Here's what they said years ago:
"The short answer- yes, it’s safe to use myPill, we’ve always placed user privacy as our #1 priority.
Let’s start with what’s stored on our server, only two things - forum content and data backup, only if you have the option enabled in the app’s settings.
You can always request your data to be erased, after a quick authentication there will be nothing on our servers, if so you desire.
The backup store is packed and encrypted in our database, but in any case we would not allow any org or gov to access it. Would rather delete it and pull myPill out of such countries."
