Terms of Service

Last updated: November 1, 2026

1. About these terms

Welcome to Heartfield. Heartfield is operated by HEYKURL LLC ("Heartfield", "we", "us", "our"). These Terms of Service apply when you visit tryheartfield.com or buy from us. By using our website or placing an order, you agree to these terms and to the policies they refer to: our Refund Policy, Shipping Policy, Subscription Policy and Privacy Policy. If you don't agree, please don't use the website.

Please read section 15 carefully. If you live in the United States, it requires you to resolve disputes with us through individual binding arbitration, not in court, and it waives your right to a jury trial and to take part in a class action. You can opt out within 30 days of your first order (see section 15).

2. Who can buy

You must be at least 18 years old and have a shipping address in the United States, United Kingdom, Canada or Australia to place an order. By ordering, you confirm that the information you give us is true and complete.

3. Health information

Heartfield products (Heartfield Nattokinase and Heartfield R-Alpha Lipoic Acid) are dietary supplements. The statements on this website have not been evaluated by the Food and Drug Administration. Our products are not intended to diagnose, treat, cure, or prevent any disease.

The information on this website is for general information only and is not medical advice. Talk to your doctor before taking any supplement, especially if you take medication (including blood thinners, daily aspirin, or medication for blood pressure or blood sugar), are pregnant or nursing, have a medical condition, or are scheduled for surgery. Do not exceed the suggested use. Stop using the product and talk to your doctor if you have any reaction. Individual results vary.

4. Products and prices

We do our best to show our products, prices and availability accurately. Prices are shown in your local currency (US dollars, British pounds, Canadian dollars or Australian dollars). Offers and bundle prices can change at any time. If we make a mistake in a price or product description, we may correct it, and we may cancel an order placed at the wrong price. If that happens after you've paid, we refund you in full.

We may limit quantities or refuse or cancel any order, for example when we suspect fraud or resale.

5. Orders and payment

When you place an order, you authorize us and our payment providers to charge your payment method for the total shown at checkout. Your order is accepted when we send your shipping confirmation.

6. Subscriptions

Every order includes a subscription refill: the bottles or pouches you paid for in your first order (free bottles, pouches and gifts are not repeated), charged to your payment method every 28 days, starting 28 days after your first order, at the same price you paid, as shown in our Subscription Policy, until you cancel. Each refill ships about 2 days after it is charged. We email you 3 days before each refill. You can skip, delay or cancel at least 24 hours before your refill date. Full details are in our Subscription Policy.

7. Shipping, refunds and returns

Shipping is covered by our Shipping Policy. Refunds and our 90-Day Money-Back Guarantee are covered by our Refund Policy. The risk of loss passes to you when your order is delivered.

8. Reviews and content you send us

If you send us a review, photo, comment, or message, you confirm it is honest and yours to share, and you give us permission to use it, without payment, to run and promote Heartfield. We may edit for length or remove any content at our discretion. Please don't post anything unlawful, misleading, or offensive.

9. Our content

All content on this website, including text, images, logos, and designs, belongs to Heartfield or its licensors. You may not copy, reuse, or sell it without our written permission.

10. Acceptable use

You agree not to misuse the website, including by attempting to gain unauthorized access, interfering with its operation, using it for anything unlawful, or placing fraudulent orders.

11. Third-party services

Our store runs on Shopify, subscriptions are managed through Loop, and payments are handled by third-party payment providers. Their own terms and privacy policies apply to the services they provide. We're not responsible for third-party websites we link to.

12. Disclaimer

Except for the promises in our Refund Policy, the website and our products are provided "as is" and "as available". To the fullest extent allowed by law, we disclaim all other warranties, express or implied, including warranties of merchantability and fitness for a particular purpose.

13. Limitation of liability

To the fullest extent allowed by law, Heartfield and its owners, employees, and partners are not liable for any indirect, incidental, special, or consequential damages arising from your use of the website or our products. Our total liability for any claim is limited to the amount you paid for the order that the claim relates to.

14. Indemnification

You agree to hold Heartfield harmless from any claims, losses, or costs, including reasonable legal fees, that arise from your breach of these terms or your misuse of the website.

15. Disputes, arbitration and class action waiver

Talk to us first. If you have a problem, please email us at support@try-heartfield.com with your name, the email you ordered with and what you would like us to do. You and we agree to try in good faith to solve it together for 30 days before either of us starts an arbitration or a court case.

If you live in the United States, the rest of this section applies to you:

a. Individual binding arbitration. Any dispute or claim between you and Heartfield that relates to the website, your orders, your subscription, our products or these terms will be resolved by binding arbitration instead of in court, except as described in (d) below. The arbitration is run by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, in front of one arbitrator. It can take place online, by phone, by written submissions or in person in the county where you live. The arbitrator can award you the same individual relief a court could. For claims under $10,000, we pay the AAA filing, administration and arbitrator fees, unless the arbitrator finds the claim was frivolous.

b. No class actions. You and we may each bring claims only on an individual basis, and not as a plaintiff or class member in any class, collective, consolidated or representative action. The arbitrator may not combine the claims of more than one person and may only give relief to the individual person bringing the claim.

c. No jury trial. You and we both give up the right to a jury trial.

d. Exceptions. Either of us may bring an individual claim in small claims court if it qualifies. Either of us may also go to court to stop misuse of our intellectual property.

e. Mass filings. If 25 or more similar arbitration demands are filed against us by or with help from the same law firm or group, they will be handled in batches of up to 25 demands, with one arbitrator per batch, and the AAA fees will be charged per batch. You and we agree to work in good faith with the AAA on this process.

f. Opting out. You can opt out of this arbitration agreement within 30 days after your first order. Email support@try-heartfield.com with the subject "Arbitration Opt-Out", your full name and the email you ordered with. Opting out does not change anything else in these terms.

g. Other. This section is governed by the Federal Arbitration Act. If the class action waiver in (b) is found to be unenforceable for a particular claim, that claim (and only that claim) will be decided in court, and the rest of this section stays in effect. This section continues to apply after your subscription ends or you stop using the website.

If you live outside the United States (United Kingdom, Canada or Australia), sections (a) to (g) do not apply to you. You may bring a claim in the courts of the country where you live.

Governing law. These terms are governed by the laws of the State of Wyoming, United States, without regard to its conflict of law rules. Any dispute that is not handled by arbitration or small claims court will be handled by the state or federal courts located in Wyoming, unless you live outside the United States. Nothing in these terms takes away rights you have under the consumer laws of the country you live in.

Time limit. Any claim relating to the website, your orders or these terms must be brought within one (1) year after it arises, unless the law where you live requires a longer period.

16. Changes to these terms

We may update these terms from time to time. The version on this page applies to orders placed after the date at the top. Using the website after a change means you accept the updated terms. If we make a material change to section 15, it will not apply to a dispute you already told us about before the change.
