Yes, it collects your email when you install. This lets me send a couple onboarding messages and determine what plan you are on. There's more info in the (human readable) privacy policy.

When I started this project I wanted the onboarding experience to be as simple as possible, i.e. no annoying sign up stage. I wondered whether this approach would lead to lots of questions like yours: in fact, I think less than 5 people have asked about this since 2015. My sense is that, on balance, most people benefit from the "install = sign-up" flow.
