Mathematically, the Fourier transform obeys an uncertainty principle. Here is a nice and simple writeup:

The discrete Fourier transform (which is what OP is talking about) doesn't satisfy an uncertainty principle as far as I know. The concept doesn't really make sense.

You can talk about these concepts without bringing information or precision into the picture.
