Hows this for an answer about data retention from BT

* How long do they keep the data? Seconds - or up to 14 days?


If you have BT Webwise activated, on each navigation, a 'data digest' is created consisting of URL, search terms submitted to a major search engine, and the top 10 most frequently-occurring page keywords from the page (which are cleaned to remove email addresses, numbers and names). This is matched against a list of advertising product categories. After the match is made, 'data digest' is deleted permanently and immediately. The 'data digest' is never written to disk so it is never stored. The matching information is only kept for 6 months and then deleted permanently.

So for 6 months they will have a record of what i did
