Privacy Policy

🔒 What we collect

Nothing. Luma LED has no sign-up, no login and no user accounts. It contains no analytics, crash-reporting, advertising or tracking code, and it never sends anything to Cornish Technologies or any other company. We do not see, store, sell or share any information about you or how you use the app. Luma LED does not track you across other apps or websites.

📍 Where your settings live

Your presets, favorite looks, holiday schedule, groups and downlight layout are stored in two places you control: the app's storage on your phone, and your own lighting controller on your home network. When you use more than one phone, settings move directly between your phone and your controller over your Wi-Fi, never through the internet. Deleting the app removes its data from your phone. Resetting a controller removes the data stored on it.

📶 Local network access

iPhone asks permission for Luma LED to use your local network. The app uses it to find lighting controllers on your Wi-Fi, using standard Bonjour discovery, and to send them commands. The app talks only to controllers on your own network.

When you update a controller's firmware, the firmware file is already inside the app. It goes straight from your phone to your controller over Wi-Fi and is not downloaded from the internet.

Demo Lights, the built-in simulated controller, runs entirely on your phone and uses no network at all.

🌐 What your controller connects to

The app itself makes no internet connections. Your lighting controller, a separate device on your network, may connect to these public services:

• Internet time servers (pool.ntp.org), to know the date and time so the right holiday look plays.
• ESPN's public sports schedule service, only if you turn on sports teams. The controller asks for the schedule of the teams you chose so it can show team colors on game days. No personal information is sent.

Like any internet request, these services can see your home's public IP address. Their own privacy policies apply. Cornish Technologies receives nothing from these connections.

🗺️ Location

Luma LED never requests or uses your phone's location. If you turn on sunset timing, you type in a city or ZIP code. The app converts it to an approximate position using tables built into the app, and saves it only to your controller so it can work out sunset time.

🧒 Children's privacy

Luma LED is not directed at children and does not collect information from anyone of any age.

✉️ Changes and contact

If this policy changes, for example if a future version adds an optional feature that uses the internet, this page will be updated first with the change and a new effective date.
