Visit statistics (Google Analytics)

Purpose: measuring the website's audience (pages viewed, where visits come from) in order to improve it. No advertising is linked to these statistics.
Prior consent: Google Analytics only loads after you click "Accept" in the banner. Without your consent, no statistics cookie is set.
Cookies: _ga and _ga_<identifier>, set by Google to tell visitors apart, lasting 2 years at most. The statistics are kept for 14 months in Google Analytics, then deleted.
Transfer outside the European Union: the data is processed by Google, some of whose servers are in the United States, under the EU–US Data Privacy Framework.
Withdrawing consent: at any time, with the "Cookies" link at the bottom of every page. The _ga cookies are then deleted.

Contact form

Data collected: your name, your email address, and the subject and text of your message.
Purpose: replying to you, and nothing else. Your data is neither sold nor used for marketing.
Address check: your message waits on the server until you click the link sent to you by email. It is deleted from the server no later than 48 hours after you confirm, or after 48 hours without confirmation.
Abuse protection: the number of messages is limited per IP address (over one hour) and per email address (over one day). These counters only hold timestamps, stored under a fingerprint from which the address cannot be recovered, and serve no other purpose.
Retention: once confirmed, the message is forwarded to me by email and stays in my mailbox for as long as our exchange lasts.

Comments

Published data: your name and your comment, with its date.
Data not published: your email address, used only to confirm your comment and to let you know when it goes live. Your IP address is used only to limit the number of messages.
Legal basis: your consent, given by ticking the box on the form.
Retention: at most 48 hours awaiting your confirmation, at most 30 days awaiting review, then for as long as the comment is online. A rejected comment is deleted straight away.
Removal: at any time, with the link in the email telling you the comment is live, or by writing to me using the contact form. The comment is then deleted.

Article ratings

Data stored: the rating you give (from 1 to 5) and its date, stored under a fingerprint computed from your IP address and the article. The IP address is never stored, and it cannot be recovered from the fingerprint.
Purpose: counting only one rating per person and per article, and showing the average. The number of ratings sent is also limited per IP address over one hour, in the same way as for the contact form.
Legal basis: legitimate interest, so that the averages shown are reliable.
Retention: the fingerprint is deleted after 12 months. The rating then only counts in the article's anonymous total.
Cookies: none. Your browser keeps the rating you gave (local storage) to show the stars again; it is erased along with this website's data in your browser.

"My passions: the latest" and artificial intelligence

Assisted writing: the posts in the "My passions: the latest" section are written with the help of an artificial intelligence tool (Claude, by Anthropic), from public sources cited at the end of each article. A notice says so on every article.
Human review: every article is read, corrected where needed and approved by me before publication, and I take editorial responsibility for it. The "My view" paragraph expresses my personal opinion.
Personal data: none. The tool only receives public content (the sources) and writing instructions; no data about the site's visitors is passed to it.
Sources and rights: facts are summarised in my own words, and quotations are short, in quotation marks and attributed. Any images are under a free licence or made available by their authors (ESA, NASA…), with their credit. A rights holder may ask for a correction or removal through the contact form.
Languages: the section is published in French and English.

Your rights

Under the GDPR, you can access your data, have it corrected or erased, object to its processing or ask for it to be restricted. To exercise these rights, write to me using the contact form. If you believe your rights are not being respected, you can lodge a complaint with the CNIL, the French data protection authority (cnil.fr).
