Our Goal
We have thoroughly compared the dense privacy policies of today’s most popular AI programming to help you understand the critical privacy risks developers must be aware of. For instance, violating Anthropic’s commercial terms can get your API access revoked—the exact scenario that cut OpenAI off from Claude. Meanwhile, Cursor’s free tier uses your code for model training by default, as its ‘zero-retention’ feature is opt-in. We provided a comparison matrix for 7 top tools below, covering data retention, copyright assignment, and credential safety.

Factors to consider in a AI-Programming Tool
FAQ:
- Credential Safety: Will they upload my credential to the server for model training usage?
- Copy Right: Is the code own by me while using their service?
- Data Retention: How long does the data retention if they store our code in their server?
1. Credential Safety
Threat: AI assistant’s model potentially collect and scan the code that contains hardcoded credentials even users do not include in the prompt. The secret is then used in the model’s training data, creating a risk that an attacker could extract it via prompt injection, leading to a service breach.
Q&A:
No, these files only manage version control and do not stop an AI tool from reading an open file in your IDE.
Use a configuration file like .aiexclude, if available, to specify paths for the AI assistant to ignore.
2. Copyright
Threat: An AI tool generates code derived from a copyleft-licensed project. Integrating this into a proprietary product can cause license contamination, legally requiring the company to open-source its code and creating IP risk.
Q&A:
IP Indemnity is a provider's promise to defend you against copyright lawsuits from using their code, though specific terms and limits apply.
Not necessarily; a safer approach is using tools from providers that offer IP indemnity to transfer the legal risk.
3. Retention Period
Threat: Proprietary code submitted to an AI service may be stored on the provider’s servers, creating a risk of intellectual property exposure in the event of a data breach.
Q&A:
Select a provider or plan with a "zero-data retention" policy to ensure prompts are not stored after processing.
It guarantees the provider deletes your prompts and code after processing, offering the most secure option.
Use self-hosted or on-premise AI models to keep proprietary code within your own infrastructure.
