Frequently asked questions

How do students join a class?

Ask the teacher for the class code (like NZX-45L) and enter it in "Join a class" — or scan the class QR the teacher shows, sends or prints. Joining is free and there is no limit on class size.

How does QR attendance work?

Each student opens "Show my attendance QR" — a personal code that renews every 30 seconds, so screenshots can't be reused. The teacher taps "Scan today's attendance" and points the camera at each student's screen. Attendance is assigned automatically to the current day, and both sides can review it later in the Attendance calendar.

What does it cost?

UDojo is free for students. Teachers create a class with a one-time purchase of USD 1.99 (or the equivalent shown for your region) — no subscriptions, no recurring charges. The number of repetitions is set at creation and can't be changed afterwards; to extend or repeat a course, create a new class.

How do refunds work?

Purchases are processed by Apple through your App Store account, so refund requests are handled by Apple: visit reportaproblem.apple.com and sign in with your Apple Account.

Why can't I join with a code?

Check three things: the code is typed exactly as shared, your device is signed into iCloud (Settings → your name), and you have an internet connection. Newly created classes can take a minute to become searchable.

How do I delete my data?

Teachers can delete a class from Edit Class (this removes it for everyone and cannot be undone). To clear your own device, go to Settings → "Erase my data from this device". For removal of specific cloud content, email us.
