## Make links big again!

This is the opposite of bit.ly: instead of shortening URLs and hiding a bunch
of tracking data in them, this tool follows redirects to get the full-length
link, and *tries* to remove tracking parameters and cache results to shield
further requests to the same URL from being trackable. Redirects are followed
by our server, not your browser, so redirects collect our server's metadata
rather than your browser's metadata. This isn't a comprehensive protection
against all tracking, but I hope it can become one tool in a larger
anti-tracking suite.

No API is provided at this time, but ultimately this will be most useful if
it has an API which allows it to be used in browser extensions.
