We take the privacy and security of your medical information very seriously, which is why we updated our app to lock automatically whenever you stop using it for more than a minute. You can unlock it quite simply with the use of a fingerprint,  face scan or a chosen PIN code. This is the same system that is used in apps for mobile banking which most people are familiar with.  

Of course, all other security features such as data encryption, not sharing any components with other applications, or "polluting" the source code before the new version is released are still in place to protect your data.
