By accessing or using the Hydrogen Vitality website (the "Website") or purchasing any product or service from us, you confirm that you have read, understood, and agree to be bound by these Terms & Conditions, together with our Privacy Policy and Refund & Cancellation Policy, which are incorporated herein by reference.
If you do not agree to these Terms & Conditions, you must immediately discontinue use of the Website and refrain from making any purchase.
2. Our Products and Services
Hydrogen Vitality operates a network of hydrogen-enriched water dispensing machines (the "Machines"). Access to the Machines is granted through a prepaid IC card system. IC Cards are issued free of charge at participating gyms and clinics — simply ask any staff member. The Card number is printed on the Card and is required to purchase credit online. We do not offer direct payment at the Machines.
2.1 Starter Card
Price: €6.00 (one-time purchase)
The Starter Card is a credit purchase that includes:
- Five (5) litres of hydrogen water credit, loaded to your Card immediately upon completion of your online purchase;
- Access to the six-week Hydrogen Vitality Protocol (see clause 2.5).
To get started: collect a free IC Card from any gym or clinic staff member, visit hydrogenvitality.ie, select the Starter Card, enter your Card number, and complete checkout. Credit is available on your Card immediately.
The Starter Card may only be purchased once per customer account.
2.2 Starter Kit

The Starter Kit includes:
- Five (5) litres of hydrogen water credit, loaded to your Card immediately upon completion of your online purchase;
- One (1) stainless steel water bottle (1 litre capacity), collected from your gym or clinic's information office upon presentation of your order confirmation;
- Access to the six-week Hydrogen Vitality Protocol (see clause 2.5).
To get started: collect a free IC Card from any gym or clinic staff member, visit hydrogenvitality.ie, select the Starter Kit, enter your Card number, and complete checkout. Credit is available on your Card immediately. Present your order confirmation at the gym information office to collect your bottle.
The Starter Kit may only be purchased once per customer account.
2.3 Monthly Subscription Plan
Price: €19.00 per month (recurring)
The Monthly Subscription Plan includes:
- Up to forty (40) litres of hydrogen water credit per billing cycle, loaded to your Card at the start of each month;
- One (1) stainless steel water bottle (1 litre capacity), collected from your gym or clinic's information office upon presentation of your order confirmation at the start of your subscription. The bottle is provided once and is not reissued each month;
- Access to the six-week Hydrogen Vitality Protocol (see clause 2.5).
To get started: collect a free IC Card from any gym or clinic staff member, visit hydrogenvitality.ie, select the Subscription Plan, enter your Card number, and complete checkout. Your first month's credit is loaded to your Card immediately. Present your order confirmation at the gym information office to collect your bottle.
Credit allocation and monthly reset: At the start of each billing cycle, your Card balance is reviewed and topped up so that your total available credit reaches forty (40) litres. Unused credit from the previous month is carried forward and the balance is replenished to bring the total to 40 litres. By way of example: if you have 20 litres remaining at the end of a billing cycle, 20 litres will be added at the start of the new cycle to restore your balance to 40 litres. Credit does not accumulate beyond the 40-litre monthly cap, regardless of how much was unused in any prior period.
Cancellation: You may cancel your Monthly Subscription Plan at any time. Cancellation takes effect at the end of your current billing cycle. You will retain full access to the Machines and your remaining credit for the remainder of the billing period in which you cancel. No further monthly charges will be applied after the current billing cycle ends. No refund is due for any portion of the current billing period already paid. Upon cancellation, you may keep the IC Card and stainless steel bottle. To cancel, please contact us at info@hydrogenvitality.ie or follow the cancellation process in your account settings.
2.4 Top-Up Credit
Top-Up Credit is additional prepaid credit purchased through the Website and loaded onto your existing Card immediately upon payment. Top-Up Credits are non-transferable and may only be used on the Card to which they are assigned.
2.5 Six-Week Hydrogen Vitality Protocol
All products include access to the six-week Hydrogen Vitality Protocol (the "Protocol"), a structured programme designed to help you monitor and track improvements in your wellbeing over a six-week period. Access details for the Protocol are provided at the time of purchase. The Protocol is provided for personal informational purposes only and does not constitute medical advice (see clause 9).

5. IC Card Terms

Monthly Subscription credit is subject to the 40-litre monthly cap described in clause 2.3.
5.4 Lost, Stolen, or Damaged Cards
If your Card is lost, stolen, or damaged, you must notify us as soon as possible at info@hydrogenvitality.ie. Upon notification and verification of your identity and account:
- We will deactivate the compromised Card to prevent unauthorised use.
- You may obtain a new free Card from any gym or clinic staff member.

We are not liable for any credit used on the Card prior to us receiving your notification of loss, theft, or damage.

6. Use of the Machines
6.1 Permitted Use
By using a Machine, you agree to:
- Use the Machine only as intended and in accordance with any instructions displayed on or near the Machine;
- Treat the Machine and its surroundings with care and respect;
- Not tamper with, damage, or attempt to interfere with the Machine or its components in any way.
6.2 Machine Availability
While we endeavour to ensure the Machines are operational at all times, we do not guarantee uninterrupted availability. Machines may be temporarily out of service for maintenance, technical reasons, or circumstances beyond our control. We shall not be liable for any loss or inconvenience arising from Machine unavailability.
6.3 Prohibited Conduct
You must not use any Machine or the Website in any manner that is unlawful, fraudulent, harmful, or disruptive. Any attempt to circumvent the Card payment system, manipulate the Machines, or use another person's Card without authorisation may result in immediate account termination and may be reported to the relevant authorities.
7. Right of Withdrawal (EU Consumers)
In accordance with the European Union Consumer Rights Directive (2011/83/EU) and the European Union (Consumer Information, Cancellation and Other Rights) Regulations 2013, as a consumer purchasing via our Website you ordinarily have the right to withdraw from a distance contract within 14 calendar days without giving any reason.
However, please note the following exceptions which apply to our products:
- Top-Up Credit: By completing your purchase of Top-Up Credit and entering your Card number at checkout, you expressly consent to the immediate loading of credit to your Card. The right of withdrawal is lost at the point of payment, as the digital service is fully performed immediately at your express request.
- Starter Card: By completing your Starter Card purchase and entering your Card number at checkout, you expressly consent to the immediate loading of credit to your Card. The right of withdrawal is lost at the point of payment, as the digital service is fully performed immediately at your express request.
- Starter Kit: Since credit is loaded to your Card immediately upon payment, the right of withdrawal in respect of the prepaid credit element is lost at the point of payment. The stainless steel bottle retains the standard 14-day right of withdrawal, provided it has not been used or filled. The bottle may not be returned once it has been used or filled, as it constitutes a hygiene item under Article 16(e) of the EU Consumer Rights Directive. To withdraw from the bottle element, notify us at info@hydrogenvitality.ie within 14 days and return the unused bottle to the gym information office.
- Monthly Subscription Plan: Since credit is loaded to your Card immediately upon payment, the right of withdrawal in respect of the credit element is lost at the point of payment. The stainless steel bottle retains the standard 14-day right of withdrawal, provided it has not been used or filled. For ongoing monthly charges after the initial period, your right to cancel is governed by clause 2.3 above, and no statutory right of withdrawal applies to subsequent recurring payments.
To exercise your right of withdrawal on any eligible item, you must notify us at info@hydrogenvitality.ie before the withdrawal period expires, clearly stating your intention to withdraw and your order details.
