RBR40 and Armor subscription?

[RedCab]

Purchased RBR40 several months ago from Best Buy. (BTW, why isn't RBR40 in any of the choices?) 

In the app, Armor shows it's activated yet I can't remember ever subscribing to a term or making payment.

So my question is: Is the Armor in use on my router (1) Free, forever or (2) Free for now but I'll be asked to subscribe later (at cost) or (3) I paid for it and just can't remember doing so (doubtful!)

Thx.
