Payment processing through Stripe is covered by our Data Processing Agreement with them, ensuring your payment data is handled with appropriate GDPR protections. For additional information, you may review:

Digital whiteboard services operate under separate terms where users interact directly with the service and are advised not to include personal information.

Important: Rex Tutors' privacy policy applies to the personal data we process directly. It does not govern the data handling practices of the independent Affiliate Tutors once a referral is made.

Rex Tutors facilitates connections between students and independent Affiliate tutors.

Important: Affiliate tutors are independent professionals who contract directly with customers. Rex Tutors does not employ these tutors and they are not contracted to Rex Tutors. Affiliate tutors are not classed as third-party service providers as they do not process data on behalf of Rex Tutors.


For questions about how a tutor handles personal data, please contact them directly. Rex Tutors' privacy policy only covers data we process directly.

10. Data Retention

10.1 Retention Periods

  • Student Data: Marked for deletion after one year from the last tutoring session with the student, retained up until two years due to our annual review method
  • Email Communications: Marked for deletion after one year from the last tutoring session with the student, retained up until two years due to our annual review method
  • Session Materials: Marked for deletion after one year from the last tutoring session with the student, retained up until two years due to our annual review method
  • Financial Records: Retained for 6 years as required by UK tax law

10.2 Data Deletion

Automatic Deletion Process

We conduct data deletion reviews annually during September. When one year has elapsed since your last tutoring session, your personal data is marked for deletion and will be permanently removed during the next September review cycle. This annual review process means data may be retained for up to two years from your last session.

Service Continuity: The annual deletion cycle ensures continuity of service for returning students. Many students take breaks and return months later, and retaining session materials and progress information during this period allows us to provide better educational continuity when they resume tutoring.

Immediate Deletion Requests

You can request immediate deletion of your data at any time. Users who request immediate deletion under their GDPR rights (Section 12.3) do not need to wait for the September deletion cycle. We will process such requests within one month as required by law.

Returning Students

If you book new sessions after your data has been marked for deletion but before it is permanently removed, your data will be retained and the retention period will restart from your most recent session. We securely delete all personal data unless we are legally required to retain it for compliance or legitimate business purposes.
