Franz Sub-processors
Effective 2026-04-19. Applies to Franz 6 and newer. If you are on Franz 5, please see the Franz 5 sub-processors list.
To support Franz in delivering its Services, Franz may engage third-party service providers to assist Franz with its data processing activities. When we work with these service providers in our capacity as a data processor, the third-party service provider is a sub-processor of Franz ("Sub-processor").
This page identifies the Sub-processors, describes where they are located, and what services they provide to us.
Franz is currently using the following Sub-processors:
| Sub-processor | Service provided | Location |
|---|---|---|
| DigitalOcean | Primary application hosting, API, and database for Franz account data. | EU (Frankfurt, Germany) |
| Hetzner | Application hosting, self-hosted Umami analytics, and self-hosted GlitchTip error monitoring. Umami uses no cookies and only anonymized visitor data. | EU (Germany) |
| Google Cloud (Vertex AI) | AI inference for optional Franz AI features such as email classification and summarization. | EU (europe-west4, Netherlands) |
| Stripe | Subscription billing and payment processing for new subscriptions. | Ireland (EU) with global payment network |
| Recurly | Legacy subscription management for customers who subscribed before the Stripe transition. Read-only — we no longer share new personal data with Recurly. | United States of America |
| Cloudflare | Object storage (R2) and AI proxy routing. | EU regions |
| Brevo | Transactional email (account verification, password reset, billing notifications) and email campaigns. | EU (France) |
Error monitoring runs on GlitchTip, which we self-host on Hetzner in Germany alongside Umami. GlitchTip is therefore not a separate third-party sub-processor.
Removed in Franz 6
The following sub-processors were part of the Franz 5 stack and are no longer used in Franz 6:
- Google Analytics — replaced by self-hosted Umami on Hetzner.
- Customer.io — marketing automation is no longer used.
- Facebook Pixel — conversion tracking is no longer used.
Recurly has not been fully dropped: new subscriptions go through Stripe, but legacy Franz 5 subscribers remain on Recurly for the lifetime of their subscription. We continue to read subscription status from Recurly for those accounts and do not share any new personal data with them.
Our business needs may change from time to time. For example, we may deprecate a Sub-processor to consolidate and minimize our use of Sub-processors. Similarly, we may add a Sub-processor if we believe that doing so will enhance our ability to deliver our Services. We will update this page to reflect additions and removals to our list of Sub-processors.
