Terms of Service

• You own and control your health data at all times.
• You are responsible for deciding whether and how to share your data.
• You are responsible for maintaining the security of your Solana wallet and any connected authentication credentials (including Google or Apple OAuth accounts used through Phantom's embedded wallet). Arxova is not responsible for unauthorized access resulting from your failure to secure your wallet or credentials.
• You agree to provide accurate information when creating or managing your account.

Arxova™ is a health data aggregation, ownership, and consent-management platform. We do not provide medical advice, diagnosis, or treatment. Nothing in the Service should be interpreted as a substitute for professional medical advice. Always consult a qualified healthcare provider regarding any health conditions or before making health-related decisions.

ARIA, our AI health assistant, provides informational insights based on your personal health data. ARIA is not a medical device, is not FDA-cleared or approved, and its outputs should never be used as the basis for clinical decisions. You agree not to rely on ARIA outputs in place of professional medical consultation.

Arxova™ uses blockchain technology to establish provenance and verifiable ownership of health records. When health data is stored or permissioned through the platform, a cryptographic record is written to the Solana blockchain — creating an immutable, timestamped proof that:

• The record exists and has not been tampered with.
• You, the patient, authorized its creation or use.
• Consent was granted or revoked at a specific point in time.

This does not expose your raw health data publicly. The blockchain functions as a permission and provenance ledger only.

For permanent encrypted storage, Arxova offers integration with the Arweave network. Data stored on Arweave is encrypted on your device before upload. Arxova holds no decryption keys. Because Arweave is a permanent network, data stored there cannot be deleted — this is disclosed clearly before use and requires your explicit, separate consent.

If you choose, you may be invited to participate in research studies run by external institutions. Each study is governed by that institution's IRB-approved consent, which you review and sign separately before any data is shared.

• Any compensation for participation is set and paid by the research institution, handled through a separate, licensed payments provider — not by Arxova.
• Arxova does not pay you for your data, does not sell your data, and takes no percentage of any compensation you receive.
• Arxova's role is limited to infrastructure: aggregation, consent management, and secure transfer. Arxova's revenue comes solely from platform fees charged to institutions, never from a cut of your data or your compensation.
• Participation is entirely opt-in. You control which data is shared with a given study and may withdraw at any time in accordance with that study's consent.
• You are solely responsible for any tax obligations arising from compensation you receive from a research institution.

Arxova is building a feature that will let you optionally share health data with research institutions running approved studies. This feature is not currently active. When it launches:

• Participation will be entirely opt-in and governed by the study's IRB-approved consent, which you review and sign.
• Any compensation is set and paid by the research institution through a separate, licensed payments partner — never by Arxova, and Arxova takes no percentage of it.
• You may withdraw from any research data sharing arrangement at any time.
• Arxova does not sell your data, is not a data broker, and does not share any health data for research purposes without your explicit, affirmative action.

You agree not to use the Service to:

• Share data unlawfully or in violation of any third-party rights.
• Access another user's data without their consent, or attempt to tamper with the platform or its infrastructure.
• Circumvent applicable law, including HIPAA, GDPR, CCPA, or any applicable financial regulations.
• Reverse engineer, decompile, disassemble, or otherwise attempt to extract source code from the platform.
• Use automated tools to scrape, mine, or extract data from the platform without prior written permission from Arxova.
• Use ARIA's outputs as a substitute for professional medical advice or for clinical decision-making without the involvement of a qualified healthcare provider.
• Use the platform if you are under 18 years of age.

Arxova reserves the right to suspend or permanently terminate your account, with or without notice, if you violate these Terms, engage in fraudulent or abusive behavior, or use the Service in any manner that causes harm to other users, third parties, or Arxova. Upon termination, your right to use the Service ceases immediately. Sections of these Terms that by their nature should survive termination (including Sections 2, 3, 8, 9, 10, and 11) will remain in effect.

Arxova™ is a trademark of HealthKey Labs, LLC. The platform, including its software, design, and content, is Patent Pending (U.S. Provisional Patent Application Serial No. 64/010,350). All rights not expressly granted to you in these Terms are reserved by HealthKey Labs, LLC. You may not use the Arxova name, logo, or trademarks without prior written permission.

• Arxova™ provides technology “as is,” without warranties of any kind, express or implied.
• We are not liable for misuse of data by third parties once you have authorized its release.
• We are not liable for losses arising from blockchain transactions, wallet loss, stablecoin-issuer actions, or third-party service failures (including Fasten Health or wearable integrations).
• To the maximum extent permitted by applicable law, Arxova's total liability for any claim arising under these Terms shall not exceed the amount you paid to Arxova in the twelve (12) months preceding the claim.

These Terms are governed by the laws of the State of Florida, without regard to its conflict of law provisions.

Mandatory Arbitration. Except for claims that qualify for small claims court, any dispute, claim, or controversy arising out of or relating to these Terms or the use of the Service — including any question regarding existence, validity, or termination — shall be resolved exclusively by binding arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules (or Commercial Arbitration Rules where applicable), as then in effect. The arbitration shall be conducted in Miami-Dade County, Florida, or remotely if mutually agreed. The arbitrator's decision shall be final and binding, and judgment on the award may be entered in any court of competent jurisdiction.

Class Action Waiver. You agree that any arbitration shall be conducted on an individual basis only. You waive any right to bring or participate in a class action, collective action, or representative proceeding of any kind. Claims of two or more users may not be consolidated or joined in any arbitration without the written consent of all parties.

Exceptions. Either party may seek emergency injunctive or equitable relief in the state or federal courts located in Miami-Dade County, Florida, to prevent irreparable harm pending arbitration. This arbitration agreement does not preclude you from filing a complaint with applicable regulatory agencies (including HHS, FTC, or state attorneys general).

Costs. AAA filing fees are governed by the applicable AAA fee schedule. Arxova will pay arbitration costs that exceed what you would pay to file in small claims court for claims that are not frivolous.

The Arxova™ website uses cookies to personalize your experience and support platform functionality. By accessing Arxova™, you agree to the use of required cookies. A cookie is a small text file placed on your device by a web server. Cookies cannot execute programs or deliver viruses. They are uniquely assigned to you and readable only by the issuing domain.

We may use cookies to collect anonymized usage data for service improvement. You may accept or decline optional cookies through your browser settings. Required cookies necessary for platform operation do not require your consent, as they are essential to functionality.

We may update these Terms from time to time. For material changes — including changes to how your data is handled, new token mechanics, or new integrations involving PHI — we will notify you through the app and require your affirmative re-acceptance before you can continue using the Service. Non-material changes will be reflected in the “Last Updated” date. Your continued use of the Service after non-material changes are posted constitutes your acceptance of the updated Terms.
