Pinegrow offline activation

Hi all,
I have a request please answer from admin side only.
After purchasing pinegow, how we can activate it offline? After searching in google I found a link . But that link not appears genuine. Because it is not https. Is it the correct link? or is it a spam link? If you mention correct link in site itself it will be good and useful for your customers.

Small requst to all members in the forum : let the admins to answer this question, so there won’t be any confusion in the answer.

Thank you.

Seems very legit to me… there was a link and it gave me back my licenses. How could it not be (technically) as it’s still

I do have a bone to pick in another post.
