Google’s Chrome web browser on Android now finally supports approximate location sharing. So now you can set it so that it only gets an approximate location from your device to send to whatever website wants it. Previously, Chrome always wanted access to your precise location, which is overkill for most websites.
You can still use your precise location when you need to, by the way, that’s not going away. Google is planning to release a new API for web developers that lets them request your approximate location directly, or specify if they need your precise location.
