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.
How do I share files and photos with my class?
Open the class and go to the Files or Photos tab, then tap "Share a file" or "Share photos" — or use the paperclip next to the message box. The app asks you to confirm before uploading. Teachers and students can both share. Files can be up to 20 MB, and photos are compressed automatically. You need to be signed into iCloud.
How do I delete, or pin, a file, photo or message?
Tap the ✕ on any file or photo you can delete; for a message, press and hold it and choose "Delete message". You always get a confirmation first. Everyone can delete their own items; teachers can remove anything from their own class. Teachers can also pin files and photos (press and hold, then "Pin"): pinned items appear in the card at the top of that tab.
How do I report content or hide a person?
Press and hold the message, file or photo and choose "Report" — it opens an email to us with the details — or "Hide everything from this person" to stop seeing their content on your device. You can show hidden people again in Settings → Hidden people. We review every report and remove content that breaks our Terms.
Why can't I share a file or photo?
Check that your device is signed into iCloud (Settings → your name), that you have an internet connection, and that the file is under 20 MB. If it keeps failing, email us with the file type and size.
Can I move the AI Assistant button?
Yes. Press and drag it anywhere along the screen: it snaps to the nearest edge and remembers its position. Tap its ✕ to hide it until you open the assistant again from the header.
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). You can delete your own messages, files and photos at any time. To clear your own device, go to Settings → "Erase my data from this device". For removal of other cloud content, email us.
