Privacy

The site’s publisher (see the legal notice). Contact: our contact form.

We measure our audience with PostHog (PostHog Inc.), whose data is hosted in the European Union. It works without cookies or profiles: pages viewed, time spent, clicks on links and buttons, and a few actions on the maps and in 3D (chapter reached, filter, object chosen, language or instrument played, share). Never what you type.

Your IP address is used only to compute an anonymous identifier that changes every day (at PostHog) and to work out your country (at our host); it is not kept, and only the country code is passed on, never your city: we cannot identify you.

Legal basis: our legitimate interest in knowing what is read, within the consent exemption for audience measurement. Your browser’s “Do Not Track” or “Global Privacy Control” signal turns all measurement off.

Retention: 1 year; after that, they can no longer be viewed and may be deleted.

If you write to us, we receive your name, email address, subject and message, to answer you and for nothing else. We don’t publish them or pass them on to anyone.

The message reaches us through our host, in the European Union. It is kept for 90 days in our mail system, then deleted, and in our inbox for as long as it takes to handle your request. Technical logs, without the content of messages, are deleted after 30 days.

Legal basis: our legitimate interest in answering the messages we receive.

The site is hosted by Amazon Web Services, in the European Union (see the legal notice). Connections are encrypted (HTTPS).

No cookies. The site keeps your language choice in your browser’s local storage and, for the length of your visit, whether a tip has already been shown to you (session storage, erased when you close the tab). Nothing else without your consent.

No advertising, no embedded social network: share buttons are plain links that send nothing until you click. Fonts, maps, images, 3D models and recordings are served by the site itself.

PostHog and Amazon Web Services belong to US groups; the data we entrust to them is hosted in the European Union.

You can ask to access, correct or delete your data, or object to its processing, by writing to us through our contact form. You can also complain to your country’s data protection authority; in France, the CNIL (cnil.fr).
