# Standalone Trackers

> Understand device registration, session settings, and sharing controls for standalone shipment tracking.

A standalone tracking session lets you review device tracking without a Chrt order. The **Devices** page holds device records, and **Sessions** holds the sessions associated with devices.

> **Note**
>
> This guide explains the available controls. Confirm device compatibility and the physical setup for your shipment with [trackers@chrt.com](mailto:trackers@chrt.com) before starting. Registration and shipment setup instructions depend on that validation.

## Device records

Open [Devices](https://chrt.com/tracking/devices) to review the devices available to your organization. **Register Device** opens a form with **Device MAC Address** 1, an optional **Device Type** 2, **Comments** 3, and **External Reference ID** 4. The form's own **Register Device** button 5 is disabled while the form is blank. Use the identifier for the actual device; the type label alone does not establish the hardware's capabilities.

*The **Register Device** dialog on the **Devices** page, blank. **1** **Device MAC Address** (required); under **Optional Information**, **2** **Device Type**, **3** **Comments**, **4** **External Reference ID**, **5** **Register Device**, disabled while the form is blank.*

After registration, check the saved device record and its identifier. Registration and a location reading are separate checks: a saved record does not establish that the hardware is reporting.

## Session settings

On [Sessions](https://chrt.com/tracking/sessions), **Create Session** opens **Create Tracking Session**. The form offers selection of a registered device or entry of a device identifier, with optional reference, comments, flight information, contacts, and termination settings.

Sessions are set to terminate after **7 days by default**. The form allows a different termination date and time or **No auto termination**. Review the termination setting for the shipment rather than assuming that the default matches its duration. Longer or open-ended sessions may incur **additional tracking charges** depending on your subscription.

A tracking session records location and metadata from a registered device for as long as the session is active (subject to your termination settings and subscription).

## Review a session

Open the session you intend to follow. **Session details** includes timestamps such as **Created** 1, **Last seen** 2, and **Terminated** when present, plus reference, comments, flights, and **Scheduled termination** for an unterminated session. Compare the device identifier and last-seen time with the shipment you are following.

*Part of **Session details**, with each timestamp followed by a time-zone label (PDT and GMT+3 here). **1** **Created** time, **2** **Last seen** time.*

Lower in **Session details**, **Comments** 1 holds notes for the session, **Add Flight** 2 adds a flight (it is disabled once a session is terminated), and **Loaded status** 3 shows the loaded state.

*Part of **Session details** for a terminated session. **Add Flight** is disabled with the note that terminated sessions are ineligible for flights. **1** **Comments**, **2** **Add Flight**, **3** **Loaded status**.*

The recording control can show **REC**, **Paused**, or **Terminated** 1. Where your access permits, it offers **Pause** or **Resume**, and a separate **Terminate** action. Read the confirmation before ending a session. Check the saved status afterward; these controls do not establish how much historical data is retained.

*The session's recording control, showing **Terminated** once the session has ended. **1** **Terminated** state.*

If a session has no recent data, record the device identifier, session identifier, and last-seen time when asking [trackers@chrt.com](mailto:trackers@chrt.com) for help. This guide does not set a first-report or update-time guarantee.

## Making a session public

In **Session details**, the **Public tracking** section has **Share**. The **Session public tracking sharing** 1 dropdown can be set on or off when your access permits. The panel offers copy and open-link controls while public sharing is enabled; with sharing set to **Off**, the **Copy link** 2 button is disabled.

![The public sharing panel, numbered 1 and 2: the Sharing is dropdown set to Off, and the disabled Copy link button](/_fern-files/_img/9e78f35e513efee963531179522f2d02c2afde7205fb7768ef0a585332032964.webp)

*The public sharing panel opened from **Share** under **Public tracking**. **1** **Session public tracking sharing** dropdown (shown as **Sharing is**, set to **Off**), **2** **Copy link** button (disabled).*

After a sharing change, reload the settings and check the displayed state. Test the intended recipient's view before distributing a link. Changing this setting is not a guarantee about previously viewed or copied data. See [Sharing](/dev/trackers/sharing) for organization sharing and the boundaries of public links.
