Try our tools that use zero-knowledge architecture.
What is Zero-Knowledge?
Zero-knowledge means we know nothing about your data.
Everything happens on your device.
We cannot see what you do.
Benefits
- Privacy - We have no data to leak
- Security - Nothing to steal
- Speed - No server delays
- Freedom - No accounts needed
Real Examples
Password managers store encrypted data.
Secure messaging apps use end-to-end encryption.
Our tools process everything in your browser.
Frequently Asked Questions
How can I verify zero-knowledge architecture?
Open your browser's developer tools (F12), click the Network tab, and use any of our tools. You will see zero network requests to our servers during encryption or processing. You can also disconnect from the internet after the page loads—our tools work entirely offline because all processing happens in your browser.
What is zero-knowledge proof?
Zero-knowledge proof (ZKP) is a cryptographic method where one party can prove to another that they know a value, without revealing any information about the value itself. For example, you can prove you know a password without actually sending the password. This is different from our zero-knowledge architecture, which means we never see your data because all processing happens client-side.
How is zero-knowledge different from regular encryption?
Regular encryption protects data in transit and at rest, but the service provider usually has access to the encryption keys or performs encryption on their servers. Zero-knowledge architecture means the service provider never has access to your unencrypted data or keys—everything happens on your device. Even if our servers were compromised, attackers would only get encrypted data they cannot decrypt.
What are the limitations of zero-knowledge architecture?
Zero-knowledge architecture has some trade-offs: (1) No password recovery—if you forget your encryption password, no one can help you recover your data; (2) Browser dependency—you need a modern browser with JavaScript enabled; (3) Performance limits—very large files (GB+) may exceed browser memory limits; (4) No server-side features—some convenient features like automatic syncing or sharing require server access that zero-knowledge architecture avoids.
Why should I trust zero-knowledge services?
You do not need to trust us with your data because we never receive it. This is the core benefit of zero-knowledge architecture. However, you do need to trust that the code delivered to your browser is correct and has not been tampered with. This is why we use HTTPS, recommend verifying our code through browser developer tools, and support code auditing. The transparency of client-side processing means you can verify our claims yourself.
What happens if I lose my encryption key?
Your data is permanently lost. This is the fundamental trade-off of true zero-knowledge encryption. Because we never have your encryption key, we cannot recover it for you. There is no 'forgot password' feature, no customer support that can help, and no backdoor. Always store your encryption passwords in a secure password manager and consider keeping a physical backup in a safe location.
Does zero-knowledge protect against malware?
Zero-knowledge architecture protects your data from server breaches and prevents us from seeing your data, but it does not protect against malware on your device. If your computer has a keylogger, it can capture your password when you type it. If malware has access to your files, it can read decrypted data while you work with it. Always keep your devices secure with antivirus software and regular security updates.
Is zero-knowledge architecture compliant with privacy regulations?
Yes, zero-knowledge architecture helps with GDPR, HIPAA, CCPA, and other privacy regulations. Because we cannot access your data, we cannot process it, sell it, or accidentally expose it. This significantly reduces compliance risks. For GDPR, zero-knowledge means we are not a 'data controller' for your encrypted content. For HIPAA, client-side encryption helps meet technical safeguard requirements. Always consult with a compliance expert for your specific use case.
