>Is this information enough for them to uniquely identify and track each user? No. How could they identify who i am based on that information alone?

1) each installation profile is assigned a unique user ID that is stored on your computer 2) every 24 hours it sends IP, ID, version, cpu architecture, screen resolution and time since last message 3) then we store the resolved approximate location after using a local geoip lookup So, what they have for each ID: approximate location, CPU architecture, screen resolution. They can easily know places you visited. From Quant's privacy policy: "French law makes it mandatory to keep some connection data (e.g. user ID used, URL or position, nature of the operation, time…) for one year."

  Add to that that we don’t know how the ID is generated and it can be system derrived.

  But how how they identify me?

    Statistically, if they geolocate you once per 24h, they will find you either at home or at work. Once both locations are known, determining which is which does not strike me as very hard.

      Yeap. When I got my first android phone Google needed one roundtrip to determine where I live and work.

      But their only method of location is IP, with the last octet removed. No way that's accurate enough to identify your home and work location.

        If you are working in any bigger company they have more than a C class, so they can identify company. If you go there frequently you are employee. You can infer how often /24 changes, means you are traveling or even commuting between work and home. You can't infer exact location but some close area can be guessed. They have a set of data for bigger group so they can create highly probable guesses what people may be doing and where they are.

  To be exact, it is 'the IP address of Vivaldi users by removing the last octet of the IP address'. It's true that they can still approximate location based on that. But unless you're travelling a lot so that you've many locations in their record, it's impossible for them to identify you.

Identifying a user does not have to mean that they can know your home address and name. Identification can mean that one is able to determine whether a user is the same across two separate instances of usage/visit.
