Cookie Policy
DRAFT — to be reviewed by a lawyer before publication. Last updated: 2026-10-24
We use only what the service needs to work. No analytics, no advertising, no tracking across websites. LAUNCH BLOCKER: publish this paragraph only after fonts and scripts are served from our own servers That is why there is no cookie banner: cookies that are strictly necessary, or that remember a choice you made yourself, do not require consent (Art. 5(3) ePrivacy Directive and its national implementations).
| Cookie | What for | Type | Kept for |
|---|---|---|---|
dk_s | keeps you logged in | strictly necessary | 30 days or until you log out |
th_t | opens your own workspace (tells the service which account's data to show) | strictly necessary | 30 days |
th_o | administration session of the service operator's staff (not set for customers) | strictly necessary | 1 day |
dk_as | test mode for your organisation's administrator (viewing the service as one of your users; read-only, logged) | strictly necessary | 1 day |
dk_lang | remembers the interface language you chose | functional, set at your request | 1 year |
Browser storage. The service also stores interface preferences in your browser (theme, layout, pen settings, chosen formula sheet, voice and character set). They never contain students' personal data and are not sent to anyone.
Changes. If we ever add analytics or any cookie that needs consent, we will ask for consent first and update this page.
