The service is available on the web and through an API, and describes use cases for analysts, agencies and data teams. All plans include live chat support, with documentation, tickets, a community portal and YouTube resources also listed. Windsor Group AG says it completed a SOC 2 Type II audit and processes personal data under UK GDPR and EU GDPR. It says customer data is encrypted at rest and in transit. A free plan and 30-day trial are available; paid plans start at $19/mo (annual).
