## What is Tenebrae Guardian?

Tenebrae Guardian puts AI privacy in your pocket.

The Guardian keyboard checks what you type before it reaches any AI assistant for sensitive data like Social Security numbers, credit cards, passwords, and API keys. When it spots something, it warns you and lets you hide it with a single tap, swapping the real value for a safe placeholder. Everything the keyboard inspects stays on your device.

The Guardian keyboard runs entirely on your device. It has no Full Access and makes no network calls — your keystrokes are never sent to us or anyone else.

Sign in to your free Tenebrae Solo account in the app to:
- See your protection activity at a glance
- Review alerts from your AI workflows

Tenebrae Guardian is built by a security team for people who use AI every day.

Note: the hosted Tenebrae Solo API (used by your automated workflows) is a separate, server-side service. The on-device Guardian keyboard transmits nothing; see our privacy policy for how each part handles data.
