Face Recognition Check-In

Some studios offer face recognition as a convenient check-in option. Here's what it does, what data it stores, and how you can opt out at any time.

How It Works

1
Stand in front of the kiosk
When the face tab is active, the kiosk camera opens. A message on screen lets you know face recognition is being used.
2
Your face is scanned automatically
The system looks for a face in the camera view. When it detects one, it creates a short mathematical vector (128 numbers) from the shape of your face features.
3
You are matched to your account
That vector is compared against your enrolled reference vectors. If there's a confident match, the kiosk shows your name and asks you to confirm.
4
Tap 'Yes' to check in
Tap "Yes, Check In" to complete your check-in. If the name shown isn't you, tap "Not me" — the check-in is cancelled and no attendance is recorded.

Your Privacy

1
No photos are stored
The system never saves photos or video of your face. Only the 128-number mathematical vector is stored — this cannot be reverse-engineered into a photo.
2
Enrollment requires your consent
You (or your parent/guardian) must give consent before any face data is captured. Staff cannot enroll you without your permission.
3
Your data stays with your studio
Face data is isolated to your studio's account. MyDojang does not use or share biometric data across studios or for any other purpose.
4
You can opt out at any time
Ask a staff member to delete your face data. It is removed immediately and you can use other check-in methods (QR code, PIN, or name lookup) instead.

Opting Out

1
Speak to a staff member
Tell a staff member you'd like your face data removed. They can delete it from your student profile immediately.
2
What happens when data is deleted
All stored face embeddings are permanently deleted. Face recognition is disabled for your account. Your other check-in methods continue to work normally.
3
Re-enrolling later
If you change your mind, you can be re-enrolled at any time. Staff will ask for your consent again and capture new reference shots.

What if the system doesn't recognize me? Use your QR code, PIN, or name search to check in instead. Ask staff about re-enrolling with better lighting or more shots.
What if someone else is matched to my account? Tap "Not me" on the confirm screen — no check-in is recorded. Tell staff so they can investigate.
Is this required? No. Face recognition is always optional. You can use QR code, PIN, or name lookup instead.
Can the studio see my face? No. Only the 128-number mathematical embedding is stored — not a photo. Staff cannot view or download your facial data in any readable form.
