Sub-Processors

Last updated: May 2026

Tutorbase uses the third-party vendors below as sub-processors to operate the Service. Each is bound by a data processing agreement with us, processes personal data only on our instructions, and provides commitments on security and international transfers consistent with our Privacy Policy and Data Processing Addendum.

We will give subscribers at least 30 days' notice before adding a new sub-processor that handles personal data, where reasonably practicable. To receive change notifications, email privacy@tutorbase.com with the subject "Subscribe to sub-processor changes."

Notes

  • “Region” describes the primary processing location of the sub-processor. Some operate global edge networks; the headline region reflects where their controllers and primary data stores are operated.
  • “Data” lists the categories of personal data most relevant to that sub-processor. It is not necessarily exhaustive and excludes derived or operational metadata.
  • Where a sub-processor is based outside your country of residence, transfers are governed by Standard Contractual Clauses, the UK International Data Transfer Addendum, or equivalent transfer mechanisms as described in our Privacy Policy.
  • For an overview of our broader security practices, see our Security overview.
