Browser storage

Cookie policy

This page lists the storage used by this site and explains how to change your optional privacy choices.

What cookies and local storage are

Cookies are small values a website asks a browser to store and return with later requests. Local storage saves a value in the browser without sending it with each page request. We use both only as described below.

Storage used by this site

NameType and categoryPurposeDuration
PHPSESSIDCookie · NecessaryMaintains the secure server session used for CSRF protection and form feedback.Session; normally removed when the browser session ends.
dl_consent_v1Local storage · NecessaryRecords the consent-policy version, timestamp and your analytics and marketing choices so the banner does not ask on every page.Until you clear site data or the consent version changes.

Consent categories

Necessary storage supports security, the enquiry form and remembering privacy choices. It cannot be disabled through the settings panel.

Analytics permission allows storage used to measure how the website is used. Marketing permission allows storage used to measure or personalise marketing. These two categories are off unless you allow them.

Manage your choices

On your first visit, you can accept all, reject all or open settings. The three first-layer buttons have the same prominence. In settings, analytics and marketing can be controlled independently.

You can also clear this site’s data in your browser. Doing so removes the saved choice and the banner will appear again.

How consent is applied

Optional storage is denied by default. When you save a choice, the site updates the relevant consent state to granted or denied and stores the choice with a version and timestamp. Rejecting optional categories does not stop the necessary session or consent record.
