Subprocessors
Last updated: March 2026
Overview
A subprocessor is a third-party service that processes data on our behalf in order to provide or support the GentlePrep app. We carefully select subprocessors that maintain high standards of security and privacy.
We keep the number of subprocessors to the minimum necessary to operate GentlePrep. Each subprocessor is listed below with a description of what data it processes and where it is located.
