Privacy policy

The site runs on its own server in a data centre in the European Union. When a page is requested, the server processes technically necessary information: IP address, time, the address requested, the referring page and the browser identifier. These logs serve the secure operation of the site and the defence against attacks, and are deleted after a short time. The legal basis is our legitimate interest in secure operation (Art. 6(1)(f) GDPR).

To understand which pages are being read, we run our own statistics. They set no cookies, use no third-party services and store no IP addresses. An identifier is formed from the IP address and browser identifier; it changes every day and does not allow any conclusions about individuals. Only the country, the type of device and the pages visited are stored. We do not use Google Analytics or comparable services.

We set no cookies for visitors. A cookie is used only when logging in to the administration area. The Sommelier keeps the current conversation in your browser's storage (sessionStorage) so that it survives when you move between pages; it disappears when you close the tab. Your star rating of a page is remembered locally by the browser (localStorage), so that you can see it again.

Questions put to the Sommelier are sent to Anthropic PBC (USA), the provider of the AI model we use, so that they can be answered. What is sent is your question, the history of the current conversation and extracts from our pages, but no names or contact details. Please do not enter any personal data in the Sommelier. We store questions and answers in order to improve the Sommelier; to limit misuse, a value is formed from the IP address that changes every month. The transfer to the USA relies on the EU Commission's standard contractual clauses.

If you send us a message, a photo or a document through "Share your knowledge" or a producer's personal page, we store this information in order to review it and, where appropriate, incorporate it into the site. Your name and email address are optional and are used only for follow-up questions. Messages in other languages are machine-translated (Anthropic) for internal handling. We publish photos only if you have expressly agreed to this. The legal basis is your consent (Art. 6(1)(a) GDPR), which you can withdraw at any time.

When you give a star rating, we store the stars, the page, the language and a value formed from your IP address and browser identifier, which changes every year. It prevents multiple ratings and does not allow any conclusions about you as a person.

For maps we use OpenStreetMap. When a map is displayed, your browser loads map tiles from the servers of the OpenStreetMap Foundation and the Leaflet map library from unpkg.com; your IP address is transmitted to these services in the process. Links such as "open in Google Maps" only take you to Google once you click them.

Champagner.com takes part in Amazon's affiliate programme. For some champagnes, a link leads to Amazon; only when you click it does Amazon set its own cookies, so that a purchase can be attributed to our site. Amazon is responsible for this processing.

All fonts are hosted on our own server. No fonts are loaded from Google or any other provider.

You have the right to access, rectification, erasure and restriction of the processing of your data, to data portability, and the right to object to processing. To do so, simply contact us by email. You can also lodge a complaint with a data protection supervisory authority.
