Chrome Extension Privacy Policy

This policy covers the GrabPrinter Host Chrome extension specifically. Our main site-wide Privacy Policy covers everything else.

Single purpose

The extension has one job: maintain a connection to grabprinter.com, receive incoming print-job PDFs for the signed-in owner, and hand them to Chrome's print dialog so the owner can print them to their local printer.

What the extension stores

• A pair code and authentication token (JWT) for your GrabPrinter account, stored in chrome.storage.local. These let the extension reconnect to grabprinter.com without asking you to re-authenticate.
• An optional debug base URL (for internal testing). Blank by default.

Nothing else is stored locally. Tokens are cleared when you click Disconnect in the popup.

What the extension transmits

• Pair requests, token claims, and WebSocket traffic — all over HTTPS to grabprinter.com only.
• The PDF of each incoming print job, fetched from a short-lived signed URL proxied through grabprinter.com, so the extension can load it into Chrome's print dialog.
• Status updates back to grabprinter.com when a job is printed or fails.

We do not send data to any third-party servers, analytics providers, or ad networks from within the extension itself.

What the extension does not do

• Does not read your browsing history, cookies from other sites, or content of other tabs.
• Does not enumerate installed printers or read their configuration. Chrome's print dialog handles printer selection.
• Does not print silently — every job requires you to click Print in Chrome's standard dialog.
• Does not collect any personally identifiable information beyond the pair token (which is tied to your GrabPrinter account).
• Does not use or transfer user data for creditworthiness, lending, or any purpose unrelated to routing your print jobs.
• Does not sell or transfer user data to third parties.

Permissions we request

• storage — to remember the pair token between browser restarts.
• notifications — to alert you when a print job arrives.
• alarms — to keep the WebSocket connection alive across Chrome's service-worker idle timeouts.
• offscreen — to render the incoming PDF and trigger the print dialog (service workers can't call window.print() directly).
• host access to grabprinter.com and subdomains — to talk to our server. No other domains.

Data retention

PDFs for print jobs are not stored by the extension at all — they're streamed from grabprinter.com into Chrome's print dialog and the blob URL is revoked immediately after. Server-side PDFs are deleted 24 hours after the job completes or is cancelled (see main privacy policy for details).

Your choices

• Click Disconnect in the popup to clear all stored tokens and stop the WebSocket.
• Remove the extension from chrome://extensions to permanently delete all local data.
• Delete your GrabPrinter account from your dashboard to revoke all paired devices server-side.
