Please do not feel offended by my words but I would never ever use a service like this.

The question in most cases in my opinion is not "will there be a data breach?" but when it will occur. Leaving this kind of data on some servers of some company just opens the door for patients to be extorted etc. in the future.

I like the idea of apps and computers helping us with problems like that but in our world services and devices are just not trustworthy enough for my taste.

Maybe a desktop app on a device that has no internet connection would be a reasonable alternative.

I wish you good luck with your business though and keep my fingers crossed that somehow your data remains secure.
