Privacy Policy — UPC Generator

Last updated: 2026-06-18

UPC Generator is a Chromium browser extension that renders UPC-A, UPC-E, FNSKU, and Code128 barcodes by calling the project’s HTTPS backend API.

Data the extension sends to the server

When you click “Generate”, the extension sends:

• the symbol type (e.g. UPCA);
• the input string you typed (the barcode data);
• an anonymous request ID to correlate logs.

The server uses these values only to render the barcode image. We do not collect names, emails, browsing history, cookies, IP geolocation data, or any data unrelated to barcode rendering.

Data the extension stores locally

The extension stores in chrome.storage (on your device only):

• your UI preferences (selected symbol, appearance options);
• a local history of recently generated barcodes (metadata only — symbol + data — no images).

This data never leaves your device unless you explicitly trigger a new “Generate” action, in which case only the symbol + data are sent.

Transit and storage

All API calls use HTTPS (TLS 1.2+). Request logs on the server are retained for 30 days for abuse prevention and are then deleted.

Third parties

We do not share any data with third parties, advertisers, or analytics providers. There are no trackers in the extension.

Permissions justification

• storage — saving UI preferences and local history on your device.
• clipboardWrite — the “Copy barcode” button.
• downloads — exporting the barcode as SVG or PNG.
• host permission — the single HTTPS endpoint used to render the barcode image. No other network calls are made.
