What this site stores, why, and above all everything it does not do.
In short: a single cookie, for audience measurement, and only with your consent; no advertising, no third-party services. Nothing you do here is passed on to a third party. The site counts its page views on its own server, without ever storing your IP address. Your display settings stay in your browser, on your device. Comments on the articles ask for no account and no email address, and are read before they are published.
The site sets a single cookie, and only if you accept it: a randomly drawn identifier, used to tell whether you come back from one day to the next, described below. Technically it is kept in your browser's storage rather than in a cookie, but the law treats it as a cookie, hence the question asked when you arrive. You can decline it without losing anything.
The site uses your browser's local storage, an area private to your device, to remember your display preferences. That information never leaves your device: it is not sent to the server, nor to anyone else. One exception: the measurement identifier, if you have accepted it.

vf-swipe, vf-launch | Moving from one page to another: the slide to the next page, the opening animation. Cleared when the tab closes. |
None of these values identifies you, and none contains personal data. You can erase them at any time by clearing site data in your browser settings: the site will work exactly the same, with its default settings.
Since version 0.38.0, the site also keeps in your browser a copy of the pages you have opened and of the files they are made of, so they stay readable without network, in particular when the site is installed as an app. That copy holds nothing but public pages of the site, it is never sent anywhere, and it goes with the rest when you clear the site data. The private page and the dashboard are never kept in it.
The fonts and display libraries the site uses are hosted here, not loaded from Google Fonts or a content delivery network. That is a deliberate choice: calls of that kind pass the visitor's IP address to a third party, on every page viewed, without their knowing. No page on this site does it.
Links to outside sites, such as Open Food Facts, the CIQUAL table or scientific publications, are only followed if you click them. Those sites then have their own privacy policy.
The site counts its page views, on its own server and without cookies: the page viewed, the day, the language, the type of device (phone, tablet, computer), the site you came from if any or the fact that you arrived by scanning the QR code of the home page, the country you connect from, and the city in France or the state or province in the United States and Canada. Your IP address is never stored: at the time of the visit, it is only used to look up that place, nothing more precise, and to compute a fingerprint, mixed with a key that changes every day, to count the visitors of a single day without any way of linking two days together. This data is passed on to no one, uses neither Google Analytics nor any outside service, and is deleted after 25 months.
If you accept, in the cookie box or in Preferences, a randomly drawn identifier is also kept in your browser and sent with each page view, to tell whether you come back from one day to the next. It contains nothing about you. Your consent lasts 13 months, then the question comes back; you can withdraw it at any time in Preferences, which deletes the identifier.
At the foot of the articles, you can have your say. There is no account to create, no password, no email address to leave: a name if you want to give one, your text, and that is all. Your IP address is not stored here either: only a fingerprint of the day, mixed with a key drawn at random and erased after three days, keeps one device from flooding a page.
Your comment does not appear right away: it is read before it is published. Once published, the name you gave and your text are visible to everyone on the article's page, and stay there as long as the article exists. So put nothing in it you would not want seen in public, and bear in mind that a full name makes you recognisable: a first name, an initial or nothing at all does the job just as well. Any answer is published under your comment, on the page: nothing is sent to you, since nothing is asked in order to reach you.
Apart from the comments, the site collects no personal data: there is no record about you and no processing on which to exercise a right of access, correction or erasure. Because what the site stores sits on your device, you keep full control of it.
A comment, on the other hand, holds whatever you put in it. To read it again, correct it or have it erased, write to contact@vraifood.com giving the page and the name you signed it with: it will be done.
For any question, you can write to contact@vraifood.com.
