This page lists the cookies the Platform stores on your device, what each one does, and how long it lasts. We only use cookies that are strictly necessary to make the Platform work, a single cookie that remembers your choice on the cookie banner, and — only if you pick one — a cookie that remembers your colour theme.
Strictly necessary
These cookies are essential to operate the Platform. They do not require consent under the ePrivacy Directive because removing them would prevent the service from functioning.
| Name | Purpose | Lifetime |
|---|---|---|
IWOSESSID | Session identifier — keeps you logged in across pages. | Session |
cookie_consent | Remembers that you have acknowledged the cookie banner. | 1 year |
| CSRF tokens | Protect form submissions from cross-site request forgery. | Session |
Preferences
This cookie is set only when you choose Light or Dark with the theme switch at the top of the page. It holds nothing but that choice, and it is shared by this website and the documentation sites so the choice follows you. Choosing Auto removes it, and the page follows your device's own light or dark setting again.
| Name | Purpose | Lifetime |
|---|---|---|
iwo_theme | Remembers whether you chose the light or the dark theme. | 1 year |
Optional
We do not currently use analytics, advertising, or third-party tracking cookies. If that changes, we will update this page and ask for your consent before any optional cookie is set.
Changing your choice
You can clear the cookie_consent cookie at any time through your browser settings to see the
banner again. Setting the theme switch back to Auto removes the iwo_theme cookie. The
strictly necessary cookies cannot be opted out of without losing the ability to log in.
