Privacy Policy

Last updated: 21 October 2026

DEL Illumination Co., Ltd. (“DEL”, “we”, “us” or “our”) explains in this Privacy Policy how we collect and use personal data through our website, business enquiries and related communications.

For privacy enquiries or requests, contact [email protected].

1. Information We Collect

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

• Contact information: your name, business email address, telephone number, company, job title and country.
• Enquiry and project information: product interests, project requirements, delivery details, documents and messages you provide.
• Business records: quotations, orders, correspondence and support requests.
• Website information: device and browser details, page visits, referring sources, interactions, cookie identifiers and server log information.
• Marketing preferences: subscription choices, consent records and unsubscribe requests.

Please avoid submitting unnecessary sensitive personal information or personal data belonging to others without appropriate permission.

2. How We Use Information

We use personal data, as applicable, to:

• Respond to enquiries and prepare product quotations or technical proposals.
• Manage orders, project communications, warranty enquiries and support.
• Operate, secure and improve our website.
• Understand website usage through Google Analytics.
• Measure advertising performance and, where enabled and permitted, support remarketing or personalised advertising.
• Send relevant product updates and marketing emails where permitted.
• Maintain business records and meet legal obligations.

3. Legal Bases for Processing

Where applicable data protection law requires a legal basis, we rely on:

• Contractual necessity: to take requested steps before entering a contract or to perform a contract with you.
• Legitimate interests: to manage business relationships, respond to business enquiries, protect our systems and improve our services, where these interests do not override your rights.
• Consent: for optional tracking, advertising or marketing activities where consent is required.
• Legal obligations: where processing is necessary to comply with applicable law.

Where you contact us on behalf of a business, processing your business contact details will generally relate to our legitimate interests in communicating with that business.

4. Cookies, Analytics and Advertising

Our website uses cookies and similar technologies for essential website functions, analytics and advertising.

Google Analytics helps us understand how visitors find and use our website. Advertising technologies may measure conversions and, depending on enabled features and your choices, help show relevant advertisements on other websites.

These technologies may process browser or device information, online identifiers and website interactions. Advertising providers may combine information with data they hold under their own privacy policies.

Where required by law, we seek consent before enabling non-essential analytics or advertising technologies. You can accept or reject optional categories and change your choices through the website’s cookie preference controls.

Browser settings can also restrict cookies, although blocking essential cookies may affect website functionality.

More information is available in Google’s explanation of data use on partner websites and Google’s Privacy Policy.

5. Marketing Emails

We may send product updates, technical information and other business marketing communications where you have consented or where applicable law otherwise permits.

You can unsubscribe using the link in a marketing email or by contacting [email protected].

Unsubscribing from marketing does not stop necessary communications about an enquiry, order, warranty claim or service request. We may retain limited information to ensure that your unsubscribe preference is respected.

Consent to advertising cookies does not, by itself, subscribe you to marketing emails.

6. Who Receives Information

Where necessary for the purposes described above, information may be shared with:

• Authorised DEL personnel and relevant business operations.
• Providers of website hosting, email, business systems and technical support.
• Analytics and advertising providers, including Google.
• Logistics providers and professional advisers involved in an order or service.
• Public authorities where disclosure is legally required.

Service providers acting on our behalf are subject to appropriate contractual obligations. Some analytics and advertising providers may also process information for their own purposes, as explained in their policies.

7. International Data Transfers

Our business operates across China, Germany and other international markets. Personal data may therefore be accessed or processed outside your country.

Where applicable law requires safeguards for international transfers, we use an appropriate transfer mechanism, such as an adequacy decision or approved contractual clauses, together with additional measures where necessary.

You may contact us for information about safeguards applicable to your personal data.

8. Data Retention

We retain personal data for as long as reasonably necessary for the purpose for which it was collected.

Retention depends on the nature of the information, the duration of the business relationship, warranty and support requirements, legal recordkeeping obligations and the need to establish or defend legal claims.

Analytics and advertising data retention depends on the relevant service settings and cookie durations. Consent and unsubscribe records may be retained to demonstrate compliance and honour your choices.

You may contact us for further details about retention periods relevant to your information.

9. Information Security

We use appropriate technical and organisational measures designed to protect personal data against unauthorised access, loss, misuse or disclosure.

No website, storage system or method of transmission is completely secure. Please contact us if you believe information shared with DEL has been compromised.

10. Your Rights

Depending on your location and applicable law, you may have the right to:

• Request access to your personal data.
• Correct inaccurate or incomplete information.
• Request deletion or restriction of processing.
• Object to processing, including direct marketing.
• Receive certain information in a portable format.
• Withdraw consent without affecting processing that occurred before withdrawal.
• Lodge a complaint with a competent data protection authority.

To submit a request, email [email protected]. We may request proportionate information to verify your identity and will respond within the period required by applicable law.

11. Third-Party Websites

Links to third-party websites are provided for convenience. Their privacy practices are governed by their own policies.

12. Children’s Privacy

Our website is intended for business and professional audiences. We do not knowingly collect personal data from children. If you believe a child has provided personal data, please contact us.

13. Changes to This Policy

We may update this policy when our website, services or data practices change. The latest version will appear on this page with an updated date. Where required, we will provide additional notice or request consent.
