Editorial Policy

CleanKeto is committed to providing accurate, transparent, and evidence-based nutritional guidance. Every score, recommendation, and AI-generated response is designed to inform, never to replace professional medical advice. We believe you deserve to know exactly how your food is evaluated and why.

• PQ Score methodology: Our Purity Quality scoring algorithm is developed and maintained by our team, informed by peer-reviewed research on food processing, ingredient safety, and dietary quality. Every penalty category (seed oils, added sugars, artificial additives, ultra-processing markers) is documented with its rationale.
• AI-generated coaching: Coach responses are generated by large language models (Gemini) with structured prompts that enforce evidence-based nutritional principles. AI output is constrained by system-level guardrails that prevent medical claims, discourage extreme restrictions, and flag when professional consultation is appropriate.
• For You personalization: Health-context scoring (conditions, allergens, dietary preferences) is built on documented nutritional research and conservative flagging rules. When in doubt, we flag rather than ignore.
• Nutritional data: Food composition data is sourced from USDA FoodData Central, FatSecret, and Open Food Facts. See our sourcing policy for details.

• Score breakdowns: Every PQ Score shows exactly which ingredient categories caused deductions. No black boxes.
• Confidence indicators: When data is incomplete (e.g., a food search without a full ingredient list), we indicate lower confidence rather than guessing.
• No paid placements: Food scores are never influenced by brand partnerships, advertising, or sponsorships. We do not accept payment to alter scores or recommendations.
• Corrections: If you believe a score or recommendation is inaccurate, you can report it through the app. We review and update scoring rules when evidence warrants it.

CleanKeto is a nutritional information tool, not a medical device. We do not diagnose, treat, or prescribe. Our ingredient and nutrition scores are informational only; they are not a substitute for professional dietary or clinical guidance. Always consult qualified healthcare professionals for medical decisions.

Our scoring methodology undergoes periodic review. Major changes to penalty weights, ingredient classifications, or AI coaching guidelines are tested against adversarial evaluation suites before deployment. We maintain version history for all scoring changes.
