Privacy and legal notice

Last updated: 3 November 2026

Legal notice

• Publisher and director of publication: Edgar Maucourant, as a private individual. Terra Tempora is a non-commercial, amateur project.
• Contact: privacy@terra-tempora.com
• Host: Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, United States. Phone: +1 (650) 319-8930.
• The code is public on GitHub. The sources of the maps and pictures, and their licences, are listed under Sources on the site.

What we collect, and why

Terra Tempora has no account, no advertising and no cookies. It collects as little as it can:

• Anonymous usage counts. To learn which parts of the site are used, the page sends counts such as the realms and periods viewed, searches that found nothing, the language, the kind of device and the country. There is no cookie, no visitor id and no IP address, so nothing identifies you. The counts are kept by Cloudflare for about 3 months.
• Your rough location. When the site opens, it asks Cloudflare which country and city your connection comes from, only to turn the globe towards you. Nothing is stored.
• Reports. When you report a problem, your message and what you were looking at are published as a public issue on GitHub, so the fix can be discussed in the open. Please keep personal details out of the message. Reports go through Cloudflare's anti-spam check (Turnstile) and are limited per connection to stop abuse; your IP address is used for this but not stored by us.
• Your email, if you leave it with a report. It is optional. It is encrypted in your browser before it is sent, and only the encrypted copy is kept, in the GitHub issue. Only the authors of Terra Tempora hold the key to read it. We use it only to tell you when your report is fixed, or to contact you about the fix if you ticked "I want to help", based on your consent, and delete it once the fix is done, after 2 years at most.
• Kind words. When you send a message from the Support pop-up, your message, the name and email you choose to give (both optional) and the site's language are emailed privately to the publisher through Cloudflare. They are not published. They stay in the publisher's mailbox (Gmail, by Google), and we delete one on request. Your email is used only to answer you. Like reports, they go through the anti-spam check and the limit per connection.
• Donations. The Ko-fi and GitHub Sponsors buttons are plain links: nothing loads from those sites until you follow one. A donation is handled entirely by Ko-fi or GitHub, under their own privacy policies; we only learn what they show us, such as the name you give them.
• In your browser. Your browser keeps your language, a few display choices, the last version of the site you saw (to tell you what is new) and a cache of Wikidata answers to load faster. They stay on your device and are never sent to us.

Who else is involved

• Cloudflare, Inc. serves the site, counts the visits and checks reports for spam.
• GitHub, Inc. stores the reports.
• Google LLC hosts the publisher's mailbox, where kind words and emails to the address above arrive.
• The Wikimedia Foundation serves the pictures and texts from Wikipedia, Wikidata and Wikimedia Commons, which your browser loads directly. See their privacy policy.

These companies are based in the United States. Cloudflare, GitHub and Google are certified under the EU–US Data Privacy Framework.

Your rights

You can ask to see, correct or delete your data, or withdraw your consent, at any time by writing to privacy@terra-tempora.com. If it is about a report, give its number or link so we can find it. If you think your rights are not respected, you can complain to the CNIL, the French data protection authority.
