Cancellation policy

Last updated: 18 September 2026

This Cancellation Policy explains how OnyGuard subscriptions work, how to change or cancel one, and how to cancel a one-time order. It forms part of our Terms of Service and should be read alongside our Return & Refund Policy.

OnyGuard is operated by Prolong Lab, UAB.

In short


Can I cancel any time?	Yes. There is no minimum term, no commitment and no cancellation fee.
How?	The Manage Subscription link in any OnyGuard email, your account, email, or telephone.
When?	At least 24 hours before your next billing date to avoid that charge.
Will anyone try to talk me out of it?	No. We will not require a call, a chat or a retention offer before cancelling.
What about an order already sent?	It cannot be cancelled, but it can be returned.

1. What a subscription is

When you choose a subscription or "subscribe and save" option at checkout, you are signing up to an automatically renewing plan. You authorise us to charge your payment method on a recurring basis, at the interval and price shown to you at checkout, until you cancel.

Before you pay, we show you clearly:

the price of each recurring shipment;
how often you will be charged and how often product will arrive;
that the plan continues automatically until you cancel; and
how to cancel.

Your agreement to those subscription terms is collected separately from the rest of your order, so it is always a deliberate choice.

2. How to cancel, pause or skip

You can do all of the following at any time, as often as you like:

Skip the next shipment
Pause the subscription
Change the delivery interval, quantity or product
Change the payment method or delivery address
Cancel the subscription entirely

Ways to do it

Method	How
Manage Subscription link	In your order confirmation email and in every renewal reminder we send. This is the fastest route and works for every subscription.
Your account	Log in at onyguard.com and open your subscriptions.
Email	support@onyguard.com — include your order number.
Telephone	+1 (888) 530-7470 (toll-free, United States).

Cancelling is as easy as subscribing. We will not ask you to complete a retention call, speak to an agent, accept an offer, post a letter, or take any step more difficult than the step you took to sign up. If you cancel online, it takes effect online.

We confirm every cancellation by email. If you do not receive a confirmation within one business day, contact us — do not assume the cancellation failed, but do let us know so we can check.

3. Cancellation timing

Cancel at least 24 hours before your next billing date to avoid being charged for that cycle.

Your next billing date is shown in your account and in every renewal reminder email.
Cancelling stops all future charges immediately.
Your subscription stays active until the end of the period you have already paid for, and any product already paid for will still be delivered.
There is no cancellation fee, no minimum number of orders, and no penalty of any kind.

4. Renewal reminders

We email you before each renewal charge so that nothing arrives unexpectedly. The reminder tells you what is coming, when you will be charged, how much, and gives you a one-click route to skip, pause, change or cancel.

If you are not receiving these reminders, check your spam folder and contact support@onyguard.com — reminder emails are not marketing and you cannot be unsubscribed from them while a subscription is active.

5. Orders that have already been processed

Once a subscription order has been charged and sent to our warehouse, it cannot be cancelled or recalled. It will be delivered.

You can still return it under our Return & Refund Policy, including under our 90-day money-back guarantee.

If you cancel within a few minutes of a renewal charge, contact us immediately at support@onyguard.com — if the order has not yet reached fulfilment we will do our best to stop it, but we cannot promise it.

6. Price and plan changes

Subscription pricing is discounted against the one-time price, and that discount holds for as long as the subscription stays active.
We will give you at least 7 days' notice by email before any change to your subscription price, interval or contents takes effect. You can cancel before the change applies.
If you cancel and later resubscribe, the price and terms available at that time will apply. We cannot guarantee that a previous promotional rate will still be available.

7. Failed payments

If a renewal payment is declined:

we will email you and retry the payment a limited number of times over a short period;
no product is dispatched until payment succeeds; and
if payment still cannot be taken, the subscription is paused or cancelled and you are not charged.

Updating your card in your account or through the Manage Subscription link resolves this immediately.

8. Refunds on subscription orders

Refunds are calculated on the discounted subscription price you actually paid, not the one-time price.
Cancelling a subscription is not the same as requesting a refund. Cancelling stops future charges; a refund for an order you have already received is handled under our Return & Refund Policy.
Our 90-day money-back guarantee applies to subscription orders in the same way it applies to one-time orders.

9. Cancelling a one-time order

If you want to cancel a one-time order after placing it, contact us within 20 minutes at support@onyguard.com with your order number. We will try to stop it before it reaches fulfilment.

Once an order has entered processing or shipping we cannot cancel it — but you can refuse delivery or return it once it arrives. See our Return & Refund Policy and Shipping Policy.

10. Cancellation by us

We may cancel or decline a subscription at any time, with notice and a refund of anything paid for product not yet sent, where:

payment cannot be taken;
the product is discontinued or unavailable;
we reasonably believe the account is being used for unauthorised resale, promotion abuse or fraud; or
you breach our Terms of Service.

11. Your rights under local law

Nothing in this Policy limits any right you have under the consumer protection law of your own country, state or province, and where any part of this Policy conflicts with such a right, that right prevails.

United States

Several states, including California, have automatic renewal laws requiring clear disclosure of recurring terms before purchase, affirmative consent to those terms, advance notice of changes, and a straightforward online cancellation route. This Policy is written to meet those requirements. If you are a California resident and believe you were charged for a subscription you did not knowingly agree to, contact support@onyguard.com and we will investigate and refund where appropriate.

Canada

Distance sales and automatic renewal contracts are governed by federal and provincial consumer protection legislation, including Quebec's Consumer Protection Act. Nothing in this Policy limits those rights.

Australia

Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. Nothing in this Policy limits your right to a repair, replacement or refund where those guarantees are not met.

European Union and United Kingdom

Where we sell to you in the European Union or the United Kingdom as a consumer, you have a statutory right to withdraw from the contract within 14 days of receiving the goods, without giving a reason, in addition to anything in this Policy.

12. Changes to this Policy

We may update this Policy. The version published at the time of your most recent charge governs that charge. Where a change materially affects your subscription, we will notify you in advance as described in Section 6.

13. Contact

Questions about a subscription, or trouble cancelling one? Tell us and we will sort it out.
