Transfer mechanisms
For transfers to processors based in the United States we rely on the following safeguards:
- EU-US Data Privacy Framework (DPF) — the relevant processor is certified under the DPF program.
- Standard Contractual Clauses (SCC, Module 2) — Controller-to-Processor clauses per EU Commission Decision 2021/914.
- Swiss-US DPF / UK Extension — for transfers from Switzerland and the United Kingdom respectively.
Right to object
You may object to a new subprocessor within 30 days of notification. Where the objection cannot be reasonably accommodated, you may terminate your subscription with prorated refund.
Verification
Each processor's DPA contains audit/inspection rights pursuant to Art. 28(3)(h) GDPR. We monitor processor compliance through annual SOC 2 / ISO 27001 reports where available.
