No user accounts, by design
The thing that F-droid are getting right here is &quot;if we don&#x27;t track you, you have privacy from us&quot;.<p>But privacy is not secrecy.  If f-droid tracked my every waking move, and then just never bother to look at that data, I would  still have privacy from them.<p>What they are doing here is a form of guaranteeing their future good behaviour.  Which is nice, but there are other methods.  For example I am happy to announce my plans to <i>not</i> rob a bank.  But there are means in place to ensure I do not - At least not twice.<p>So while it is nice to find ways to avoid having user accounts at all, most hospitals will have to have other means to keep their users privacy.<p>Most of the time we are going to need to rely on regulation, where PII data (which lets face it is 98% of all data) will both legally and culturally have to be protected at levels hardly dreamed of today.
