>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?

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."
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.
