1. Introduction
Changzhou Chuanglian Power Supply Technology Corporation ("Trelin", "Trelin Power", "we", "us", or "our") operates the website located at https://en.trelin.cn (the "Website"). We respect your privacy and commit to protecting your personal information ("Personal Information") in accordance with this Privacy Policy and applicable data protection laws, including, where relevant, the EU General Data Protection Regulation ("GDPR"), the UK GDPR and the Privacy and Electronic Communications Regulations ("PECR"), and the California Consumer Privacy Act as amended by the California Privacy Rights Act ("CCPA/CPRA").
This Policy explains what information we will collect when you visit the Website or submit inquiries, sample requests, or other communications to us, how we will use and share that information, and the rights available to you.
This Policy is published in both English and Chinese for convenience. In the event of any inconsistency between the two versions, the English version shall prevail for interpretation purposes, except where mandatory Chinese law requires the Chinese version to govern.

For the purposes of the GDPR, Trelin acts as the data controller of Personal Information collected through the Website.
Where required under Article 27 of the GDPR and/or the UK GDPR, Trelin will appoint a representative established in the EU and/or the UK. Once appointed, the representative's name and contact details will be published on this page and made available on request at privacy@cl-power.com.
3. What Personal Information We Collect
3.1 Information you provide directly and voluntarily
- Name, company name, job title

3.2 Information collected automatically

- Browser type, device type, operating system
- Pages visited, time spent, referral source, click paths
- Cookie and similar-technology identifiers (see Section 5)
3.3 Information from third parties
- Occasional third-party information, from authorized distributors/partners who refer an inquiry to us, or from trade-show/event lead forms, where you have consented to that referral.
We do not knowingly seek to collect any special category / sensitive personal data (e.g. health, biometric, religious, or political data) through the Website, and ask that you do not submit such data to us in any inquiry, sample request, or message field.
4. How We Use Your Personal Information and Legal Basis
Where the GDPR applies, we rely on the following legal bases under Article 6:
| Purpose | Legal basis (GDPR Art. 6) |
|---|---|
| Responding to inquiries, quotation requests, and sample requests | Performance of a contract / steps taken at your request prior to entering into a contract (Art. 6(1)(b)) |
| Sending requested product or technical information, catalogues, datasheets | Legitimate interest in providing the service you requested (Art. 6(1)(f)) |
| Marketing communications (newsletters, product updates, event invitations) | Consent (Art. 6(1)(a)) — you may withdraw at any time |
| Website analytics and performance improvement | Consent, for non-essential analytics cookies (Art. 6(1)(a)), or legitimate interest for essential functions (Art. 6(1)(f)) |
| Fraud prevention and website security | Legitimate interest (Art. 6(1)(f)) |
| Complying with legal obligations (e.g. export control, tax, accounting) | Legal obligation (Art. 6(1)(c)) |
5. Cookies and Similar Technologies
The Website uses cookies and similar technologies (such as pixels and local storage) in the following categories:
- Strictly Necessary Cookies — required for the Website to function (e.g. security, load balancing); cannot be switched off.
- Performance Cookies — help us understand how visitors use the Website (e.g. Google Analytics).
- Functional Cookies — remember choices you make (e.g. language).
- Targeting Cookies — used to measure or personalize marketing content, where applicable.
For visitors in the EU, UK, and EEA, non-essential cookies (Performance, Functional, and Targeting) will only be set with your prior, opt-in consent, obtained through a cookie consent banner that lets you accept all, reject all, or customize your choice by category before any non-essential cookie is activated. You can change your preferences at any time via the "Cookie Settings" link in the Website footer. Consent choices are recorded for 12 months, after which we will ask again.
For visitors in California under CCPA/CPRA protections, we will process opt-out requests related to targeted advertising and the "sale" or "sharing" of Personal Information in accordance with applicable law, and recognize and honor applicable Opt-out Preference Signals ("OOPS") where required by law.
6. How We Share Your Personal Information
We will not sell your Personal Information to any third party. We will only share, transfer, or disclose your Personal Information in the following circumstances:
- Internal group companies / affiliates, for order fulfilment or after-sales support.
- Authorized local distributors or agents, for localized sales follow-ups in your region, where appropriate to your enquiry, who are bound by contractual confidentiality obligations.
- Service providers acting on our behalf (e.g. IT hosting, CRM and email service providers, analytics providers), who are bound by contractual confidentiality obligations.
- Legal or regulatory authorities, where required by law or to establish, exercise, or defend legal claims.
We do not sell Personal Information for monetary gain. For CCPA purposes, we do not "share" Personal Information for cross-context behavioral advertising, except through Targeting cookies that you have separately, and affirmatively, consented to — which is a stricter standard than the CCPA/CPRA's default opt-out approach.
7. International Data Transfers
Trelin is headquartered in China, and the Website and associated systems may be hosted in China and/or other countries where our service providers operate. Personal Information you submit, as well as information collected via cookies and similar technologies (including through analytics or other third-party tools), may therefore be transferred to, stored, and processed in China and other jurisdictions whose data protection laws may differ from those of your home country.
Where required — for example, for transfers of Personal Information originating in the EU, UK, or EEA — we implement appropriate safeguards, such as Standard Contractual Clauses (SCCs), or rely on an applicable statutory derogation, and take reasonable steps to ensure a level of protection comparable to that required in your home jurisdiction.
8. Data Retention
- Inquiry, RFQ, and sample-request records: retained for 2 years from the date of last contact, for business, quotation-history, and warranty-support purposes, unless a longer period is required by law.
- Marketing consent records: retained until you withdraw consent, plus a reasonable period afterward as evidence of compliance.
- Cookie / analytics data: retained for the period configured in the relevant tool's settings, which we review periodically to ensure it is no longer than necessary for the purposes described in Section 5. Current retention settings are available on request at privacy@cl-power.com.
We delete or anonymize Personal Information once it is no longer needed for the purposes above, subject to any longer retention period required by law (e.g. accounting or tax records).
9. Your Rights
9.1 General Rights (including EU / UK / EEA Residents under GDPR)
- Access a copy of the Personal Information we hold about you.
- Correct inaccurate or incomplete Personal Information.
- Request erasure of your Personal Information ("right to be forgotten").
- Restrict or object to certain processing, including direct marketing.
- Request data portability, for data you provided to us under consent or contract.
- Withdraw consent at any time, without affecting the lawfulness of processing carried out before withdrawal.
- Lodge a complaint with your local data protection supervisory authority.
We do not carry out solely automated decision-making, including profiling, that produces legal effects concerning you or similarly significantly affects you.
9.2 California Residents (CCPA/CPRA)
If you are a California resident, you additionally have the right to:
- Know what Personal Information we have collected, used, disclosed, and (if applicable) sold or shared, and for what purposes.
- Delete Personal Information we hold about you, subject to certain exceptions.
- Correct inaccurate Personal Information.
- Opt out of the "sale" or "sharing" of Personal Information. We do not sell Personal Information, and only "share" it through Targeting cookies you have separately consented to — you may withdraw that consent, or opt out, at any time via the "Cookie Settings" link in the Website footer, or by emailing privacy@cl-power.com.
- Limit the use of Sensitive Personal Information (not currently applicable, as we do not knowingly collect Sensitive Personal Information through the Website).
- Not be discriminated against for exercising any of these rights.
To exercise any of the rights above, please contact us at privacy@cl-power.com. We may need to verify your identity before processing your request. We aim to respond within the timeframe required by applicable law — generally one month for GDPR requests (extendable by a further two months for complex requests), and 45 days for CCPA requests (extendable by a further 45 days).
10. Children's Privacy
The Website is intended for business use and is not directed at children. We do not knowingly collect Personal Information from anyone under the age of 16 (or the relevant age of digital consent in your jurisdiction). If you believe a child has provided us with Personal Information, please contact us so that we can delete it.
11. Data Security
We implement reasonable technical and organizational measures — such as access controls, encryption in transit, and confidentiality obligations for staff and vendors — designed to protect Personal Information against unauthorized access, loss, misuse, or alteration. No method of transmission or storage over the internet is 100% secure, and we cannot guarantee absolute security.
12. Third-Party Links
To ensure a smooth browsing experience, the Website may contain links to third-party websites, including those of distributors or partners. We have no control over such third parties, and you may choose whether to access links, content, products, and services provided by third parties. This Policy does not apply to those third-party sites, and we encourage you to review their privacy policies separately before submitting Personal Information to them.
13. Changes to This Policy
We may update this Policy from time to time to reflect changes in our practices or in applicable law. The "Last Updated" date at the top of this page indicates when it was last revised. We will indicate material changes on this page. If such revisions result in material changes to this Policy, we will notify you in a more prominent manner. In such cases, your continued use of our Website and services will constitute acceptance of the updated Privacy Policy. We encourage you to review this page regularly for the latest information regarding our Privacy Policy.
If any provision of this Policy is found to be unlawful, invalid or unenforceable under applicable law, the validity of the remaining provisions shall not be affected.
