What is the Elertz Widget ?

The Elertz widget is a tiny piece of secure software which is used by a website or webportal to send an alert message to a user. The user can subscribe to whatever channel (like subscribing to a TV channel), by clicking on a link on a webpage and then receive information such as web pages and videos through that channel. You can unsubscribe to the channel simply by clicking "remove" and that is it, the website cannot contact you again unless you resubscribe.
