Terms of Service

Last updated: July 28, 2026

1. About Us

This website and online store are operated by:

César Merino Daudén, trading as Hydra Runner
Avenida Monestir de Poblet 7
Aldaia, Valencia, Spain
Email: myhydrarunner@gmail.com

Throughout these Terms, “Hydra Runner”, “we”, “us” and “our” refer to César Merino Daudén.

Our store is hosted by Shopify, which provides the ecommerce platform that allows us to offer and sell our products.

These Terms of Service govern your access to and use of our website, store, content, products and related services.

By accessing our website or placing an order, you agree to these Terms, our Privacy Policy, Return and Refund Policy and Shipping Policy. If you do not agree, you must not use the website or place an order.

Nothing in these Terms limits any mandatory consumer rights that apply under the laws of your country or region.

2. Eligibility and Website Use

You must be at least 18 years old or have the permission and supervision of a parent or legal guardian to use this website or place an order.

You agree to provide accurate, complete and current information when placing an order or creating an account.

You are responsible for keeping your account credentials secure and for activity carried out through your account.

You may use the website only for lawful, personal and non-commercial purposes.

3. Products

We make reasonable efforts to display product descriptions, dimensions, features, colours and images accurately.

However, colours and appearance may vary depending on your screen, device settings, lighting and manufacturing variations.

Minor differences that do not materially affect the product’s function or overall appearance will not necessarily constitute a defect. This does not limit your rights where a product is defective, unsafe, incorrect or materially different from its description.

Product descriptions, availability and prices may be updated or corrected at any time. Changes will not affect an order already accepted, except where necessary to correct an obvious error and permitted by law.

Our products are intended for their stated recreational and sporting purposes. Customers must follow all product instructions, warnings and reasonable safety precautions.

A hydration vest does not replace appropriate preparation, professional advice, weather assessment, navigation equipment or emergency supplies for running, hiking or outdoor activities.

4. Orders and Contract Formation

When you place an order, you are making an offer to purchase the selected products.

After ordering, you will normally receive an automatic email confirming that we received your order. This acknowledgement does not necessarily mean that the order has been accepted.

A binding sales contract is formed when we confirm that the order has been accepted or dispatched, depending on the confirmation sent to you.

We may refuse or cancel an order before acceptance where reasonably necessary, including because:

• The product is unavailable;

• Payment cannot be authorised;

• The delivery address cannot be serviced;

• An obvious pricing or description error has occurred;

• We reasonably suspect fraud, misuse or unauthorised resale; or

• We are legally prohibited from completing the transaction.

If payment has already been taken for an order we cancel, we will refund the amount paid.

Please review your order carefully before submitting it. Contact us promptly if you need to request a cancellation or correction. We cannot guarantee changes after processing or dispatch has started.

5. Prices, Taxes and Payment

The price charged will be the price displayed at checkout when you place your order, subject to the correction of obvious errors.

Prices and promotions may change without notice, but changes will not normally affect orders already accepted.

Shipping costs and any applicable taxes will be shown at checkout or otherwise disclosed before the order is completed.

For international orders, customs duties, import taxes or brokerage charges may apply. Responsibility for these charges will be disclosed at checkout or in our Shipping Policy where applicable.

You confirm that you are authorised to use the payment method provided and that the payment information is accurate.

Payments may be processed by Shopify Payments or another third-party payment provider. We do not directly store full payment-card details when those details are processed by an authorised payment provider.

6. Shipping and Delivery

Available destinations, estimated delivery times and shipping charges are described at checkout or in our Shipping Policy.

Delivery dates are estimates unless we expressly agree to a guaranteed date.

We are responsible for fulfilling the order in accordance with applicable consumer law. Nothing in these Terms transfers the risk of loss to a consumer earlier than permitted by mandatory law.

We are not responsible for delays caused by events genuinely outside our reasonable control, including severe weather, customs disruption, transport interruption, strikes, natural disasters or government action.

If a delay is substantial, you may have the right to cancel the order under applicable law.

You are responsible for providing a complete and accurate delivery address. Contact us immediately if you discover an error.

7. Returns, Cancellations and Refunds

Returns, voluntary cancellations and refunds are governed by our Return and Refund Policy.

Hydra Runner provides a voluntary 90-day return period, subject to the conditions stated in that policy.

This commercial return period is additional to any mandatory cancellation, conformity, warranty or consumer rights that apply in your country.

Eligible consumers in the European Union and European Economic Area generally have a statutory right to withdraw from qualifying online purchases within 14 days after delivery, subject to legal exceptions.

Products that are defective, damaged, unsafe, incorrect or materially different from their description will be handled in accordance with applicable consumer law.

8. Product Safety and Responsible Use

You are responsible for selecting a product suitable for your intended activity, body size, carrying requirements and environmental conditions.

Before each use, inspect the vest, straps, fasteners, pockets, hydration components and accessories for wear, damage or improper adjustment.

Do not continue using a product that appears damaged, unsafe or unsuitable.

Hydration needs vary by person, climate, distance, intensity and medical circumstances. Product capacity or use should not be treated as medical or professional hydration advice.

Hydra Runner is not responsible for harm caused by misuse, improper adjustment, failure to follow instructions, unauthorised modification or use of the product for an unsuitable purpose, except where liability cannot legally be excluded.

9. Accounts and Customer Information

You may be able to create an account or check out as a guest.

You must not impersonate another person, use false information or use another person’s payment method without authorisation.

We may suspend or close an account where we reasonably believe it is being used unlawfully, fraudulently or in serious violation of these Terms.

Any processing of personal information is governed by our Privacy Policy.

10. Intellectual Property

Unless otherwise stated, the website and its original content—including the Hydra Runner name, branding, text, graphics, photographs, videos, page design and product presentation—are owned by or licensed to Hydra Runner.

You may access and use the website for personal shopping purposes.

You must not, without prior written permission:

• Copy, reproduce or commercially exploit substantial parts of the website;

• Use our branding in a misleading manner;

• Remove copyright or ownership notices;

• Present yourself as affiliated with or authorised by Hydra Runner; or

• Use website content to create a competing commercial service.

Third-party trademarks, images and materials remain the property of their respective owners.

11. Reviews and Customer Content

You may submit reviews, photographs, feedback or other content where this functionality is available.

Content submitted must be truthful, based on genuine experience and must not be unlawful, misleading, defamatory, abusive, discriminatory, obscene or infringe another person’s rights.

You must disclose any discount, free product, payment or other incentive received in exchange for submitting a review.

You retain ownership of your content but grant Hydra Runner a non-exclusive, worldwide, royalty-free licence to store, reproduce, display, format and use it for operating and promoting the store.

You may ask us to stop using content that identifies you, subject to our legal obligations and any rights already granted to third parties.

We may remove content that violates these Terms, applicable law or our review standards. We will not edit a genuine review in a way that materially changes its meaning.

12. Prohibited Activities

You must not use the website to:

• Break any applicable law;

• Commit or facilitate fraud;

• Submit false orders or payment information;

• Introduce viruses, malware or harmful code;

• Interfere with the website’s security or operation;

• Attempt to access restricted systems or information;

• Collect personal information about other users without permission;

• Send spam or unauthorised advertising;

• Infringe intellectual-property, privacy or other legal rights;

• Scrape or extract substantial website data for commercial purposes without permission; or

• Use automated systems in a manner that places an unreasonable burden on the website.

We may restrict access where reasonably necessary to protect customers, the website, our business or third parties.

13. Third-Party Services and Links

Our website may include services, applications, payment systems or links operated by third parties.

Those services may be subject to their own terms and privacy policies. We are not responsible for independent third-party websites or services that we do not control.

The presence of a link does not necessarily mean that we endorse the third party.

This section does not exclude responsibility that applicable law places on Hydra Runner for providers used to fulfil our obligations to customers.

14. Shopify

Our store is hosted on Shopify.

Products purchased through the store are sold by Hydra Runner, not by Shopify. Hydra Runner is responsible for the sale, product information, fulfilment, customer service, returns and legal obligations connected with the purchase.

Shopify may process information and provide technical, payment or ecommerce infrastructure in accordance with its own applicable terms and privacy documentation.

Nothing in these Terms creates a sales contract between the customer and Shopify.

15. Website Availability and Errors

We aim to keep the website available and accurate, but we do not guarantee that it will always be uninterrupted, secure or free from technical errors.

We may temporarily suspend access for maintenance, security, updates or circumstances outside our reasonable control.

We may correct typographical errors, inaccurate descriptions, availability information or obvious pricing mistakes.

If an error materially affects an order already placed, we will contact you and offer an appropriate correction, substitute where agreed, or cancellation and refund.

16. Legal Guarantees

Products are supplied with all guarantees and conformity rights required by applicable law.

Where EU or Spanish consumer law applies, customers may be entitled to remedies if goods are defective, do not match their description, are not fit for their normal purpose or otherwise fail to conform to the contract.

Depending on applicable law and the circumstances, remedies may include repair, replacement, price reduction or refund.

Any manufacturer’s or commercial warranty is additional to statutory rights and does not replace or reduce them.

17. Limitation of Liability

Nothing in these Terms excludes or limits liability where doing so would be unlawful, including liability for:

• Death or personal injury caused by negligence;

• Fraud or fraudulent misrepresentation;

• Deliberate misconduct;

• Defective products where liability is imposed by law;

• Breach of mandatory consumer rights; or

• Any other liability that cannot legally be excluded.

Subject to those protections, Hydra Runner will not be responsible for losses that were not reasonably foreseeable when the contract was formed or that result from circumstances outside our reasonable control.

Where you purchase as a consumer, we are responsible for foreseeable loss or damage caused by our breach of contract or failure to use reasonable care.

We are not responsible for business losses when products are purchased for personal or household use, including lost profit, lost revenue or business interruption.

18. Indemnity for Unlawful Use

Where permitted by law, you are responsible for losses reasonably incurred by Hydra Runner as a direct result of your unlawful use of the website, fraud, infringement of third-party rights or serious breach of these Terms.

This provision does not apply to ordinary consumer complaints, legitimate returns, chargebacks made in good faith or the exercise of statutory rights.

19. Events Outside Our Control

Neither party will be responsible for delay or failure caused by an event outside that party’s reasonable control.

We will take reasonable steps to reduce the effect of such an event and resume performance when reasonably possible.

This section does not remove any right a consumer may have to cancel an order because of a substantial delay or failure to deliver.

20. Suspension and Termination

You may stop using the website at any time.

We may suspend or terminate access where you seriously or repeatedly violate these Terms, use the website unlawfully or create a genuine security or fraud risk.

Termination does not affect orders already accepted, amounts already due, statutory rights or provisions that are intended to continue after termination.

21. Governing Law and Disputes

These Terms and any contract with Hydra Runner are governed by Spanish law.

If you are a consumer residing outside Spain, this choice of law does not deprive you of mandatory consumer protections available under the law of your habitual country of residence.

We encourage customers to contact us first at myhydrarunner@gmail.com so we can try to resolve any problem directly.

Where legally permitted, disputes will be submitted to the competent courts of Spain.

However, consumers may bring proceedings before any court available to them under mandatory consumer jurisdiction rules. Nothing in these Terms requires a consumer to waive a court, remedy or protection that cannot lawfully be waived.

22. Severability

If any provision of these Terms is found to be unlawful, invalid or unenforceable, that provision will apply to the greatest extent legally permitted or be removed to the minimum extent necessary.

The remaining provisions will continue in effect.

23. No Waiver

A delay or failure by Hydra Runner to enforce a provision does not waive the right to enforce it later.

24. Changes to These Terms

We may update these Terms to reflect changes to our services, business practices or legal obligations.

The updated version will be published on this page with a revised “Last updated” date.

Material changes will not retroactively reduce rights attached to orders already accepted, unless required by law or expressly agreed with the customer.

25. Entire Agreement

These Terms, together with our Privacy Policy, Return and Refund Policy, Shipping Policy and any conditions displayed during checkout, form the agreement governing use of the store and purchases made through it.

If a specific promotion or product condition conflicts with these general Terms, the more specific condition will apply, provided it complies with mandatory law.
