3. Changes

Klorra may add, remove, or replace subprocessors at any time, in its sole discretion. Updates are reflected on this page when made. KLORRA IS NOT OBLIGATED TO PROVIDE ADVANCE NOTICE OF SUBPROCESSOR CHANGES, except where such notice is expressly required by applicable law or by an executed Data Processing Addendum. Subscribers with an executed DPA should review that document for any negotiated notice or objection rights.

4. Internal Tooling (Non-Production)

Klorra also uses tools that do not process production Subscriber Content but support its corporate operations (for example, Google Workspace for internal email and file storage, Microsoft Outlook and Microsoft 365 for the founder's primary inbox, and 1Password for credential management). These tools are not subprocessors of Subscriber Content.
