I'm glad you have discounts and promotions. That's what email is for. I have unchecked every friggin box dealing with notifications and I still get promo announcement popups from CCleaner that take up close to a quarter of my 27" monitor.
HOW DO I STOP THEM??? I DON'T WANT THEM. I DON'T CARE ABOUT THE OFFERS. PUT THE OFFERS ON YOUR WEBSITE, SEND THEM AS EMAIL, BUT DO NOT INVADE MY OPERATING SYSTEM.
My time is valuable. I don't like to be interrupted from actual work to have to close the stupid, unwanted, uninvited popup.
If it's not possible to exclude this feature from CCleaner, I'll just find another application--which would be a shame since I've been using CCleaner since some of its earliest versions.
