Sub-processors

Last updated August 28, 2026. We will update this page before adding a new sub-processor that handles personal information.

VeinFusion uses the following sub-processors to operate the Platform. Each is bound by contract to process data only for the purposes below, and vendors that touch protected health information operate under a business associate agreement (BAA).
