Does a LiDAR scan save photos of my home?

No — what HouseSense saves after a scan is a list of walls, doors, windows and furniture with measurements attached, not the video from the camera.

What the camera does, and what actually gets kept

During a LiDAR scan, the iPhone uses both the laser rangefinder and the camera. The laser measures the distance to surfaces many times a second; the camera helps keep track of where the phone itself is, and helps recognise whether something is a door, a window or a table. That's what's happening while you scan.

When the scan finishes, the result isn't a video clip. It's a structured list: a set of walls with position, direction, length and height; a set of openings with their size and position on the wall; and a set of recognised objects with a type and a bounding box around them. That list is what HouseSense saves — and it's also what the floor plan, the areas and the 3D model are built from.

In practice, that means a saved scan can't be "played back" like a tour. There are no images in it to play. You can see the room's shape, not the room's contents.

Why the 3D model doesn't look like your home

Many people are surprised that the 3D model of their home looks clean and schematic rather than photorealistic. That isn't a limitation waiting to be fixed — it's the direct consequence of no images being saved. The walls are drawn as surfaces in whatever colour you choose. The furniture is drawn as simple shapes based on its type and measurements, not as copies of your own pieces.

There's a point in that worth carrying with you: a model that contains no images can't reveal the contents of your home. Share the model with a buyer, and you share the house's geometry — not your belongings, your books, your family photos, or the laundry basket that happened to be out.

Photographs: only the ones you take yourself

HouseSense can save photos for a room, but that's an action you take deliberately: you take a picture and attach it to the room, typically to document something you want to remember. Those photos sit as ordinary image files in the app's own area and sync to your own private iCloud along with the rest of the home.

If you haven't taken any photos, none exist. There is no hidden layer of stills saved from the scan itself.

That also matters when sharing: the copy a buyer receives via a share code contains the home's drawings and figures — but not your photos and not your notes. Those two things deliberately don't leave the house.

What can actually be read from a scan

Fairness cuts both ways, so here is what a saved scan can tell someone who looks at it:

• The home's layout: the shape of the rooms, how they connect, and where doors and windows sit.
• The measurements: room widths, ceiling heights, window sizes, areas.
• The type of furniture that was out, and where it stood — as boxes and shapes, not as pictures. That a bed stood in a room can be read from it. What the bed looks like cannot.
• Room names and notes you've written yourself, if they're included in what you share.

The layout, with the windows' positions, is the piece of information worth thinking through before a scan leaves the house. That's not dramatic for a home already for sale with a floor plan in the listing. It's a different matter for a home that isn't publicly advertised.

Where the scan lives once it's done

In HouseSense, the scan stays in two places: locally on the device, and in your own private iCloud under your own Apple ID. There is no account and no server run by the app maker, so the scan is never uploaded to any service, and no one can look it up. That also applies to the photos you've taken yourself — they share the same fate as the rest of the home.

Want a scan gone entirely? Delete the home inside the app. That removes both the local copy and the record in your private iCloud.

The alternative, where the camera isn't involved at all

If you don't want a camera involved at all, the home can be drawn instead of scanned. HouseSense can let you draw the home on graph paper with your finger: walls are set to measurements, doors and windows are placed, and you get the same areas, the same takeoff and the same 3D model as from a scan.

That's the obvious route in situations where raising the phone would feel wrong: an apartment you rent, a room in someone else's home, or a home where someone doesn't want to be filmed. You measure with a tape measure and draw it in afterwards — the result on paper is the same.

In short

A LiDAR scan in HouseSense uses the camera along the way, but saves a description of the room — walls, openings and furniture types with measurements — not video or images. Photos exist only if you take them yourself, and they don't come along when you share the home with a buyer. The scan lives on your device and in your own private iCloud, and can be deleted entirely from inside the app.
