SaaSFlow

Sub-processors

Earlier versions and changes

Last updated: October 6, 2026

This page lists all sub-processors that Walletguide GmbH engages to process customer data when providing the SaaSFlow services, as referenced in our Data Processing Agreement. We announce additions or replacements on this page and inform account owners by email at least 14 days before a new sub-processor starts processing customer data. A customer who does not agree with a change can object until then and terminate the contract with effect from that date; we refund fees already paid on a pro-rata basis (§ 5 of the Data Processing Agreement).

Internal business tools that are not part of the services, such as our own email and collaboration environment or our development tooling, are not sub-processors and are not listed here. They do not process the customer data the services hold on your behalf. Where such a provider processes personal data for which we are the controller, for example your contact details in an email to our support address, a data processing agreement is in place with it as well, and our privacy policy describes that processing.

Google Cloud Platform

Hosting of our server infrastructure, database and file storage, including storing of encrypted and unencrypted data of our customers. Also the AI processing behind our AI features, through Google's Vertex AI service: Anthropic's Claude models for the monthly performance report, the report chat and categorization suggestions, and Google's Gemini models for reading uploaded documents and suggesting mappings for connected tools (Finway, Pleo). Google Cloud runs these models itself, in EU data centers. Anthropic does not receive any customer data.

Amazon Web Services (AWS European Sovereign Cloud)

Bank connectivity providers

The following providers are not sub-processors. We list them here so you can see every company that handles your bank data when you use SaaSFlow.

Connecting a bank account is your choice. You can also add accounts manually and keep them current with CSV imports, in which case neither provider is involved. If you connect an account automatically, you authorize the provider yourself: in its own window, under its own terms and privacy policy. The provider signs in to your bank, retrieves the account and transaction data, and passes it to SaaSFlow on your instruction. For that access it acts as an independent controller under its own legal obligations, not on our behalf and not on our instructions. The only thing we send it is a pseudonymous technical ID so it can assign the connection to your account. Once the data has arrived in SaaSFlow, we process it as your processor under the Data Processing Agreement.

Because these providers are not sub-processors, the notice and objection procedure in § 5 of the Data Processing Agreement does not apply to them. We still announce changes to this section on this page.
