CLIENT TELEMETRY

Cookie & Telemetry Policy

Effective Date: November 12, 2026 • Compliant with UK PECR and UK GDPR Guidelines

1. Introduction & Regulatory Scope

This Cookie Policy explains how Britain Portcullis ("we", "us", or "our") uses cookies, local browser storage, and related web telemetry mechanisms on britainportcullis.com.

We operate under the Privacy and Electronic Communications Regulations 2003 (PECR) and the UK General Data Protection Regulation (UK GDPR). We believe in transparent telemetry and provide granular control over optional client storage.

2. What Are Cookies and Local Storage?

A cookie is a small text file transferred to your computer or mobile device upon visiting a website. Similar technologies include HTML5 LocalStorage, which enables web applications to store persistent user interface states directly within the client browser without repeatedly transmitting data to web servers.

3. Categories of Cookies & Client Identifiers Used

Identifier Type Lifespan Purpose & Operational Scope
bpc_consent_v2 LocalStorage (Functional) Persistent (12 Mo) Stores your decision regarding Google Consent Mode v2 (granted or denied).
_cfuvid / __cf_bm HTTP Cookie (Security) Session to 24 Hours Essential edge network protection, rate limiting, and bot mitigation.
_ga / _ga_* HTTP Cookie (Analytics) Up to 2 Years Consent-gated anonymized telemetry measuring WebGL compatibility and page latency.

4. Google Consent Mode v2 Architecture

britainportcullis.com implements Google Consent Mode v2 natively. By default, all analytical storage (analytics_storage) and advertising identifiers (ad_storage, ad_user_data, ad_personalization) are set to 'denied' before any script loads.

Analytical telemetry is only activated if you click "Accept All" in our interactive consent banner. Selecting "Decline Non-Essential" ensures that no analytical cookies are set.

5. How to Manage and Revoke Consent

You may change or revoke your cookie choices at any time by clearing your browser's local cache or clicking the preferences toggle in our footer. Additionally, all major web browsers provide settings allowing you to reject cookies:
