How to uninstall an application?

Question

Android

Good afternoon. Please help me remove lock screen app. It does not work in the standard way, the buttons are inactive. It's very annoying when, when wifi is turned on, the service of this application is launched, which is accompanied by the appearance of a blank screen (permission to draw over other apps). It is possible that this is some kind of spy. I don't know what I was thinking when I installed it, because
full network access
find accounts on the device
read + write the content of your USB storage
read your web bookmarks and history
read phone status and identity
clearly indicate something more than just a screen lock.
