Privacy Policy

Last updated: July 2, 2026

Human3 (“Human3,” “we,” “us,” or “our”) operates the longevity data commons — an open platform where people submit protocols, bloodwork, and results, and the community verifies them into evidence anyone can check. Because our platform handles health information, your privacy is fundamental to how we build. This policy explains what we collect, how we use it, when it becomes public, and the choices you have.

The short version

01Information we collect

We collect information you provide directly, information generated as you use the platform, and information from third-party services you connect.

Account & identity

When you create an account we (and our authentication provider) process your email address and/or the address of your embedded or connected wallet. You may add a display name, avatar, or profile details.

Health & research data

To participate in the commons you may submit health-related information, including bloodwork and lab reports, biomarker values, protocols, compounds and doses, timelines, wearables or self-reported metrics, and notes describing your experiments and outcomes.

Content & community activity

We process the submissions, reviews, verifications, votes, comments, and reputation associated with your account, along with the points and rewards you earn for contributions.

Connected accounts

If you link a social account (such as X/Twitter) or another service, we receive the identifiers and profile data that service shares with us, subject to your permissions there.

Usage, device & log data

Like most online services, we automatically collect technical data such as IP address, device and browser type, pages viewed, actions taken, timestamps, and referring pages. We also use signals to help detect and prevent fraud and abuse (for example, duplicate-account or “sybil” activity).

Cookies & similar technologies

We use cookies and similar technologies to keep you signed in, remember preferences, secure the platform, and understand usage. You can control cookies through your browser settings; some features may not work without them.

02How we use information

Where required by law, we rely on legal bases such as your consent (including explicit consent for health data), performance of a contract, our legitimate interests, and legal obligation.

03Health & sensitive data

Bloodwork, biomarkers, and related health information are sensitive. We process this information only to provide the platform’s core functions — verification, publication (when you choose), and research features — and, where the law requires, only with your explicit consent, which you may withdraw at any time.

Raw health files and identifiable medical data are stored encrypted and off-chain. We minimize what we collect, restrict internal access, and never place raw medical data in anything the public site or blockchain can read.

Human3 does not provide medical advice, diagnosis, or treatment. Nothing you submit or read on the platform is a substitute for professional medical care.

04Blockchain & on-chain data

Human3 is built on the Base blockchain. To make results independently checkable, we write cryptographic hashes and attestations — not your raw data — to the chain. A hash lets anyone confirm that a result has not been altered without revealing the underlying medical file.

Information recorded on a public blockchain, and any wallet address associated with it, is public, immutable, and permanent. It cannot be changed or deleted by us or anyone else, and on-chain activity may be linkable to your wallet. Please consider this before you publish.

05Automated processing & AI

We use automated tools — including optical character recognition (OCR) and AI models — to read lab documents, extract biomarker values, screen for tampering, and assist verification. These tools support human and community review; you can contact us if you believe an automated decision about your submission was made in error.

06The public commons

The commons is open by design. When you choose to publish a protocol or a verified result, the associated content — such as the compound, dose, biomarker changes, verification status, and your chosen public handle — becomes publicly visible and may be browsed, cited, aggregated, or replicated by others.

You control what you publish. Content that you keep private is not published to the commons, though metadata and attestations you have already committed on-chain remain permanent as described above.

07How we share information

We do not sell your personal information. We share information only as described here:

08Data retention

We keep personal information for as long as your account is active or as needed to provide the platform, and thereafter only as necessary to meet legal, accounting, security, or dispute-resolution obligations. Off-chain data can be deleted or anonymized on request, subject to those obligations. Data already committed to the blockchain cannot be deleted.

09Your rights & choices

Depending on where you live, you may have the right to:

To exercise any of these rights, contact us at hello@human3.app. We will respond within the timeframes required by applicable law and may need to verify your identity first. You also have the right to lodge a complaint with your local data-protection authority.

10Security

We use administrative, technical, and organizational safeguards — including encryption of sensitive data, access controls, and monitoring — designed to protect your information. No method of transmission or storage is perfectly secure, so we cannot guarantee absolute security. Keep your wallet keys and login credentials confidential; anyone with access to them may access your account.

11International data transfers

Human3 operates globally, and your information may be processed in countries other than your own, where data-protection laws may differ. Where required, we use appropriate safeguards (such as standard contractual clauses) for cross-border transfers.

12Children’s privacy

The platform is intended for adults aged 18 and over. We do not knowingly collect personal information from anyone under 18. If you believe a minor has provided us information, contact us and we will delete it.

13Third-party links & services

The platform may link to or integrate third-party sites and services, including wallet providers, social networks, and partners. Their privacy practices are governed by their own policies, and we encourage you to review them.

14Changes to this policy

We may update this policy from time to time. When we make material changes, we will update the “Last updated” date above and, where appropriate, provide additional notice. Your continued use of the platform after an update means you accept the revised policy.
