Cell Networks

We export both a daily snapshot of the entire cell network collection as well as hourly differential updates. File names contain either the word diff or full to specify their type. The full cell export is limited to those cell networks whose position has been confirmed in the last 12 months.

WiFi Networks

The combination of a MAC address and a location is considered personal data in some jurisdictions, as it contains data about the owner of a WiFi network. The collection of this data is legal as long as an effective opt-out mechanism like the one we follow is provided. Lookups of individual WiFi records are prevented by the service by requiring a combination of two matching nearby WiFi networks in queries.

We do not share data about WiFi networks. Sharing such data could expose personal data and make it possible to track the movements of WiFi networks over time.

Observations

In addition to the aggregate network data, the service also gathers the raw observation data these aggregates are based on. While we do not store any individual user token with the observation data, the data itself contains plenty of unique characteristics, locations and timestamps that would allow someone to track the movements of the people contributing observations to this service.

We have therefor chosen to use a conservative approach and do not make the raw observation data public.
