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.
