Too bland. Not to mention when I first started using it, it pulled 80 notifications of leaks from years ago that are done and fixed. Not just that, but about 80% of the leaks say "Unknown" when it involves a URL. But it's security features seem helpful so far. I just don't understand why everything you add to protect needs to be verified. It makes no sense to verify we want to keep an eye on something to make sure it's not leaked. I added more info but it didn't show up either.

Having every device's status and an on demand scanner are nice. But this app's constant complaining with non-dismissable notifications and in-app alerts for disabled features is unacceptable. Web protection is of no use to me, and no amount of nagging will get me to enable it. The feature doesn't even work with Firefox, so having it enabled would be wasting battery/resources on a pointless background process.

Disappointing for 2 reasons. To start, the app mysteriously turns off "Web protection" several times a week. I've yet to figure out what causes this. And it looks to me the notification icons don't differ between active and inactive. I've emailed the developer address here and turned in a feedback form with diagnostics through the app. To date, I've received no correspondence from Microsoft. There have been 2 updates, but neither have resolved my issue. As I write this, I'm using version 1.0.3911.0301
