# GRID Navigator Support

> Help, requirements, and contact for the GRID Navigator iOS app

GRID Navigator is the iOS capture app for the GRID platform. It records
synchronized color video, LiDAR depth, and device motion in a single walk-through
— the raw data used to build the maps and datasets robots navigate with.

## Get help

Email [gridnav@generalrobotics.company](mailto:gridnav@generalrobotics.company).
We aim to respond within two business days. Include your device model, iOS
version, and the app version from the profile screen.

## Requirements

* An iPhone with a LiDAR sensor (iPhone Pro models) for depth capture
* iOS 15.6 or later
* Camera and Motion permissions — both are required to record, and you can
  change them any time in **Settings → GRID Navigator**

## Getting started

**Try it without an account.** Tap **Continue in Demo Mode** on the login
screen. Capture runs entirely on your device; nothing is uploaded.

**Sign in to your organization.** Tap **Add GRID server** and enter the server
your GRID administrator gave you, then sign in. Accounts are provisioned by your
organization — there is no public sign-up.

## Troubleshooting

**Recording won't start**

* Confirm Camera and Motion access are allowed in **Settings → GRID Navigator**.
* Depth capture needs a LiDAR-capable device; non-LiDAR iPhones can't record
  depth.

**Scans look incomplete or drift**

* Move slowly and keep surfaces in view; fast turns lose tracking.
* Featureless walls and glass give the tracker little to lock onto — include
  more of the room.

**Upload is unavailable**

* Uploading requires signing in to a GRID server. In Demo Mode it stays
  disabled by design, and captures remain on your device.
* If you are signed in and uploads still fail, check that your device can reach
  your organization's GRID server, then contact support.

**Running out of space**

* Captures are written to the device. Delete sessions you've already uploaded
  from the session list to reclaim space.

## Accounts and data

Accounts are provisioned by your organization, so there is no in-app sign-up or
deletion. To request access to — or deletion of — your account and its captured
data, contact your organization administrator or email
[gridnav@generalrobotics.company](mailto:gridnav@generalrobotics.company).

What the app collects and how it's handled is described in the
[General Robotics Privacy Policy](https://www.generalrobotics.company/privacy-policy).
