A site for showing / hiding on multiple tracker sites with a single button click.
Imaging you go to lunch for example, and don't want to be disturbed, then you can hide yourself on all sites with a single button click.
How to use:
Go to the settings-view, add the URIs of the sites you want to control (Ex taxi.closeby.market)
From the main-view: Press the key-button for respective site.
This will generate a key and create an url (looking like https://taxi.closeby.market/?keyFromExternalTracker=XXXXXXXXXXXXX) and redirect you to that url.
Presumably the site will know what to do with the "keyFromExternalTracker" in the query string and allow you to login and store the key.
Then you can use on/off to show/hide yourself on all the sites on the list.
