2.3 Cookies and Similar Technologies

We use only strictly necessary cookies and localStorage to operate the Site. We do not use advertising cookies, tracking cookies, or third-party analytics cookies. Specifically:

• No profiling: We do not build user profiles, track users across sites, or engage in behavioral advertising.

3. How We Use Your Information

We use the information we collect for the following purposes and on the following legal bases:

3.1 To Respond to Your Inquiries (Legitimate Interest)

When you submit a contact form, we use your name, email address, and message content to understand your requirements and to communicate with you about your project or inquiry. This is necessary to provide the service you have requested.

3.2 To Operate and Improve the Site (Legitimate Interest)

We analyze aggregated, anonymized server logs and usage patterns to monitor Site performance, detect and prevent technical issues, and improve the content and structure of the Site. This processing does not involve making automated decisions about individuals.

3.3 To Comply with Legal Obligations

We may process and retain your information as required by applicable laws and regulations, including those of the People's Republic of China, or to respond to lawful requests from public authorities.

4. How We Share Your Information

We do not sell, rent, or trade your personal information to third parties for their marketing purposes. We may share your information only in the following limited circumstances:

• Service providers: We may engage trusted third-party vendors to perform functions on our behalf — such as hosting the Site (e.g., Firebase Hosting by Google) or processing email. These providers are contractually bound to process data only on our instructions and to implement appropriate security measures.
• Legal requirements: We may disclose information if required to do so by law, court order, or governmental regulation, or if we believe in good faith that disclosure is necessary to protect our rights, your safety, or the safety of others.
• Business transfers: In the event of a merger, acquisition, reorganization, or sale of all or a portion of our assets, information held by us may be among the assets transferred. You will be notified via a prominent notice on the Site of any change in ownership or use of your information.

5. Data Retention

We retain your personal information only for as long as is necessary to fulfill the purposes for which it was collected, or as required by applicable law:

• Contact form submissions: Retained for the duration of our business relationship plus a period of three (3) years after our last communication, after which the data is securely deleted.
• Server logs: Retained in identifiable form for a maximum of thirty (30) days, after which they are either anonymized or deleted.
• Legal holds: Information subject to a legal hold or preservation order will be retained until the hold is lifted.

6. Data Security

We implement and maintain appropriate technical and organizational measures to protect your personal information against accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access. These measures include:

• Transport Layer Security (TLS) encryption for all data transmitted between your browser and our servers.
• Access controls limiting personal data access to authorized personnel with a legitimate business need.
• Regular security reviews and updates to our infrastructure and dependencies.
• Firebase security rules and Google Cloud Platform security features for hosted data.

While we strive to protect your information, no method of electronic storage or transmission over the internet is 100% secure. We cannot guarantee absolute security of your data.
