What this site keeps in your browser

Four things, all of them settings you made yourself, all of them on your own machine. No cookies, no account, and nothing fetched from anybody else's server.

The short answer

This site has no login for readers, no database and no record of you. It sets no cookie: not on the front page, not on a course page, not on a clause page.

What it does keep is four small entries in your own browser's storage, so the page looks the way you left it and remembers which chapters you have finished. None of them is sent anywhere. Nothing on this site can read them except the pages of this site, in this browser.

That is also why there is no button here that says “Accept”. Nothing is being asked of you, because there is nothing to switch off — turn these off and the colour picker, the style picker and the chapter ticks stop working.

The four things it keeps

These are the real keys, exactly as they are written. You can see them yourself in your browser's developer tools, under Local Storage for this site.

The keyWhat it is forHow long it lasts
theme Which of the four colour schemes you picked in the bar at the top — Night, Paper, Blueprint or Terminal. Written only when you change that picker. Until you clear it. See below.
style Classic or Easy: how big the type runs and how much space each block gets. Written only when you change that picker. Until you clear it. See below.
sos-read: and a course name
for example sos-read:standards-overview
One entry per course you have read in. It holds the list of chapters whose questions you have all answered, which is what puts the tick beside a chapter. Written when you finish answering a chapter's questions. There is one entry per course, so a reader of three courses has three. Until you clear it. See below.
sos-notice That you pressed “I see” on the short notice about this page, so you are not shown it again on every visit. Written when you press that button. Until you clear it. See below.

How long they last, honestly

They last until you remove them. Browser storage of this kind carries no expiry date, and nothing on this site deletes it — so saying “thirty days” here would be a promise the code does not keep.

They also last per browser and per machine. The same site opened in a different browser, or on your phone, knows nothing about what you did here.

How to get rid of them

What it does not keep

Nothing is fetched from another server

Every part of a page on this site comes from this site: the stylesheet, the script, the four typefaces, the favicon, and every figure out of a standards document.

That matters because your browser has to hand over your address to any server it asks for a file. There is no font service here, no map, no video frame and no analytics — so no other company learns that you opened this page.

What still has to be written here

Three lines on this page are the operator's to write, not a session's, and they are not written yet.

The four keys above were read out of this site's own script on 4 August 2026, and the “no cookie” line was checked against the live site on the same day.
