Wow! So many 1 ⭐ reviews. I've been using this app for about 3 years and I only get pop ups if I haven't actually read through the options on the homepage and forgot to stop receiving the pop up. Usually after an update you have to update the notifications that you want and select the ones you don't. After switching providers the cleaner that I had been using forever wasn't available. So I did my research and chose this one. If it's not for you be sure to delete before trying new apps.

While it does a decent job of protecting my phone, it has the extremely annoying habit of kicking me out of games I'm playing just to give me notifications that I don't need. This has caused me to lose the game on many, many occasions. I will probably be removing this app from my phones and tablets and going with less intrusive and less interfering apps instead.

I've been getting really annoying pop-up ads that appear every two or three minutes I can't even turn on my phone without having a pop-up add it's very annoying and instead of just telling us to email you how about you actually try to fix this this app is terrible, I recommend CCleaner witch doesn't bombard you with adds and their profiting off of it because they're showing regular commercial ads too. you can fix by going into settings and type in apps and look from a blank wite icon, delete it.

Our Promotion Policy clearly prohibits invasive alerts promoting our app. Learn more: psafe.com/promotion-policy - It has been common for users who download apps out of Google Play or access downloads sites to report this situation. Uninstall unknown/blank apps, clear your browser cache and, if it persists, send screenshots support@psafe.com
