During our beta testing, we may collect information about your phone and the state that it was in when the app crashed to help us fix the problem, but only because Apple and Google do this on our behalf.
Other than that, we have no interest in your data. We promise to never share your data with other companies no matter how much they give us, because we do not have access to any of it. We don't even run a server, other than this marketing site (that's expensive!). Instead all the data is stored locally on your device and can be backed up to your secure DropBox account.
Your data is your data. We wouldn't want anyone to know what we've been doing, and we think you probably agree.
