Purple Magnesium: user data policy - other requirements

What the policy actually says

Other Requirements: The following types of personal or sensitive user data are also subject to additional requirements: Financial or Payment Information - Don't publicly disclose financial or payment information. Authentication Information - Don't publicly disclose authentication information. Web Browsing Activity - Collection and use of web browsing activity is prohibited except to the extent required for a user-facing feature described prominently in the Product's Chrome Web Store page and in the Product's user interface.

Program policy and Google's troubleshooting entry

What Google lists as triggering it

• The extension is collecting Web Browsing Activity when it is not needed for a user facing feature.
• Sensitive user information collected using the extension is being disclosed publicly.

What Google says to do about it

• Don't collect Web Browsing Activity unless it is required for a user-facing feature.
• Ensure user information is not being disclosed publicly

This one changed, and is enforced from 2026-08-01

Google's wording, quoted rather than summarised: "Enforcement for these updated policies will begin on August 1, 2026. Extensions found out of compliance after this date may face enforcement action from the Chrome Web Store."

Check your own package for this

The same verified data drives a free command line checker. It reads an unpacked extension and reports what would be flagged, citing the notification ID and Google's verbatim text. No dependencies, nothing leaves your machine, MIT licensed.

git clone https://github.com/Circadian-agent/webstore-lint
node webstore-lint/bin/webstore-lint.mjs ./my-extension

A clean run is not a promise of approval. The checker reads your package; it cannot see your store listing, your privacy policy page or your screenshots, and several policies are satisfied in exactly those places.

If you have already been rejected

The resubmission pack is written work, produced against your actual package after you buy it: a justification for every permission you request pointing at the lines that need it, the narrower permission where one exists, and a single purpose statement that matches what your code does. It is 149 USD, once.

It does not buy an approval, because we do not review extensions and cannot promise what Google decides. It buys the writing that the dashboard asks you for and that a rejection means you now have to get right.

The other 35

All 36notification IDs, with the four 2026 policy changes and the places Google's own pages contradict each other, are on the full reference. The dataset behind it is CC BY 4.0.
