Software without US sub-processors
EU and privacy-first SaaS verified to run with no US sub-processors in the data path, compared on ownership, hosting region, CLOUD Act exposure and sub-processor chain.
Software listed here is verified to operate with no US sub-processors in the data path: an EU/EEA/Switzerland operator, no US parent, and no US-incorporated processor in the chain. That combination (not server location alone) is what keeps data outside US CLOUD Act reach, because jurisdiction follows ownership and processor incorporation, not where the servers sit.
Some links on this site are affiliate links. We may earn a commission at no extra cost to you. Editorial signals and rankings are never influenced by affiliate relationships.
Software without US sub-processors, as listed on this page, means the operating company is incorporated in the EU, EEA or Switzerland, holds no US parent in its ownership chain, and routes no data through a US-incorporated processor at any point in the stack. That is a chain of three facts (operator incorporation, ultimate ownership and the full sub-processor list), and all three must hold. A product that is EU-hosted but owned by a US parent, or EU-owned but relying on a US-incorporated CDN or managed-database layer, does not clear the bar.
This hub spans all categories in the directory and is benchmarked on the same criteria used across every listing: hosting region, ownership signal, CLOUD Act exposure and the sub-processor chain. Every entry is sourced to the vendor's public sub-processor documentation and re-verified quarterly, so the list reflects current chains rather than a one-time assessment.
The CLOUD Act extends US government reach to data held by any company subject to US jurisdiction, regardless of where the servers physically sit. This is the mechanism that makes a US hyperscaler's "EU region" an incomplete answer to the sovereignty question: the operator's jurisdiction does not change when the data moves to a Frankfurt data centre. The same logic applies one level down. A vendor that is itself EU-incorporated can still re-introduce exposure through its sub-processors: a US-incorporated transactional email service, an analytics layer hosted on a US cloud, or a managed database run by a US subsidiary. Each of those processors is separately reachable under the CLOUD Act.
This is why the directory records ownership and sub-processors as separate, evidenced signals rather than deriving one from the other. A clean ownership chain with a single overlooked US processor is still an exposure. Both must be clear for the "no US sub-processors" flag to apply, and that combination is what this hub surfaces across every product category.

Start by narrowing to your category using the filters above. The "no US sub-processors" bar applies equally to password managers, cloud storage, email and analytics, but the sub-processor risk varies by product type. For each shortlisted product, open the profile and read the sub-processor chain against your own transfer-impact assessment: the layers where US processors most often re-enter an otherwise clean stack are transactional email, CDN and DNS, product analytics, and managed databases.
For regulated buyers (financial services, healthcare, public sector), any US-incorporated processor is typically a veto regardless of contractual safeguards, because the CLOUD Act operates independently of contractual terms. For solo founders and small teams, price and developer experience more often settle the decision than the sub-processor question; look for EU-owned products with a short, verifiable sub-processor list rather than spending disproportionate effort on formal transfer-impact assessments. For enterprise procurement, combine this hub with the certification filters (BSI C5, SecNumCloud, EUCS) to build a shortlist that satisfies both the jurisdictional and the security-audit requirements. The filters above match by category, hosting country or compliance score.
