Privacy Notice

wtf is Econometrics (“we”, “us”) is the data controller for any personal data collected through this site. We are based in Norway and can be reached at benjamin.mork@me.com.

We store your lesson-progress locally in your browser using a small cookie and browser storage managed by a lightweight state-management library. The legal basis for this processing is your explicit consent, which we ask for the first time you visit. The cookie remains until you clear your browser data or withdraw consent; no progress data is sent to our servers.

We partner with a limited number of third-party advertising providers that display occasional interstitial adverts. These providers may place their own cookies or similar identifiers to deliver and measure ads. We ask for a separate opt-in before any advertising cookies are set. You can withdraw consent at any time via the “Cookie settings” link in the footer.

We do not combine progress data with ad-network data, do not create behavioural profiles, and do not sell any personal information.

Under the GDPR you have the right to access, correct, delete or restrict the processing of your personal data, and to lodge a complaint with your local supervisory authority. Send any privacy-related request to the email address above; we answer within one month.

This notice may change as our product evolves. We will post any substantial changes here and, where appropriate, request a fresh consent.
