Change log

This change log contains the most important changes between versions of the Policy.

• 2026-04-06
  • Due to the introduction of exercises (on hackArcana) using a built-in code editor, we have added a new category of "cookies" (local storage) that allow us to save the student's code in the browser (autosave). Thanks to this refreshing the exercise page no longer results in losing previously entered progress. "Cookies" from this category will also be used in other exercises for similar purposes. They are not used for tracking purposes and, by design, do not store any sensitive data.
  • In the previous version, Brevo was listed specifically for newsletter distribution. In the new version, we have expanded this to allow the use of Brevo for other non-newsletter-related mailings as well.
  • We've removed Mailjet (newsletter sending company) from the privacy policy. We had them as a fallback plan, but never actually used them.

• 2026-03-16
  • We've unified the Privacy Policy between our company's website and hackArcana website to make things simpler.

• 2024-07-12
  • We've added info about the following companies we're using for sending mails (including newsletters) to the Policy: GetResponse, Scaleway, MailJet.
