About CryptPad

CryptPad is a private-by-design alternative to popular office tools and cloud services. All the content stored on CryptPad is encrypted before being sent, which means nobody can access your data unless you give them the keys.

A full suite of applications

CryptPad provides a full-fledged office suite with all the tools necessary for productive collaboration. Applications include: Rich Text, Spreadsheets, Code/Markdown, Kanban, Slides, Whiteboard and Forms.

End-to-end encrypted

All data on CryptPad is encrypted in the browser. This means no readable data leaves the user's device. Even the service administrators cannot see the content of documents or user data.

Private Collaboration

CryptPad is built to enable collaboration with features such as team drives, calendar, and sharing. It synchronizes changes to documents in real time. Because all data is encrypted, the service and its administrators have no way of seeing the content being edited and stored.

    I work for XWiki SAS. Two products we develop have it: - XWiki, a extensible wiki platform, experimentally [1] but soon to be fully supported - CryptPad [2], an end-to-end encrypted collaborative platform. And actually, CryptPad was accidentally born as a first attempt to have this feature in XWiki.

    It's not LibreOffice, but while revisiting CryptPad (which I thought was a multiplayer notepad like etherpad or codimd, except with an encryption key in the url fragment identifier) I was impressed to see that they're expanding to become an entire office suite.
