The co-browser provides intelligent information spaces for groups to share.

Each space filters and collates its active members' anonymised clickstream data in real time, using it to map out helpful connections between the webpages its members have been visiting. Users can turn it on or off, remove links, delete their history, and setup, join and leave spaces. Space adminstrators control which domains to exclude or include, who can use that space, and mergers with other spaces. Various aggregated metrics are supplied so you can figure out what works best for you.

Cookies are bits of information residing on your computer for a time, put there by the websites you visit and the webapps you use. They are used for all sorts things, like storing your preferences, as you move about on or revisit that website or webapp.

The co-browser uses Chrome sync storage associated with your Chrome browser instead of cookies, but it uses this in a similar way to cookies. If you are logged into Chrome, these stored variables are associated with your Google account and will follow you around onto other devices.

The co-browser stores a handful of ‘strictly necessary’ variables in your browser's sync storage - unique anonymised {!ctf} identifiers for you and the {!ctf} space you're using, whether you've consented to use the co-browser, an ID for the last URL you visited, the "page" you called for in the extension, whether the co-browser is ON or OFF etc. These are used to determine whether and how the background javascript sends data to the {!ctf} servers or requests data from the {!ctf} servers. The servers use the instructions they receive to process collated data from your space and form a response that is then presented in your co-browser.

Your input, by javascript and sync storage, is fundamental to the way the co-browser works and what it is for - sharing your filtered clickstream data in controlled groups for mutual benefit. As a result, the only direct option available to users regarding their browser's sync storage is whether the co-browser is switched ON or OFF. However, the co-browser supplies users and administrators with various other ways to customise how their spaces work.

The co-browser itself does not share any information with third parties, for example advertisers, but your traffic within websites, within Chrome or via other webapps may be monitored by them of course. When you log out of the co-browser, or delete content in the co-browser, the relevant {!ctf} sync storage is immediately deleted on that device.
