Welcome to c0menius (referred to as "COMENIUS", "we", "us", or "our"), a spatial interface for human knowledge operated by SOGLAB LIMITED ("SOGLAB"), a company registered in England and Wales (Company Registration Number: 12816260; Registered Office Address: 338a Regents Park Road, Finchley Central, London, England, N3 2LN).

This Cookie and Local Storage Policy explains how we use cookies, browser Local Storage, and similar tracking technologies when you interact with our website (https://c0menius.app), use our no-code STUDIO creator platform, or access our WebXR digital curation experiences (the "Marketplace") at participating cultural institutions.

Because COMENIUS is built on a "no-app download" philosophy, our augmented reality (AR) and audio-guided experiences run directly within your mobile device's web browser (e.g., Safari, Chrome) via WebXR technology [396]. This policy details how we utilize browser-based storage to deliver a frictionless, reliable, and privacy-first experience [374, 381].

1. What Are Cookies and Browser Local Storage?

• Cookies: Small text files stored on your device (computer or mobile) by a website you visit. They are commonly used to make websites work, improve efficiency, or provide telemetry.

• Browser Local Storage (Local Storage & Session Storage): A modern web technology that allows a website to store data directly inside your web browser’s local cache [381]. Unlike cookies, Local Storage can hold slightly larger amounts of data and does not expire automatically unless cleared, while Session Storage is cleared the moment you close your browser tab.

COMENIUS relies heavily on Local Storage and Session Storage rather than traditional tracking cookies to ensure that your AR journey is not interrupted by cellular dead zones typical of historical buildings [381].

2. How We Use These Technologies

We use cookies and local browser storage for three primary purposes [381]:

A. Strictly Necessary Technologies (Frictionless Experience & Device Calibration)

These browser caching mechanisms are essential for our services to function. They cannot be disabled as they provide the core technical foundation of our WebXR delivery:

• WebXR Device Calibration: Caching basic screen size, camera orientation parameters, and device model info in the browser's Session Storage [379]. This ensures that the WebXR engine (powered by WebXR-compatible frameworks) scales 3D voxel models and places AR elements precisely in real-world alignment [377, 379].

• Authentication & Security: For curatorial staff using our STUDIO platform, session identifiers are used to keep you securely logged into your account workspace and Assets Manager ("Knowledge Vault") during editing sessions [378, 383].

B. Performance, Progress Caching, and Continuity (Sovereign Learning Progress)

To combat "digital exhaustion" and ensure accessibility, COMENIUS is designed to be highly resilient to variable network environments on-site [396, 403]:

• Progress Caching: We use browser Local Storage to temporarily save your active position on a "Curated Learning Journey" [381]. If your cellular signal drops or you accidentally refresh your mobile browser in a thick-walled stone gallery, Local Storage remembers which stops you have completed, your current audio-guide playback position, and earned milestones [381]. This prevents you from having to restart the experience from the beginning.

• User Preferences: Storing your language settings so that the AI-powered audio guide is rendered in your preferred language without asking you at every single artifact.

C. Anonymous Visitor Telemetry (ROI Reporting)

We use anonymous telemetry to understand how visitors interact with museum exhibits. This data is fully aggregated and does not contain Personally Identifiable Information (PII) [376, 381]:

• Engagement Metrics: Tracking which AR hotspots are clicked, the average minutes spent interacting with a digital layer (dwell-time), and route completion rates [379, 397].

• System Optimization: Monitoring loading speeds and browser rendering performance across different mobile devices to identify compatibility bottlenecks [379].

3. Third-Party Technologies in Our Ecosystem

COMENIUS works with selected, GDPR-compliant service providers to deliver advanced features. These providers may set browser cache parameters during your session [382]:

• WebXR Tracking Libraries: Browser-compatible frameworks process camera video feeds strictly on-device in the local browser cache for SLAM spatial mapping [377]. These scripts store temporary parameters in Session Storage to manage spatial positioning, which are cleared immediately when the browser tab is closed [377].

• AI Synthesis (STUDIO Users): For curators creating AI-powered audio guides, text prompts are processed securely via the Google Cloud Text-to-Audio API [382]. This transactional synthesis does not drop cookies or track visiting museum-goers [382].

4. Zero Cross-Site Tracking Promise

SOGLAB values your digital privacy. COMENIUS does not use, and will never use, cross-site tracking cookies, behavioral targeting cookies, or advertising networks [381].

We do not follow you across the internet, build behavioral profiles for advertising, or share your browsing history with third-party brokers [381]. All browser storage used during your museum visit is strictly localized to the COMENIUS domain (c0menius.app) and the specific, curated learning route you chose to explore [381].

5. Managing Your Cookie and Local Storage Preferences

You have the right to control how your browser handles local caching and cookies.

• Browser Settings: You can configure your mobile or desktop browser (Safari, Chrome, Firefox, Edge) to reject all cookies, block Local Storage, or notify you when a site attempts to write data to your cache. Please consult your browser's "Help" or "Privacy" settings menu for instructions.

• Effect of Blocking: If you choose to block Local Storage or strictly necessary cookies, the COMENIUS website and STUDIO editor will not function correctly. For museum visitors, blocking local storage will disable the progress-continuity feature, meaning any signal loss or browser refresh will cause you to lose your current spot on the curated route.

• Clearing Caches: You can clear all cached progress, cookies, and local data at any time by clearing your mobile browser’s history and website data.

6. Updates to This Policy

We may update this Cookie and Local Storage Policy from time to time to reflect changes in our technology, browser standards, or legal requirements. Any updates will be posted on this page with an updated "Last Updated" date. We encourage you to review this policy periodically to stay informed about how we safeguard your digital footprint.
