Anthropic confirmed that its training opt-out has a carve-out, and its newest models now come with a mandatory 30-day retention window. The EU enforcement clock on AI labs starts ticking on August 2. A good week to remember the basics: hold your own copies.

Anthropic's opt-out has a ceiling (Tech Coffee House, June 9, 2026). The privacy policy update published on June 8, effective July 7, makes explicit that conversations flagged by Anthropic's safety systems can be used for training even if you opted out. The policy does not define what triggers a flag, and does not commit to notifying you when one occurs. Source

Mandatory 30-day retention on Anthropic's Mythos-class models (PYMNTS, June 2026). Alongside the June 9 launch of [personne] 5, Anthropic updated its retention policy: all prompts and outputs on Mythos-class systems are now stored for a mandatory 30 days. Microsoft responded by limiting employee access to the model over data retention concerns. When Microsoft worries about where its prompts sit, your retention settings deserve a look too. Source

OpenAI revised its European privacy policy (OpenAI, June 4, 2026). A fresh revision of the EU policy landed this month. If you use ChatGPT from Europe, skim the changes before they apply to you; the policies hub lists the effective dates. Source

EU AI Act: enforcement powers arrive August 2 (European Commission). Obligations for general-purpose AI models have applied since August 2025, but from August 2, 2026 the Commission can actually enforce them: information requests, model access, fines. The Digital Omnibus postponement provisionally agreed in May concerns high-risk systems and is still pending formal adoption. The transparency and copyright duties that matter for your data are on track. Source

Google retires Gemini Code Assist for individuals on June 18 (Google for Developers). The IDE extensions and Gemini CLI stop serving requests for the individual, AI Pro and AI Ultra tiers. A reminder that ownership has a third dimension beyond data and formats: access. A workflow that lives inside a provider's tier disappears with the tier. Source
