01What is a cookie?
A cookie is a small text file a website saves in your browser. Browser local storage (localStorage) can be used for similar purposes.
02Essential cookie and storage
These are needed for the site to work and do not depend on your consent.
- __Host-oky_sid (cookie): recognises your session securely after you sign in. Only the server can read it; it is removed when you sign out or the session expires.
- oky-theme (local storage): remembers your light or dark theme.
- oky-consent (local storage): remembers your cookie choice.
- oky-wz-draft (local storage): keeps your unfinished project builder answers on your device only.
03Measurement (optional)
If you allow it, we run a cookie-less measurement on our own server to understand how the site is used: which page was viewed and whether the project builder was started and completed. Nothing is stored on your device, and your browser’s Do Not Track / Global Privacy Control setting is respected. If you decline, measurement does not run at all.
04Marketing and third-party cookies
We use no advertising, retargeting or social media tracking cookies. If we ever decide to, we will update this page and ask for your consent first. Our infrastructure provider may set short-lived security cookies to protect the site against attacks.
05Changing your choices
Change your choice at any time from “Cookie preferences” at the bottom of every page. You can also delete or block cookies in your browser settings; if the essential cookie is blocked you cannot sign in.
