show people's mobility in specific areas and how much it's decreased amid government-mandated shutdowns. In both cases, the companies gleaned this data from people using Apple Maps and Google Maps, as well as location data from iPhone and Android users, respectively.

Facebook published a map showing how many people are reporting COVID-19 symptoms in each county in the US, gathering data by surveying millions of Facebook users. This week, the company also released a mobility dashboard that aggregates information on people's movements from a conglomerate of private companies, as well as public resources like satellite imagery and census data.

In all cases, the tech giants insist that the data is anonymized and can't be traced back to individuals. Privacy is also a central focus of forthcoming contact-tracing tech from Apple and Google that would use Bluetooth to alert people who come in contact with COVID-19 without tracking their location.

Here are all of the COVID-19 maps, charts, and dashboards from major tech companies made from aggregated user data.
