Facebook get latest post?

Question

Facebook

Hello!
I started working with Facebook, you basically need to get the latest post from your page. Is it necessary to make an application for this? But I did it, but I can’t publish it, it asks for this crap "Privacy Policy URL", but why is it in an application where no data from the user is needed? And out of the corner of my eye I saw that tokens are given for a while. Is it possible to do something permanently? You have to keep an eye on it...
