2. What data we process

This website does not set analytics cookies. The interactive property demos use Vercel Web Analytics for aggregate traffic statistics, as described below. We process personal data in the following cases:

• Interactive demo traffic statistics. The pages /3d-app-demo, /3d-app-demo-2, /belle-epoque-demo and /casa-avenida-demo use Vercel Web Analytics to measure page views and estimated unique visitors, referral sources, approximate geographic location, and browser and device types. Vercel uses a request-derived visitor hash with a lifespan of up to 24 hours rather than analytics cookies. Our integration removes query strings and room identifiers from the page URL and does not send conversation text, contact details or custom interaction events to analytics. Local tests and preview deployments are excluded. The analytics script is not loaded when the browser signals Global Privacy Control or Do Not Track. Details: Vercel Web Analytics privacy information.
• Contact and bookings. When you contact us by email or book a call, we process the information you provide (name, email address, and the content of your message) to respond to your enquiry (Art. 6(1)(b) and (f) GDPR).
• AI concierge pages. We build and operate AI concierge chat pages for client businesses and as demonstrations. When you use one, the text you type is processed to generate a reply and is transmitted for that purpose to Anthropic PBC (USA) as the AI model provider. Conversations are logged so that the business the concierge represents can see what visitors asked, and short-lived technical counters are kept for abuse prevention. If you choose to leave contact details (such as an email address, dates, or a request), they are stored and forwarded to that business, which is the data controller for its own leads; email notifications are delivered via Resend, Inc. (USA). Concierge pages are hosted on Cloudflare Workers (Cloudflare, Inc., USA). Please do not enter sensitive personal data into a concierge chat.
• Thompson House 3D experiences. Questions, recent conversation and selected or saved room identifiers are processed through each demo’s dedicated Cloudflare Worker and sent to Anthropic to generate answers. These demos do not store transcripts or collect leads. Saved room choices stay in this tab’s session. Expiring technical counters limit abuse.
• Casa Avenida development experience. Questions and recent conversation at /casa-avenida-demo are processed by its dedicated Cloudflare Worker and Cloudflare Workers AI. This demo does not store transcripts or collect leads; chat stays in page memory. Expiring hashed visitor counters limit abuse. Links to the property’s sales team open its official website.
• Previous concept experience (retired). This earlier demonstration used its own Cloudflare Worker. Free-form questions, recent conversation and the selected room were sent to Anthropic to generate a reply. No conversation transcripts or leads were stored; chat stayed in page memory. Daily hashed visitor counters expired within 25 hours.
• Villa Belvédère concept residence. The concierge at /belle-epoque-demo uses its own Cloudflare Worker and Cloudflare Workers AI. Free-form questions, recent conversation and the selected room or level are processed to generate answers. Reviewed suggested questions can be answered directly. This demo does not store transcripts or collect leads; chat stays in page memory. Expiring hashed visitor counters in a dedicated namespace limit abuse and expire within 25 hours. The link to discuss your property opens Quant49’s separate booking page.

Where data is processed in the United States, transfers are safeguarded by the EU Standard Contractual Clauses.
