Nanjing DUNEN Electric Co., Ltd. (“DUNEN”, “we”, “us” or “our”) operates https://dn-elec.com (the “Website”). This Privacy Policy explains how we collect, use and protect personal data when you visit the Website. By using the Website you agree to the practices described here.

1. Who we are

2. What data we collect

The Website is a corporate and product-information site. We collect only the data needed to operate and measure it:

  • Analytics data: pages visited, approximate (non-exact) location from IP, device and browser type, language, referring source, and approximate visit time.
  • Technical data: shortened/anonymized IP address and standard server log data.
  • Inquiry data: if you email or contact us, the information you choose to send us (such as your name, company and email address).

We do not operate an online shop and we do not request payment data on this Website.

3. Google Analytics

We use Google Analytics 4 (provided by Google LLC and Google Ireland Limited) to understand how the Website is used. Google Analytics sets cookies and may transfer collected data to servers in the United States. Google only receives data after you accept statistics cookies in our consent banner — no Google Analytics request or cookie is set before you consent.

You can refuse or withdraw this consent at any time via the banner’s “Deny” option or the “Manage options” link. You can also block analytics by installing the official Google Analytics opt-out browser add-on. Google’s use of this data is governed by Google’s privacy policy: https://policies.google.com/privacy.

4. Cookies and similar technologies

We use a consent banner (Complianz) to ask for your consent before placing non-essential cookies. Cookies fall into the following categories:

  • Functional / necessary: cookies required for the site to work and to remember your consent choice. These are always set.
  • Statistics: Google Analytics cookies, set only if you accept them.
  • Preferences / Marketing: used only if you consent; we do not run advertising trackers on this Website.

You can control or delete cookies through your browser settings. Blocking cookies may affect some functions of the Website.

5. Legal bases (EU / UK GDPR)

Where the UK or EU General Data Protection Regulation applies, we process analytics data on the basis of your consent (Article 6(1)(a) GDPR), and necessary/technical data on the basis of our legitimate interest in a secure, working website (Article 6(1)(f)). You may withdraw consent at any time without affecting the lawfulness of processing before withdrawal.

6. Your data protection rights

If you are located in the European Union, the United Kingdom or other regions with data-protection laws, you have the right to:

  • access the personal data we hold about you;
  • have inaccurate data corrected;
  • request deletion of your data (“right to be forgotten”);
  • restrict or object to certain processing;
  • receive a portable copy of your data;
  • withdraw consent at any time; and
  • lodge a complaint with your local data protection authority.

To exercise any of these rights, email sales@dn-elec.com.

7. California privacy rights (CCPA / CPRA)

If you are a California resident, you have the right to know what personal information we collect, to request deletion, and not to be discriminated against for exercising these rights. We do not sell personal information in exchange for money. Analytics data may be shared with Google for measurement purposes; you can prevent this by choosing “Deny” in the consent banner. To submit a request, email sales@dn-elec.com.

8. Data retention

We keep analytics data only as long as needed for reporting (Google Analytics retains data according to the configured retention period, currently 14 months for user-level data). Business inquiry records are kept while relevant to our relationship.

9. Data security and international transfers

We use reasonable technical and organisational measures to protect your data. When analytics data is shared with Google, it may be processed outside your country (including the United States); appropriate safeguards apply under Google’s data-processing terms.

10. Children

The Website is intended for business customers and is not directed at children. We do not knowingly collect data from children.

11. Changes to this policy

We may update this Privacy Policy from time to time. The latest version will always be available on this page with an updated date.
