Data Processing Agreements
We have executed Data Processing Agreements (DPAs) with all subprocessors that process personal data. For GDPR-covered transfers, we rely on Standard Contractual Clauses where required. Enterprise customers may request copies of relevant DPAs by contacting contact@exhibitstamppro.com.
Notification of Changes
We will provide at least 14 days' notice before adding a new subprocessor that processes personal data. Notice will be provided via email to account administrators and by updating this page. If you object to a new subprocessor, you may terminate your subscription before the change takes effect.
