Privacy Policy

HHO™ — Hydrogen Health Optimization™ is committed to protecting the personal information of every visitor and customer. This policy explains what we collect, why we collect it, how we use it, and the rights you have over your data.

Last updated · 6 June 2026

1. Who we are

HHO™ is operated by YBG Group International Pty Ltd, a company registered in Australia (ABN 22 636 934 999, ACN 636 934 999). References to "HHO™", "we", "us" and "our" in this policy refer to YBG Group International Pty Ltd.

Postal address: PO Box 139, Berowra Heights NSW 2082, Australia. For all privacy enquiries, contact us at admin@hho.company.

2. Personal information we collect

We collect personal information in the following circumstances:

  • Contact forms & enquiries: name, email address, message content.
  • Newsletter & briefings: email address and country.
  • Orders: billing name, shipping address, contact telephone, email address, the products purchased and any delivery notes you provide.
  • Payment processing: payment is processed by Stripe. We do not see or store full card numbers, CVV codes, or banking credentials.
  • Website usage: IP address, browser type, device type, referrer, pages visited and approximate location, recorded automatically in server logs and via strictly necessary cookies.
  • Customer correspondence: any communications you send to us by email or via the website.

3. How we use your information

We use personal information to:

  • process orders, take payment, and fulfil international shipping including customs documentation;
  • respond to enquiries, briefing requests and customer support;
  • send order, shipping, warranty and service-related communications;
  • send newsletters and product information only where you have opted in;
  • monitor and improve the performance, security and usability of the website;
  • meet our legal, tax, accounting and consumer-law obligations.

4. Cookies & analytics

HHO.company currently uses only a small number of strictly necessary cookies required to operate the site — for example, to remember your selected country and currency. No third-party advertising or tracking cookies are set.

We do not currently operate a third-party analytics platform (such as Google Analytics, Plausible or similar). Basic, non-identifying request information (such as IP address, user agent and requested URL) is recorded in standard server logs for security, fraud prevention and aggregate traffic measurement, and is retained for a limited period.

You can disable or delete cookies in your browser settings. Disabling strictly necessary cookies may affect site functionality (for example, your country and currency preference will not be remembered). If we introduce non-essential cookies or a third-party analytics platform in the future, we will update this policy and, where required by law, request your consent before any such cookies are loaded.

5. Payment processing — Stripe

Payments on HHO.company are processed by Stripe, Inc. and its regional affiliates. When you make a purchase, payment details are submitted directly to Stripe via Stripe's secure embedded checkout. We receive a confirmation of the transaction, the amount, the currency, the country and a Stripe customer reference — we do not receive card numbers or CVV codes.

Stripe is independently certified to PCI DSS Level 1, the highest level of payment-card data security. Stripe's own privacy practices are published at stripe.com/privacy.

6. International visitors & data transfers

HHO™ sells internationally. By using the site or placing an order, your information may be transferred to and processed in Australia (our base of operations), the United States (Stripe payment processing), the European Union and the United Kingdom (logistics and customs partners), and any country to which a shipment is dispatched.

We rely on appropriate safeguards including standard contractual clauses, equivalent-protection provisions, and contractual confidentiality with all sub-processors.

7. GDPR & UK GDPR rights

If you are located in the European Economic Area, the United Kingdom or Switzerland, you have the following rights under the EU General Data Protection Regulation and the UK GDPR:

  • right to access the personal information we hold about you;
  • right to rectification of inaccurate information;
  • right to erasure ("right to be forgotten") subject to legal retention obligations;
  • right to restrict or object to processing;
  • right to data portability in a structured, machine-readable format;
  • right to withdraw consent at any time where consent is the legal basis;
  • right to lodge a complaint with your local supervisory authority.

Our lawful bases for processing are: performance of a contract (orders), legitimate interests (security, fraud prevention, product improvement), consent (marketing communications) and legal obligation (tax, customs, consumer law).

To exercise any right, email admin@hho.company. We will respond within 30 days.

8. Data retention

We retain personal information only as long as needed for the purpose for which it was collected:

  • Order & invoice records: 7 years, to meet Australian, EU and UK tax-record requirements.
  • Warranty records: the warranty period plus 2 years.
  • Customer support correspondence: 3 years from the last contact.
  • Newsletter list: until you unsubscribe.
  • Server logs: up to 90 days, then deleted or anonymised.

9. Security

We use TLS encryption in transit, restricted-access cloud hosting, encrypted database storage and role-based access controls. No system is perfectly secure; in the unlikely event of a breach affecting your personal information, we will notify you and the relevant supervisory authority in accordance with applicable law.

10. Children

HHO™ products are wellness-technology products intended for adult use. The website is not directed to children under 16 and we do not knowingly collect personal information from children.

11. Changes to this policy

We may update this policy from time to time. The "last updated" date at the top of this page reflects the current version. Material changes will be announced on the homepage or by email to affected customers.
