This site is internal study material intended only for students enrolled in the course. Access is given to you personally, for learning within the course only.
Do not pass on, share or publish the link to the site to anyone who is not enrolled in the course — not in groups, not on social networks and not by any other means. The content was developed and adapted specifically for this course, and any use of it outside your studies (including copying, redistribution or commercial use) is forbidden without explicit prior permission.
If you find out that the link has reached someone who is not a student in the course, please let us know.
Sign-up and login: access to the site requires a personal account — sign-up with an email and a password. Sign-up includes real email verification: before the account is created, a 6-digit code is sent to the address you entered, and you need to enter it on the site to complete the sign-up — so an address that does not really belong to you cannot be registered. Your password is stored on our server in encrypted form (a hash) only — never as plain text, and it is not accessible to us or to anyone else.
Visit tracking: every time you open a page on the site, a visit linked to your account is recorded (email, page, time) — so we can know which students open the course material, how often, when, and roughly how long they spent on which pages. In addition, the site shows the course instructor/manager who is online right now (in real time), through a secured admin page (login with a one-time code sent by email, not a fixed password). This data is available only to the course instructor/manager and is not shown to other students. We do not sell or share your information with third parties.
Progress tracking: marking lessons as “complete” is saved first locally in your browser (localStorage), and is also synced to the server and linked to your account — so the course instructor/manager can see on the admin page how many lessons each student has completed. If you clear your browser data or move to another computer, the progress saved on the server (linked to your account) is not deleted, even if the local display is reset.
Course chat: the messages you write in the course chat are saved on our server and are visible to every logged-in student, next to the display name you chose in your profile. Until you choose a name, logged-in students see your full email address. The display name, description and color in your profile are visible to every logged-in student, and you can change or remove them at any time. You can delete your own messages, and the course instructor/manager can delete any message.
For questions about this policy, or to request removal of access — contact us through the details on the course site.
