It depends on what you mean by "project management tools", I suppose.
My personal projects are generally done by a team of 1 (sometimes I'll bring in one or two friends, but not usually). Project management for a team that small is trivial.
What I use to manage my personal projects is just a wiki and a version control system. Project management tools add some friction and overhead, so they're only useful if they're reducing more friction and overhead somewhere else. Working alone already greatly reduces such overhead, rendering heavier-duty tools counterproductive for me.
