Change log

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

• 2026-09-11
  • We've expanded the Privacy Policy to cover analytics and advertising tools used or planned for hackArcana, including Google Analytics 4, Google Ads, Meta Pixel, LinkedIn Insight Tag and Reddit Pixel, as well as technical tag management through Google Tag Manager.
  • We've added information about possible server-to-server integrations and enhanced matching features, including Meta Conversions API, Reddit Conversions API, LinkedIn Conversions API, Google Enhanced Conversions and related Advanced/Enhanced Matching features.
  • We've clarified that external analytics and marketing tracking applies only to the publicly accessible part of hackarcana.com and does not cover private or internal areas of the platform.
  • We've added details about the website events that may be measured, including page and offer views, sign-ups, adding products to the cart, starting checkout and completing a purchase.
  • We've introduced separate consent categories for analytics and marketing tools. Optional external tools are activated only after the relevant consent has been given, and consent can be changed or withdrawn through Cookie Settings.
  • We've added information about conversion measurement, campaign attribution and optimisation, remarketing, audience creation and related profiling.
  • We've expanded the section on our internal analytics dashboard, including the types of data analysed, logged-in/logged-out status and how user identifiers are displayed and handled.
  • We've added information about the possible use of an email address to contact a user regarding an unfinished purchase, where the required consent for electronic communication is available.
  • We've expanded information about data recipients, international data transfers and the types of identifiers that may be shared with advertising platforms when server-to-server integrations or enhanced matching features are used.
  • We've updated the Cookie Policy and cookie table to include analytics and marketing technologies covered by the new policy.
  • We've updated the timeline of accounting document retention to be aligned with Swiss law.

• 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.
