Last updated: 28 July 2026 · Version 1.0
This Cookie Policy explains how Thornton Nutrition Review Ltd ("we", "us", "our") uses cookies and similar tracking technologies on https://purifyppdrain.world/. It should be read alongside our Privacy Policy.
We comply with the Privacy and Electronic Communications Regulations 2003 (PECR), the UK GDPR, and the Data Protection Act 2018. Non-essential cookies are only set after you have given your explicit consent.
1. What Are Cookies?
Cookies are small text files placed on your device (computer, tablet, smartphone) when you visit a website. They allow the website to recognise your device and remember certain information about your visit - for example, your language preference or consent status.
Similar technologies include local storage (used by our consent module), session storage, and tracking pixels. This policy covers all of these.
2. How We Obtain Consent - Consent Mode v2
We implement Google Consent Mode v2 via the script js/consent-mode.js, which is loaded as the very first script in the page <head>. On page load, all non-essential consent signals default to denied:
ad_storage: deniedad_user_data: deniedad_personalization: deniedanalytics_storage: denied
These signals are updated to granted only when you click Accept All in our cookie consent banner, or when you save preferences with the relevant toggles switched on. Your choice is stored in localStorage under the key cookieConsent for 12 months. You may change your preference at any time by clearing your browser storage or contacting us.
