Important Notice Regarding Patient and Medical Information

Please do not include patient names, test results, medical histories, photographs of completed tests that identify an individual, or other protected health information in website forms, product reviews, emails, or general customer-service communications.

If product-performance support requires information about a particular test, please provide only the minimum information requested, such as the product name, lot number, expiration date, and a de-identified description of the issue.

Information processed by Shopify may also be subject to Shopify’s Consumer Privacy Policy.

We may also use other service providers to support website functionality, customer communications, analytics, security, sales, marketing, shipping, and other business operations.

Cookies and Similar Technologies

Kay Scientific and our service providers may use cookies, pixels, tags, local storage, and similar technologies to operate and secure our website, maintain shopping-cart and account functionality, remember preferences, understand website usage, measure marketing performance, and support analytics or advertising.

Some cookies are necessary for the website to function. Other cookies may be used for analytics, personalization, or advertising, depending on the tools and settings active on our website.

Where available, you may manage non-essential cookies through the cookie-preference or privacy controls displayed on our website. You may also manage cookies through your browser settings.

Disabling certain cookies may affect website functionality, saved preferences, account access, or checkout features.

How We Disclose Personal Information

We may disclose personal information to the following categories of recipients when reasonably necessary.

E-Commerce and Technology Providers

This includes Shopify and providers that support website hosting, cloud services, data storage, account functionality, information technology, security, and technical operations.

Payment and Financial-Service Providers

Payment processors, banks, financing providers, fraud-screening services, and other parties may process information necessary to authorize and complete transactions.

Shipping and Fulfillment Providers

We may disclose information to shipping carriers, fulfillment partners, manufacturers, distributors, and logistics providers to process, ship, track, and deliver orders.

Sales and Customer-Service Providers

We may use customer-relationship-management, telephone, email, customer-support, and communication platforms to manage accounts and respond to customers.

Analytics, Marketing, and Advertising Providers

We may disclose certain online identifiers, device information, website activity, and marketing-interaction information to service providers that help us understand website usage, communicate with customers, measure marketing performance, or support advertising.

Depending on the technology used and applicable state law, certain advertising-related disclosures may be considered a “sale,” “sharing,” or use for targeted advertising even when Kay Scientific does not receive money in exchange for the information.

Manufacturers, Suppliers, and Business Partners

When necessary to answer product questions, investigate product-performance concerns, administer warranties, process recalls, fulfill special orders, or resolve customer-service matters, we may disclose relevant information to manufacturers, suppliers, or other business partners.

Professional Advisers

We may disclose information to attorneys, accountants, insurers, auditors, consultants, and other professional advisers when reasonably necessary.

Government and Legal Recipients

We may disclose information when we reasonably believe it is necessary to:

  • Comply with applicable law
  • Respond to subpoenas, court orders, or valid legal requests
  • Cooperate with regulatory or law-enforcement authorities
  • Protect our rights, property, customers, employees, or others
  • Investigate fraud, security incidents, or unlawful activity

Business Transactions

Personal information may be disclosed or transferred as part of a merger, acquisition, financing, reorganization, bankruptcy, sale of assets, or other business transaction or proposed transaction.

Sale, Sharing, and Targeted Advertising

Kay Scientific does not disclose personal information in exchange for money in the traditional sense.

However, certain online advertising, analytics, cookies, pixels, or similar technologies may be treated as a “sale,” “sharing,” or targeted advertising under some state privacy laws.

Where applicable law provides you with the right to opt out of certain sales, sharing, or targeted advertising, you may use the Your Privacy Choices link or cookie-preference tool available on our website. You may also contact us at info@kayscientific.com.

We do not knowingly sell or share the personal information of individuals under 16 years of age.

Global Privacy Control and Browser Signals

Some browsers and browser extensions allow you to send privacy-preference signals, such as the Global Privacy Control, indicating that you wish to opt out of certain data sales or sharing.

Where required by applicable law and supported by our systems, we will treat a recognized opt-out preference signal as an opt-out request for the browser or device sending the signal.

Because there is not currently a universally accepted standard for all “Do Not Track” signals, our website may not respond to every browser-based Do Not Track setting.

Marketing Communications

Where permitted by law, we may send newsletters, product announcements, educational information, promotions, and other marketing communications.

You may unsubscribe from promotional emails at any time by selecting the unsubscribe link included in the message or by contacting us at info@kayscientific.com.

Please allow a reasonable period for your preference to be processed.

Even after unsubscribing from marketing communications, you may continue to receive non-promotional communications, including:

  • Order confirmations
  • Shipping notifications
  • Account notices
  • Product-safety or recall information
  • Responses to customer-service requests
  • Other transactional or legally required communications

Data Retention

We retain personal information only for as long as reasonably necessary for the purposes described in this Privacy Policy, including to:

  • Provide products and Services
  • Maintain order, tax, accounting, and transaction records
  • Support warranties, quality investigations, and product recalls
  • Resolve disputes
  • Prevent fraud
  • Enforce agreements
  • Comply with legal and regulatory requirements
  • Protect legitimate business interests

Retention periods vary depending on the type of information, our relationship with you, legal requirements, operational needs, and whether the information is needed for an ongoing claim, dispute, investigation, or security matter.

When personal information is no longer reasonably required, we may delete, anonymize, or securely dispose of it, subject to applicable law and technical limitations.

Data Security

We use reasonable administrative, technical, physical, and organizational safeguards designed to protect personal information.

These measures may include access controls, account authentication, secure service providers, payment-processing protections, employee practices, monitoring, and other security measures appropriate to the nature of the information.

However, no website, transmission method, network, or electronic-storage system can be guaranteed to be completely secure. We cannot guarantee absolute security.

You are responsible for keeping account credentials confidential and using appropriate security practices when communicating with us.

Your Privacy Rights

Depending on where you live and subject to applicable exceptions, you may have the right to:

  • Confirm whether we process your personal information
  • Request access to personal information we maintain about you
  • Request correction of inaccurate personal information
  • Request deletion of certain personal information
