Locker app has broken links

As is pointed here the links for the locker app are broken

Does the f-droid servers hold a copy of the repo clone to make it available?
Edit: yes they do

I installed this app today and it works perfectly. I wanted to propose some improvements

What does f-droid do in this situations? keep the app until it does not work in recent android versions?
