Translation guide
Expressing that you do not care at all about something, showing complete indifference or lack of concern.
To say that something does not matter to you at all, or that you have no interest or concern.
A direct and neutral way to say you don't care at all. Suitable for most situations.

I don't care at all what he says.
Literally 'it doesn't bother me even a little.' Emphasizes that something doesn't affect you emotionally.
