Why choose OpenCloud over Microsoft OneDrive?

The decisive argument is data jurisdiction. Microsoft OneDrive is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes — the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

OpenCloud removes that overhead. As a Germany-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors — health, public administration, finance — that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.

Frequently asked questions

Is OpenCloud a good alternative to Microsoft OneDrive?
Yes — OpenCloud is one of the top-ranked European alternatives to Microsoft OneDrive in our directory, covering the same cloud & hosting use case. It is headquartered in Germany, keeping your data under EU law by default.
What's the main difference between OpenCloud and Microsoft OneDrive?
The biggest difference is jurisdiction: OpenCloud is based in Germany and operates under GDPR and EU data-protection law, while Microsoft OneDrive is headquartered in US and may transfer data outside the EU. For regulated industries or organisations following Schrems II guidance, this difference is decisive.
Is OpenCloud GDPR-compliant?
OpenCloud is a European company based in Germany, so GDPR compliance is the default operating model — not a bolt-on. No transfer impact assessment is required for EU customers, unlike when using Microsoft OneDrive.
How do I migrate from Microsoft OneDrive to OpenCloud?
Start by exporting your data from Microsoft OneDrive (most providers offer an export in their settings). Then import into OpenCloud using its native import tool or migration guide. Running both in parallel for a week catches any feature or workflow gaps before you fully switch.
