Privacy
Everything is calculated on your device. Tetrarcana receives nothing of what you enter.
What the site does not do
No account, no cookies, no advertising trackers, no audience measurement.
What you enter
Your question, your date, time and place of birth, your floor plans and your notes stay in the memory of the open page. They are never sent to a server and are not kept from one visit to the next: closing or reloading the page clears them.
The files you download stay on your device. It is up to you to keep or delete them.
Phone compass
The compass is read only at your request, on your device. Its reading is neither stored nor transmitted.
Offline use
To work offline, the site keeps a copy of its own pages on your device. This copy contains none of your data. You can remove it by clearing the site’s data in your browser.
Hosting
The host, Cloudflare, processes the technical connection data — IP address, date, page requested — needed to deliver the pages and protect the site. Tetrarcana adds no tracking tool to it.
Your rights
Tetrarcana holds no data about you: there is therefore nothing to consult, correct or erase on its side. For technical connection data, refer to the host’s privacy policy.
