Sub-processors

Last updated 6 November 2026.

Every outside service that handles personal data for Sumly: what it does, what it receives and where it runs. The data is kept in Germany. We say so here at least 30 days before we add or replace a sub-processor, as the data processing agreement says.

Sub-processors

These handle the personal data in your workspace (your customers, your visitors and your team) on our behalf. Each is bound by a written agreement with the same data protection duties as our data processing agreement.

Hetzner Online GmbHGermany (EU)

The server that runs the site, the app's API, the visit collector and the databases.

Receives: All of it: workspace data and every visit and event.

Cloudflare, Inc.Global network; United States company

DNS and the network in front of the site and the collector.

Receives: Every request passes through it, with the IP address and user agent. Nothing is stored there.

Mailgun Technologies, Inc.EU region

E-mail: sign-in codes, team invitations, the reports you turn on and the monthly package to your accountant.

Receives: Recipients' addresses and what the mail carries, which for a report or a package includes customers' names, countries and payments.

OpenAI, L.L.C.United States

Ask, the chat on the site.

Receives: The question and the numbers the answer needs, which can include customer names and countries. Not used for training.

Google LLC (Firebase Cloud Messaging)United States

The app's notifications on Android.

Receives: The notice itself, such as a sale's amount, project and country, and the phone's push token.

Apple Inc. (Apple Push Notification service)United States

The app's notifications on iPhone and iPad.

Receives: The notice itself, such as a sale's amount, project and country, and the device's push token.

Services for our own data

These handle data we control ourselves, about the people who hold a Sumly account. They are not sub-processors; the privacy page explains how that data is handled.

Stripe, Inc.United States

Billing for Sumly's own plans.

Receives: The account holder's name, e-mail address, country and payment details. Card numbers stay with Stripe.

Google LLCUnited States

Sign in with Google, and Search Console when an owner connects it.

Receives: The account holder's name, e-mail address and Google id; the owner's own Search Console numbers.

Apple Inc.United States

Sign in with Apple in the app.

Receives: Apple's id for the account and the e-mail address the person chooses to share.

Discord Inc.United States

Our own notification channel for new sign-ups and support messages.

Receives: The account holder's or writer's name, e-mail address and message.

Your own payment providers and app stores are not on this list: Sumly only reads your data from them, with keys you give it. Nor is any place you tell Sumly to send something, such as your own Discord channel.

Where a service in the United States handles the data, the transfer rests on the EU-US Data Privacy Framework or on the European Commission's standard contractual clauses.
