What to write about
- Something's broken — a name that doesn't fit, a worksheet that prints oddly. Tell us the name you typed and what device you used; that's usually enough for us to reproduce it.
- An idea — a style, a size, a use case we haven't thought of. Suggestions genuinely shape what gets added.
- Privacy questions — anything in our privacy notice you'd like explained further.
- Schools & classrooms — using TraceCub with a class? We'd love to hear how it went.
