How we handle your information.

This Privacy Policy describes how Kascade Health LLC (“Kascade,” “we,” “our,” or “us”) collects, uses, and discloses information about you when you visit kascadehealth.com or use our lab interpretation and Supplement Stack Audit services (collectively, the “Service”).

01Information we collect

We collect information from the following sources:

Information you provide directly

Information collected automatically

01aNotice at collection (California residents)

This section is provided to comply with California Civil Code § 1798.100(b). At or before the point of collection, we inform you of:

01bSensitive personal information

The lab values you enter (e.g., fasting insulin, SHBG, hsCRP, etc.) may constitute sensitive personal information under California law. So does a good deal of what sits around them, and we would rather name it than leave it inside a general word:

We use your laboratory and health information to provide the Service and for other purposes described in this Privacy Policy, including security, fraud prevention, legal compliance, quality assurance and service improvement where permitted by applicable law. We do not use your lab values for any other purpose, including marketing, profiling for cross-context advertising, or training third-party AI models. The same is true of everything else listed just above. We use and disclose sensitive personal information only for purposes permitted under applicable law, including to provide the Service and for the other purposes described in this Privacy Policy. Where applicable law requires us to provide a right to limit the use or disclosure of sensitive personal information, we will provide the required notice and mechanism to exercise that right.

If you live in Washington or Nevada, the Consumer Health Data Privacy notice sets out the additional rights those states give you over this information.

01cAutomated decision-making

Your educational interpretation is generated by an AI system (Anthropic’s Claude model) using a system prompt designed and maintained by Kascade. The interpretation is educational research context based on published literature and is not a diagnostic determination, treatment recommendation, or clinical evaluation. The output may contain errors, omissions, or generalizations and should always be reviewed with a qualified healthcare provider.

We use automated systems, including Anthropic’s Claude model and Kascade-developed rules and processing logic, to analyze the information you provide and generate your educational report. Before the AI component is used, certain information is processed through Kascade’s own deterministic rules and validation logic. The resulting output is also subject to automated checks designed to identify prohibited or unsupported content and other formatting or consistency issues.

The resulting report is educational in nature and is not a diagnosis, medical treatment recommendation or clinical evaluation. Automated outputs may contain errors, omissions or generalizations and should not be relied upon as a substitute for advice from a qualified healthcare professional.

Where applicable law provides rights relating to our use of automated decision-making technology, we will provide the required notices and mechanisms for exercising those rights.

02How we use your information

We use the information we collect to:

We may also use information as reasonably necessary to establish, exercise or defend legal claims, enforce our agreements and policies, protect our rights and property, and conduct or prepare for a corporate transaction such as a merger, acquisition, financing, reorganization or sale of assets.

We don’t accept money or anything else of value in exchange for your personal information. Kascade does not provide your lab values to advertisers or data brokers, and does not use them to train its own or third-party AI models. Our current commercial arrangement with Anthropic also prohibits Anthropic from using customer inputs and outputs to train its models.

We use your information only for the purposes described in this Privacy Policy and the purposes for which it was collected.

03Who we share information with

We use third-party providers and service providers to process information on our behalf and to provide services necessary to operate the Service. Depending on the provider and the nature of the service, these providers may process information under contractual terms governing confidentiality, security and permitted use:

We may change or add service providers from time to time as our Service develops. Where required by applicable law, we will update this Privacy Policy before or when such changes take effect and provide any additional notice or choice required by law.

We may also disclose information if we believe in good faith that disclosure is required by law, regulation, legal process, or a governmental request, or to protect the rights, property, or safety of Kascade, our users, or others.

04Cookies and tracking

We currently use only strictly necessary cookies and local storage on the Service. These technologies are used as necessary for the Service to function, including remembering your preferences in your browser, temporarily storing a part-finished intake on your device for up to seven days so that you can return to and complete it, and keeping the browser you enter your access code on signed in to your report for up to 14 days. That draft remains on your device until you submit it, and you can erase it at any time using the erase function provided on the intake page.

Visit statistics. We use Netlify Web Analytics, a feature of our hosting provider, to see aggregate traffic to the Service: how many pages were viewed and which ones, approximately how many different visitors there were, roughly which countries visits came from, which websites referred visitors, and which addresses returned “page not found.” Netlify builds these statistics from the ordinary records its servers keep of each request, so no script runs in your browser for them and no cookie is set for them. Netlify estimates the number of different visitors from the IP address of each request; we see totals, not IP addresses. The statistics cover the whole site, including the intake and report pages, because Netlify cannot limit them to particular pages. They list page addresses without anything that follows a question mark, and they never include what you type into a form or the contents of your report. The link in your report email is set up so that its unique part does not appear in these statistics.

Microsoft Clarity on our public pages. On our home page and our About, FAQ and free guide pages we use Microsoft Clarity, a Microsoft service, to understand how visitors use those pages: where they click, how far they scroll, and recordings of visits to those pages, with anything typed into a form masked. Clarity sets its own cookies and is loaded from Microsoft, which processes this data under its own terms. It is not loaded on the pages where you enter health information, on your report or the pages that open it, on the Clarity Challenge request page, or on any internal tool. It runs only while Analytics is on in Cookie preferences, which you can turn off at any time, and never in a browser that sends Global Privacy Control. We discontinued Clarity on 1 September 2026 and resumed it on these public pages only on 27 September 2026.

No page-performance measurement. We do not use page-performance measurement technologies on the Service. We previously used Netlify RUM for limited page-performance measurement, but discontinued it on 11 September 2026.

If we introduce other analytics, session-recording, advertising, or similar tracking technologies in the future, we will update this Privacy Policy to describe those technologies and implement any consent, opt-out, or preference mechanisms required by applicable law.

04bYour report link, and email opens and clicks

Your report is reached by a link and a separate six-digit access code. The link travels through our email provider, Resend, which handles the delivery. Anyone holding both the link and the code can open the report, as Section 07 explains. That is true whatever the measurement settings below say, because we hand the full address of your report to Resend every time we send you one, so that it can put the link in the message.

Separately from that, an email provider can measure two things about an email: whether it was opened, and whether a link inside it was clicked. Opens are measured with a 1x1 transparent image that loads when the message is displayed. Clicks are measured by routing the links through links.kascadehealth.com, which forwards you to the real destination straight away. We look at this to judge whether the emails we send are worth sending. We use these measurements only for email-delivery and engagement purposes and do not use them for cross-context behavioral advertising.

You can tell from the email itself whether click measurement is switched on for the message in front of you. Hold your cursor over a link, or press and hold it on a phone. If the address reads links.kascadehealth.com, the click is measured. If it reads kascadehealth.com, it is not. Where it is on, that includes the email that delivers your report. What we see is that a link was clicked and when, never anything inside your report and never your lab values.

Open measurement is unreliable by design, and we treat it that way. Plenty of mail apps load that image automatically or fetch it through their own servers, so an open can be recorded when nobody read a word, and a genuine read can go uncounted when images are blocked. If you would rather not be counted, switching off automatic image loading in your mail app stops open measurement, and the unsubscribe link in every marketing email stops the emails.

This is measurement of the email itself. It is separate from the visit statistics in Section 04, and none of it runs on this website.

05How long we keep information

We retain personal information for as long as needed to provide the Service and for legitimate business purposes, including tax, accounting, and legal compliance. Generally:

We normally delete your lab values, report and related intake information 24 months after purchase unless you choose to keep your results. You can also request deletion at any time, subject to the limitations described in Section 06.

Retention periods may be extended where necessary to comply with applicable law, resolve disputes, enforce our agreements, prevent fraud or abuse, or establish, exercise or defend legal claims.

06Your rights

For California residents (CCPA / CPRA)

You have the right to:

To exercise these rights, email hello@kascadehealth.com with the subject line “Privacy Rights Request.” Requests to know, delete, or correct personal information will generally be substantively answered within 45 calendar days, subject to any extension permitted by applicable law. Requests to opt out of sale or sharing, or to limit the use or disclosure of sensitive personal information where applicable, will be processed within the timeframe required by applicable law.

For all users

You may unsubscribe from marketing emails at any time using the link in any email. You may request a copy or deletion of your data by emailing the address above.

What deletion actually reaches

When you ask us to delete your record, this is what goes:

Your report link stops working from that moment, for you and for anyone else who has it. It is not the only way access stops working: access can also expire, be revoked on its own, or be replaced when we issue a fresh link and code. Section 07 says how.

And this is what it does not reach, which we would rather you heard from us:

If you want any of those addressed, say so in the same email and we will review the request and respond in accordance with applicable law, including explaining any limitations that apply.

If we say no

You can appeal any decision we make on a privacy rights request. Reply to our decision, or write to hello@kascadehealth.com with the subject line “Privacy Appeal,” within the period permitted by applicable law or, where no specific period is prescribed, within 45 days of receiving it. Tell us what you asked for and why you think the answer was wrong. A person, not an automated process, will look at it again, and we will write back within 45 days with the decision and the reason for it.

If we deny the appeal, you can complain to your state Attorney General. Washington residents: atg.wa.gov/file-complaint. Nevada residents: the Office of the Nevada Attorney General, ag.nv.gov. California residents may contact the California Privacy Protection Agency or the California Attorney General. We will also tell you how to do this in the denial itself.

How we verify requests

To protect your information, we verify your identity before fulfilling rights requests. We may ask you to confirm your email address used at signup and at least one of: your full name as provided, the date of your most recent purchase, or other reasonably available information. We do not require account creation or government ID. We respond to verified requests within the timeframes required by applicable law. Where permitted by applicable law, we may decline to act on requests that are manifestly unfounded or excessive, or may charge a reasonable fee for such requests.

Global Privacy Control (GPC)

If your browser or a browser extension sends a Global Privacy Control signal, we read it on every page load and honor it automatically as a valid opt-out of any “sale” or “sharing” of personal information. We don’t do either. A browser that sends it also never loads Microsoft Clarity on our public pages (Section 04).

Authorized agents

You may designate an authorized agent to make a privacy rights request on your behalf. The agent must provide written authorization signed by you, and we may verify your identity directly.

06aBreach notification

If Kascade determines that a security incident constitutes a breach requiring notification under applicable law, Kascade will provide notice as required by applicable federal, state and other applicable law. Where required, notices will describe the nature of the incident, the categories of information affected, the measures taken in response and steps individuals may take to protect themselves.

07Security, and how your report is actually reached

Your report is accessed through a private link we email you, and opening it also requires a six-digit access code that we send in a separate email. There is no password, because there is no account to attach one to.

Alongside that we take reasonable measures to protect the information while we hold it: we maintain administrative, technical and organizational safeguards designed to protect personal information against unauthorized access, disclosure, alteration or destruction, including access controls and encryption in transit, as appropriate to the nature of the information and the risks associated with its processing. No system is perfectly secure, and we cannot guarantee the absolute security of information transmitted over the internet. If you have reason to believe your interaction with us is no longer secure, please contact us immediately.

08Children

The Service is intended for users 18 years of age or older. We do not knowingly collect personal information from children under 18. If we learn that we have collected information from a child under 18, we will delete it promptly. If you believe a child under 18 has provided information to us, please contact hello@kascadehealth.com.

09International users

The Service is operated from the United States and is intended solely for users physically located in the United States. We do not currently offer the Service to residents of the European Economic Area or the United Kingdom or to users physically located outside the United States.

10Changes to this policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you by email (if you have provided one) and post the updated policy on the Service with a new effective date.
