BlockAxis does not ask for an account or store your calculator inputs on a server. Your language preference is stored locally in your browser. Quiz answers remain in page memory and disappear when the page is reloaded.

Cloudflare Web Analytics measures visits, page views and page performance on blockaxis.net. This service does not use cookies or local storage to identify visitors. It receives technical connection and page information; our integration does not send calculator inputs, quiz answers, saved guides or correction drafts. Hosting infrastructure may separately process request information and access logs. External services apply their own privacy policies.

No optional advertising cookies are set by this site. You can clear the saved language choice with the control below.

The selected day or night appearance is saved in this browser, alongside the language preference. Quiz answers are processed locally and are not saved by the lesson quizzes. Clearing preferences restores the day appearance.

Optional educational videos are hosted by YouTube. A player connects to YouTube only after you select Load the video; the provider then receives connection information and applies its own privacy terms. You can use every lesson without loading a video.

The learning journey also stores mastered lessons and completion dates, review reminders, completed missions and your weekly goal in this browser. XP and badges are derived from that progress. Individual answer choices are not stored, but quiz success can update this progress. Use the learning dashboard controls to reset learning data; the preference button below only clears language and appearance.

Your learning data

Guides marked as read, favourites and the last guide opened are saved only in this browser, shared across the two languages. They do not sync across devices. Quiz answers, orientation answers, comparison scenarios and correction drafts remain in page memory.
