My opinion is;
you are free to translate whatever you want. No limitation at all. Especially if you only use it for your own self satisfaction. LOL
But the problem could come if other troublesome people start disturbing you because of it.
For example, if you post it somewhere they could read it.
So, my suggestion is, just translate it, and post it somewhere private where only the people you could trust that has access on it.
Or, you could translate it and then post it everywhere anonymously. 🤣
