> The information collected includes categorized web browsing history that shows how long and how often you visited specific categories of sites (i.e. social media, personal finance, or news). All site visits are classified into one of 30 categories. We do not collect URLs, web pages titles, or user-specific content without explicit permission from you.

From a technical perspective, how does this work? I can only think of two ways:

(1) Intel downloads a big "map" file containing a huge list of pre-defined domains and categories. This means either the categories are pretty slim or you have a GB's big file

(2) Each URL is sent to Intel (aka "collected"). Maybe they don't "store" it ("We promise") but as soon as it leaves your system you have no control on this

They could use a technique like Google Safe Browsing where you send a partial hash of the url, and they send back the subset of the map containing only urls which could match that hash
