Date: 30 October 2025 LinkedIn Will Commence Using Users' Personal Data for Training Generative AI Models from 3 November Privacy Commissioner's Office Reminds Users to Heed the Relevant Changes The Office of the Privacy Commissioner for Personal Data (PCPD) noted the employment-oriented social media platform LinkedIn would begin using users' personal data to train its generative artificial intelligence (AI) models from 3 November this year. Such data includes detailed information from users' profiles on the platform and public content posted on LinkedIn. LinkedIn would also update its privacy policy on the same day, and the updated policy would apply to users in the EU, the European Economic Area, Switzerland, Canada, and Hong Kong. The Privacy Commissioner for Personal Data, Ms Ada CHUNG Lai-ling, reminds LinkedIn users to pay attention to the changes in LinkedIn's privacy policy and to understand its relevant contents, in particular those relating to the use of users' personal data for training generative AI models, in order to decide whether to consent to such use. If users do not wish to authorise LinkedIn to use their personal data for training generative AI models, they may follow the steps in Annex 1 to change the default settings to withdraw their consent. In mid-September last year, LinkedIn updated its privacy policy to allow its use of users' personal data and content on the platform to train generative AI models for content creation. Following the intervention of the PCPD, LinkedIn suspended the use of personal data from Hong Kong users for the aforementioned purpose starting from 11 October, 2024. Between October 2024 and April 2025, the PCPD engaged with LinkedIn to understand the situation and review the details of its proposal. LinkedIn has committed to ensuring that Hong Kong users will retain control over the use of their personal data for generative AI models training purposes, and that such use will be in compliance with the Personal Data (Privacy) Ordinance (PDPO). The PCPD has already provided LinkedIn with recommendations to safeguard personal data privacy and will continue to monitor the situation to ensure that the personal data privacy of Hong Kong users is safeguarded. In addition, at the international level, in response to the growing trend of using personal data to train AI models, the PCPD co-sponsored the "Resolution on the Collection, Use and Disclosure of Personal Data to Pre-train, Train and Fine-tune AI Models" with other privacy protection authorities at the annual conference of the Global Privacy Assembly earlier. The resolution reaffirmed that the use of personal data for training AI models must comply with relevant laws and data protection and privacy principles, and emphasised the need to strengthen cross-border enforcement cooperation, etc. The resolution was unanimously adopted by more than 130 members at the conference.
