We use Fabric to collect crash reports of the app. This includes information like your phone type and iOS version. There is a unique id on those crash reports, but we cannot tie that unique id to any particular person.
In the current version, when you tap the '+' button to add a new friend or family member, we call an Apple api to show a list of contacts from your Contacts application. For the contact that you choose, we request the following information:
We then ask Apple servers to convert that address to a latitude / longitude, and use that to request the weather for that location from the Dark Sky weather api.
All of this data is cached locally on your iOS device, and none of it is logged or sent to any server, besides the latitude / longitude to Dark Sky.
We do no other tracking of you as a user or your data.
