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.

Nothing leaves your device

We are not asking you to take our word for it. We are showing you how to check for yourself, in under three minutes, that nothing you write leaves your device.

The principle

There is nobody to send it to

A letter is written here in several steps: choosing a family of letter, answering a few questions, watching the text take shape. All of it happens in the page open on your screen.

This site is a set of files served as they are: behind it there is no code running on a server to receive anything at all. The template you choose and the list of its questions are already loaded into the page by the time it opens. Nothing needs to be asked for again while you write, and what you type has nowhere to go.

This is not a promise to be taken on trust. The rest of this page says how to check it for yourself, with the tools already installed in your browser.

A check, not a matter of trust

Open your browser's developer tools and look at what the page actually asks for: that is exactly what the banner at the top of this site already invites you to do, for itself as much as for any of its pages.

Three minutes is enough

How to check

The same method works on any page of this site, not only this one.

01

Open the developer tools

The F12 key, or right-click anywhere on the page and choose “Inspect”. Every recent browser has them built in, with nothing to install.

02

Go to the Network tab

That is the tab that lists, live, every request the page sends or receives.

03

Reload the page

The list fills up once: the page, its style sheet, its fonts, its script. That is all it takes to display it.

04

Fill in the workshop's form

Choose a family of letter, answer the questions as you would for a real letter, until you see it written on the screen.

05

Watch the list while you write

No line is added to it. What you type triggers no request: there is nobody to send it to.

One more line in that list, at the moment you type an answer, would be proof that something is going somewhere. There is none.

The heart of this page

Three columns, one truth each

Three things that get confused far too often: what this site does not do, what it does without telling anybody, and what a host receives in any case, on this site as on any other.

What this site does with what you type, and what the host inevitably sees
What this site does not doWhat it does in your browserWhat the host inevitably sees
The content of your letter: your answers, the subject, the dates, the name of the recipient.It is assembled in your browser, from the templates already loaded with the page.Nothing. That data is never transmitted: it exists only on your device.
Your draft as you write it.It is kept in the browser's local storage, on this device, until you click “Erase”.Nothing. Local storage never leaves the device that wrote it.
An account, a password, an address to hand over.Nothing: none of those exists on this site, there is nothing to create and nothing to remember.Nothing, since there is nothing of the kind to see.
A trace connecting today's visit to another visit.Nothing: no audience measurement, no identifier placed to recognise you from one time to the next.The address the request comes from, and the address of the page requested: what every server in the world receives with every request, this one like all the others.

Why the last column exists

A site claiming that nothing at all ever reaches its host would be lying. Requesting a page on the web, any page, means requesting it from a server: that server inevitably receives the address the request comes from and the address of the page requested. That is how the web works, not a choice this site made.

What this site does not do, on the other hand, is add anything to that minimal list. Not one line of your form is in it. No identifier connects two of your visits. Nothing counts what you wrote, or how long you spent writing it.

The guarantee stops at the device

What this site guarantees holds on the device you are using, and no further. On a machine other people will use after you, in a library, an internet café or a media library, a draft kept locally stays readable by the next person until it has been erased.

What the “Erase” button really does

The workshop's “Erase” button empties the form, deletes the draft kept on the device and goes back to the first question: nothing of it is left on that machine afterwards.

On a shared machine, the move that protects you is the same as for any other site: click “Erase” before you leave, or write from a private browsing window, which records nothing at all from the outset.

Checked: now write your letter

The workshop assembles your letter in this very page, without ever leaving it.
