Zero Data Retention (ZDR) for Claude Code is available to qualified accounts on Claude for Enterprise. When ZDR is enabled, prompts and model responses generated during Claude Code sessions are processed in real time and not stored by Anthropic after the response is returned, except where needed to comply with law or combat misuse.
ZDR is not included in the standard Claude for Enterprise plan and cannot be enabled from your admin settings. It is available to qualified accounts and requires separate enablement by Anthropic. If your organization requires ZDR, contact sales or your Anthropic account team to confirm eligibility.
ZDR on Claude for Enterprise gives enterprise customers the ability to use Claude Code with zero data retention and access administrative capabilities: ZDR for Claude Code on Claude for Enterprise applies only to Anthropic’s direct platform. For Claude deployments on Amazon Bedrock, Google Cloud’s Agent Platform, or Microsoft Foundry, refer to those platforms’ data retention policies.

​
ZDR scope

ZDR covers Claude Code inference on Claude for Enterprise.
ZDR is enabled on a per-organization basis. Each new organization requires ZDR to be enabled separately by your Anthropic account team. ZDR does not automatically apply to new organizations created under the same account. Contact your account team to enable ZDR for any new organizations.

​
Route Claude Code traffic to your ZDR organization

ZDR applies to requests that authenticate into a ZDR-enabled organization. If a developer signs in to Claude Code with a personal account or with an API key from a different organization, those sessions are not covered. To restrict login to your ZDR organization, deploy the forceLoginMethod and forceLoginOrgUUID managed settings; see Restrict login to your organization.

​
What ZDR covers

ZDR covers model inference calls made through Claude Code on Claude for Enterprise. When you use Claude Code in your terminal, the prompts you send and the responses Claude generates are not retained by Anthropic. This applies to every model available to ZDR organizations. Some models require data retention and are not available under ZDR; see Model availability under ZDR.

​
What ZDR does not cover

ZDR does not extend to the following, even for organizations with ZDR enabled. These features follow standard data retention policies:

​
Features disabled under ZDR

When ZDR is enabled for a Claude Code organization on Claude for Enterprise, certain features that require storing prompts or completions are automatically disabled at the backend level: These features are blocked in the backend regardless of client-side display. If you see a disabled feature in the Claude Code terminal during startup, attempting to use it returns an error indicating the organization’s policies do not allow that action. Future features may also be disabled if they require storing prompts or completions.

​
Model availability under ZDR

Claude Fable 5 is not available for organizations with zero data retention enabled. This model class requires data retention, so requests from ZDR organizations cannot be served by it. The model is either absent from the /model picker for ZDR organizations or shown as disabled with a notice that disabling ZDR is required, and the server rejects requests for it regardless of client configuration. Other models remain available under ZDR. Fable 5 is not the default model, and the best alias, which resolves to Fable 5 where it is available, resolves to Opus for organizations where it is not, including ZDR organizations.

​
Data retention for policy violations

Even with ZDR enabled, Anthropic may retain data where required by law or to address Usage Policy violations. If a session is flagged for a policy violation, Anthropic may retain the associated inputs and outputs for up to 2 years, consistent with Anthropic’s standard ZDR policy.

​
Request ZDR

To request ZDR for Claude Code on Claude for Enterprise, contact sales or your Anthropic account team. Your account team will submit the request internally, and Anthropic will review and enable ZDR on your organization after confirming eligibility. All enablement actions are audit-logged. If you are currently using ZDR for Claude Code via pay-as-you-go API keys, you can transition to Claude for Enterprise to gain access to administrative features while maintaining ZDR for Claude Code. Contact your account team to coordinate the migration.
