Internet Download Manager 1 year license OR Lifetime License

[neutrinos]

Hi All,

I want help in finding out whether the Internet Download Manager license is 1 year license OR Lifetime License .

I activated my IDM 1 year license 3-july-2015.

and 

If it is 1 year license then it should have stopped as Full License; But now  even after 1 year it is activated.

SO it is continuing activated in over 12months ...going into 14 th month....

So Is it lifetime license ???

How to find out the time limit of IDM license  ?

Is IDM Lifetime License has specific letters in license which can denote it is lifetime license.

I doubt If I ask  Tonec Inc.they might disable the license.

How do I ask the Company about validity of License ?
