Is IP geolocation allowed with all the latest privacy concerns?

Hi,
I'm developing a game with a strong social aspect.
In the current setup, In the onboarding process if the user hasn't yet registered I am using the country of the ip address as a placeholder until the user register and provide his/her real country( or fake, I cannot verify that).
Am I allowed to do that or there are some privacy laws that forbid this?

 

not ones that apply to all countries.

so to work out which laws applied, you'd have to check what country the user was in and....

catch 22.

 

This requires GDPR consent at the very least, I believe.

 

All these new privacy law are a nightmare. I checked the facebook integration I developed a couple of years ago and now most of the permission require approval from facebook, back to square one...

 

Well, it is rather simple: just don't store anything about the user until they give permission to do so. No placeholders and alike (other than anonymous data). This should have been the default at the begin with in my humble opinion.
