Privacy and Security Measures

Understanding how Cursor AI handles your data is essential for your peace of mind. In this section, we will explore data handling and storage practices, along with the privacy mode and its guarantees.

Data Handling and Storage

Cursor AI integrates a sophisticated mechanism for managing your codebase. The platform semantically indexes the codebase allowing you to leverage AI effectively by referencing existing implementations. Here’s how it stores and handles data:

• The codebase indexing feature scans the opened folder, creates a Merkle tree of file hashes, and ignores files specified in .gitignore or .cursorignore.
• Every 10 minutes, only the changed files are uploaded, and the files, alongside their embeddings, are stored in Turbopuffer. This ensures efficient retrieval during AI responses.

You also have control over which files are sent to the servers by adding them to a .cursorignore file (Cursor Security Page).

Privacy Mode and Guarantee

Cursor AI offers a robust privacy mode to safeguard your data. When this feature is enabled, your code data is never stored or utilized for training by model providers. In fact, more than 50% of all Cursor users have privacy mode turned on.

Here’s how privacy mode works:

• Each server request includes an x-ghost-mode header that indicates privacy mode.
• Requests are managed according to whether the privacy mode is enabled or not.
• Cursor enforces privacy mode at both client and server levels, ensuring a comprehensive privacy guarantee.

If you decide to remove your data, you can delete your Cursor account along with all associated data and indexed codebases via the Settings dashboard. Cursor assures that all data will be completely removed within 30 days, providing an immediate deletion followed by a potential retrieval period from backups (Cursor Security Page).
