LocalCDN is a bit of a "tin-foil hat" style privacy tool if you ask me.

The prospect of relatively generic online resources hosted on content delivery networks being used to track you is definitely questionable, but on the other hand, reducing your networking footprint is still a generally good thing to do regardless- and LocalCDN seems to help with that goal, to some extent.

It seems to work, and it rarely causes trouble for sites most of the time, and it even supports whitelisting individual sites, so when it does break things, you can make it unbreak those things.

It's good but it's still up in the air how much this is actually contributing to your online privacy, if you ask me.
