Like any business, we work with third-party providers and affiliated companies to help us deliver, improve, protect, and promote our services.
Third-party sub-processors
When we act as a data processor on behalf of our customers, we use third-party processors (sub-processors) that have access to certain company personal data (as defined in our Data Processing Agreement). We use these sub-processors primarily for:
- infrastructure services
- customer support
- email notifications
We require all sub-processors to use personal data only to provide services to us. Access to systems is strictly controlled under our internal security policies (aligned with ISO 27001) and protected by two-factor authentication.
Where company personal data is transferred outside the EEA or Switzerland, we rely on an adequacy decision where applicable. For transfers to the United States, we rely on the EU-US Data Privacy Framework and, for personal data governed by the Swiss FADP, on the Swiss-US Data Privacy Framework where the importer is certified. Otherwise, we rely on the European Commission’s Standard Contractual Clauses, supplemented, where applicable, by the addendum recognized by the Swiss Federal Data Protection and Information Commissioner (FDPIC).

When required by law or for a legitimate interest, we may share your data with professional advisers acting as service providers, processors, controllers, or joint controllers, who provide consultancy, banking, legal, insurance, or accounting services. We ensure that we enter into data processing agreements with these subcontractors and implement technical and organizational measures that provide at least the same level of protection as we guarantee to our customers.
