F-Secure FREEDOME Anti-Tracking feature explained
What does it block?
The feature does all of the following:
- Removes all cookies set by known advertising networks, preventing the ad networks from tracking individual visitors from site to site.
- Prevents all HTTP traffic from and to what is considered a "tracking domain", preventing also existing cookies to be sent back to those domains.
- Forces the Do Not Track header on for all browsing.
When the site you visit uses third-party analytics services known to our database or advertisements from ad networks over HTTP, FREEDOME either blocks these requests completely, or strips cookies from them. Those third parties are unable to track which sites you're visiting.
We do not block anything going from your browser to the site you're visiting. Blocking cookies from the site you visit easily breaks login sessions, stored preferences and other valuable features. We do highly value privacy and are committed to maintaining this feature while not sacrificing usability in the Internet.
F-Secure's Security Labs are running a real-time reputation service that the FREEDOME service uses. This reputation system has information about what is considered tracking by F-Secure Labs/analysts. The detailed list of blocked domains, URLs, etc. are considered F-Secure trade secret and the whole list cannot be provided as such.
What doesn't it block?
FREEDOME does not block any tracking from HTTPS traffic because that would require a man-in-the-middle attack against the HTTPS, and we've decided that the security risks related outweigh the possible privacy gains.
What do the statistics show?
The anti-tracking statistics in the F-Secure FREEDOME main user interface show currently only the total amount of web (HTTP) requests which were either blocked, or which had their cookies filtered to prevent tracking. Unfortunately, we are not able to provide more accurate data about what was blocked to our users since we do not log any traffic for privacy reasons.
FREEDOME never logs your data. However, you can use FREEDOME's Tracker Mapper to see how you are being tracked. Tracker Mapper allows you to temporarily log visited websites to see how they are tracking you. This log will be deleted permanently three days after you stop recording or as soon as you start a new log recording.
