What data may be processed
If you accept analytics, technical and browsing data may be processed, such as your IP address, date and time of visit, pages viewed, referring URL, browser, operating system, language, screen size or resolution, and similar device data.
This data is used to understand how the website is used and to improve it. This site does not use that information to sell personal data or make automated decisions about visitors.
Analytics, cookies and lawful basis
We use Statcounter as an external analytics service to understand how the site is used and to improve its content, design and behaviour.

Statcounter may use the is_unique analytics cookie to distinguish new and
returning visitors. In addition, Statcounter-specific client storage has been disabled on this
site to reduce the use of extra cookies.
Your analytics preference is stored locally in this browser for 6 months so your choice can be remembered.
Recipients and retention
Analytics data is processed through Statcounter as an external technology provider. How long that information is kept depends on the service configuration and the provider's own privacy policy.
If new services, forms or integrations are added to this website in the future, this policy will be updated to reflect those changes.
