If you enable “[Privacy Mode](https://cursor.com/help/security-and-privacy/privacy#how-do-i-enable-privacy-mode)” in Cursor’s settings: Customer Data will not be used for training by Cursor. Cursor maintains zero data retention (ZDR) agreements with all providers, and AI model providers will not store or train on your data. However, please note that subject to their policies, model providers (including Cursor) may run risk classifiers to detect violations of terms and usage policies, and if your prompts or conversations trigger abuse detectors your data may be stored for investigation and deleted in accordance with their retention policies. Non-ZDR models will be designated as such or require an admin to opt-in to enable the model for your workspace. See documentation from [SpaceXAI](https://x.ai/legal/faq-enterprise), [OpenAI](https://developers.openai.com/api/docs/guides/your-data#default-usage-policies-by-endpoint), [Anthropic](https://privacy.claude.com/en/articles/7996866-how-long-do-you-store-my-organization-s-data) and [Meta](https://dev.meta.ai/help/policies-and-privacy/zero-data-retention) for more details about their retention policies.

If you choose to turn off “Privacy Mode”: we may use and store codebase data, prompts, editor actions, code snippets, and other code data and actions to improve our AI features and train our models. Some of our inference providers may temporarily access and store model inputs and outputs to improve our inference performance; this data is deleted after use.

Other notes:

Even if you use your API key, your requests will still go through our backend! That's where we do our final prompt building.

• Requests go through Cursor's backend even if you use your own API key Use & Processing

We temporarily cache file contents on our servers to reduce latency and network usage. The files are encrypted using unique client-generated keys, and these encryption keys only exist on our servers for the duration of a request. All cached file contents are temporary, never permanently stored, and never used as training data when privacy mode is enabled.
