Cancellation policy

Last updated: September 8, 2026

This policy applies to H3O subscriptions purchased at h3ofuel.com, operated by NUTRIVA LABS LLC. A one-time purchase does not start a subscription.

Recurring orders and charges

When you choose Subscribe & Save, you authorize recurring charges to your selected payment method for the products and delivery frequency shown at checkout. Your subscription renews automatically at that frequency until you cancel. The product price, discount, shipping charge and applicable tax are shown before you confirm your purchase. Shipping charges apply to each subscription delivery.

Checkout's Recurring subtotal is shown before applicable discounts, shipping and tax. Bundle discounts appear separately in the order summary. Our subscription bundle discounts apply to recurring deliveries while the bundle meets the offer's quantity conditions; reducing the quantity can change the discount and amount due.

You can review your subscription details and next scheduled order in your account. We will notify you before a change to your recurring price takes effect, and you can cancel before that charge.

Pause, skip or cancel online

  1. Open Manage subscriptions and sign in using the email address used for your order. Shopify emails you a sign-in code.
  2. Select your subscription in the Subscriptions tab.
  3. Choose the available action to skip an upcoming order, pause the subscription or cancel it, and confirm your choice. Check the confirmation and updated subscription status.

There is no minimum number of renewals and no cancellation fee. Canceling stops future subscription charges and orders. Pausing stops future charges and orders until you resume; skipping applies to the selected upcoming order.

Make changes before the next scheduled charge to prevent that order from being created. Canceling, pausing or skipping does not automatically reverse a charge or cancel an order already created. If an order has just been charged, contact us promptly so we can check whether it can still be stopped before fulfillment.

Help managing your subscription

If you cannot access your account or would like us to help, email info@h3ofuel.com with the email address used for your order and your request. You can also call +1 (917) 730-9620. Support hours are Monday–Saturday, 9am–5pm Eastern Time. We aim to reply within one business day during that schedule. Online management is available outside support hours.

Returns and refunds

Each subscription delivery is covered by our Return & Refund Policy: request a normal return within 30 calendar days after delivery; products must be unopened, unused and in their original packaging with all seals intact. A return or refund request does not cancel future subscription deliveries. Damaged, incorrect or defective orders are handled separately under that policy.
