Tracking is rife on the Internet, all 100% of websites in the Top 100 carry out tracking. In fact three sites in the Top 100 are trackers / advertising [1], that given the choice you wouldn't willingly visit:

CookiePedia shows that on average 17 cookies are dropped to your computer each site you visit, with only the minority (9%) actually being useful for functionality and use of the website. [2]


1: June 2016 Alexa had onclickads.net, outbrain.com, popads.net in top 100

2: Stats taken from CookiePedia on 28 July 2016

Why should I care? I have nothing to hide.

How would you feel if one day you searched for chest pain. Then after being bombarded with adverts for fake medicines, you find your medical insurance is invalidated because you're at risk of having a heart attack and failed to disclose the information to your insurer.[3]

Does it sound too far fetched that tracking companies would sell details to insurance companies? Well the technology already exists for this level of privacy invasion.

Fighting back against Tracking

NoTrack is a network-wide tracker blocker. You can install it on a small lightweight Linux computer, e.g. a Raspberry Pi. It sink-holes requests for known tracking domains, and prevents all your systems from being tracked.
Currently the list sits at over 14,000 known tracking domains.

Features
DNS Query Log

DNS Query Log contains a record of all the DNS requests made by systems on your network. You can find out how many sites were blocked for a particular reason, or you can look back through a line-by-line detailed log listing the activity of a particular system.

The DNS Query Log has convenient shortcuts to block/allow a particular site. You can also submit sites you believe to be tracking, so the wider community of users can benefit.

Top Level Domain Blocking

Some domains are cheap/free, and as a result attract a high number of malicious websites. The lifetime of some sites can be as low as a few hours, so its almost impossible to block them through a traditional blocklist. NoTrack provides you the option to completely block access to the worst of these top level domains.
Think of it trying to avoid a bad neighbourhood.

NoTrack Analytics

NoTrack analytics will monitor your traffic and provide an Alert when any of your devices attempt to access known malware sites, as well as for sites suspected of being related to tracking, but have not yet been blocked.
You have the option of Investigating the traffic further, Whitelisting, or Blacklisting the site. Once completed you can Resolve or Delete the alert.

Analytics runs on your system locally. None of your data is ever transmitted. This feature will be expanded further in future versions of NoTrack.

How To Install NoTrack

The preferred method of running NoTrack is on a lightweight ARM device, such as a Raspberry Pi. NoTrack works better under a Debian or Ubuntu Linux distro. Use Raspbian Lite if plan to run NoTrack on a Raspberry Pi.

Use the NoTrack install script:

wget https://gitlab.com/quidsup/notrack/raw/master/install.sh
bash install.sh
