The Case for ownCloud
- ownCloud stores all data exclusively in Germany, EU, under European jurisdiction. Unlike Microsoft OneDrive, which is subject to the US CLOUD Act and FISA Section 702, ownCloud cannot be compelled by foreign governments to hand over your data.
- ownCloud offers a Data Processing Agreement (DPA) that is fully aligned with GDPR Article 28. There is no legal ambiguity about data transfers or adequacy decisions — your data processor is European, and the law that governs it is European.
- As an open-source solution, ownCloud gives you full code transparency. You can verify that the software does what it claims, audit it for security vulnerabilities, and even self-host it for maximum control — something that is simply not possible with Microsoft OneDrive.
- You can try ownCloud for free before committing. This makes it easy to evaluate whether it meets your needs alongside — or as a replacement for — Microsoft OneDrive, without any financial risk.

ownCloud vs Microsoft OneDrive — FAQ
Is Microsoft OneDrive GDPR compliant?
Microsoft OneDrive may offer GDPR compliance features and EU data residency options, but as a US-headquartered company, it remains subject to the US CLOUD Act and FISA Section 702. These laws can compel US companies to hand over data regardless of where it is stored. The EU-US Data Privacy Framework provides some safeguards, but its predecessors (Safe Harbor and Privacy Shield) were both invalidated by the European Court of Justice. ownCloud, as a European company, is not subject to these US laws at all.
How does ownCloud compare to Microsoft OneDrive in features?
ownCloud offers File sync and share, Collaborative document editing, Granular permission controls, Version history and file locking, and 5 more features. While Microsoft OneDrive's ecosystem may be larger due to its market position, ownCloud covers the core functionality that most teams need. The trade-off is typically between breadth of integrations (Microsoft OneDrive) and data sovereignty with regulatory certainty (ownCloud).
Can I migrate from Microsoft OneDrive to ownCloud?
Yes. Most European software providers, including ownCloud, offer migration tools or documentation to help you transition from US-based services. Under GDPR Article 20, you have the right to data portability — meaning Microsoft OneDrive must provide your data in a machine-readable format. The migration process varies in complexity depending on your data volume and integrations, but for most teams it can be completed within a few days to a few weeks.
