Your study time is saved to your account, so it follows you to every device.
Courses live inside a semester. Create the semester you're in now; you can add, rename and archive courses afterwards.
From the myStudies Stundenplan HS26, Semesterwoche 6–14. After a class ends it shows up on Track under “Classes to confirm”; nothing is counted until you confirm it. For each lecture, choose Attending or Not coming; for each course, choose the one exercise group you go to.
Rename what you see, e.g. Exercises → Übung. Comparisons keep grouping the same kind of work together.
One-off tasks show up for the whole group. Everyone ticks them off for themselves. These are separate from your personal tracking tasks on Track.
These rules add a new task every week automatically, for everyone. Each person's ticks stay private. Check release and due days against the course websites. Changes here apply to the whole group.
The group only ever sees averages. Nobody, you included, can see how long one particular person worked. Averages appear once at least 3 people have tracked time that week. Only the shared D-MAVT courses count, matched even if you renamed them; your extra subjects never do.
Studying now is the small bar at the top: who is tracking right now, on which course, since when and for how long. It's optional: only people who switch it on appear, and only they can see it. No weekly totals are shared.
