Privacy
Last updated: 22 September 2026
Opulart has no accounts, sets no cookies, and asks you for nothing. The works you keep stay in your own browser, on your own device.
The publisher does not know who you are and has no way of finding out. That is why there is no banner to accept when you arrive.
Opulart is published from France and governed by French law. The French version of this page is the authoritative one.
1. What your browser keeps
The site stores two things in your browser's local storage (the
localStorage feature). They never leave your device, are sent
to no one, and the publisher cannot read them.
opulart.favoris
the numbers of the works you have kept
opulart.langue
the display language you have chosen
These are not cookies: nothing is attached to your requests or sent to a server. They exist only to provide what you asked for, keeping a work and seeing the site in your language, which under article 82 of the French Data Protection Act means no prior consent is required.
To erase them, clear the site's data in your browser settings. Your collection will be lost, since it exists nowhere else.
2. Audience measurement
The site uses Cloudflare Web Analytics to know how many people visit it.
What is recorded:
- the number of page views and the address of the page viewed;
- country, device type, browser and operating system;
- the site you arrived from, if any;
- technical measurements of how fast the page loaded.
What is not done:
- no cookie is set, nothing is written to your browser;
- you are not tracked from one visit to the next, neither by IP address nor by any other fingerprint;
- no profile is built, and no data is sold or shared.
A "visit" is not an identified person: it is simply a page view arriving from another site. The resulting statistics are aggregated and cannot be traced back to you. They are used only by the publisher, to know whether anyone is reading the site.
3. Hosting
The site is served by Cloudflare, Inc. (United States), which processes your IP address in order to deliver pages and protect the site from attacks. This is a technical necessity common to every website, based on the publisher's legitimate interest in running and securing it.
The publisher has no access to these logs in any form that would identify you. For more: Cloudflare's privacy policy.
4. Other services your browser contacts
Displaying a page of Opulart makes your browser request files from other servers. Those servers therefore receive your IP address, as with any web page:
- image.opulart.com (Cloudflare): the thumbnails shown in the grid.
- wsrv.nl (Netherlands): the large images, when you open a work full screen.
- fonts.googleapis.com and fonts.gstatic.com (Google, United States): the site's two typefaces.
- the museum's own website, only if you click through to a work's record.
5. Your rights
The General Data Protection Regulation (GDPR) gives you rights of access, rectification, erasure, restriction and objection over your personal data.
Since Opulart keeps nothing that could identify you, the publisher cannot recognise you and has, in practice, nothing to disclose or erase (article 11 of the GDPR). You are welcome to write to contact@opulart.com with any question about this page.
If you believe your rights are not being respected, you may lodge a complaint with the French data protection authority, the CNIL.
6. Changes
This page describes the site as it works today. If the site changes, this page changes with it, and so does the date at the top.
