4. OUR LEGAL BASIS FOR PROCESSING
Where the EU General Data Protection Regulation (GDPR) or similar legislation applies, we rely on the following legal bases:
- Consent (Article 6(1)(a)) - for processing enquiry form data and for setting non-essential cookies. You may withdraw your consent at any time.
- Legitimate interests (Article 6(1)(f)) - for maintaining server logs to keep the Site secure and functioning, and for our business-to-business communications with you.
- Legal obligation (Article 6(1)(c)) - for records we are required to keep under tax, accounting and export control law.
5. INTERNATIONAL TRANSFERS
We are a company established in the People's Republic of China, and the Site is hosted on servers located in mainland China. This means that the personal information you submit through the Site will be transferred to, stored in and processed in China, which may not provide the same level of data protection as your country of residence.
Where we transfer personal data out of the European Economic Area, the United Kingdom or Switzerland, we take steps to protect it, including relying on the European Commission's Standard Contractual Clauses where applicable, and applying technical and organisational safeguards such as encryption in transit and access controls.
If you do not wish your information to be transferred to China, please contact us by telephone or email instead of using the contact form, and we will discuss alternative arrangements with you.
If your enquiry relates to Russia or the CIS, it may also be handled by the company in Russia identified in section 1 above, in which case your information is processed in the Russian Federation.
6. WHO WE SHARE YOUR INFORMATION WITH
We do not sell your personal information. We share it only with:
- Service providers who support our operations, such as our website hosting and cloud infrastructure provider. These providers process data on our instructions and are bound by confidentiality obligations.
- Our staff and, where relevant, affiliated engineering personnel who need the information to respond to your enquiry.
- Professional advisers, such as our accountants and legal advisers, where necessary.
- Government authorities, courts or regulators, where we are required to disclose information by law.
7. HOW LONG WE KEEP YOUR INFORMATION
- Enquiry form data: retained for 3 years from the date of our last contact with you, so that we can follow up on your project and honour warranty obligations. If you ask us to delete your data earlier, we will do so (see section 8), unless we are required to retain it by law.
- Server log data: retained for 12 months.
- Records relating to an actual order or contract: retained for the period required by Chinese tax, accounting and export control law.

If you are located in the EU/EEA, you also have the right to lodge a complaint with the supervisory authority in your country of residence, place of work or where the alleged infringement took place.
9. COOKIES AND ANALYTICS
The Site uses a small number of cookies. Strictly necessary cookies are required for the Site to function and are set on the basis of our legitimate interests. Analytical cookies help us understand how visitors use the Site so that we can improve it; these are only set with your consent where consent is required by law.
At present we do not use advertising cookies, and we do not use any third-party tracking or analytics service on the Site. If we introduce analytics tools in the future, we will update this Privacy Policy to name them, and where the law requires it we will ask for your consent before any non-essential cookie is set.

We use appropriate technical and organisational measures to protect your personal information against unauthorised access, alteration, disclosure or destruction.
