This policy explains what personal data we process, why, who may receive it, and the rights you have under the GDPR.

2. What we collect

  • Activity data: your progress, results and achievements on labs and academy content, and any ratings you leave.
  • Technical data needed to run and secure the service, including your IP address and essential cookies.

We do not sell your data, do not use it for advertising or tracking, and do not make automated decisions that produce legal or similarly significant effects about you.

3. Why, and on what legal basis

We may also disclose data where required by law.

5. International transfers

Our service is operated from the European Union. Some processing may take place outside the European Economic Area, including in the United States, where part of the lab infrastructure runs. Where data is transferred outside the EEA, the transfer is covered by appropriate safeguards, such as the European Commission’s Standard Contractual Clauses or an adequacy decision.

To exercise them, email [email protected] or delete your account from your settings. You may also lodge a complaint with the French supervisory authority, the CNIL.
