The contraction requires an apostrophe because don’t is short for do not.
Using “do not” when the tone is too formal
In casual conversation:
I do not know what you’re talking about.
This is grammatically correct but can sound unusually formal.
More natural:
I don’t know what you’re talking about.
Confusing “don’t” with “doesn’t”
Use don’t with I, you, we, and they.
I don’t know.
They don’t agree.

This can strongly emphasize the speaker’s refusal.
Compare:

This is neutral.
I do not want to go.
This can sound much more forceful.
