Back up and restore settings

What should you keep?

Item	Purpose	Does not replace
Settings profile	Save a group of settings and apply selected items	An external backup
File backup	Store settings on a phone or PC	Full OS, driving-log or source-code recovery
QR backup	Transfer supported settings	A clone of every internal state
Branch and commit notes	Identify the affected version	The setting values themselves

Before updating

1. Park and open Carrot Web.
2. Record vehicle, device, branch and commit under Tools → Info.
3. Save a profile named with the date and vehicle.
4. Download a file backup under Tools → Settings.
5. Check that the file was actually saved on your phone or PC.

Example filename: 2026-10-30_vehicle_carrot-wip_10bf0a56.json.

Restore

1. Check that the backup matches the vehicle and branch.
2. Back up the current values first.
3. Compare the backup and current values in the restore preview.
4. Select the required items; review invalid, excluded or failed items.
5. Follow restart prompts and verify the resulting state.

The Defaults button does not restore your previous personal values. Catalogue defaults can differ from initial Params values, and updates may preserve stored settings.

Items that do not transfer

DriverMonitoringEnabled is not transferred by file, QR or profile. Restore does not import another device's disabled-DM choice or change the current device's choice. Check driver monitoring after restoring.

Do not apply another vehicle's complete settings as a recommended preset. Units, allowed ranges and vehicle applicability can differ even for the same key.
