Processor transparency should match the real stack
Buyer review moves faster when the public list, the DPA packet, and the hosted stack all match.
Trust Center
Subprocessors and hosted service providers
Whispr relies on a short hosted stack for infrastructure, transactional email, and billing. This page lists those providers so privacy, security, and procurement teams can review the same information.
A short, current list without mixed vendor history
The list focuses on the providers currently used for hosting, notifications, and billing-related processing.
Review with DPA, privacy, and security together
Subprocessors alone do not explain roles, access, deletion, or legal transfer language.

How to read this list
- Cloudflare is the primary hosting and storage layer for the current product.
- Resend is the current transactional email provider used for service notifications.
- Stripe is relevant for billing-related processing only, not for every deployment workflow.
Changes to the stack should be reflected across trust and contract materials
If the hosted stack changes, this page, the DPA materials, and any signed documentation should be updated together. That is the safest way to keep procurement, security review, and privacy review aligned.
