General Terms and Conditions of Sale and Use

Last updated: September 14, 2026

Please read these terms before using zerical.com or placing an order. By purchasing, you agree to be bound by them.

1. Identification of the Owner


Owner	Emrerdemnet LTD
Address	4 Raven Road, Unit 1C3-1244, London, United Kingdom, E18 1HB
Email	info@zerical.com
Website	zerical.com

Emrerdemnet LTD is established in the United Kingdom. By directing its offer to consumers residing in Spain, it applies Spanish and European consumer regulations, in particular Royal Legislative Decree 1/2007 (TRLGDCU) and Law 34/2002 (LSSI-CE).

2. Who Can Purchase

You must be over 18 years of age and have the legal capacity to enter into a contract. The store is intended for consumers purchasing for personal use, not for resale.

3. The Product

Zerical is a device for home use that is placed in the toilet cistern. By attracting and retaining the limescale present in the water, it helps reduce the formation of limescale stains in the bowl.

It must be used following the instructions included in the packaging. It is not intended for any use other than that described or for professional or industrial installations.

Photographs and videos are representative. There may be minor differences in tone or finish compared to the unit received.

4. Prices and Orders

Prices are shown in euros and include the applicable VAT. Shipping costs, if any, are indicated separately before confirming the order.

We may change prices at any time, but the price applicable to your order is the one that appeared when you confirmed it. A subsequent change does not affect you.

The contract is perfected when you receive our order confirmation via email. If, due to an obvious pricing error or lack of stock, we are unable to fulfill it, we will notify you and provide a full refund.

5. Right of Withdrawal

You have 14 calendar days from the receipt of the product to withdraw without justifying your decision and without penalty.

How to exercise it: notify us at info@zerical.com by means of an unequivocal statement or by using the form at the end of this document.

Product return: send it back within a maximum period of 14 calendar days from the date you notify us of your decision.

Return costs: the direct costs of the return are borne by you, in accordance with Article 108.1 of the TRLGDCU. We expressly state this here before purchase, as required by law.

Refund: we will refund all payments received, including standard delivery costs, within a maximum of 14 calendar days from your notification. We may withhold the refund until we receive the product or until you provide proof of return.

You are responsible for any diminished value resulting from handling other than what is necessary to establish the nature and functioning of the product.

6. Legal Warranty of Conformity

You are entitled to the 3-year legal warranty of conformity from delivery (Articles 114 and following of the TRLGDCU).

If the product is not in conformity, you may demand its repair or replacement and, if that is not appropriate, a price reduction or termination of the contract. During the first two years, it is presumed that the lack of conformity already existed at delivery, unless proven otherwise.

To file a claim, write to info@zerical.com, describing the problem and attaching photographs if possible.

Important: when the product is defective or non-conforming, all costs are borne by us, including return and reshipping costs. The previous rule regarding return costs applies only to withdrawals due to a change of mind.

7. Intellectual Property

The texts, photographs, videos, logos, designs, and other content on zerical.com are the property of Emrerdemnet LTD or its licensors, protected by national and international intellectual and industrial property regulations.

Their reproduction, distribution, public communication, or transformation is not permitted without written authorization. Access to the site does not grant any rights over them.

8. Use of the Site

You agree not to:

reverse engineer or attempt to obtain the source code;
introduce illicit, offensive, defamatory content, or content that violates third-party rights;
use automated systems that impair the operation of the site;
impersonate another person.

Non-compliance may lead to the suspension of access and corresponding legal action.

You must provide truthful data and keep your credentials confidential. If you detect unauthorized use of your account, notify us immediately.

9. Our Liability

We strive to ensure the site operates continuously, but we cannot guarantee the complete absence of technical interruptions or occasional unavailability.

Nothing in these terms limits or excludes your legal rights as a consumer, nor our liability for fraud, gross negligence, personal injury, or any case where the law does not permit exclusion.

10. Force Majeure

Neither party shall be liable for failure to comply caused by circumstances beyond their reasonable control—natural disasters, fires, armed conflicts, strikes, epidemics, supply interruptions, or widespread network failures. Obligations are suspended while the cause lasts. If it lasts more than 30 days, either party may terminate the contract with a full refund.

11. Modification of These Terms

We may modify them to adapt to legal or operational changes. The terms in force at the time of placing your order always apply to your order; subsequent changes do not have retroactive effect.

12. Partial Nullity

If any clause is declared void, the rest shall remain in force. The affected clause will be replaced by another that respects the original purpose within the limits permitted by law.

13. Data Protection

The processing of your data is governed by our Privacy Policy.

14. Claims, Applicable Law, and Jurisdiction

Claims: write to us at info@zerical.com. We respond as soon as possible and, in any case, resolve the matter within a maximum of one month.

Applicable law: these terms are governed by Spanish law. In any case, you retain the protection of the mandatory provisions of the country of your habitual residence (Article 6 of the Rome I Regulation).

Jurisdiction: as a consumer, you may sue before the courts of your place of residence and you can only be sued before the courts of your own place of residence (Articles 17 to 19 of Regulation (EU) 1215/2012).

Alternative resolution: you can turn to the Consumer Arbitration System or your local municipal consumer information office.
