I think location histories via GPS do not give you much precision unless the device actively polls the GPS, which kills the battery, and even then not on many devices. There are many issues with bluetooth but devices can kinda run it in the background without draining the battery too badly.

Privacy oriented individuals might choose not to use the app at all it features like this exist. Even if contact history (tokens) would be in the mobile phone, a user could very likely identify the contacts using the location history as a logbook.

The app does not aim at identifying locations that may be dangerous due to concentration of infected cases. This is a design decision. We limit the purpose of the application to the two goals described in the White Paper (notifying at-risk users, and provide epidemiologists with data to understand the disease). This enables us to collect and process very little data. In particular it avoids that we collect location data, which are highly sensitive and very hard to publish in a privacy-preserving way.
