About Cart Health Guardian
Know what is in your cart before you buy it. Cart Health Guardian puts a 0 to 100 health score on every grocery product page, so the sugar load, the additive stack, and the processing level are visible at a glance.
WHAT IT DOES
- Scores products on Amazon, Walmart, Target, and Instacart from 0 to 100, right on the page
- Shows the top reason behind every score, with every input cited
- Weighs sugar, sodium, processing level, additives, protein, and fiber, computed on your device
- Says "not enough data" when Open Food Facts cannot back a score, and never guesses
- Keeps everything on your device except the product lookup you approve
FREE AND PRO
Free scores every product you open, ten scans a day, forever. Pro adds unlimited scans, healthier swaps, the full cited breakdown, diet rules, allergen guarding, and a monthly report, and unlocks with a Zovo membership.
BUILT HONESTLY
Cart Health Guardian is built by one independent developer. The only lookup that leaves your browser is the product name, brand, or barcode, sent to Open Food Facts with your permission. Nothing else is collected, synced, or sold.
Data: Open Food Facts (ODbL), a nonprofit open database.
PRIVACY
Everything is computed on your device. The single network request the extension makes is the product lookup you approve, sent to Open Food Facts. No browsing history, no personal data, nothing collected or sold. Full details in the privacy policy at https://zovo.one/privacy-policy.
Every plan is backed by a 14-day money-back guarantee. See plans at https://zovo.one/pricing
