CryptPad

Overview

CryptPad is the leading privacy-focused alternative to Google Docs and the broader Google Workspace suite. Developed in France, it was built from the ground up with a “zero-knowledge” philosophy. This means that unlike mainstream providers who scan your documents for data mining or AI training, CryptPad is technically unable to see what you are writing.

The suite provides a familiar interface for anyone moving from Google Docs. It includes editors for rich text, spreadsheets, presentations, polls, kanban boards, and whiteboards. Because all encryption and decryption happen on your computer, you get the convenience of the cloud with the security of a local, private file.

Key Features

Zero-Knowledge Collaboration

CryptPad allows multiple users to edit the same document at the same time. While this looks like Google Docs, the underlying technology is fundamentally different. Every keystroke is encrypted before it leaves your computer and is only decrypted by your collaborators who hold the secret key.

CryptDrive

Your CryptDrive acts as your command center. It is an encrypted file system where you can organize your documents into folders, manage access permissions, and store tags for easy searching. Since the file structure itself is encrypted, the server doesn’t even know your file names.

Secure Forms and Polls

Beyond document editing, CryptPad offers an encrypted alternative to Google Forms. This is particularly useful for sensitive data collection, as the responses are encrypted from the moment the participant hits “submit” until you open them in your browser.

Privacy & Security

The cornerstone of CryptPad is its use of the WebCrypto API. When you create a document, a unique cryptographic key is generated in your browser’s URL fragment (the part after the #). This fragment is never sent to the server. Consequently, the server hosts the data but lacks the “password” to read it.

CryptPad is also “Privacy by Design” regarding your identity. You can use the service as a guest without an account, or create an account without providing an email address or any personally identifiable information.

Getting Started

1. Visit the Instance: Go to CryptPad.fr or choose a community-hosted instance.
2. Create an Account (Optional): Click “Sign Up.” You only need a username and password. Remember your password—there is no “forgot password” link because the developers cannot access your account!
3. Start a Pad: Click on “Rich Text” or “Sheet” from the dashboard to create your first document.
4. Share Securely: Click the “Share” button. You can share a link that allows others to view or edit. The encryption key is included in the link you send.

Who Is It Best For?

CryptPad is ideal for:

• Journalists and Activists: Who need to collaborate on sensitive information without fear of surveillance.
• Privacy-Conscious Businesses: Who want to protect their intellectual property from service providers.
• Education: Teachers and students who want a collaborative environment that respects student data privacy laws (GDPR compliant).
• Self-Hosters: Tech-savvy users who want to run their own office suite on their own hardware.

Final Verdict

CryptPad is perhaps the most impressive “drop-in” privacy replacement for Google Docs available today. While it may lack some of the deep integration features of the Google ecosystem (like integrated Gmail/Calendar sidebars), its commitment to end-to-end encryption is unmatched.

If you are looking to de-Google your workflow without losing the ability to collaborate with others in real-time, CryptPad is the gold standard. It proves that you don’t have to sacrifice productivity for privacy.
