Does Cursor store my code on its servers?
Default data retention
Without Privacy Mode, Cursor may store code snippets and other data to improve its services, including for training its models. According to Cursor's documentation, this data is stored on their servers and may be retained for a period. The exact retention period isn't publicly specified in detail, but it's typically until you delete it or as needed for service improvement.
Cursor's privacy policy outlines that they collect usage data, code snippets, and other information. They state that they do not sell your data, but they may share it with third-party AI providers to generate responses.
- Default mode: code snippets may be stored and used for training.
- Data is sent to third-party AI providers like OpenAI or Anthropic.
- You can delete your data through account settings or by contacting support.
- Enterprise plans offer more control over data retention.
Privacy Mode and alternatives
When you enable Privacy Mode, Cursor commits to not storing your code or using it for training. In this mode, code is only held in memory for the duration of the request and then discarded. This is the recommended setting for private code.
If you need even more control, you can use Cursor with your own API keys for models like OpenAI or Anthropic, but note that those providers have their own data policies. For fully local processing, you can use local models via tools like Ollama, though Cursor's integration with local models may be limited.
- Enable Privacy Mode in Cursor's settings to prevent code retention.
- Use your own API keys to control data flow to AI providers.
- For maximum privacy, consider local models or self-hosted solutions.
- Review Cursor's privacy policy for the latest details.
Common mistakes
- Assuming Cursor never stores code; by default, it may store snippets for service improvement.
- Thinking that deleting your account immediately removes all data; some data may be retained for legal or operational reasons.
- Believing that using your own API keys makes you completely anonymous; the AI provider still receives your code.
