Where can I add custom hook so updates will not overwrite them?

I am looking for a child functions file, where I can add a custom hook, so it will not get overwritten with an update.

can someone tell me where that file that does not get overwritten with updates is?

hey @bizactuator better if you create a child theme then do your customisation on that child theme functions.php file.
