Location Guard Revived — DoomsDay

Websites can ask the browser for your location. Location Guard intercepts that
request and, if you allow the website to see your location at all, gives it a
fake one instead: either your real location with random noise added, so the
website only learns the general area you are in, or a fixed location that you
pick on a map.

Choose a privacy level per website. Low, medium and high control how much
noise is added, and the options page shows the protection area on a map so you
can see what each level means. "Use fixed location" always reports the same
place, wherever you are, and can skip the browser's location lookup entirely.

This is a maintained fork of the original Location Guard by Kostas
Chatzikokolakis, a product of research at École Polytechnique, CNRS and Inria
on geo-indistinguishability. The original has not been updated since 2022 and
its map and search stopped working. This fork keeps the same privacy design and
fixes:

• the map tiles, which OpenStreetMap had started blocking;
• the location search, which used a third-party service whose shared key had
  run out of quota, and now uses OpenStreetMap's own Nominatim;
• accurate attribution and privacy information.

Note: Location Guard protects against location requests made through the
browser. It does not hide your IP address, which websites can use to estimate
your location at city level.
