With consent, Google may set and read __gads, __gpi, IDE, NID, DSID, and test_cookie; process IP, user-agent and approximate location; build interest-based advertising profiles; and share data with TCF v2.3 vendors you authorise.

Some third parties (notably Google) may transfer personal data outside Hong Kong. Such transfers rely on the EU–U.S. Data Privacy Framework, Standard Contractual Clauses, and the PDPO requirements where applicable.

Under the PDPO, GDPR, and CCPA/CPRA you may access, correct, request erasure, restrict processing, port your data, and withdraw consent. Lodge complaints with the Office of the Privacy Commissioner for Personal Data (PCPD, Hong Kong), the Information Commissioner (UK), or the California Privacy Protection Agency.
