Privacy Policy

Last Updated: August 7, 2026

This Privacy Policy explains how the Testing Group collects, uses, stores, and shares information when you use our website or participate in a laboratory testing group submission.

Our service is limited to coordinating individual testing requests into larger group submissions for testing by an independent third-party laboratory.

1. Information We Collect

We may collect information you provide directly to us, including:

We may also collect limited technical information when you use the website, such as:

2. Sample and Vendor Information

You are not required to disclose the vendor, seller, manufacturer, or source of your sample to us unless that information is required to complete the laboratory submission.

If you voluntarily provide vendor, batch, lot, or source information, we will use it only for purposes reasonably related to your testing request unless you authorize another use.

We do not independently verify vendor or batch information provided by participants.

3. How We Use Your Information

We may use your information to:

We do not use sample submission information to make medical, health, treatment, or diagnostic decisions.

4. Information Shared With the Laboratory

We may provide the independent laboratory with information reasonably necessary to perform the requested test.

Depending on the laboratory and requested test, this may include:

We will generally avoid providing unnecessary personal information to the laboratory.

Whenever practical, samples may be identified using a submission number or other identifier rather than the participant's personal information.

5. Payment Information

Payments may be processed by third-party payment providers.

We generally do not receive or store your complete credit card number, bank account number, or other full payment credentials when payment is handled by an external payment processor.

Payment providers process information according to their own privacy policies and security practices.

We may retain transaction information such as:

6. Service Providers

We may use third-party service providers to operate the website and coordinate submissions, including providers for:

These providers may access information only as reasonably necessary to perform services for us or as otherwise permitted by law.

7. We Do Not Sell Personal Information

We do not sell personal information for money.

We also do not sell participant lists, testing records, vendor information, laboratory results, or submission information to vendors or marketers.

If our data practices change in a way that creates additional privacy rights or opt-out obligations, this Privacy Policy will be updated accordingly.

8. Advertising

We do not use laboratory testing information, COAs, vendor information, or sample information for targeted advertising.

We do not provide laboratory submission information to advertisers for advertising purposes.

9. Cookies and Analytics

The website may use cookies or similar technologies necessary for:

If we use third-party analytics services, those services may collect technical information about how visitors use the website.

Where required by applicable law, we will provide appropriate choices regarding non-essential cookies or tracking technologies.

10. Laboratory Results

K2 Testing stores only the lab-issued HTTPS URL associated with your submission. We do not download, upload, host, copy, parse, or store the laboratory report or COA file itself.

The report remains hosted by the independent laboratory. Access to the saved link is restricted to the participant associated with the submission and authorized administrators, and it may be delivered to the submission email address.

Unless otherwise disclosed, we will not intentionally make an individual participant's test results public without permission.

If you choose to publish, share, post, or distribute your own laboratory report or COA, that disclosure is controlled by you.

11. Public or Shared Testing

Certain testing programs may specifically involve participants agreeing to publicly share laboratory results for transparency or community research purposes.

If a submission is intended to produce a public result, we will disclose that before submission.

Participation in a public-result program will not automatically authorize publication of your personal contact information.

12. How Long We Keep Information

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

Different categories of information may be retained for different periods.

Information that is no longer reasonably necessary may be deleted, anonymized, or aggregated.

13. Data Security

We use reasonable administrative, technical, and organizational measures intended to protect personal information from unauthorized access, loss, misuse, alteration, or disclosure.

However, no internet transmission, database, email system, or electronic storage method can be guaranteed to be completely secure.

Participants should avoid sending unnecessary sensitive personal information through email, chat, or submission forms.

14. Your Choices

Depending on where you live and applicable law, you may have the right to request:

Some information may need to be retained despite a deletion request, including records necessary for legal, accounting, fraud-prevention, transaction, or dispute-resolution purposes.

15. California Privacy Rights

California residents may have additional rights under the California Consumer Privacy Act, as amended, if the law applies to our business or processing activities.

Applicable rights may include the right to:

Submitting a privacy request does not affect your ability to participate in ordinary testing services except where the requested deletion or restriction would make it impossible to complete an active submission.

16. Privacy Requests

You may submit a request regarding your personal information using the contact information provided on the website.

We may need to verify your identity before completing certain requests.

For example, we may ask you to confirm information associated with your account, email address, transaction, or testing submission.

We will respond to valid requests within the time required by applicable law.

17. Sensitive Personal Information

Please do not provide unnecessary sensitive personal information.

The Testing Group does not need information such as:

Laboratory testing coordinated through this service is sample testing and is not intended to create a medical record about the participant.

The service is not intended to collect protected health information for healthcare treatment purposes.

Do not send medical histories, diagnoses, prescription records, or similar healthcare information unless specifically requested for a lawful and necessary purpose.
