Privacy policy

Cyrex Ltd, trading as ElectraStim, respects your privacy. This policy explains how we collect, use, share and protect personal information when you visit our websites, place an order, subscribe to marketing or contact us.

It applies to the ElectraStim websites operated by Cyrex Ltd, including www.electrastim.com, us.electrastim.com and eu.electrastim.com. Your rights may vary according to the country in which you live.

1. Who we are

Cyrex Ltd (trading as ElectraStim) is responsible for deciding how personal information is used for its own business activities. You can contact us at info@electrastim.com or by post at Cyrex Ltd, Unit 36, Hoddesdon Industrial Centre, Pindar Road, Hoddesdon, Hertfordshire, EN11 0FF, United Kingdom.

2. Information we collect

Depending on how you interact with us, we may collect:

• Contact and account details, including your name, email address, telephone number, billing and delivery addresses.

• Order and payment details, including items purchased, order history, delivery information, payment status and transaction references. Full payment card details are handled by payment providers rather than being made available to our customer service team.

• Customer service information, including enquiries, warranty claims, returns, complaints, correspondence and any documents or images you choose to send us.

• Website and device information, such as IP address, browser, device information, pages viewed, products added to your basket and cookie identifiers.

• Marketing preferences and interactions, including newsletter subscriptions, opt-outs and engagement with our communications.

• Reviews or other information that you choose to submit through our website or connected services.

We receive most information directly from you, but may also receive relevant information from payment providers, delivery partners and other services involved in your order.

3. How and why we use your information

We use personal information for the following purposes and legal reasons, where applicable:

• To process payments, fulfil orders, arrange delivery and provide returns or warranty support — to perform our contract with you.

• To answer enquiries, investigate complaints, maintain records and improve our products and customer service — for our legitimate business interests and, where applicable, to meet legal duties.

• To prevent fraud, maintain website security and protect our business and customers — for legitimate interests and legal compliance.

• To maintain accounting, tax and other legally required records — to comply with legal obligations.

• To send marketing emails, product news and eligible basket reminders — with your consent where required, or under a permitted existing-customer marketing exception where applicable.

• To understand website performance and improve the shopping experience — for legitimate interests, subject to consent requirements for non-essential cookies or tracking.

Where we rely on consent, you can withdraw it at any time. Doing so does not affect processing carried out lawfully before withdrawal.

4. Shopify and other service providers

Our online stores are hosted by Shopify. Shopify processes personal information to operate our websites, support checkout and orders, and provide related services. Depending on the Shopify features enabled, Shopify may also use information about interactions with our store and with other merchants for enhanced shopping experiences, analytics and advertising. Please read Shopify’s Consumer Privacy Policy and privacy choices:

Shopify Consumer Privacy Policy | Shopify Privacy Portal

We may also share relevant information with providers that help us operate our business, including:

• Payment services such as Shopify Payments, PayPal, Klarna and Clearpay, depending on the payment methods offered at checkout.

• Delivery providers such as Royal Mail, DHL and other carriers used to fulfil orders.

• Klaviyo for email marketing and related customer communications.

• Google services, including Google Analytics and Google Ads, for website measurement and advertising where permitted.

• Judge.me for product reviews and Affiliately for affiliate referral tracking, where those services are used.

• Professional advisers, IT and security providers, or public authorities where reasonably necessary or legally required.

These providers may process information on our behalf or, in some circumstances, for their own purposes under their own privacy notices. We share information only where it is relevant to the service or lawful purpose involved. Some payment providers may conduct automated eligibility or fraud checks under their own privacy notices, which explain the applicable rights and options.

5. Cookies and website tracking

We use cookies and similar technologies to operate our websites, remember basket contents, understand visitor activity and, where enabled, personalise content or measure advertising. Some cookies are essential for the website to function; others, such as certain analytics and advertising cookies, are non-essential.

Where required by law, we ask for your consent before using non-essential cookies or tracking technologies. You can manage or withdraw your choices through the cookie controls made available on our websites and through your browser settings. Rejecting non-essential cookies should not prevent you from making a purchase.

6. Email marketing

We use Klaviyo to send newsletters, product information and relevant follow-up messages. We send marketing emails when you have opted in or, where the law permits, to existing customers about similar products if they were given a clear opportunity to opt out when their details were collected.

You can unsubscribe from marketing at any time using the link in our emails or by contacting info@electrastim.com. Unsubscribing will not stop essential messages about orders, deliveries, customer service or safety information.

7. How long we keep information

We keep personal information only as long as necessary for the purposes described in this policy, including fulfilling orders, supporting warranties, complying with accounting or tax obligations, resolving disputes and protecting legal rights. Retention periods depend on the type of information and applicable legal requirements.

We keep records of complaints and their outcomes to resolve issues and identify improvements, subject to appropriate retention periods. If you unsubscribe from marketing, we may retain a limited record of that choice to ensure it is respected.

8. Storage, security and international transfers

We take reasonable technical and organisational steps to protect personal information and restrict access to people and providers who need it for legitimate business purposes. Payments are processed using secure payment services.

Our service providers may store or access personal information outside the UK, including in countries where they operate. Where data protection law requires safeguards for international transfers, we use applicable legal mechanisms, such as recognised adequacy arrangements or contractual safeguards. Contact us if you would like further information about relevant transfer protections.

9. Your privacy rights

Depending on applicable law, you may have the right to request access to your personal information; ask us to correct or delete it; restrict how it is used; receive certain information in a portable format; or object to certain processing.

You can object to the use of your personal information for direct marketing at any time. If we rely on consent, you may withdraw it. Some rights are subject to legal exceptions, including where we must retain records for legal purposes.

To make a request, email info@electrastim.com. We may ask you to confirm your identity before responding.

10. Complaints about personal information

If you have concerns about how we handle your personal information, please contact us so we can investigate. You can find out how to raise a complaint and how we handle it in our Complaints Policy.

You also have the right to complain to the Information Commissioner’s Office (ICO), the UK data protection regulator, or to another relevant supervisory authority where applicable.

11. Other websites and updates

Our websites may link to other services that have their own privacy notices. We are not responsible for how independent websites handle personal information.

We may update this policy to reflect changes in the law, technology or our business practices. The latest version will be published here with an updated date.
