Hi there,

I let check Claude the changes which come into force on September 28th.

Please note. Claude can make mistakes. Check the changes by yourself before accepting.

Here is Claude's analysis, evaluation and tips:

Critical Changes in Anthropic's Terms of Service & Privacy Policy Analysis May 2025 vs September 2025 Versions

MOST CRITICAL CHANGE: Fundamental Shift in Model Training Policy

OLD POLICY (May 2025): "We will not train our models on any Materials that are not publicly available, except in two circumstances: (1) If you provide Feedback to us, or (2) If your Materials are flagged for trust and safety review"

NEW POLICY (September 2025): "We may use Materials to provide, maintain, and improve the Services and to develop other products and services, including training our models, unless you opt out of training through your account settings. Even if you opt out, we will use Materials for model training when: (1) you provide Feedback to us regarding any Materials, or (2) your Materials are flagged for safety review"

ASSESSMENT: This is a massive privacy regression. Anthropic now defaults to using ALL your conversations for training unless you explicitly opt out. This fundamentally changes their data usage model from opt-in to opt-out.

CHANGE 2: New Financial Services Restriction

NEW ADDITION (September 2025): "To rely upon the Services, the Materials, or the Actions to buy or sell securities or to provide or receive advice about securities, commodities, derivatives, or other financial products or services, as Anthropic is not a broker-dealer or a registered investment adviser"

ASSESSMENT: New legal liability protection for Anthropic, restricting legitimate use cases for users.

CHANGE 3: Expanded Data Collection

OLD POLICY (May 2025): Listed device information, IP address, identifiers

NEW POLICY (September 2025): Added: "device location" and expanded "Technical Information" definitions

ASSESSMENT: More invasive data collection with location tracking now explicitly mentioned.

CHANGE 4: Enhanced Surveillance Language

NEW ADDITION (September 2025): Explicit mention that flagged content will be used for "AI safety research" and "advance AI safety research"

ASSESSMENT: Broader justification for monitoring and analyzing user conversations.

CHANGE 5: Increased User Liability for Actions

The new version emphasizes more strongly that users are fully liable for all "Actions" Claude takes on their behalf, with more explicit warnings about responsibility.

ASSESSMENT: Anthropic is shifting more legal risk to users while reducing their own liability.

CHANGE 6: Weakened Transparency Obligations

NEW VERSION includes more exceptions for when Anthropic does NOT need to inform users about account suspensions or content removal.

ASSESSMENT: Less accountability and transparency in enforcement actions.

CHANGE 7: Expanded Research Definition

The definition of "research" has been broadened to include "societal impact of AI models" which is very broadly interpretable.

ASSESSMENT: Gives Anthropic wider latitude to use user data for various research purposes.

CHANGE 8: New Non-User Privacy Policy Reference

The new policy references a separate "Non-User Privacy Policy" for data obtained from third parties.

ASSESSMENT: Indicates expanded data collection from sources beyond direct users.

CHANGE 9: Modified Cancellation Rights

NEW RESTRICTION: "The 14-day cancellation period will not reset if you change subscription tiers or cancel and then resubscribe" NEW RESTRICTION: "If you are not paying under a subscription billing model, you do not have a right to a refund of unused tokens"

ASSESSMENT: Reduced consumer protections and refund rights.

CHANGE 10: New Data Portability Rights (Positive)

NEW ADDITION: Complete new section about data switching and portability rights.

ASSESSMENT: This is actually a positive change, giving users more control over their data and ability to switch providers.

OVERALL ASSESSMENT:

The changes represent a significant shift away from privacy-protective practices toward a more typical Big Tech approach:

• Default data harvesting for AI training

• Expanded surveillance and monitoring

• Reduced user protections

• Increased corporate liability shields

• More invasive data collection

This is particularly concerning from a company that positions itself as focused on "AI Safety" and responsible AI development.

RECOMMENDATIONS:

1. DO NOT accept the new terms until September 28, 2025 (use the full grace period)

2. IMMEDIATELY check your account settings for the new training opt-out option when it becomes available

3. Review and adjust ALL privacy settings before accepting new terms

4. Consider alternative AI services as backup options (OpenAI, Google, others)

5. Be more cautious about sensitive information in conversations

6. Document your current conversation history if you want to preserve it

7. Consider the implications for any business or professional use cases

The direction is clearly toward more data collection and less user privacy protection, which represents a concerning departure from Anthropic's stated principles.

Non-commercial use only. You agree that you will not use our Services for any commercial or business purposes and we and our Providers have no liability to you for any loss of profit, loss of business, business interruption, or loss of business opportunity.
