Prosus.md is a free educational site for executives experimenting with AI tooling. We collect a small amount of anonymous usage data to find friction points and improve the course. This page explains exactly what that means.
What we collect — only if you accept
When the cookie banner is shown and you choose Accept, your browser stores two anonymous identifiers and we begin recording events to our database:
- Visitor ID— a random UUID stored in your browser's
localStorage. It identifies the same browser across visits but is not linked to your name, email, or any external account. - Session ID — a random UUID stored in
sessionStorage, scoped to a single browser tab. It is discarded when the tab closes. - Session cookie —
prosus_session, an HttpOnly, Secure, SameSite=Strict cookie containing a short-lived HMAC-signed timestamp (2-hour expiry). It exists so our event API can verify requests came from a real session on this site. - Event records— clicks, page views, chat interactions, and your consent choice. Each event captures the page path, an exercise slug if you're on a lesson, the element you clicked (tag, link, button text), and a timestamp.
- Browser user-agent — sent with each event so we can tell, in aggregate, which browsers people are using.
What we don't collect
- No name, email address, or account information.
- No IP address is persisted to our database. It reaches our server in the request headers but is not stored alongside events.
- No third-party advertising cookies, no cross-site tracking, no fingerprinting.
- No content of any chat conversations is sold or shared.
If you decline
We record the fact that you declined (as a one-off, throw-away UUID so decline-rates can be measured), and then stop. No persistent visitor ID is created, no further events are stored, and the consent banner will not show again on this device.
Where the data lives
Events are stored in a serverless PostgreSQL database (Neon). The schema is append-only: we never edit or merge event rows. We can, however, purge events on request — see Your rights below.
We also use Vercel Analytics for aggregate page-view metrics. Vercel processes data on our behalf and does not set tracking cookies.
Your rights
You can revoke consent at any time by clearing site data for this domain in your browser. To request deletion of events linked to a specific visitor ID, or to ask what we hold, email communications@prosus.com. Under GDPR you also have the right to lodge a complaint with your national data protection authority.
