Privacy Policy, MAVI World

This Privacy Policy explains how MAVI World (operating the website at mavilongevity.com) collects, uses, and safeguards information you provide to us.

Who we are

MAVI World is a longevity-architecture studio headquartered in Geneva, Switzerland. References to we, us, and our in this policy refer to MAVI World.

The data controller for personal data collected through this website is MAVI World, contactable through our contact form.

What we collect

Address data. When you submit your address through the Snapshot field, the address is encrypted in transit and used only to compose your Snapshot. We do not store your address until you explicitly ask us to (typically by purchasing a Blueprint).

Contact data. When you write to us through the contact form or by email, we receive your name, email address, telephone (if provided), and the message you sent.

Your answers about your home. If you complete the Blueprint questions, we keep your answers: the type and age of the home, how you cook, ventilate and filter your water, what sits by your bed, who lives there, your health goals and what you hope the home will change for you.

Health information. One question asks about health conditions or sensitivities in your household, and another asks for your main health goal. Both are optional, and you can choose Prefer not to say. This is sensitive information. We use it only to score your Blueprint and to put the changes in the right order for you. We do not send your answer about health conditions to any AI model (see Artificial intelligence below).

Payment data. When you purchase a Blueprint, payment is processed by Stripe under its own privacy terms. We receive a confirmation, the last four digits of your card, and your billing country, never your full card details.

Site analytics. Cloudflare Web Analytics (privacy-first, cookieless) records aggregate page-views and country-level traffic. No individual user is identified.

Customer journey. If you complete the Snapshot or Blueprint flow, we record an anonymous session identifier and the steps you took, so we can improve the experience. No personally identifying data is attached to this record unless you have purchased.

How we use it

To deliver the Snapshot and Blueprint you have requested.
To have AI models draft the wording of your Snapshot and Blueprint (see below).
To respond to messages you send to us.
To process and fulfil payments.
To improve the website experience based on aggregate behaviour.
To send transactional emails (receipts, magic-link access, Blueprint delivery).

We do not sell your data, share it with advertisers, or use it for marketing without your explicit consent.

How long we keep it

Address data, before purchase: processed in memory; not persisted.
Address data, after purchase: retained for the lifetime of your Blueprint plus 12 months.
Contact-form submissions: retained for 24 months.
Payment records: retained as required by Swiss / EU tax law (10 years).
Customer-journey records: retained for 12 months, then aggregated.

Artificial intelligence

The wording of your Snapshot and your Blueprint is drafted by AI language models from Anthropic and OpenAI. They are given only what they need to write it:

the town, region, country and elevation of your home, and the public environmental readings we hold for it;
for a Blueprint, your answers about the home and your goals, including your main health goal and the age band of the main person living there.

They are never given your name, your email address, your street address, your answer about health conditions, your security answers, or your answers about who lives in the home and when it is empty. We ask OpenAI not to store these requests. Both providers process a request on their own servers, which can be outside Switzerland and the European Union, so we cannot say that this part of your data stays in Switzerland.

A Snapshot is written and delivered automatically, so nobody at MAVI reads it before it reaches you. A Blueprint is reviewed by Kas Bordier before it is delivered. The scores come from our own formula, not from the models.

Where it lives

All MAVI customer data is stored in a Zurich-region database (Swiss residency). Static assets and pages are served via Cloudflare’s global edge. Payment processing runs through Stripe (US-headquartered, with EU data-processing addenda in place). The AI providers named above and Klaviyo are the other places your data goes, as set out under Third-party processors.

Under the EU GDPR and the Swiss Federal Act on Data Protection, you have the right to:

Access the personal data we hold about you.
Rectify any inaccuracies.
Erase your data, subject to legal retention obligations.
Restrict processing.
Object to processing.
Portability, receive your data in a machine-readable format.
Withdraw consent at any time.

To exercise any of these rights, write to us through our contact form. We respond within thirty days.

Cookies and similar technologies

We use a minimal set of strictly-necessary cookies for site operation. Analytics cookies and customer-journey tracking are opt-in and controllable via the consent banner shown on first visit.

Third-party processors

The following processors handle data on our behalf, each under their own data-processing terms. Against each is what it receives.

Stripe (payments): the details you give at checkout, which Stripe holds under its own terms.
Resend (email): your email address and the emails we send you, such as receipts and your Snapshot.
Cloudflare (CDN, edge, analytics): page requests and aggregate, cookieless traffic figures.
Supabase (database, EU region): everything we store about you, including your address, your answers and your reports.
Anthropic and OpenAI (AI models): the home details and answers described under Artificial intelligence, and nothing that names you.
Klaviyo (email and customer journeys): your name and email address, whether you have agreed to receive marketing, how you came to us, the stage you have reached, the scores for your home, and purchase events with the amount paid. It does not receive your street address, your phone number or your answers.

We may update this policy from time to time. The updated date at the top of this page reflects the most recent revision. Material changes will be communicated to existing customers by email.
