Sub-processors
Last updated March 2026
For each sub-processor that we use, we apply the principles of least privilege. This means that each third-party system shall only have access to the minimum data required to fulfill its purpose. All sub-processors are bound by data processing agreements that impose materially the same data protection obligations as those in our Data Processing Agreement.
