Is Sellsy GDPR compliant?

How do teams switch from Salesforce to Sellsy?
Teams considering a move from Salesforce, Stripe and HubSpot to Sellsy are usually drawn by its crm workflow fit. EU Alts has not independently verified Sellsy's exposure to the US CLOUD Act, so treat any CLOUD Act or Schrems II conclusions as provisional.
