This site is an official ODERSA site. Here is how to find out

The official domain

The address of this site ends inodersa.org. Every service of the association lives on a subdomain of odersa.org and nowhere else. If the address in your browser bar does not end in odersa.org, this site is not ours.

Free, and no account

Everything is open straight away. No registration, no account, no password, no subscription, no advertising. Nothing is reserved for those who pay, since nothing is paid for.

No data collected

This site does not follow you: no tracker, no tracking cookie, no measurement tool built into these pages, and nothing measured on your device. Our host counts requests in aggregate, as any server that answers does: a total, never a profile. You do not have to take our word for it: open your browser’s developer tools, go to the Network tab, and reload the page. You will see the full list of what the site asks for. Everything comes from odersa.org, nothing goes anywhere else.

Freely licensed content

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and redistribute it, for your lessons as for your family, on the single condition that you credit ODERSA.

Display settings

These settings need JavaScript. Without it, the page stays readable as it is: the text follows the size chosen in your browser.

Report an error

A symbol that does not say what its label announces, a wrong word, a board that prints badly, a licence badly credited: say so, and it will be put right.

The message is sent by your own email program. We keep only what you write, for as long as it takes to put things right.

If your browser does not open an email program, write directly to speak@odersa.org, giving the address of the page. For the administration of the association, the address is contact@odersa.org.

What is most useful to us

On a communication tool, an error is not just a typing mistake: it can make someone say the opposite of what they meant. These reports therefore count double.

What helps to put it right quickly
