Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity for website operators and providing other services relating to website activity and internet usage. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf.

Google Analytics full terms of service are available here:
Session cookie ("sid")
We also use a session cookie called "sid" (Session ID) which is required to allow users to log in (e.g. to the Parents' Directory).
It is not used to track your actions on the website, and it doesn't contain any personal or sensitive information.
This cookie is deleted automatically when you close your web browser. The related session data (e.g. your user ID) is deleted from the server after approximately 6-8 hours.
From time to time we may display a popup questionnaire to collect visitor opinions. We use three cookies to track your response to our website questionnaire:
- questionnaireN_start (records when you first visited the website)
- questionnaireN_later (records the time you clicked the "Maybe Later" button)
- questionnaireN_response (records if you have responded to the questionnaire)
(Where 'N' is a number.)
These are only used to determine whether and when to show you the questionnaire popup, and are not used for tracking or associated with any data we hold.
The "start" cookie is deleted when you close your web browser. The other two cookies are saved for up to 2 years, to avoid prompting you again on repeat visits.
Opting out of cookies
If you click the "Opt out" button below we will delete the Google Analytics cookies and disable Google Analytics on all subsequent pages. To do this we will set another cookie called "CookieManager" that remembers your decision to opt out. You can change this setting at any time by returning to this page.
Alternatively you can install the Google Analytics Opt-out Browser Add-on to block Google Analytics on all websites, or configure your browser to block cookies.
