About Us

Made by people who love good light.

💡 We are a small team of designers, developers and weekend electricians who got tired of guessing how many downlights a room really needs.

🎯 Our mission is to make lighting physics friendly, so anyone can plan a space that looks beautiful and works for the task at hand.

🗺️ LuxFit gives you a drag-and-drop room canvas, a live lux heatmap, lumen targets for every room type and exact LED counts and spacing, all without a connection.

✨ Plan once, wire once, light it right.

Privacy Policy

Your rooms stay yours.

Effective Date: October 2026

LuxFit: Room Light does not collect, store or transmit any data. Everything happens locally on your device.

1. Information We Collect

Nothing. We do not collect personal information, usage data, device identifiers, location or any room measurements you enter.

2. How We Use Information

Because we hold no information, we do not use it, analyze it, share it or sell it. Your room layouts and lux calculations are used only by the app to show you results.

3. Data Storage

Saved layouts in your room journal live only in the app's local storage on your device. There is no cloud, no server and no sync.

4. Third-Party Services

LuxFit contains no analytics, advertising networks, trackers or third-party SDKs that gather data.

5. Data Security

Since nothing leaves your device, your projects are protected by your device's own security, such as its passcode and encryption. We recommend keeping your device updated.

6. Children's Privacy

The app is suitable for all ages. We do not knowingly collect information from anyone, including children under 13, in line with COPPA principles.

7. Your Control

You are fully in control. There are no accounts to create. Delete the app to remove all saved layouts permanently, or remove individual projects from the journal at any time.

8. Changes to This Policy

If we update this policy, the new version will appear in the app and on this page with a revised effective date. Our no-data-collection approach will not change quietly.
