Privacy Policy

LabelJet — Chrome extension by Projectus B.V. · Last updated: 21 July 2026

This privacy policy describes how the LabelJet browser extension ("LabelJet", "the extension") handles data. LabelJet is designed to work locally: processing happens in your own browser.

What data do we collect?

None. LabelJet collects, sells or shares no personal data and sends no data to the developer or to external servers. There is no tracking, analytics or advertising code.

How are your labels processed?

  • When you print a shipping label, LabelJet fetches the corresponding PDF using your own existing session with your shipping tool and processes it entirely locally in your browser (rendering a preview and converting it to a printable image).
  • The label content (such as names and addresses) stays on your device and is only sent to the USB printer you choose.
  • None of this content is transmitted to the developer or third parties, or stored off your device.

Local storage

LabelJet stores your settings (such as printer USB id, label size, density, rotation and threshold) locally via chrome.storage. A captured label is placed temporarily in chrome.storage.session to hand it to the print window and is cleared when the session ends. This data does not leave your device.

Permissions used

  • storage — save settings and pass a label to the print window.
  • downloads — detect when a label PDF is downloaded, so it can be printed.
  • printerProvider — (ChromeOS only) offer the printer in the print dialog.
  • Access to shipping pages — recognize the label flow and fetch the PDF.
  • WebUSB — after your explicit choice, send the label to the USB printer.

Third-party services

LabelJet communicates only with the shipping tool you use yourself (to fetch your own label). No other external services are contacted.

Disclaimer

LabelJet is provided "as is", without any warranty. Use is at your own risk; Projectus B.V. accepts no liability for its operation or for any damage arising from its use. Always check printed labels yourself before shipping.

Not affiliated

LabelJet is independent and not affiliated with, made by, or endorsed by MyParcel, PostNL or Shopify. Those names are the property of their respective owners and are used only to describe compatibility.
