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.

What this site borrows, and what it owes nobody

Here, plainly, is what this site borrows from others, and what it owes nobody. The list is short: that is precisely what makes it checkable.

The typefaces

Two type families, embedded with their licence

The headings on this site are set in Source Serif 4, the body text in Public Sans. Both families are embedded in the repository as woff2: no request goes out to an online font service, and that can be checked like everything else, in the network inspector.

Both typefaces are published under the SIL Open Font License 1.1, a free licence allowing use, modification and redistribution, including inside another project. Public Sans is the typeface of the United States federal design system, the USWDS: the kinship is owned, not hidden.

The banner

An approach borrowed, never a line of code

The black banner at the top of every page takes up an approach, not code: a plain strip that states something, and a detail that gives you the means to check rather than asking you to believe it. That logic is the logic of the official USWDS banner, a United States federal government work and therefore in the public domain.

Its black colour is taken from the strip on the United Kingdom government site, GOV.UK. Nothing has been copied from either one: this site's banner is written for it, in native HTML, with no dependency and no measurement script.

No dependencies

What this site owes nobody

This is what makes the promise of the trust banner checkable: every point can be verified in the network inspector, with no need to take this text on trust.

  • No library: the site is written in native HTML, CSS and JavaScript, and the generator that builds it is a Node script with not one installed dependency.
  • No CDN: no resource is fetched from a third-party domain.
  • No remote fonts: the two families above are embedded in the repository, never loaded from an outside service.
  • No measurement tool in these pages: no tracker, no tracking cookie, no embedded visit counter.
  • No third-party images: the site's images are freely licensed, embedded and credited, and not one is fetched from an outside domain.

The writing

An institutional voice, dated references

The texts on this site are written in the name of ODERSA, never in the name of one person: it is the association speaking, as in the rest of its publications.

Every legal reference cited in a letter template was taken from its official public source, on the date shown beside it. The collection holds 16 references checked that way so far: the detail, source by source, is on the page devoted to them.

The images

The photographs, and where they come from

8 photographs, all freely licensed, all embedded in the site.

No image is fetched from an outside service: they sit inside the site, and that is what lets the trust banner promise that no request goes out. A photograph loaded from a third-party domain would tell that domain which page you are reading.

For each one, the licence was read at its source page, and the date it was read is in the table. The link in the last column leads to that page: you can check for yourself, without believing us. All 8 out of 8 have been.

No licence forbidding commercial use or modification gets in here: this site's content is under CC BY 4.0 and has to stay reusable, commercially included. A single image under a more restrictive licence would break that promise for the whole site.
