Can I download the entire raw database?
No. While we try to make the service as open as possible, the underlying data contains personally identifiable information from both the users uploading data to us and from the owners of WiFi devices. We cannot publicly share this data without consent from those users.
According to our current policy we can and intend to publicize the aggregated data set of cell locations.
What license is the data going the be available under?
See above. For the data we can publish our current preference is either CC-BY-SA version 4 or a combination of the Open Database License (ODbL) & CC-BY-SA 3.0 as used by similar projects.
Did you talk to project X?
We have contacted and are in talks with a number of existing projects. See a list of the projects at CloudServices/Location/Bootstrap for projects and companies known to us.
Also in case of a positive response from these projects we have not been able to make any progress until now, all their ideas and suggestions are still under Mozilla-internal discussion.
Is the app available in the play store?
The stumbler app is not yet in the play store. You need to manually install it from our release page. But the app contains an integrated update mechanism, so it'll stay current once installed.
Do you collect the SSID from WiFi networks
The SSID is the clear text name you see when connecting to any WiFi. In addition each WiFi has a BSSID (which is often the MAC address of the WiFi device). The BSSID is a unique identifier and as such sufficient to distinguish WiFi networks for the purpose of the location service. We follow the general principle of "only collect what you need" and as such don't collect SSIDs.
