Safety overview

Status: Mostly safe

pap.er is a wallpaper utility for macOS, so changing your desktop background and downloading wallpaper content are normal parts of how it works. It may access network resources to fetch wallpaper images and can store downloaded images or app data locally for browsing and rotation. That behavior is ordinary for this type of app. If you no longer use it, removing it should mainly affect your wallpaper library inside the app and any convenience features such as scheduled rotation.

Recommendation: Keep pap.er if you use it to manage desktop wallpapers or automatic background rotation on your Mac. If you do not use those features, you can remove it with little impact beyond losing its wallpaper library, saved settings, and rotation tools.
