Cursor temporarily caches file contents on its servers using encryption keys that exist only for the duration of a request; cached files are stated to be temporary, never permanently stored, and not used as training data when Privacy Mode is on.

This provision describes a temporary server-side file caching mechanism with a client-generated encryption model, and conditionally states that cached content is not used as training data, but only when Privacy Mode is enabled.
Interpretive note: The document does not define the maximum duration of 'temporary' caching, and the training data exclusion is conditional on Privacy Mode being enabled, which is not the explicit default state according to this document.
The document states that cached file contents are never permanently stored and are not used as training data when Privacy Mode is enabled; the training data exclusion is conditional on Privacy Mode being active, meaning cached content may be used as training data when Privacy Mode is off.

"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.— Excerpt from Cursor's Cursor Data Use & Privacy Overview
(1) REGULATORY LANDSCAPE: This provision implicates GDPR data minimization and security principles, as well as CCPA disclosure requirements for temporary processing of file content on third-party servers. The client-generated encryption model described may be relevant to security assessments under applicable data protection law. The FTC Act applies to the accuracy of representations about encryption and temporary storage practices. (2) GOVERNANCE EXPOSURE: Low to Medium. The provision describes a technical safeguard (client-generated encryption keys with request-scoped existence) that limits the risk of persistent exposure of cached file contents. However, the conditional nature of the training data exclusion (only when Privacy Mode is enabled) means that when Privacy Mode is off, cached file contents may potentially be used as training data. (3) JURISDICTION FLAGS: EU/EEA organizations should assess whether temporary server-side caching of file contents constitutes processing under GDPR and whether it is covered by applicable DPAs. The document's security page (cursor.com/security) is referenced for further detail but is not reproduced here. (4) CONTRACT AND VENDOR IMPLICATIONS: Enterprises assessing Cursor for use with sensitive codebases should review the full security documentation at cursor.com/security to understand the key management architecture and confirm the scope of 'temporary' caching. (5) COMPLIANCE CONSIDERATIONS: Compliance teams should verify that the encryption and key management description aligns with their organization's data security requirements, and confirm the maximum duration of the caching period to assess compatibility with data retention policies.
