Your files stay in your browser.
Commerce Guardian reads CSV files in the tab’s memory. Your catalog, Merchant Center report and product values are never uploaded or stored on a server.
What is measured
Cloudflare Web Analytics measures aggregate page views without advertising cookies. Four aggregate product events are counted: completed real scan, supplemental download after a real scan, demo start and demo completion. Each event contains only its allow-listed name and an internal/external test bucket. No cookie, CSV content, file metadata, product ID, attribute, value, result count, full URL or referrer is sent.
What remains on your device
Analysis and file generation happen locally. Refreshing or closing the tab clears the analysis. Your browser, extensions, operating system and download history remain outside the site’s control.
Good practice
Use a trusted browser and always review the supplemental feed before importing it into Merchant Center.
