Terms of Use

MCAS & Histamine Recipes

Last updated: August 24, 2026

Please read these Terms of Use carefully before using the MCAS & Histamine Recipes app.

These Terms of Use ("Terms") govern your access to and use of the MCAS & Histamine Recipes mobile application (the "App") provided by Lion, LLC ("Lion," "we," "us," or "our"). By using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. About the App

MCAS & Histamine Recipes is a recipe app for people managing histamine intolerance. It contains the recipe library published at histaminetracker.com, which you can browse, search, and filter by dietary need (for example dairy-free, gluten-free, egg-free, nut-free, vegan, or low-FODMAP, and recipes without common histamine liberators or DAO blockers). Each ingredient links to its general histamine rating from the histaminetracker.com food index, and the App includes favorites, a grocery list, and offline access. Browsing the full library, search, filters, favorites, the grocery list, and a selection of open recipes in every category are free and do not require an account or login. The remaining recipes are unlocked by a paid upgrade: an auto-renewable subscription or a one-time lifetime purchase (see Section 6, "Subscriptions and Purchases"). It is designed as an educational tool.

2. Eligibility

The App is intended for users aged 18 and older. By using the App, you represent that you are at least 18 years old.

3. License

Lion grants you a limited, non-exclusive, non-transferable, revocable license to use the App strictly in accordance with these Terms.

4. Medical and Nutritional Disclaimer

The App is provided solely for educational and informational purposes. It does not provide medical advice, diagnosis, treatment, nutritional counseling, or professional healthcare services.

You acknowledge and agree that:

• Recipes in the App are educational content, not medical or dietary advice, and are not tailored to your individual condition
• Ingredient ratings are general information. Food histamine levels can vary based on freshness, preparation, storage, and individual sensitivity
• Individual tolerance varies. A recipe or ingredient described as low histamine, or shown under a dietary filter, may still not be suitable for you
• The information in the App should not be relied upon for medical or health-related decisions
• You should always consult a qualified healthcare professional regarding dietary changes, medical conditions, or symptoms
• The App does not create a doctor-patient or other professional relationship between you and Lion, LLC

Dietary filters and labels in the App (such as "Dairy-free" or "No DAO blockers") are derived automatically from each recipe's ingredient list and are provided as a convenience. They can be incomplete, inaccurate, or incorrect, and they do not account for cross-contamination, substitutions, optional ingredients, or the specific products you use. Always check a recipe's ingredients and the labels of the products you buy, and verify with a qualified professional if you have an allergy or a medical dietary restriction.

5. Health and App Store Compliance

The App is a general wellness and educational tool only. It is not a medical device and is not regulated, cleared, or approved by the U.S. Food and Drug Administration (FDA) or any other regulatory authority.

The App:

• Does not provide medical advice, diagnosis, or treatment
• Does not claim to prevent, cure, or treat any disease or medical condition
• Does not replace professional medical consultation

If you believe you may have a medical condition or are experiencing a health emergency, contact a qualified healthcare professional or emergency services immediately.

6. Subscriptions and Purchases

Most recipes in the App require an optional paid upgrade: an auto-renewable subscription or a one-time lifetime purchase. Browsing the library, search, filters, favorites, the grocery list, and the open recipes in every category remain free and do not require a purchase.

• Plans and price: The upgrade is offered as an annual subscription or a one-time lifetime purchase, at the prices shown in the App (pricing may vary by region and is confirmed at the time of purchase). Payment is charged to your Apple ID account upon confirmation of purchase.
• Free trial: Subscription plans may include a free trial. Trial eligibility is determined by Apple and generally applies to first-time subscribers. If you do not cancel at least 24 hours before the free trial ends, the subscription automatically converts to a paid subscription at the applicable rate. If you are not eligible for a trial, payment is charged upon confirmation of purchase. The lifetime purchase does not include a trial.
• Auto-renewal: Subscriptions renew automatically for the same period unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period. The lifetime purchase is a single payment and does not renew.
• Managing your subscription: You can view, manage, or cancel your subscription, and turn off auto-renewal, in your device's App Store account settings after purchase.
• Restoring purchases: If you reinstall the App or use another device with the same Apple ID, you can restore an active subscription or lifetime purchase from within the App.
• Refunds: Purchases are processed by Apple and are subject to Apple's refund policies. Except where required by law, fees already paid are non-refundable.

Apple's standard Licensed Application End User License Agreement, available at apple.com/legal/internet-services/itunes/dev/stdeula/, also applies to your use of the App to the extent it does not conflict with these Terms.
