Updated: Sep 5, 2026

Account-Free, Privacy-First Health Tools

Instant Access Without Sign-Up

OneBody Project is designed from the ground up with a privacy-first philosophy. We believe you should not have to provide personal contact details, create passwords, or surrender your email just to know what is inside your food:

  1. Zero Registration: Use the Ingredients Decoder, photo label scanner, and all health calculators instantly.
  2. Device-Level Storage: Any preferences you configure are retained directly on your current device.
  3. No Hidden Tracking: We do not build personal marketing profiles based on the foods you analyze.

Customizing Analysis Preferences

To tailor the Ingredients Decoder to your specific health goals and dietary needs:

  1. Navigate to the Ingredients Decoder.
  2. Scroll to the Analysis Preferences section right below the input area.
  3. Select your lifestyle options:
    • Dietary Profiles: Gluten-Free, Dairy-Free, Vegan, Vegetarian, Keto, Low-FODMAP.
    • Harmful Additives Alerts: Automatically flag artificial dyes, high-fructose corn syrup, nitrates, and controversial preservatives.
    • Allergen Warnings: Set alerts for nuts, soy, eggs, shellfish, and artificial sweeteners.

Keeping Your Preferences Up to Date

Whenever you adjust an ingredient preference or dietary rule on the Decoder page, your choices update in real time. The next time you paste ingredients or snap a label photo, your customized rules will be applied automatically.

Clearing Local Data

If you ever want to reset your preferences or clear your stored scans, you can do so in one click from the Saved Scans page or by clearing your browser’s site data.
