Security and integrity of apps and data

Security and integrity of apps and data

Hello, I'm Darío Blanco from Argentina, and have a query concerning to the security of applications and data. Yesterday the application was fine and today appeared two new criteria en two views that we never didn't set.
Is that normal? What are there about the integrity of apps and data?
We have a free user, because we are testing your system (we think test at least 60 days). Is that problem happening because we are free users? Can we save that problem next time?

Excuse me for my English. The services and apps of your web site are awesome. I hope that you understand me.

Thanks and greets.

Darío
