Legal & Privacy.

1. Overview

HashCare is operated by SolvingHealth LLC, a Colorado limited liability company. This page covers our Terms of Use, how we handle your data, and how to reach us.

HashCare is in pre-launch. The service described on this site is in active development and not all features are live. This page is a living document — we update it as the product changes and will mark the "Last updated" date at the top whenever we do.

2. Terms of Use

By using HashCare you agree to the following. If you do not agree, please do not use the service.

What HashCare is

HashCare provides cryptographic identity tooling for health records — a way to hold, share, and revoke access to your own data. HashCare is not a substitute for medical advice, diagnosis, or treatment. Always consult a licensed healthcare provider for medical decisions.

What you agree to

• You will use HashCare only for lawful purposes and only as permitted by these Terms.
• You will not attempt to gain unauthorized access to any system, account, or data that is not yours.
• You are responsible for keeping your login credentials and cryptographic keys secure.
• You will not upload content that violates third-party rights, contains malware, or violates applicable law.

Service availability

HashCare is provided "as is" during the pre-launch period. We may add, change, suspend, or discontinue features without notice. We make no warranty that the service will be uninterrupted, error-free, or free of security vulnerabilities during development.

Limitation of liability

To the maximum extent permitted by law, SolvingHealth LLC, its affiliates, officers, and agents are not liable for any indirect, incidental, consequential, or punitive damages arising from your use of HashCare. Our total liability, for any claim arising out of these Terms, is limited to the amount you have paid us in the prior twelve months, or one hundred US dollars, whichever is greater.

3. Privacy

Our approach to privacy is narrow and specific, not broad and vague.

What we collect

• Account data: email, optional name, and authentication credentials you provide.
• Usage data: page views, clicks, approximate location at city level, and device/browser type, for debugging and product improvement.
• Health data you choose to add: only what you add, and only what you explicitly share. Your private vault is end-to-end encrypted.

What we do not do

• No sale of personal data. Ever. Not to advertisers, not to data brokers, not to insurers.
• No training on your data without consent. AI training on your health data only happens with explicit opt-in, per record.
• No third-party ad tracking. This site uses first-party analytics only.

Your rights

• Export your data at any time in a standard format.
• Delete your account and have your data removed from our active systems within thirty days.
• Request a copy of what we know about you.
• Revoke any prior consent to share, attest, or use your data.

Residents of California, Colorado, Virginia, Connecticut, and Utah have additional rights under state privacy laws (CCPA/CPRA, CPA, VCDPA, CTDPA, UCPA). We honor those rights for every HashCare user regardless of state.

4. Health Data & HIPAA

HashCare is designed for individuals to hold their own health data. As a general matter, an individual managing their own records is not a "covered entity" under HIPAA, and HashCare does not act as a covered entity by default.

When HashCare connects to a covered entity on your behalf (for example, to pull records from a provider's patient portal), that provider remains the covered entity. HashCare acts as your authorized user, not as a business associate, unless a separate Business Associate Agreement has been signed.

If you are a provider, payer, or vendor who needs HashCare to operate as a business associate, contact us — we will execute a BAA and scope accordingly.

5. Intellectual Property

The HashCare name, logo, and site design are the property of SolvingHealth LLC. Content you add to HashCare remains yours — we claim no ownership of your data, your identity, or your cryptographic keys.

Feedback you send us may be used to improve the product without obligation to you, unless we have a separate agreement.

We respond to verified privacy requests within thirty days. For urgent security disclosures, please mark your email Security Disclosure in the subject line.

7. The Anchor Registry

hashcare.com/anchor lets anyone anchor the SHA-256 fingerprint of a document to a public registry. The document itself is hashed in your browser and is never transmitted to or stored by us — we receive only the 64-character fingerprint, an optional label you write, and a timestamp.

Labels are public. Anything you type in the label field can be seen by anyone who verifies that hash. Do not put personal, confidential, or identifying information in a label. Labels are reviewed before appearing in the site's public list; direct hash lookups return the label as submitted, marked as user-supplied.

Hashes cannot be reversed into documents, and anchors are designed to be permanent — that is what makes them proof. If a label contains content that should be removed (personal information, abuse, unlawful content), request removal via solvinghealth.com/legal; we will remove or blank the label while preserving the hash and timestamp where legally possible.

Anchoring proves that a document with a given fingerprint existed at a point in time. It is not a clinical signature, notarization, copyright registration, or legal advice.
