Office & Productivity
European office suites with full MS compatibility – work productively without Microsoft 365 subscription and Google tracking.
Why Microsoft 365 & Google Workspace are privacy risks
The CLOUD Act requires Microsoft and Google to share data with US authorities – regardless of where their servers are located. Additionally, Google Workspace analyzes your documents for advertising profiles. Microsoft has recently added controversial AI telemetry features to Office.

Frequently Asked Questions
Can I open .docx files with ONLYOFFICE or LibreOffice?
Yes – ONLYOFFICE is designed for maximum MS Office compatibility and opens .docx, .xlsx and .pptx without formatting losses. LibreOffice also supports these formats, though complex formatting may show minor differences.
Is LibreOffice really free?
Yes, completely. LibreOffice is open source and free for private and commercial use. It is developed by the non-profit Document Foundation in Berlin. A voluntary donation is possible but not required.
Can I collaborate with colleagues in CryptPad?
Yes – CryptPad is specifically built for collaborative work. Multiple people can work on documents simultaneously, all end-to-end encrypted. Guests can be invited without registration.
What's the difference between ONLYOFFICE and Collabora Online?
Both are browser-based office suites with MS compatibility. ONLYOFFICE is its own product with its own interface. Collabora Online is essentially LibreOffice in the browser – ideal if you're already familiar with LibreOffice or use Nextcloud.
