Woolies Protein Tags — Privacy Policy

Last updated: 26 May 2026

Woolies Protein Tags (the “extension”) is a Chrome browser extension that displays a protein-density rating on every product tile at woolworths.com.au.

What data we collect

None that leaves your browser.

The extension reads product nutrition information from the woolworths.com.au API responses your browser already receives while you shop. It extracts only two values per product — protein (grams) and energy (kilojoules) — and stores them locally in Chrome’s built-in chrome.storage so the rating appears instantly on subsequent visits.

What we don’t do

We do not collect, transmit, sell, or share any personal information, browsing history, account details, search queries, cart contents, or any other data. The extension makes no network requests to servers operated by us or any third party. All processing happens locally inside your browser.

The extension does not modify your Woolworths account, shopping cart, delivery address, or any other Woolworths-side state.

Permissions

storage – used solely to cache per-product nutrition values locally, so badges appear instantly when you revisit a page.

Host access to https://www.woolworths.com.au/* – the extension runs only on Woolworths pages so it can read the nutrition information already on the page and inject the rating pill.

Removing the extension

Uninstalling the extension via chrome://extensions automatically deletes all locally cached nutrition data. No traces remain on your machine or anywhere else.
