The app doesn't collect or share any user data. This is also true for the associated sites, including the image gallery.
Note, however, that if you browse the Net with Web Wallpaper, the sites you go to might collect / share some data about you, as much as they can gather without any support from the app. This is generally true for any browser and is something that's out of the control of Web Wallpaper. The data such sites can collect about you is very limited.
Also important to know, the app has no special permissions (for instance it cannot read the hard disk), this can be checked. So it's even clearer that it's safe for privacy.
