Common questions

Why does the App need the camera?

Luxdeck uses the camera as a light sensor. It reads image brightness and color in real time to compute a reading, then discards the frames. No photos are taken, stored, or uploaded.

What does “Uncalibrated” mean on a reading?

It tells you the reading is a relative estimate rather than an absolute, device-tuned measurement. It's part of being honest about what a phone camera can and can't do.

How do I cancel a subscription?

Open Settings on your iPhone, tap your name, then Subscriptions, and manage Luxdeck there. See our Terms for details.

Where is my data?

On your device. The App has no account and no server of ours. See the Privacy Policy.
