This is an official ODERSA website. Here’s how you know

The official domain

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

Free, and no account

Everything is open straight away. No sign-up, no account, no password, no subscription, no advertising. Nothing is held back for those who pay, because there is nothing to pay 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.

Free to reuse

The content is published under the CC BY 4.0 licence. You may copy it, translate it, print it and pass it on, for your classes as much as for the people around you, on one condition only: credit ODERSA.

Privacy

Your data? We do not want it.

The simplest privacy policy there is: this site collects nothing. Not because a policy promises so, but because it is built that way.

No cookies. No trackers. No measurement tool in these pages. No request to any third-party server. This site collects, stores, and transmits no data. Never resold, never shared with a third party: there is literally nothing to sell.

That is also why there is no consent banner: there is nothing to consent to.

Check it yourself, in one minute

  1. Open your browser’s inspector: the F12 key, or right-click and choose “Inspect”.
  2. Go to the “Network” tab and reload the page.
  3. Look at the domain column: every request goes to this site, none leaves for anywhere else. Fonts, images, and scripts are all served from here.

Your settings stay with you

The settings panel (theme, text size, contrast, and so on) saves your preferences in your browser’s local storage, on your device. Nothing is sent anywhere: there is no server to receive them. The panel’s “Clear everything” button removes them in one move.

Offline mode

After your first visit, the site stays available offline thanks to a cache saved by your browser, on your device. That cache sends us nothing; you can clear it from your browser’s settings.

If you write to us

Your email address is used to reply to you, period. It enters no database, triggers no newsletter, and is never shared with third parties.

What the host sees

As with any site, the infrastructure that serves the pages (Cloudflare) technically processes requests in order to route them. We add no tracking of our own and consult no personally identifying logs.
