Terms of Use

Histamine Tracker

Last updated: August 1, 2026

Please read these Terms of Use carefully before accessing or using the Histamine Tracker service.

These Terms of Use ("Terms") govern your access to and use of the Histamine Tracker mobile application and related services (collectively, the "Service") provided by Lion, LLC ("Lion," "we," "us," or "our"). By accessing or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. Eligibility

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

2. License

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

3. Medical, Nutritional, and AI-Generated Content Disclaimer

3.1 Educational and Informational Use Only

The Service is provided solely for educational, informational, and self-tracking purposes. It does not provide medical advice, diagnosis, treatment, nutritional counseling, or professional healthcare services. The Service is not intended to replace consultation with a licensed physician, dietitian, pharmacist, or other qualified healthcare professional.

You acknowledge and agree that any information provided through the Service should not be relied upon for making medical or health-related decisions. Always seek the advice of a qualified healthcare provider regarding any medical condition, symptoms, medications, supplements, or dietary changes.

3.2 AI-Generated Insights Disclaimer

The Service may generate insights, summaries, correlations, or feedback using artificial intelligence ("AI"), including but not limited to analysis related to foods, supplements, symptoms, activities, or patterns, and identification of foods, ingredients, or products from photos or barcodes you scan ("Scan Food"). AI features are powered by third-party services (currently Anthropic and OpenAI), which process your entry data, including scanned photos and the text derived from them, to generate insights. AI can misread labels, misidentify foods, and produce incomplete or incorrect results, and product formulations change over time, so always check the actual product label before relying on a scan. See our Privacy Policy for details on how your data is handled.

AI-generated outputs:

You agree that any reliance on AI-generated content is entirely at your own risk. Lion, LLC makes no representations or warranties regarding the accuracy, completeness, or suitability of AI-generated outputs.

3.3 Supplements, Pills, and Food Guidance

Any references to supplements, pills, foods, ingredients, or dietary patterns are provided for general educational awareness only. The Service does not recommend starting, stopping, or modifying any supplement, medication, or diet.

Consult a qualified healthcare professional before making any changes involving medications, supplements, or dietary intake.

3.4 No Doctor–Patient Relationship

Your use of the Service does not create a doctor-patient, clinician-patient, or other professional relationship between you and Lion, LLC.

3.5 Community Content Is Not Medical Advice

The Service includes a community where users can share posts, comments, photos, and snapshots of their tracking data with each other. Community content is provided by other users for peer-support and informational purposes only. It reflects personal experiences and opinions, not medical advice, diagnosis, or treatment. We do not verify community content for medical accuracy, safety, or effectiveness, and community members are generally not medical professionals. Never disregard professional medical advice, or delay seeking it, because of something you read in the community.

Participation in the community does not create a doctor-patient or other clinical relationship between you and Lion, or between you and any other user. If you believe you may be experiencing a medical emergency, contact your local emergency services immediately.

4. Apple App Store and Google Play Health Compliance

The Service is a general wellness, education, and self-tracking 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 Service:

Any health-related information, insights, correlations, summaries, or AI-generated feedback provided through the Service are intended solely for general wellness and educational purposes and are not intended for medical decision-making.

You acknowledge and agree that:

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

Lion, LLC expressly disclaims any liability arising from your use of the Service in a manner inconsistent with these disclosures or applicable platform guidelines.

5. Intellectual Property

All content, features, functionality, trademarks, and intellectual property related to the Service are owned by Lion, LLC or its licensors and are protected by copyright, trademark, and other intellectual property laws. You may not copy, modify, distribute, sell, or lease any part of the Service without prior written consent.

6. User Content and Community

6.1 Your Content and License to Us

The Service allows you to submit content, including private tracking entries and the posts, comments, reactions, photos, profile information, and attached data cards you choose to share in the community (collectively, "User Content"). You retain ownership of your User Content. You are solely responsible for it, and you represent that you have all rights necessary to submit it and that it does not violate these Terms or any law.

By submitting User Content, you grant Lion a non-exclusive, worldwide, royalty-free license (sublicensable solely to service providers operating on Lion's behalf) to host, store, use, reproduce, process, analyze, display, and distribute that content solely to operate, maintain, and improve the Service, including displaying content you share in the community to other users. We will not display your private tracking entries to other users unless you choose to post them. This license ends when you delete the relevant content or your account, except that (a) deleted content may persist for a limited time in routine backups, and (b) we may retain content as reasonably necessary to comply with legal obligations, resolve disputes, enforce these Terms, or investigate violations.

6.2 Community Rules

The community is a peer-support space. The app requires you to review and agree to these rules and these Terms before your first post or comment. By posting or commenting, you agree to follow these rules:

We have zero tolerance for objectionable content or abusive behavior in the community.

6.3 Public Visibility

Anything you post in the community, including photos and any health-related information, is visible to other users of the Service. Do not post anything you are not comfortable making visible to others. See our Privacy Policy for details on how community information is handled.

6.4 Moderation and Enforcement

We have no obligation to pre-screen, monitor, or edit User Content, but we reserve the right to do so, including through automated filtering, and content that other users report may be temporarily hidden while we review it. We may remove, hide, restrict, or decline to publish any User Content, and may warn, suspend, ban, or terminate any user, at any time, at our sole discretion, with or without notice, including for conduct that violates these Terms or the community rules. A community ban restricts your ability to post, comment, or react in the community; a banned user can still use the rest of the Service and read the community. Separately, and independent of any community ban, we may suspend or terminate your access to the Service entirely for serious or repeated violations, for security or legal reasons, or for any other lawful reason.

The Service provides in-app tools to report content and to block other users (blocking a user hides their posts and comments from you), and you can also contact us at [email protected]. We review reports promptly and take the action we consider appropriate, including removing content and suspending or banning the responsible user.

6.5 Interactions with Other Users

You are solely responsible for your interactions with other users. We do not verify any user's identity, background, or qualifications. To the fullest extent permitted by law, you release Lion from any claims, damages, or disputes arising out of or relating to your interactions with other users or to content posted by other users.

6.6 No Endorsement

User Content reflects the views of the user who posted it, not the views of Lion. We do not endorse, verify, or guarantee the accuracy, completeness, or usefulness of any User Content, and we are not responsible or liable for it. Any reliance you place on User Content is at your own risk.

6.7 Copyright Complaints

We respect intellectual property rights. If you believe content in the community infringes your copyright, send a notice to [email protected] that includes: (a) identification of the copyrighted work; (b) identification and location of the allegedly infringing material; (c) your contact information; (d) a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; (e) a statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act on the owner's behalf; and (f) your physical or electronic signature. Lion's designated copyright agent is registered with the U.S. Copyright Office as "Copyright Agent, Lion, LLC" and can be reached at the email above. We will remove or disable access to infringing content and may suspend or terminate the accounts of repeat infringers.

6.8 Feedback

If you send us feedback, ideas, or suggestions, you agree that we may use them without restriction and without obligation or compensation to you.

7. Third-Party Services and Links

The Service may integrate with or link to third-party services. Lion does not control and is not responsible for third-party content, functionality, availability, or practices. Your use of third-party services is governed by their respective terms.

These Terms are between you and Lion only, not with Apple Inc. or Google LLC. Apple and Google are not responsible for the Service or its content and have no obligation to provide maintenance or support for it. To the extent required by an app store's terms, Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

8. Subscriptions, Purchases, and Billing

Certain features of the Service require a paid upgrade: a subscription or, where offered, a one-time lifetime purchase. Prices are shown in the app at the time of purchase and may vary by region. Subscription plans may offer a free trial period. If you do not cancel before the free trial ends, your subscription will automatically convert to a paid subscription at the applicable rate. A one-time purchase is a single payment, does not include a trial, and does not renew.

All purchases, subscriptions, renewals, cancellations, and refunds are handled through third-party platforms such as the Apple App Store and Google Play and are subject to their respective terms and policies.

Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period. You can manage and cancel subscriptions through your device's app store settings. Deleting your account does not automatically cancel a subscription; cancel it through your device's app store.

9. Termination

Lion reserves the right to suspend or terminate your access to the Service or any part of it (including the community), and to remove any User Content, at any time, with or without notice, for any violation of these Terms or for any other lawful reason. Provisions that by their nature should survive termination (including Sections 3, 5, 10 through 14, and the license-retention exceptions in Section 6.1) will survive.

10. Disclaimer of Warranties

The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied. Lion expressly disclaims all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, accuracy, reliability, and non-infringement.

11. Limitation of Liability

To the fullest extent permitted by law, Lion, LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, data, health outcomes, or goodwill, arising out of or related to your use of the Service or reliance on any content provided.

In no event shall Lion's total liability exceed the greater of (a) the amounts paid by you to Lion in the twelve (12) months prior to the claim, or (b) one hundred dollars ($100 USD).

12. Indemnification

You agree to indemnify, defend, and hold harmless Lion, LLC and its officers, members, employees, and agents from any claims, damages, losses, liabilities, or expenses (including attorneys' fees) arising from your use of the Service, your User Content, or your violation of these Terms.

13. Dispute Resolution

Any dispute arising from these Terms shall be resolved through binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules. You agree to waive any right to participate in a class action lawsuit or class-wide arbitration.

You may opt out of this arbitration agreement by sending written notice to [email protected] within 30 days of first accepting these Terms.

14. Governing Law and Venue

These Terms shall be governed by and construed in accordance with the laws of the State of Illinois, without regard to its conflict-of-law principles. For any disputes not subject to arbitration, you agree to the exclusive jurisdiction of the state or federal courts located within the State of Illinois. If you are a consumer in a jurisdiction whose laws grant you mandatory consumer rights, or the right to bring claims in your local courts, nothing in these Terms limits those rights.

15. Severability

If any provision of these Terms is found invalid or unenforceable, the remaining provisions shall continue in full force and effect.

16. Force Majeure

Lion shall not be liable for any failure or delay in performance due to circumstances beyond its reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, labor disputes, power outages, internet failures, or government actions.

17. Assignment

You may not assign or transfer these Terms or your rights under them without Lion's prior written consent. Lion may assign its rights and obligations under these Terms without restriction.

18. Entire Agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and Lion regarding the Service and supersede all prior agreements, representations, and understandings.

19. Changes to These Terms

Lion reserves the right to modify these Terms at any time. Material changes will be communicated through the Service. Continued use of the Service after changes constitutes acceptance of the updated Terms.
