We may share personal information in the following limited circumstances:
Service providers and processors: We engage trusted third-party vendors to perform services (payment processors, cloud hosting, analytics, CRM, shipping, and customer support). These providers are contractually bound to protect data and use it only for the agreed purposes.
Business transfers: In connection with a corporate transaction (e.g., merger, acquisition, sale of assets), personal data may be transferred to the acquiring entity subject to confidentiality and continued protection.
Legal and safety reasons: We may disclose data to comply with applicable laws, regulations, legal process, or to respond to lawful requests by public authorities. We may also disclose data when necessary to protect our rights, safety, property, or the public.
With your consent: When you authorize sharing (for example, a referral or joint project), we will share in accordance with your instructions.
AdTech is based in China and may transfer personal data to other countries for processing, including to service providers in jurisdictions with different data protection laws. Where required by law, we will implement appropriate safeguards (standard contractual clauses, data transfer agreements, or other lawful mechanisms) to protect personal information during cross-border transfers.

• enforce agreements.
Retention periods vary by data type and business needs; where feasible, we apply minimum retention necessary and securely delete or anonymize data when no longer required.
We implement reasonable administrative, technical, and physical safeguards to protect personal information against unauthorized access, loss, misuse, alteration, or destruction. Security measures include access controls, network protections, encryption where feasible, and staff training.
