Third-party services that process customer data on ConvynHQ's behalf.

Last updated: 2026-07-06

Effective date: July 6, 2026

Purpose

This document lists the third-party service providers ("Subprocessors") that ConvynHQ LLC ("ConvynHQ") engages to process personal information on behalf of its customer organizations in connection with the ConvynHQ platform (the "Service").

ConvynHQ uses each Subprocessor for a defined operational purpose, under written contract, and subject to confidentiality obligations and security commitments at least as protective as those ConvynHQ has agreed to provide to its customers. ConvynHQ does not use any Subprocessor for advertising, marketing, or for any purpose unrelated to providing the Service.

Mobile phone numbers and opt-in status are not shared with third parties for marketing purposes.

Notification of changes

ConvynHQ updates this list when Subprocessors are added, removed, or replaced. Customers who have signed a Data Processing Agreement with ConvynHQ will receive notice prior to a new Subprocessor being engaged, and may object on data-protection grounds within the timeframe set out in the Data Processing Agreement. All other customers should consult this page for the current list.

To subscribe to email notification of Subprocessor changes, contact privacy@convynhq.com.

Stripe-related disclosure

When a customer organization uses Stripe Connect to accept payments from its own end users (for tickets, tables, or donations), end-user payment data flows directly to the customer organization's connected Stripe account. ConvynHQ does not receive, store, transmit, or process payment card numbers. In that flow, Stripe operates under the customer organization's own agreement with Stripe.

Hosting and infrastructure

The Service is hosted in the United States on infrastructure operated by the Subprocessors above. Customers seeking specific data-residency commitments should contact privacy@convynhq.com to discuss available options.
