Privacy

Updated on October 14, 2026

You can browse this website without an account, without a form, without ads and without cookies. I only receive your personal data if you book a call or write to me.

Who is responsible for your data

Martin Drieu la Rochelle (PROPRIA), Paris, France.
For any question: martin@propriatech.io.

When you book a call

Bookings go through Cal.com. There, you provide:

This information is used for one thing only: preparing and holding our meeting, then getting back to you. It is processed because you asked for this exchange (pre-contractual measures, Article 6(1)(b) of the GDPR).

I do not sell it, I do not pass it on to anyone for advertising, and I do not add you to any mailing list.

When you write to me

By email, WhatsApp, Instagram or LinkedIn: I only use your message to reply to you. These services also apply their own privacy rules.

Who has access to your data

Only me. To operate, I rely on a few technical providers, who host or carry this data on my behalf:

Some of them are based outside the European Union, notably in the United States. These transfers are covered by the safeguards provided for by the GDPR.

How long I keep it

If we do not work together: no more than three years after our last exchange. If we do work together: for the duration of the project, then for the period required by law for invoices and accounting records (ten years).

Cookies and audience measurement

This website does not set any cookies.

To know how many people visit it and what they look at, I use Umami, a cookie-free audience measurement tool. It counts visits anonymously: page viewed, referring website, type of device, country. It does not keep your IP address and cannot be used to identify you or follow you from one website to another.

The fonts and animations are hosted on the website itself.

The Cal.com calendar only loads if you click “Book a call”. Cal.com may then use its own cookies: see its privacy policy.

Cloudflare, which hosts the website, records technical connection data (IP address, browser) to protect it and keep it running.

Your rights

You can ask to access your data, correct it, delete it, restrict its use, receive a copy of it, or object to its use. Write to me at martin@propriatech.io: I will reply within one month.

If my answer does not satisfy you, you can lodge a complaint with the CNIL, the French data protection authority (cnil.fr).
