-What platforms are supported (it looks like MacOS from the demo video, but I couldn't find whether there is an iPad or iOS app, or whether it supports Windows and Android; access and syncing to a mobile device is very important from my perspective as a user)
-Whether it's possible to "Get started" without using the Google sign-on; I typically avoid using Google to sign in, and prefer traditional registration with an email and password
-A clear and straightforward Privacy Policy, which would be a plus. You have one linked at https://emery.to/privacy/ , where you did write that users have the right to: "Restrict the processing of their Data. Users have the right, under certain circumstances, to restrict the processing of their Data. In this case, the Owner will not process their Data for any purpose other than storing it. [...] Have their Personal Data deleted or otherwise removed. Users have the right, under certain circumstances, to obtain the erasure of their Data from the Owner." The "under certain circumstances" seems vague, and I'm unsure what that means in practice.
However, you have to scroll down quite a bit, and I'm not comfortable with the use of Google Analytics. I'm not necessarily against using the app just due to privacy reasons (though other users might be), but I wish I could find out in advance of signing up, how much data collection I could opt out of before signing up.
