Cookie Policy & Storage Architecture

Publication Date: January 2026 • Technical Review: March 2026

1. Principles of Technical Data Storage

This Cookie Policy explains how Reelradarpurepixls Unipessoal Lda. utilizes cookies, browser local storage tokens, and related web technologies on reelradarpurepixls.sbs. In adherence to the ePrivacy Directive (Directive 2002/58/EC as amended) and Portuguese Law No. 41/2004, we maintain an intentionally minimal storage profile, rejecting intrusive behavioral tracking mechanisms and third-party advertising cookies.

2. Technical Cookie Inventory

The table below provides a full itemization of technical identifiers, purposes, categories, and retention lifecycles utilized across our static publishing domain:

Identifier / Key Classification Technical Purpose Duration Storage Channel
rr_cookie_consent Strictly Necessary Stores user preference (accept / reject / preferences) to prevent re-displaying the bottom banner across sessions. 365 Days HTML5 localStorage
rr_nav_pref Functional Remembers viewport layout state and mobile navigation drawer dismissal preferences during single-session journeys. Session only HTML5 sessionStorage
rr_anon_metrics Analytical (Anonymized) Aggregates coarse page load performance and SVG rendering times without storing personal IP or fingerprint vectors. 90 Days First-party cookie

3. Cookie Categories and Functional Scope

  • Strictly Necessary Cookies: These tokens are required for core site functionality, including cybersecurity defense, load balancing, and remembering your consent state. Without these files, basic navigational operations would fail. Under applicable EU directives, strictly necessary cookies do not require prior opt-in consent.
  • Functional Storage: Used to maintain client-side accessibility selections, such as high-contrast preferences and font-scale sizing across page transitions.
  • Analytical Measurement: Used solely to generate aggregated, non-personally identifiable metrics on page latency, missing asset detection, and responsive viewport errors across diverse hardware.

4. Browser-Level Cookie Management & Opt-Out

In addition to using the interactive cookie banner buttons provided on our site, you can manage, inspect, or delete cookies at any time through your web browser preferences:

  • Mozilla Firefox: Navigate to Settings → Privacy & Security → Cookies and Site Data. Select "Clear Data" or configure custom blocking rules.
  • Google Chrome: Open Settings → Privacy and security → Third-party cookies. Adjust global permissions or purge local site data.
  • Apple Safari: Choose Preferences → Privacy, then select "Prevent cross-site tracking" and "Block all cookies" as desired.
  • Microsoft Edge: Go to Settings → Cookies and site permissions → Manage and delete cookies and site data.

Please note that disabling strictly necessary local storage may prevent the cookie banner from remembering your dismissal preferences, causing it to appear on subsequent page loads.

5. Policy Updates and Regulatory Inquiries

We periodically review our storage architecture to ensure ongoing compliance with European Union directives and guidelines published by the European Data Protection Board (EDPB). Any revisions will be recorded on this page with an updated revision date.

For technical inquiries regarding cookie deployment on this site, contact our systems administration team at [email protected].
