Providers and subprocessors

Planned product compute and storage in Germany. Hosting region, backup configuration and contractual data-processing terms require confirmation before customer data is onboarded.

Transactional email service. Recipient and message content pass through the mail provider. The application's queue clears recipient and content after delivery, retaining delivery evidence as configured.

Stripe-hosted checkout and billing. Haulbi receives customer, subscription and invoice references, not payment-card details. Stripe's own service providers may involve transfers outside the EEA; verify the applicable transfer instrument in the signed provider terms.

The Cal.com scheduler loads on the contact page only after the visitor allows external content. Its cloud service may process data in the United States. Confirm the deployment, provider terms and transfer mechanism before representing it as EU-hosted.

ZITADEL is used for identity; whether the deployment is self-hosted or uses ZITADEL Cloud must be confirmed for the final provider list. No external AI provider currently processes customer data. This list will be updated before any AI integration is enabled.

Vercel provides optional Web Analytics and Speed Insights for the marketing website after analytics consent. These services measure visits and page performance; they are separate from customer workspace data processing.
