Thank you to everyone, expect better security with the next updates.
Your administrator doesn't even respect his own forum's rules, lol.

Oh, and
@darkbeast expect your license to be fully cancelled

Hey AltumCode!
Before I say anything else, all your scripts are available - nulled 100% working and updated. As most of other developers scripts are. I won't even start talking about Wordpress themes and plugins, because... oh boy.
Does that mean we use it for profit or client work? Maybe some users here yes... others not really.
In my case this was very simple, I had to show to a client a script & landing page in working conditions (sandbox payments and all). How do you expect someone to spend 499$ on a script, to find no use after that and that we cannot get a refund (even if you cancel the license code)?
In case the client liked it, the license would be bought and passed to him. Simple as that...
Guess what happened? The client ended up by choosing QR Menu Maker script available on CodeCanyon because it has a funny QR Builder. 125$ extended license (way cheaper btw) and the site is up and running making him some profit. I also did my profit from the work, and the developer 125$ minus what Envato charges. All happy in the end of the day with clients getting auto updates and my hand are free for other projects.
The script is good and I personally like it, I would show this script first to a client then any other script available, but don't expect it to be selling like cupcakes, with your refund policy, selling it on GumRoad only, 499$ extended, no trial - there are multiple options that are way less expensive that have the same functionality or even some more.
Go ahead and cancel my License, don't make the mistake and cancel someone else key and piss them off! If I was really dishonest I would just do a chargeback on the card, used the nulled version and call it a day.
No refund policy at all on Gumroad, "Unlimited Users & Stores" on the regular license etc induces the client that has payment functions etc, just some points for you to also think about to protect yourself in the future.
Basically you can cancel all the licenses you'd like, I would get my money back and you get minus 69$ for me it's even better. When you release a new version someone will just buy it again, chargeback because there's some flaw on the policy and someone will null it somewhere on the internet.
Now I should go write a Bible! Peace!
