Effective Date: September 6, 2026
Last Updated: September 6, 2026

Khinaxio Holdings LLC (“Khinaxio Holdings,” “Khinaxio,” “we,” “us,” or “our”) respects your privacy and is committed to protecting information collected through our websites, mobile applications, products, and related services.

This Privacy Policy explains how we collect, use, disclose, retain, and protect information when you access or use the Khinaxio Holdings website, Heroes One mobile application, and other services that link to this Privacy Policy (collectively, the “Services”).

The information we collect depends on how you interact with our Services and which features you use.

This may include your:

If purchases are processed through platforms such as the Apple App Store or Google Play, payment information is generally processed by the applicable platform or payment provider.

• Subscription status;
• Product or subscription purchased;
• Purchase or renewal date;
• Transaction identifier;
• Subscription expiration status;

We do not receive or store your full credit-card number when payment is handled entirely by a third-party payment provider.

When you use our website or application, certain information may be collected automatically.

Depending on the Services and technologies implemented, this may include:

We may use this information to operate, maintain, secure, troubleshoot, and improve our Services.

4. Cookies and Similar Technologies

Cookies may include:

Essential cookies: Necessary for core website functionality and security.

Preference cookies: Used to remember certain user preferences.

Analytics cookies: Used, if enabled, to help us understand how visitors interact with our website.

The specific cookies used may change as our website and services evolve.

You may be able to control cookies through your browser settings. Disabling certain cookies may affect website functionality.

Where required by applicable law, we will request appropriate consent before using non-essential cookies or similar tracking technologies.

We may use analytics, performance-monitoring, crash-reporting, or diagnostic technologies to understand how our Services function and to identify technical problems.

Information collected through these technologies may include device information, application version, feature usage, crash reports, performance information, and other technical data.

We use this information to:

• Diagnose errors and crashes;
• Improve application stability;
• Understand feature usage;
• Improve user experience;

Where applicable, we may also use information for other purposes disclosed to you at the time it is collected.

7. Heroes One and Health Information

Heroes One is designed as a clinical reference and educational resource for healthcare professionals, emergency medical personnel, students, and other users.

Unless a specific feature expressly states otherwise, users should not enter personally identifiable patient information, protected health information (“PHI”), medical records, or other confidential patient information into Heroes One.

Clinical calculators and reference tools should be designed, where possible, to function without requiring information that directly identifies an individual patient.

For example, a clinical calculation may require information such as weight or other clinical variables to perform a calculation. Such information should not be combined with patient names, medical-record numbers, dates of birth, addresses, or other patient identifiers unless a feature expressly supports such information and appropriate privacy protections have been implemented.

Heroes One is not intended to function as an electronic health record (“EHR”) or patient medical-record system unless expressly stated otherwise.

8. HIPAA

Khinaxio Holdings does not represent that every use of Heroes One constitutes a service subject to the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”).

Whether HIPAA applies depends on, among other things, the nature of the information involved, how a service is used, and the relationship between the parties.

Unless expressly agreed otherwise in writing, users should not use the Services to transmit or store PHI requiring a HIPAA-compliant service or Business Associate Agreement.

Healthcare professionals and organizations remain responsible for complying with their own privacy, confidentiality, documentation, and information-security obligations.

9. Clinical Information and Medical Disclaimer

Heroes One may contain medical, clinical, medication, laboratory, calculation, educational, and reference information.

Heroes One does not replace:

• Professional clinical judgment;
• Patient-specific assessment;
• Institutional policies and procedures;
• Medical direction;
• Current treatment protocols;
• Medication labeling;
• Appropriate medical consultation;
• Applicable laws and regulations.

Users are responsible for independently verifying information before applying it to patient care.

Information entered into calculators should be limited to the minimum information necessary to perform the calculation and should not include patient-identifying information unless expressly permitted by the applicable feature.

10. How We Share Information

We do not sell personal information in exchange for money.

We may disclose information in limited circumstances, including to service providers that perform services on our behalf, such as:

• Website hosting;
• Cloud infrastructure;
• Application hosting;
• Authentication;
• Email delivery;
• Customer support;
• Analytics;
• Crash reporting;
• Subscription management;
• Security and fraud prevention.

These providers may process information only as permitted by their agreements with us and applicable law.

We may also disclose information when reasonably necessary to comply with law, legal process, court orders, governmental requests, protect our rights, investigate fraud or security incidents, or protect users or others.

11. Business Transfers

If Khinaxio Holdings is involved in a merger, acquisition, financing, reorganization, bankruptcy, sale of assets, or similar corporate transaction, information may be transferred as part of that transaction as permitted by applicable law.

Any successor organization may continue to process information consistent with this Privacy Policy unless otherwise required by law.

12. Data Retention

We retain personal information only for as long as reasonably necessary for the purposes for which it was collected, including to:

• Provide the Services;
• Maintain accounts;
• Complete transactions;
• Resolve disputes;
• Maintain security;
• Prevent fraud;
• Comply with legal requirements;
• Enforce agreements.

Retention periods may differ depending on the type of information and the reason it was collected.

Information may also remain in backups for a limited period after deletion from active systems.

13. Data Security

Khinaxio Holdings uses reasonable administrative, technical, and organizational safeguards intended to protect information from unauthorized access, disclosure, alteration, destruction, or misuse.

However, no internet transmission, mobile application, database, or electronic storage system can be guaranteed to be completely secure.

Users are responsible for protecting their account credentials and should notify us if they believe their account or information has been compromised.

14. Children’s Privacy

Our Services are not intended to collect personal information directly from children under 13 without appropriate authorization.

We do not knowingly collect personal information from children under 13 in circumstances prohibited by applicable law.

If we learn that personal information from a child has been collected in violation of applicable requirements, we will take reasonable steps to delete it.

Healthcare students who use Heroes One should comply with applicable age requirements, educational institution policies, and platform requirements.

15. Your Privacy Rights

Depending on where you live, you may have certain rights regarding your personal information.

These may include the right to:

• Request access to personal information we maintain about you;
• Request correction of inaccurate information;
• Request deletion of certain information;
• Obtain information about how your information is processed;
• Request a copy of certain information;
• Withdraw consent where processing is based on consent;
• Object to or restrict certain processing where applicable;
• Exercise other rights provided under applicable law.

These rights are subject to applicable exceptions and verification requirements.

We may need to verify your identity before processing certain requests.

16. California Privacy Rights

California residents may have additional rights under applicable California privacy laws.

Depending on whether those laws apply to Khinaxio Holdings and the particular processing activity, these rights may include requests to know, access, correct, or delete personal information and rights concerning certain sharing or use of personal information.

Khinaxio Holdings will not unlawfully discriminate against individuals for exercising applicable privacy rights.

Our disclosures regarding “sale” or “sharing” of personal information should reflect the technologies actually used by our website and applications.

17. Communications

If you contact us, we may use your contact information to respond to your request.

If we send optional promotional communications, you may unsubscribe using the instructions contained in those communications.

We may still send non-promotional communications that are necessary for account administration, security, transactions, or important changes to the Services.

18. Third-Party Services and Links

Our Services may contain links to or integrate with third-party websites, platforms, or services.

Examples may include mobile application stores, authentication providers, hosting services, analytics providers, or other external resources.

Khinaxio Holdings does not control the privacy practices of independent third parties. Your interaction with those services may be governed by their own terms and privacy policies.

We encourage you to review the applicable third-party privacy policies before providing information to them.

19. Apple App Store and Google Play

Heroes One may be distributed through third-party application marketplaces such as the Apple App Store and Google Play.

Those platforms may independently collect and process information relating to downloads, purchases, subscriptions, devices, and accounts.

Their processing of such information is governed by their respective privacy practices.

Khinaxio Holdings receives only the information made available to developers by those platforms.

20. International Users

Our Services may be accessible outside the United States.

If information is transferred to or processed in a country other than the country where you reside, applicable data-protection safeguards will be used where legally required.

Privacy rights and requirements vary by jurisdiction.

21. Do Not Track and Similar Signals

Some browsers and devices provide privacy preference signals.

Our response to such signals depends on the technologies used by our Services and applicable legal requirements.

Where required by applicable law, we will recognize applicable legally required opt-out preference signals.

22. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect changes in our Services, technology, business practices, or legal requirements.

When we update the Privacy Policy, we will revise the “Last Updated” date at the top.

If changes are material, we may provide additional notice when appropriate or legally required.

We encourage users to periodically review this Privacy Policy.
