SECURITY
Zero-Knowledge Security Architecture
Security isn't a feature we added. It's the foundation we built on. See how it works in practice.
Local-First Architecture
Sensitive data never leaves your device. All detection and transformation happens locally.
Zero-Knowledge Design
We cannot see, access, or reconstruct your private information. Ever.
Transparent Operation
Every action is visible. You always know what's being detected and how it's being handled.
No Data Retention
We don't store your prompts, conversations, or any content you process through Sonomos.
How We Protect You
On-Device Processing
All sensitive data detection runs entirely in your browser. Your content is analyzed locally, meaning it never travels to external servers for processing. See on-device AI and zero-knowledge processing for the underlying concepts.
Encryption Standards
Any communication with our services uses industry-standard TLS encryption. We follow security best practices for all infrastructure components.
Responsible Disclosure
Found a security issue? We welcome responsible disclosure. Contact us through our contact form.
Independent Verification
We submit Sonomos to independent, publicly verifiable security and privacy scans. Anyone can re-run these tests.
