Subprocessors
StudioFlow uses a small number of third-party services to run the product. This page lists every one of them, what it does, and where it is located — including the ones based outside the EU, because a subprocessor list that only mentions the convenient ones is worse than none.
The application and the database — where your clients, projects, documents and invoices live — run at Hetzner in Germany.
| Subprocessor | Role | Location |
|---|---|---|
| Hetzner Online GmbH | Application and database hosting | Germany (EU) |
| Backblaze, Inc. (B2) | Object storage — photos, galleries, documents, backups | United States(pending verification) |
| Cloudflare, Inc. | CDN and DNS | United States |
| Resend (Plus Five Five, Inc.) | Transactional email delivery | United States |
| Stripe, Inc. | Subscription billing and client card payments | United States, with EU entities |
| Google LLC | Calendar synchronisation and OAuth sign-inOnly for studios that connect Google Calendar or sign in with Google. No data reaches Google for studios that do not. | United States |
Rows marked "pending verification" carry the conservative value: we have not yet confirmed the region in the provider’s own console, so we state the provider’s default rather than the answer we would prefer. This page is updated the moment it is checked.
Changes
When a subprocessor is added, removed or moves region, this page is updated and existing customers are notified by email before the change takes effect, where the change is ours to schedule.
Data processing agreement
A countersignable data processing agreement (DPA / AVV) is available on request from info@studioflow.ch.
