The controller is established in France. The EU General Data Protection Regulation (GDPR) and the French Data Protection Act apply to the processing described below, whatever the country you visit this website from.

The website collects data in the following cases:

• Cookie-free visit measurement (Cloudflare Web Analytics): number of visits and page views, page viewed, referring page, country, browser type and page load times, combined into anonymous statistics. No cookie or identifier is placed on your device, and your browsing is not tracked from one website to another: this measurement therefore does not require your consent.

• Audience measurement (Google Analytics through Google Tag Manager): pseudonymised browsing data (pages viewed, session duration, device type, traffic source). Activated only after your explicit consent through the cookie banner.

• Behavioural analysis (Microsoft Clarity through Google Tag Manager): pseudonymised session recordings and heatmaps to understand how the website is used (movements, clicks, scrolling). Activated only after your explicit consent through the cookie banner.

• Technical error monitoring (Sentry): when a technical error occurs on the website, a report containing the error message, the page concerned and the browser type is sent to Sentry so that we can fix the problem. Your IP address is never sent, and no video or recording of your browsing is made.

• Push notifications: if you agree to receive notifications, a technical subscription identifier is kept by our hosting provider, with no name or email address attached.

• Booking a call (cal.eu): when you book, your name, email address and any message are processed by the cal.eu booking tool, published by Cal.com, under its own privacy policy.

• Contact by email: the data you send us voluntarily by email (name, email address, message content) is processed to answer your request.

• Article comments: if you post a comment, your name and message are kept; your email address is optional and never shown publicly. A non-reversible technical fingerprint of your IP address is computed to limit abuse, together with an anti-bot check. Every comment is reviewed manually before publication.

• Likes on articles: no personal data is collected; only a non-reversible technical fingerprint of your IP address is kept so that the same visitor is not counted more than once.

• Map (Google Maps): pages showing a service area in France offer a map provided by Google Maps. It loads only after you accept cookies in the banner, or if you click the button that shows the map. Google then receives your IP address and sets its own cookies in your browser. Until the map is shown, no request is sent to Google.

• Business relationship management: when you contact us or become a client, your contact details and the history of our exchanges are kept in a customer relationship management tool that we host ourselves, on a server located in France. It holds your business contact details, the follow-up of our exchanges, your quotes and invoices, and the emails we exchange, automatically linked to your record. This data does not come from your browsing on this website: it is the data you give us in the course of our business relationship.

• Consent: audience measurement (Google Analytics and Microsoft Clarity cookies), map display (Google Maps), push notifications, posting a comment.

• Legitimate interest: website security, anonymous visit measurement (Cloudflare Web Analytics), technical error monitoring (Sentry), prevention of abuse on comments and likes (IP fingerprint, anti-bot check), and follow-up of the business relationship with our prospects and clients in our management tool.

• Performance of a contract or pre-contractual steps: booking a call, answering contact requests.

This website uses the following cookies:

• Strictly necessary cookies: storing your cookie consent choice. No consent required.

• Analytics cookies (Google Analytics, Microsoft Clarity): set only after your consent through the cookie banner. You can withdraw your consent at any time by deleting your cookies or using the banner.

• Google Maps cookies: set by Google only when a map is shown, that is after you accept cookies in the banner or click the map button. You can delete them at any time in your browser settings.

Technical error monitoring (Sentry) and visit measurement (Cloudflare Web Analytics) set no cookie and work independently of cookie consent. Apart from the cookies listed above, no other tracker is placed on your browser.

• Analytics data: 14 months (Google Analytics setting).

• Visit statistics (Cloudflare Web Analytics): kept by Cloudflare in aggregated, anonymous form, with no data that could identify a visitor.

• Behavioural analysis (Microsoft Clarity): session recordings kept for 30 days by Microsoft, except a random sample and recordings marked as favourites, kept for up to 9 months; heatmaps available for up to 9 months.

• Technical error reports (Sentry): 30 days, then deleted automatically.

• Push subscriptions: until you unsubscribe or the subscription technically expires.

• Booking data: kept by cal.eu (Cal.com, Inc.) under its own policy, and by OLHYN for the duration of the business relationship, then 3 years for prospecting purposes.

• Contact emails: for as long as needed to handle the request, then 3 years at most.

• Comments: published comments are kept as editorial content of the website; rejected or unmoderated comments may be deleted during moderation.

• Likes: the technical IP fingerprint is kept while the like remains active, with no separate time limit from the content concerned.

• Business management data: for the duration of the business relationship, then 3 years from the last contact for a prospect. Accounting records follow their own statutory retention periods.

• Emails linked to your record: kept under the same conditions as the record they relate to.

Some data may be transferred outside the EU through the following providers:

• Cloudflare, Inc. (United States): website hosting, anonymous visit measurement, storage of push subscriptions and comments in databases created in Europe, and anti-bot checks. Cloudflare participates in the EU-US Data Privacy Framework.

• Google LLC (United States): audience measurement through Google Analytics and maps through Google Maps. Google participates in the EU-US Data Privacy Framework.

• Microsoft Corporation (United States): behavioural analysis through Microsoft Clarity. Microsoft participates in the EU-US Data Privacy Framework.

• Cal.com, Inc. (United States), publisher of the cal.eu booking tool: management of call bookings.

• Stripe Payments Europe, Limited (Ireland): online payment of a paid consultation booked through cal.eu, under Stripe's privacy policy. Stripe may transfer this data to Stripe, Inc. (United States), which participates in the EU-US Data Privacy Framework.

• Dropbox, Inc. (United States): archiving of the accounting records (quotes, invoices, receipts) of our clients and suppliers. Dropbox participates in the EU-US Data Privacy Framework.

• Infomaniak Network SA (Switzerland): hosting of our mailbox; the emails you send us are received and stored there. Switzerland benefits from an adequacy decision of the European Commission.

• SMTP2GO Ltd (New Zealand): delivery of the emails we send you from our customer relationship management tool (follow-up of your requests). The service does not keep the content of emails, apart from occasional anti-abuse checks. New Zealand benefits from an adequacy decision of the European Commission.

Our internal management tools are hosted by Oracle Corporation on a server located in Paris: the business data they contain does not leave the European Union.

These transfers are covered by appropriate safeguards (Data Privacy Framework, standard contractual clauses) in accordance with the GDPR. Technical error reports (Sentry) are not transferred outside the European Union: the account used is hosted in the European region (Frankfurt).

Under the GDPR and the French Data Protection Act, you have the following rights:

• Right of access: obtain confirmation that data about you is processed and receive a copy.

• Right to rectification: have inaccurate or incomplete data corrected.

• Right to erasure: request deletion of your data under the conditions set by law.

• Right to object: object to the processing of your data on legitimate grounds.

• Right to data portability: receive your data in a structured, machine-readable format.

• Right to withdraw consent: withdraw your consent at any time (cookies, push notifications).

To exercise your rights, use the contact page.

You may lodge a complaint with the French supervisory authority, the CNIL (Commission Nationale de l'Informatique et des Libertés), or with the supervisory authority of the EU country where you live, work or where the alleged infringement took place. If you live outside the European Union, you may also contact your local data protection authority.

This privacy policy may be changed at any time. The date of the last update is shown at the top of this page.
