Question 1

How does the online mirror work?

Accepted Answer

It uses your device's webcam through the browser's built-in getUserMedia API. When you click Start, the browser asks for camera permission and shows a live, horizontally flipped video feed — exactly like looking into a real mirror.

Question 2

Is the webcam video uploaded or recorded?

Accepted Answer

No. The video stream stays entirely inside your browser. It is never uploaded to any server, never recorded, and never stored. The snapshots you take are saved directly to your own device.

Question 3

Why is my mirror black or not showing anything?

Accepted Answer

The most common causes are: 1) camera permission was denied — click the camera icon in the address bar to allow it; 2) another app (Zoom, Teams, etc.) is using the camera — close it and retry; 3) no webcam is connected or it is disabled in your system settings.

Question 4

Does the online mirror work on my phone?

Accepted Answer

Yes. On a smartphone it automatically uses the front-facing camera so you can use it as a pocket mirror for quick appearance checks, makeup touch-ups or contact lenses — no app install required.
