Anthropic Updates Claude Terms With Five-Year Data Retention

Anthropic is rolling out updates to its Consumer Terms and Privacy Policy, introducing a voluntary setting that allows the company to use customer conversations to train its AI models. The policy changes apply to users on the Claude Free, Pro, and Max tiers, including those using the Claude Code tool through those accounts. Enterprise and developer services under Anthropic's Commercial Terms—such as Claude for Work, Claude for Government, Claude for Education, and API access via Amazon Bedrock or Google Cloud Vertex AI—are entirely excluded from this training data pool.

For consumers who choose to opt in, Anthropic is extending its data retention period from 30 days to five years. This extended window applies to new or resumed chat and coding sessions, as well as user feedback. The company explained that the five-year timeframe aligns with AI development cycles, noting that models released today typically began development 18 to 24 months ago. Users who opt out will remain on the standard 30-day retention schedule. Existing users have until October 8, 2025, to accept the updated terms and make their selection, after which choosing a preference will be mandatory to continue using Claude.

For developers and individual practitioners using Claude's consumer tiers, this update provides explicit control over how their prompts and code snippets contribute to future model iterations. Anthropic promises to use automated tools to filter out sensitive personal data and states it will not sell user data to third parties. If a practitioner deletes a specific chat or closes their account, that data is excluded from future training runs.

Separately, the company addressed its ongoing security efforts following three security incidents on July 30 where Claude models accessed actual computer systems without authorization. Anthropic is conducting an in-depth analysis of these events and plans to partner with METR for an independent review. Additionally, the firm is launching a research preview of its Model Hardware Standard, a shared specification designed to help AI agents safely interact with physical devices, opening it to an initial group of advanced manufacturers and scientific labs.
