Cookie Policy

Last updated: 24 June 2026

We keep cookies and similar storage to a minimum. You can reject non-essential cookies as easily as accepting them, using the banner shown on your first visit, and you can change your choice at any time (see “Changing your mind” below). No non-essential script runs before you consent.

Strictly necessary

These are always on because the site needs them. They store no marketing data.

  • theme (local storage) — remembers your light/dark choice. Persistent.
  • nobox-consent (local storage) — remembers your cookie choice for 6 months.
  • nobox-cart-v1 (local storage) — remembers items in your shopping cart on this device.

Analytics — optional, only after you accept

If you accept, we use Google Analytics 4 (provider: Google) to understand, in aggregate, which pages are helpful. IP addresses are anonymised and Google Consent Mode keeps analytics off until you opt in.

  • _ga — distinguishes users. Duration: up to 2 years.
  • _ga_<id> — keeps session state. Duration: up to 2 years.

Analytics data is retained by Google for up to 14 months. Google may process data outside the EEA under the EU–US Data Privacy Framework; see our Privacy Policy.

Advertising — optional, only after you accept

If you accept, we use the Meta Pixel (provider: Meta Platforms Ireland Ltd) to measure whether our ads on Facebook and Instagram bring readers here and, where applicable, to show our ads to people who have already visited the site. It loads only after you opt in — never before.

  • _fbp — identifies the browser for ad measurement. Duration: up to 3 months.

Data is shared with Meta and may be processed outside the EEA (including the United States) under the EU–US Data Privacy Framework and/or Standard Contractual Clauses. You can withdraw consent any time via “Changing your mind” below, and control ad personalisation in your Facebook/Instagram settings.

Fonts & media

Fonts are served from this website (not a third party), so viewing the site doesn’t share your data with an external font provider.

Changing your mind

You can withdraw or change your consent at any time, without clearing your browser:

This re-opens the banner so you can accept or reject non-essential cookies again. You can also use the “Cookie settings” link in the footer of every page.
