Cookie & Local Storage Policy

§1 · Storage Principles

1. Cookie & Browser Storage Overview

In accordance with the Privacy and Electronic Communications Regulations (PECR) and UK GDPR, Mudlark Spins distinguishes strictly between essential technical tokens required to operate the conservatory and optional telemetry controlled by you.

§2 · Essential HTTP Cookies

2. Strictly Necessary Cookies

The following first-party cookies are essential to maintain authentication state and consistent typography rendering across page transitions:

Cookie Name	Provider	Purpose	Duration
`PHPSESSID` / `scn`	mudlarkspins.com (First-Party)	Essential first-party session continuity token used to maintain request state and collector authentication.	Session / 30 Days
`ab_font_variant`	mudlarkspins.com (First-Party)	Essential interface rendering and typography profile token (`HttpOnly`).	30 Days

§3 · Client-Side Persistence

3. Local Storage & Session Storage Tokens

To keep your personal Wax Tallies and lighting scene active without unnecessary server round-trips, your browser stores the following keys locally on your device:

Storage Key	Storage Type	Technical Function
`mdk:claims`	`localStorage`	Stores the JSON array of foreshore relic slugs you have marked with a personal Wax Tally.
`mdk:recent`	`localStorage`	Stores up to 6 recently inspected relic slugs to populate your personal Collector Tray.
`mdk:scene`	`localStorage`	Remembers your chosen conservatory lighting scene (`chalk-dawn`, `amber-lantern`, or `obsidian-estuary`).
`mdk:analytics-consent`	`localStorage`	Records your explicit Google Consent Mode v2 decision (`granted` or `denied`).

§4 · Default-Denied Telemetry

4. Google Consent Mode v2 Architecture

On every page load, prior to any optional script execution, our document head initialises Google Consent Mode v2 with all advertising and analytics storage parameters strictly set to denied:

window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('consent', 'default', {
  'ad_user_data': 'denied',
  'analytics_storage': 'denied',
  'ad_storage': 'denied',
  'ad_personalization': 'denied',
  'wait_for_update': 640
});

§5 · User Command

5. Browser Controls & Preference Panel

You can inspect or toggle your Consent Mode v2 state at any moment on our interactive Consent Mode v2 Controls page, or clear site data directly through your browser’s privacy settings.
