Privacy Policy

1. Data controller

The controller of personal data is the company that publishes and operates the website:

SENSASS FRANCE, a French limited liability company (SARL) trading under the commercial name "Booking Chauffeur by Precellence Service" (hereinafter "Precellence Service")
Registered office: 66 avenue des Champs-Élysées, 75008 Paris, France
SIRET: 814 627 618 00022 — RCS Paris 814 627 618
Email: [email protected]
Phone: +33 (0)1 58 96 39 43

The publisher's full details appear in the legal notice.

Precellence Service is committed to protecting the privacy of its clients in accordance with the EU General Data Protection Regulation (GDPR — Regulation EU 2016/679) and the French Data Protection Act of 6 January 1978 (loi Informatique et Libertés).

2. Data collected

As part of our private chauffeur services, we collect the following data:

• Identity: last name, first name
• Contact: email address, phone number
• Ride: pick-up address, destination, date and time
• Flight: flight number (for airport transfers only)
• Payment: payment data is processed directly by Stripe and is never stored on our servers
• Company: company name, job title (for B2B accounts only)
• Mobility aid (optional): if you tell us you travel with a cane, a walker or a wheelchair. This information may reveal health data: you provide it voluntarily, and it is used solely to prepare your ride (vehicle and assistance from the chauffeur).

AI assistants: public API and MCP server

AI assistants (for example Claude or ChatGPT) can request our prices and conditions through our read-only public API (/api/public/quote, /api/public/conditions) or our MCP server (https://precellence-service.com/mcp). These requests only describe the trip (pickup and drop-off places or addresses, date, time, number of passengers): no name, no contact details, no account. We keep no personal data from them: addresses are not written to our logs; the IP address is neither logged nor stored (the API rate limit keeps only a truncated fingerprint, deleted within 25 hours; the MCP server limit is shared by all its users and does not use the IP address); the answer to a request, which repeats the requested trip, is kept for 10 minutes in the cache of our host Cloudflare to serve the same request, then deleted. To compute the price, typed addresses are sent to Google (Maps Platform); places found are cached for at most 6 hours. No booking and no payment take place through the assistant: they happen on our website, where the other articles of this policy apply. The assistant you use processes your conversation under its own privacy policy.

3. Purpose of processing

Your personal data is used exclusively to:

• Process and confirm your private chauffeur bookings
• Communicate with you before, during and after the ride (messages by WhatsApp or email, flight tracking)
• Issue invoices and manage accounting
• Improve the quality of our services
• Reply to your contact or quote requests

We do not engage in any unsolicited commercial prospecting. You will never receive a newsletter without your explicit consent.

4. Legal basis

The processing of your data is based on (Article 6 GDPR):

• Performance of the contract (Art. 6(1)(b) GDPR): your data is necessary to perform the transport service you booked
• Legal obligation (Art. 6(1)(c) GDPR): retention of invoices in accordance with French tax law
• Consent (Art. 6(1)(a) GDPR): for any optional marketing communication (opt-in only)

5. Retention period

• Booking data: 3 years after the last booking
• Invoicing data: 10 years (legal accounting obligation under French law)
• Contact data: 3 years after the last contact
• Payment data: not retained (processed by Stripe)

Beyond these periods, your data is deleted or irreversibly anonymised.

6. Data sharing

Your data is never sold, rented or transmitted to third parties for commercial purposes.

The only recipients of your data are our technical service providers and our chauffeurs:

• Cloudflare, Inc. (website hosting) — for European users, data is processed within the European Union via Cloudflare Ireland Ltd. (Dublin); any transfers outside the EU are governed by the European Commission's Standard Contractual Clauses (Art. 46 GDPR)
• Stripe: secure credit card payment processing (PCI DSS certified)
• Resend / Amazon SES: sending of transactional emails (booking confirmation)
• IONOS: hosting of our email mailboxes (your email exchanges with us)
• WhatsApp (Meta group): your exchanges with us when you message us on WhatsApp
• Google (Firebase, Google Maps, Google Analytics 4, Google Fonts): booking database (Firebase), address autocomplete (Maps), statistical audience measurement (Analytics — see section 8), display of typefaces (Fonts: your IP address is sent to Google when pages load)
• Our chauffeurs and partner chauffeurs: only information necessary for the assignment (name, pick-up address, destination)

7. Your rights

In accordance with the GDPR (Articles 15 to 22), you have the following rights:

• Right of access: obtain a copy of your personal data
• Right of rectification: correct inaccurate or incomplete data
• Right of erasure ("right to be forgotten"): request the deletion of your data
• Right to portability: receive your data in a structured format
• Right to object: object to the processing of your data
• Right to restriction: restrict processing in certain cases

To exercise these rights, please contact us at: [email protected]

We undertake to respond within 30 days. You may also lodge a complaint with the CNIL (Commission Nationale de l'Informatique et des Libertés — the French Data Protection Authority) at cnil.fr/en.

8. Cookies

Our website uses:

• Technical cookies required for the website to function (navigation session, language preference)
• Audience-measurement cookies (Google Analytics 4), for statistical purposes only. They are set only with your consent, collected via our cookie banner; you may accept, refuse or withdraw this consent at any time, using the Manage cookies link at the bottom of every page. The Google Analytics script is only loaded after you agree.
• Microsoft Clarity (Microsoft Corporation), an audience-measurement tool that produces click maps and anonymised session recordings, used to improve the website's usability. It is loaded only after you agree (“Accept” button of the banner) and then sets the cookies _clck (1 year) and _clsk (1 day). Sensitive fields (name, phone, email, addresses, payment) are masked before any recording: their content is never sent. The data is processed by Microsoft, including outside the European Union, under the EU–US Data Privacy Framework. You may withdraw your consent at any time using the Manage cookies link: Clarity then deletes its cookies.
• Cookieless audience measurement (Cloudflare Web Analytics, Cloudflare Inc.): count of page views and loading times, with no cookie, no identifier and no cross-site tracking; no consent is therefore requested for this measurement.

We use no advertising or commercial-profiling cookies. No data is sold to advertising networks.

9. Security

We implement technical and organisational measures to protect your data:

• SSL/TLS encryption across the entire website
• Restricted access to personal data (principle of least privilege)
• Non-disclosure agreement (NDA) signed by the chauffeur at the client's request
• Secure hosting via Cloudflare (Cloudflare Ireland Ltd., Dublin, for European users' data)

10. Changes

This privacy policy may be updated at any time. The date of the most recent update is shown at the top of the page. We encourage you to review it regularly.
