Privacy policy

This page explains which data may be processed when you use this website and why.

Data controller

Antoine Quarroz, Rue de l’Evouette 5, 1969 Saint-Martin VS, Switzerland, is responsible for processing personal data through this website. Questions concerning your data may be sent to info@antoinequarroz.ch.

Full legal information

Data and purposes

Depending on how you use the website, the data processed may include your name, contact details, company, project message, appointment information, contractual and billing data, IP address, browser information, request timestamps and acquisition information such as the landing page, referrer and UTM parameters. This data is used to answer requests, qualify and follow up leads in the CRM, deliver projects, manage quotes and invoices, measure website use and secure the service.

Contact and appointments

Information you submit is used to answer your request, prepare a project discussion or organise an appointment. Email delivery uses Lumail, and appointments may open Cal.com.

Newsletter and practical resources

When you subscribe below a blog article or request a practical resource, your email address, language, source page, requested resource and consent date are recorded by this website and transferred to Lumail, the newsletter delivery platform. The requested resource is made available immediately. Lumail sends an address confirmation email, followed by one welcome email after confirmation. The subscription is voluntary and can be cancelled at any time by writing to info@antoinequarroz.ch or by using the unsubscribe link in each email. Newsletter data is not used to create an automatic sales sequence.

Service providers and recipients

Data is accessible only where needed by Antoine Quarroz and the providers used to operate the service: Infomaniak for hosting, Supabase for application data and authentication, Cloudflare Turnstile for abuse prevention, Lumail for email delivery, Cal.com for appointments, PostHog for audience measurement, Google for reviews and maps, and Stripe when online payments are used. Each provider processes data under its own contractual and privacy terms.

Audience measurement and attribution

PostHog measures public page views, outbound links, downloads and selected conversions in cookieless mode. PostHog stores no identifier in cookies or browser storage, creates no individual profile and records no session replay on this website. A privacy-preserving server hash is used to count visitors; the IP address is then stripped. The site also keeps landing-page, referrer and campaign parameters in the browser session so a request can be attributed to its source in the CRM.

Google Maps reviews

When Google reviews are enabled, the site requests live content from the Google Places API. Review author information, profile images and links are supplied by Google Maps. This content is not copied into the website database. Displaying remote Google content may establish a connection to Google.

Google privacy policy

Processing abroad

Infomaniak hosts in Switzerland. PostHog stores this project’s audience data in its European cloud. Supabase operates the configured project infrastructure in the European Union and may provide support from the United States. Lumail uses infrastructure in Germany, Australia, the United States and the Asia-Pacific region; Cal.com operates from the United States. Cloudflare, Google and Stripe use global infrastructure. International transfers require the safeguards applicable to each provider and destination.

Retention

Unsuccessful enquiries and CRM follow-up data are normally deleted or anonymised no later than three years after the last substantive contact. Project and contractual data is kept for the relationship and the time needed to establish or defend claims. Accounting records and supporting documents are retained for ten years from the end of the relevant financial year where Swiss law requires it. Technical logs are retained only for the period reasonably necessary for security and operation.

Your rights

Subject to applicable law, you may request access, correction, delivery or deletion of your personal data, or object to certain processing, by writing to info@antoinequarroz.ch. Identity may be verified before a request is fulfilled. Data required by law or to establish, exercise or defend legal claims may be retained. You may also contact the Swiss Federal Data Protection and Information Commissioner.
