I'd say yes, from the Exhibit A: Anthropic Data Processing Addendum section in the commercial ToS , at least from how I as a layman understand it. From how I understand it, they don't even train the safety model when using the API: Commercial Terms of Service A. Services 4. Anthropic may not train models on Customer Content from paid Services.

r/ClaudeAI on Reddit: Anthropic’s New Privacy Policy is Systematically Screwing Over Solo Developers
September 10, 2025 -

TL;DR: Is Anthropic forcing a choice between privacy and functionality that creates massive competitive disadvantages for independent developers while protecting enterprise customers?

What’s Happening

By September 28, 2025, all Claude users (Free, Pro, Max - including $100+/month subscribers) must decide: let Anthropic use your conversations for AI training and keep them for 5 years, or lose the memory/personalization features that make AI assistants actually useful.

There’s no middle ground. No “store my data for personalization but don’t train on it” option.

The Real Problem: It’s Not Just About Privacy

This creates a two-tiered system that systematically disadvantages solo entrepreneurs:

If You Opt Out (Protect Privacy):

  • Your AI assistant has amnesia after every conversation

  • No memory of your coding patterns, projects, or preferences

  • Lose competitive advantages that personalized AI provides

  • Pay the same $100+/month for inferior functionality

If You Opt In (Share Data):

  • Your proprietary code, innovative solutions, and business strategies become training data

  • Competitors using Claude can potentially access insights derived from YOUR work

  • Your intellectual property gets redistributed to whoever asks the right questions.

Enterprise Customers Get Both:

  • Full privacy protection AND personalized AI features

  • Can afford the expensive enterprise plans that aren’t subject to this policy

  • Get to benefit from innovations extracted from solo developers’ data

The Bigger Picture: Innovation Extraction

This isn’t just a privacy issue - it’s systematic wealth concentration. Here’s how:

  1. Solo developers’ creative solutions → Training data → Corporate AI systems

  2. Independent innovation gets absorbed while corporate strategies stay protected

  3. Traditional entrepreneurial advantages (speed, creativity, agility) get neutralized when corporations have AI trained on thousands of developers’ insights

Why This Matters for the Future

AI was supposed to democratize access to senior-level coding expertise. For the first time, solo developers could compete with big tech teams by having 24/7 access to something like a senior coding partner. It actually gave solo developer a chance at starting a sophisticated innovative head start and an actual chance of creating a foundation.

Now they’re dismantling that democratization by making the most valuable features conditional on surrendering your competitive advantages.

The Technical Hypocrisy

A billion-dollar company with teams of experienced engineers somehow can’t deploy a privacy settings toggle without breaking basic functionality. Voice chat fails, settings don’t work, but they’re rushing to change policies that benefit them financially.

Meanwhile, solo developers are shipping more stable updates with zero budget.

What You Can Do

  1. Check your Claude settings NOW - look for “Help improve Claude” toggle under Privacy settings

  2. Opt out before September 28 if you value your intellectual property

  3. Consider the competitive implications for your business

  4. Demand better options - there should be personalization without training data extraction

Questions for Discussion

  • Is this the end of AI as a democratizing force?

  • Should there be regulations preventing this kind of coercive choice?

  • Are there alternative AI platforms that offer better privacy/functionality balance?

  • How do we prevent innovation from being systematically extracted from individual creators?


This affects everyone from indie game developers to consultants to anyone building something innovative. Your proprietary solutions shouldn’t become free training data for your competitors.

What’s your take? Are you opting in or out, and why?
