Cookies and Google Analytics
Our website uses necessary, functional and analytics cookies.
Functional cookies may remember choices such as your preferred website language.
With your consent, we use Google Analytics 4 to understand how visitors find and use our website. This may include information about page visits, traffic sources, approximate location, browser, device and website interactions.
Google Analytics uses identifiers and cookies to measure website activity. Google prohibits Analytics customers from sending personally identifiable information to Google Analytics and requires website operators to disclose its use.
You can accept, reject or manage optional cookies through our Cookie Consent banner. You may change or withdraw your choices at any time using the Cookie Preferences control on the website.
More information is available in our Cookie Policy.
Marketing Communications
Where you subscribe to newsletters or request marketing information, we may use your name, email address, company and interests to send relevant Sunways news, product updates, events and industry information.
You may unsubscribe at any time by:
- using the unsubscribe link in an email;
- changing your communication preferences where available; or
- contacting us at
service@sunways-tech.com.
Withdrawing marketing consent does not affect the lawfulness of processing carried out before withdrawal.
How We Share Personal Data
We may share personal data where reasonably necessary with:
- Sunways affiliates and regional offices;
- authorised distributors, installers and service partners;
- website hosting, cloud, email and IT service providers;
- customer relationship management and support providers;
- analytics and Cookie Consent providers;
- professional advisers, auditors and insurers;
- public authorities, regulators, courts or law-enforcement bodies where required;
- a purchaser or successor in connection with a corporate restructuring, merger or transfer of business.
Service providers may process personal data only for authorised purposes and subject to appropriate contractual and security requirements.
We do not disclose personal data to unrelated parties except as described in this Privacy Policy or where required by law.
International Data Transfers
Sunways operates internationally. Your personal data may therefore be processed in countries other than the country in which you are located, including China, Germany and countries in which relevant Sunways affiliates, partners or service providers operate.
Data protection laws in those countries may differ from those in your country.
Where required by applicable law, we take appropriate measures to protect internationally transferred personal data. These measures may include contractual safeguards, access restrictions, security controls and assessments of the receiving party.
How Long We Keep Personal Data
We retain personal data only for as long as reasonably necessary for the purpose for which it was collected, including legal, accounting, warranty, security and dispute-resolution requirements.
The retention period depends on the type of information:
| Data category | Retention approach |
|---|---|
| General inquiries | Until the inquiry is resolved and for a reasonable follow-up period |
| Customer and project records | For the duration of the business relationship and applicable statutory periods |
| Warranty and support records | For the warranty or service period and any additional period required for claims or legal obligations |
| Marketing subscriptions | Until consent is withdrawn, the subscription is cancelled or the information is no longer required |
| Analytics data | According to the retention settings configured in Google Analytics and applicable consent requirements |
| Security and server logs | For a limited operational and security period, or longer where an incident is under investigation |
| Consent records | For as long as necessary to demonstrate and manage the visitor’s consent choices |
Sunways should insert its confirmed internal retention periods before final publication where specific periods are required.
Data Security
We use reasonable technical and organisational measures designed to protect personal data against:
- unauthorised access;
- accidental loss;
- misuse or alteration;
- unlawful disclosure;
- destruction or damage.
These measures may include access controls, encryption where appropriate, system monitoring, backups, vulnerability management and staff confidentiality obligations.
No method of internet transmission or electronic storage is completely secure. We therefore cannot guarantee absolute security.
Your Data Protection Rights
Depending on your location and applicable law, you may have the right to:
- request access to your personal data;
- request correction of inaccurate or incomplete data;
- request deletion of your data;
- request restriction of processing;
- object to certain processing;
- receive certain data in a portable format;
- withdraw consent at any time;
- object to direct marketing;
- lodge a complaint with a competent data protection authority.
The GDPR and similar laws require organisations to inform individuals clearly about these rights and make them reasonably easy to exercise.
To exercise a right, contact:
service@sunways-tech.com
We may need to request reasonable information to verify your identity before responding.
Children’s Privacy
This website is intended primarily for business customers, distributors, installers, partners and other professionals.
We do not knowingly collect personal data from children through this website. If you believe that a child has submitted personal data to us, please contact us so that we can review and, where appropriate, delete the information.
Embedded Content and External Websites
Our pages may contain or embed content from external services, including videos, maps, social media platforms, documents and external websites.
These providers may collect information about your device and interactions, use cookies or apply their own privacy policies. Optional third-party content should only load in accordance with your Cookie Consent choices where consent is required.
Links to external websites are provided for convenience. Sunways is not responsible for the privacy practices of independent third-party websites.

Accordingly, the standard WordPress provisions relating to public comments, Gravatar profiles, public user accounts, login cookies and password-reset emails do not apply to ordinary website visitors.
If these features are enabled in the future, this Privacy Policy will be updated before or when the relevant processing begins.
