Launched a reading-streak tracker for my Year 8 class
Thirty students, one streak each, no accounts to manage.
Students log the minutes they read, the class sees a shared total, and I see who has quietly stopped. No personal data beyond a first name and a class code, which was the only way the school would let me use it.
Cursor built the whole login-free flow around magic class codes after I explained why real accounts were off the table. The surprise was the streak reset. My first version broke every streak at midnight UTC, so a whole class lost theirs over one weekend.
