6. International Data Transfers
We are located in China and some of our service providers are located in the United States and other countries. Your personal information may therefore be transferred to and processed in countries outside the European Economic Area (EEA), the UK, or your country of residence, which may have different data-protection laws.
Where we transfer personal information from the EEA/UK to a country not deemed to provide an adequate level of protection, we rely on appropriate safeguards, such as the European Commission’s Standard Contractual Clauses (SCCs) or the UK International Data Transfer Addendum. You may request a copy of the relevant safeguards by contacting us.

- Newsletter subscription data: until you unsubscribe.
- Analytics data: 14 months, in line with our analytics tool settings.
- Server and security logs: up to 12 months.
When retention periods expire, we delete or anonymize the data.
8. Data Security
We implement appropriate technical and organizational measures to protect personal information, including encrypted transmission (HTTPS/TLS), access controls, and staff confidentiality obligations. However, no method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.
9. Your Rights (EEA / UK and Other Regions)
Depending on your location, you may have the following rights regarding your personal information:
- Access — obtain confirmation of whether we process your data and a copy of it
- Rectification — correct inaccurate or incomplete data

- Withdraw consent — at any time, where processing is based on consent
- Lodge a complaint — with your local data protection supervisory authority (in the EEA, the authority in your country of residence or work; in the UK, the ICO)
