# AI Privacy
The set of concerns around what happens to your data when you use AI platforms. Every prompt you send, every file you upload, and every conversation you have with a cloud AI service is data that goes somewhere.
## The core tension
Using AI effectively requires giving it context: your documents, your code, your ideas, your business data. But sending that context to a cloud provider means trusting them with it. The more context you provide, the better the output; the more you share, the greater the exposure.
## Key risks
- **[[AI Training Data Collection]]**: your prompts and responses may be used to train future models, effectively making your data part of the model's knowledge
- **Data retention**: providers may store your conversations for varying periods
- **IP leakage**: proprietary code, business strategy, or trade secrets sent to AI become data you no longer fully control
- **Employee exposure**: staff using consumer AI tools may inadvertently share confidential information
- **Third-party access**: data may be accessible to provider employees, subcontractors, or through legal requests
## Mitigation strategies
- Use **API access** instead of consumer chat interfaces (APIs typically don't train on your data)
- Use **enterprise plans** with explicit data handling agreements
- Run models locally with [[Running AI Models Locally|local inference]] ([[Ollama]], [[LM Studio]])
- Use [[AI Open Weight Models]] to keep everything on your infrastructure
- Review and configure opt-out settings on every platform
- Establish clear AI usage policies for teams and organizations
## The tradeoff spectrum
| Approach | Privacy | Capability | Cost |
|----------|---------|------------|------|
| Consumer chat (free tier) | Low | High | Free |
| API access | Medium | High | Per-token |
| Enterprise plan | High | High | Subscription |
| Local [[Small Language Models (SLMs)|SLMs]] | Maximum | Limited | Hardware |
| Local large models | Maximum | Good | Expensive hardware |
There's no free lunch. Maximum privacy with maximum capability requires significant hardware investment. Most people land somewhere in the middle: API access for sensitive work, consumer tools for general use.
