Very nice equipment, software patronized something

The device itself is small, handy, easy to use, looks nice and I measure now for a number of weeks with the first battery charge. The operating noise during inflation of the cuff is audible, but not exceptionally loud.
What should be noted is that the values ​​on the phone with the date and time of the meter are stored. You have this set incorrectly, you wonder later why show up on the phone no data.

What bothers me is the app / cloud:
I've had enough perfectly when I readings on my own device, on which I can still share as needed with the doctor or to email him. Although everyone assured me that all this is absolutely safe: I will not be stored on the computers of the manufacturer's values. I have no discernible benefit thereby. Bypassing I could not, the registry has annoyed (again any password the same way and has to look so and I but then forget again or must be written in the now endless list), also connects my phone after each Trade shows over the Internet to the server.
It would be desirable software that only runs on my computer and a simple function to export the data as an Excel spreadsheet or an image with graph.
