Security related to the third party account statements and statistics services ?

I like to take use of third party services for advanced account statements and statistics. But I don't know whether these services are safe and free from security risks, malware and forex scams.

I like to use this service http://www.mt4i.com/ from MT Intelligence. I have used this in my demo account and it seems to be ok, but I'm a bit afraid or cautious to use it in my real account.

Does anybody use this service in real account ?

I searched a lot about the mt4i.com from the Internet with different keywords and I didn't found anything strange. Instead I found that many websites are using their services on the real accounts. I think that I was a bit paranoid.
