The extra insidious and harder to take away the model of supercookies come from web service suppliers (ISPs).

If every little thing goes based on plan, you must see one thing that appears like this:
Right here you possibly can inform Flash to not retailer any cookies sooner or later. Simply drag the slider all the best way to the left (“None”), after which choose “By no means Ask Once more”.

Merely put, there isn’t a solution to take away an ISP’s UIDH supercookies. To take action, you’d need to someway achieve entry to the ISP’s servers and delete your units’ distinctive knowledge from there. Given the authorized impossibility of that, your only option is to stop ISPs from correctly monitoring your units’ exercise.
