# Your prompts aren’t ours to leak.

Locke processes your content on your device and never sends it to our servers. We can't leak, hand over or lose what we never receive. [See how it works](https://sonomos.ai/product/).

## Detection and masking run on your device

Sensitive data never leaves it.

## Nothing on our side to see

We can't see or reconstruct your private information.

## You see every detection

What was flagged, and what happened to it.

## We keep none of your prompts or conversations

Nothing you process through Locke is stored on our side.

## Processing, transport and disclosure

### On-device processing

All detection runs on your device, and nothing is sent out for analysis. Compare [on-device AI](https://sonomos.ai/glossary/on-device-ai/) and [zero-knowledge processing](https://sonomos.ai/glossary/zero-knowledge-processing/) with typical cloud tools.

### Standard TLS in transit

The little traffic there is, such as loading this site, uses standard TLS. Your sensitive data isn't part of it: Locke masks it before anything is sent.

### Report a security issue

We welcome responsible disclosure. [Contact us](https://sonomos.ai/contact/).

## Scans anyone can re-run
