FAQ

Does Sonomos send my data to any external server?

No. Sonomos processes everything locally in your browser. Detection, masking, and image analysis all run on-device. The only external communication is for account authentication and payment processing. No page content, detected PII, or user text is ever transmitted.

Is Sonomos open source?

The extension itself is not open source. However, our architecture is transparent and built on a local-first, zero-data-exfiltration principle.

Which browsers are supported?

Any Chromium-based browser: Chrome 110+, Edge 110+, Brave, Arc, Vivaldi, and Opera. Firefox support is under evaluation.

Does Sonomos work on mobile?

Not currently. Browser extensions on mobile platforms have very limited capability. Sonomos is designed for desktop browsers where AI tools are primarily used.

Can my employer see what I detect or mask?

Only if you’re on a Teams plan. Team admins can see aggregate detection and masking statistics per member — but not the actual text content. Detection details stay on your device.

Does Sonomos slow down my browser?

The impact is minimal on modern hardware. AI-powered detection runs most efficiently on devices with GPU acceleration. Initial page scans may take 1–2 seconds on very long pages. Pattern-based detectors are effectively instantaneous.

What happens if Cloak misses something?

Send Guard acts as a fallback — it monitors form submissions and alerts you when PII is detected, even on platforms Cloak doesn’t natively cover. Together, Cloak + Send Guard provide defense in depth.

Can I use Sonomos with self-hosted AI tools?

Yes. Dagger (detection) works on any webpage regardless of the platform. Cloak’s automatic masking targets specific platforms, but Send Guard will activate on any site where PII is detected in form fields.
