Controller

Thorben Spanka is the data controller. Contact: hello@criticalquant.com. The postal address is available in the Legal Notice.

Labs and feedback

The labs run in your browser. CriticalQuant does not require an account, email address, password, or payment to use them.

The voluntary feedback feature sends only the answers and lab request you choose to the CriticalQuant feedback endpoint. It does not require an account or an email address. Please do not include private code, personal, employer, account, trading, or confidential data.

Service providers and retention

Hostinger provides website hosting and business email. These providers may process the technical and operational data needed to provide their services under their applicable data-protection terms.

Voluntary feedback records contain only the selected feedback answers, requested lab topic, an anonymous record identifier, and the time received. They are kept only as long as needed to improve the labs, then deleted or anonymised unless a longer retention period is required by law. A short-lived one-way network hash is used solely to limit abuse and is not stored with feedback records.

Your rights

You may request access, rectification, erasure, restriction, or portability of your personal data by emailing hello@criticalquant.com. You may also lodge a complaint with the Spanish Data Protection Agency (AEPD).

Cookies and measurement

CriticalQuant does not use advertising or analytics cookies on the public landing page or the labs. The labs store only voluntary learning-progress information locally in your browser so that your completed steps can be shown on the same device. You can clear this local browser data at any time.
