Offline VIP

Hello,

I purchased a SIYUAN VIP account and I also use it on a PC that is permanently without internet access for security reasons. Unfortunately, I've discovered that some of the VIP account features don't work on this offline PC, probably because it's impossible to log in to the SIYUAN account on it.

I would like to ask if there is any solution to this situation. Is it possible to activate the VIP features offline in some way, such as through offline activation or another method?

Thank you for your help and any suggested solutions
