Hetzner Online GmbH
Hosts the AmbassadorFlow application and MySQL databases. Data is encrypted in transit (TLS). Access is restricted to authorised operations staff. Privacy policy: hetzner.com/legal/privacy-policy.
Twilio SendGrid
Delivers system emails (account notifications, GDPR export delivery to merchants) and merchant-branded emails to referral ambassadors (reward codes, programme messages). Merchants may authenticate their own sending domain via SendGrid. Privacy policy: twilio.com/legal/privacy.
Stripe Payments Europe Ltd
Processes subscription payments for Clients who sign up outside the Shopify App Store billing flow (for example WooCommerce merchants and direct registrations on go.ambassadorflow.com). Stripe receives payment card details directly; AmbassadorFlow stores only a payment token and limited billing metadata. Stripe is not used to process End Customer (referral programme) data and is not engaged for Shopify App Store subscription charges (those are billed by Shopify). Privacy policy: stripe.com/privacy.
MillionVerifier
Optional fraud-prevention check when a customer signs up to a merchant’s referral programme on the join page. Only the email address is sent to MillionVerifier. Merchants can disable this in Security & Anti-Fraud settings. Privacy policy: millionverifier.com/privacy-policy.
Shopify Inc.
When a merchant installs the AmbassadorFlow app on Shopify, we receive and process customer and order data via Shopify’s APIs and webhooks (including customers/data_request, customers/redact, and shop/redact for GDPR compliance). We may write short-lived shop metafields (for example a pre-rendered thank-you page offer) keyed by a hashed email identifier with a maximum retention of 24 hours.
Shopify acts as the merchant’s platform provider; the merchant’s relationship with Shopify is governed by Shopify’s own terms and privacy policy.
Changes
We will update this page when we add or replace sub-processors. Material changes will be reflected in our Privacy Policy.
