LuxFit: Room Light is the offline illumination calculator and LED placement planner that turns lighting physics into a calm, visual routine. Drag a light, watch the lux bloom.
Drag ceiling lights, spotlights and wall sconces onto a scaled 2D floor plan of your room.
See light spread, beam angles and fall-off across work planes and dark corners as you move things.
Enter square footage and purpose; get required total lumens for kitchen tasks or bedroom ambience.
Exact fixture counts and grid spacing, so no dark spots survive between your downlights.
Keep layouts for every room of an apartment or house, stored privately on your device.
Plan inside unfinished buildings and remote sites. No connection needed, ever.
💡 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.
Effective Date: October 2026
LuxFit: Room Light does not collect, store or transmit any data. Everything happens locally on your device.
Nothing. We do not collect personal information, usage data, device identifiers, location or any room measurements you enter.
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.
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.
LuxFit contains no analytics, advertising networks, trackers or third-party SDKs that gather data.
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.
The app is suitable for all ages. We do not knowingly collect information from anyone, including children under 13, in line with COPPA principles.
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.
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.
