Device management

Every computer where you sign in to the DroneField desktop application is automatically registered to your account as a device. The list and controls are on the portal’s Devices page.

What’s it for?

• Overview: which machines are currently signed in.
• Security: if you lose or replace a machine, you can revoke access — no further processing can start from there.
• Troubleshooting: see when the machine last reported in, which version it runs, what hardware it has.

How a device registers

The desktop application sends a registration packet at first sign-in:

• A random UUID (device identifier)
• The machine name (e.g. “MacBook Pro M3”)
• The platform (windows / macos / linux)
• A hardware fingerprint — a hash of hardware components; this identifies the device without transmitting sensitive data
• Basic CPU / RAM / GPU info (for diagnostics)

After registration the app sends a heartbeat every 15 minutes so the server knows the device is online.

The Devices page

Each device is shown on a card with:

• Device name (currently set automatically from the OS)
• Platform icon (Windows / macOS / Linux)
• Status badge:
  • Active (green) — alive, recent heartbeat
  • Inactive (grey) — hasn’t reported in more than 24 hours
  • Revoked (red) — manually revoked
  • Suspended (yellow) — held for security reasons
• Hardware (CPU, RAM, GPU)
• Last heartbeat time
• Application version last seen on this machine
• Revoke button (only on active devices)

Revoking a device

If you lose or sell a computer, revoke it from your account:

1. On the Devices page click Revoke on the relevant device card.
2. The confirmation dialog appears — click OK.
3. The revocation takes effect immediately: at its next heartbeat (within 15 minutes) the desktop app signs out automatically.
4. Any in-flight processing stops, and the device status becomes Revoked.
5. You receive a confirmation email for security.

How many devices can I have?

DroneField does not enforce a hard limit, but only one device can run processing at a time (the default licence seat is 1).

If you need multiple parallel seats, get in touch — we offer custom multi-seat plans.

Unknown device on the list?

If you see an unfamiliar device under Active, do this immediately:

1. Revoke the device as above.
2. Change your password (see Sign in & password management).
3. Notify us via the portal support form — we’ll help review the account activity.

Revoked or expired devices

Revoked and Inactive devices stay on the list — so you can see the account history. If they get in the way, contact us; we can remove them manually.
