No, you do not need hypoclear with film.

However, this is not quite the case with print washing, since paper, particularly fiber-based, can deteriorate with times sufficient to wash the hypo (fix) out of the emulsion and paper. HC is quite helpful in this regard.
FWIW, I treat roll film somewhat differently from sheet film. Roll film is hung in a "protected environment" after having been rinsed in photo-flo. I never squeegee roll film – the emulsion is soft at this point, and you're playing with fire. Sheet film only undergoes a final distilled water rinse (no photo-flo) and then hung to dry in the open in my lab. Both dry spot and streak free. Both share processing by mixing developers and final rinsing only in distilled water, even though I have filtered water available in my lab. You only get one chance with negatives, and distilled water seems a relatively small price to pay for some peace of mind, when processing film. You can try filtering water, but I think it will be a shot in the dark as to which reactive elements you are actually filtering that are important to your developing. I don't know why you cannot find distilled water in your neck of the woods, but it is pretty generally available, and you could always distill your own, if necessary.
