Meta AI
Meta says it uses public information from adult accounts and interactions with AI at Meta features to develop and improve generative AI models, with a right to object.
Eligible public posts, comments, and Meta AI interactions may be used for generative AI development and improvement.
Meta provides a right-to-object flow for future use of eligible information.
The cited Meta page is specific about public information and AI interactions; it does not present private messages as the core training source in that disclosure.
The public GenAI page explains future-use objections, but not a simple user-facing retention period for all data categories.
The public page explains data categories and objections rather than a plain-language human-review summary.
