So, the app works fine, all the correspondence is hidden. all sms, photos and videos that do not need to show unnecessary people also hidden.
I had to delete the app at one point due to the change of phone, it turned out that some cleaning appx deleted some hidden leo privacy guard files as garbage, so I wrote them to the support
[email protected] and normally resolved everything. i recommend it. and now, after reading the reviews above, i realized that i was stupid, not blocking some of their applications, and leo can do it! thanks to those who wrote!
