LibreOffice
A complete, free office suite – documents, spreadsheets, presentations – that runs entirely on your own computer. No subscription, no cloud, no tracking.
Quick facts
It's completely free with no subscription ever, opens Word and Excel files without much fuss, and runs entirely offline so nothing about your documents leaves your computer.
Complex Word or Excel formatting can shift slightly when opened, and there's no built-in real-time collaboration the way Google Docs or Microsoft 365 offer.
Why does it score 97?
Registered in Berlin, Germany – a full EU member state.
Developed by The Document Foundation, a non-profit funded by donations and corporate members rather than investors.
LibreOffice runs entirely on your own computer, so there's no cloud infrastructure or server handling your documents at all.
Fully open source (MPL/LGPL) and GDPR-compliant by nature – there's no data collection to be accountable for in the first place.
