Transparent scoring
JFS shows supporting nutrition and ingredient information so a score is not presented as a mysterious verdict. Read how scoring works.
Trust center
Built to explain, not just judge.
The important details — scoring, sources, privacy, limits, support, and deletion — should be easy to inspect before you rely on JFS.
Named data sources
USDA FoodData Central and Open Food Facts can provide product information. Optional user-requested photo analysis is processed through the JFS server-side AI workflow. See data-source details.
Clear limitations
JFS is a general educational tool. Product databases and package information can be incomplete or outdated, and the app is not medical, dietary, or allergen-safety advice.
Privacy choices
Core guest features can work without an account. Users can decline photo upload, avoid cloud backup, clear local data, or delete a cloud account. Read the privacy policy.
Support and account controls
Support, account deletion, subscription-management guidance, and legal information are publicly accessible from this website.
