Problem with app security when I share it

[jean-mi]

Hello,

I share my application with another user.
I selected: view definition (to protect access to the definition) and just "User".

As you can see in the image below, it doesn't have access to columns etc... that's fine

But he can copy the application and then recover the data and the definition in the copy. He can therefore circumvent the security rule put in place.

Something escapes me... 

How to prevent application copying?

thanks for reading
An idea ?
