Terms of service
Privacy & data governance
Data retention policy
Sierra retains and processes Customer Personal Data for the duration of the applicable customer relationship and only as necessary to provide the Platform Services in accordance with the Agreement, DPA, applicable statements of work, documented customer instructions, and applicable law. Sierra maintains a data-retention schedule governing archival copies and their subsequent deletion.
Data archiving and removal policy
Upon expiration or termination of the Agreement, Sierra securely deletes Customer Personal Data through its standard deletion process. Before deletion, customers may request an export in a reasonably readable electronic format where technically feasible. Backup and archival copies are isolated, protected, and deleted in accordance with Sierra’s data-retention schedule, except where continued retention is required by applicable law. Sierra can provide written confirmation after deletion upon written request.
Data storage policy
Sierra hosts the Platform Services on AWS; Sierra’s corporate offices do not host Platform Services compute or storage. Customer Materials are logically isolated by unique tenant identifiers within Sierra’s multi-tenant architecture and are encrypted in transit and at rest, including backups, using industry-standard encryption. Encryption keys are managed and rotated using a hardware-security-module-backed cloud service. Access is restricted by role and least privilege, with multi-factor authentication for production and other privileged systems. Sierra performs periodic backups and replicates production data to a secondary region. Current subprocessors and their applicable countries or regions are documented in the Sierra Trust Center.

Requests concerning personal information that Sierra controls directly may be submitted to privacy@sierra.ai. Sierra verifies and processes eligible requests in accordance with applicable privacy law.
Requests concerning Customer Data, including Slack Data processed on behalf of a Sierra customer, should be directed to that customer. If Sierra receives such a request directly, Sierra promptly forwards it to the customer and assists with fulfillment under its Data Processing Addendum. Data is deleted through Sierra’s standard deletion process; backup and archival copies remain isolated and protected until deleted under Sierra’s retention schedule, except where retention is required by law.
