Zero Friction uses carefully selected subprocessors to ensure its platform is safe, reliable, and functional.
In this article we provide insight into:
which subprocessors we use;
for what purpose they are used;
where data is processed (data residency);
how these subprocessors are categorized.
This information forms part of our Trust Center and supports customers in their own compliance and due diligence obligations (such as GDPR).
Categorization
Zero Friction distinguishes three categories of subprocessors:
Infrastructure Subprocessors
Essential for hosting, monitoring and technical operation of the platform.
Core Functionality Subprocessors
Required for core Zero Friction functionalities such as communication, payments, and reporting.
Optional Subprocessors
Optional integrations that are only used when a customer activates this functionality.
Each category is explained separately below and shown in its own table.
