## What it is
CryptPad is an open-source, end-to-end encrypted collaborative office suite that synchronizes documents in real time. It includes rich text, spreadsheets, presentations, forms, kanban, code/markdown, and whiteboard apps, with all data encrypted in the browser so even server administrators cannot read user content.

## Use cases
- collaboratively edit documents in real time without exposing content to the server
- self-host a private Google Docs alternative
- share encrypted documents via password-protected links
- run a privacy-first collaboration suite for a team or organization
- collect survey responses with encrypted forms
- manage team drives, calendars, and kanban boards privately

## When to choose
- you need end-to-end encryption for collaborative documents
- you want a self-hostable, open-source office suite
- privacy compliance or zero-knowledge storage is a requirement
- you need real-time collaboration across many document types

## When to avoid
- you need heavy offline desktop office features like advanced spreadsheet macros
- you require deep integration with third-party cloud ecosystems
- you need a native mobile or desktop application rather than a web app
