Hello @murnialay
First of all, thank you for choosing our products. We really appreciate this.
Secondly,
Our plugin try to make the print screen function more difficult but it will not prevent it 100%, simply using any print screen software you can go over any script and take a screenshot for anything you want
Because of this, we add a watermarking feature to watermark images and this is the best way for image protection
Making content-stealing very hard is the main goal for our plugin (but we cannot guarantee 100% protection).
We are sure that you don’t waste your money when you put an expensive door to protect your home!!
Although some thieves can break it and steal your home content!
In other words, we try to make the stealing process more and more difficult. Not impossible but a lot of difficulty means fewer thieves.
(Snag-it software) as an example, and other external software are out of control because the plugin work inside the browser but the external software work from your system
Also, we try a lot to make print screen protection working on Mac but we still face a lot of problems (note: we don’t say that we provide protection over mac and you can search our product page here)
Thank you
