# Ask Perplexity real questions without putting real data in them.

People query Perplexity like Google, but with specifics: "what does this lab result mean for someone with my history," "how do I appeal a charge on account 4012..." It feels like a private assistant, so people type details they'd never put in a public search bar.

The query doesn't stay private. Upstream models process it and use it to retrieve from external sources. The details that make your question specific are the ones that leave your device.

Locke detects the personal and confidential details in your query and masks them on your device. Perplexity still answers the question you have, without your private facts going out with it.

## The risk with Perplexity

Perplexity's search framing invites health, legal and financial specifics into questions. Models process the query and use it to retrieve from the open web, carrying those details off the device.

## How Locke helps

Locke detects and masks sensitive details in a query before it's submitted, so Perplexity answers the substance without your private facts leaving the device. The Early Access desktop app also screens Perplexity's API from a script or CLI, not only the website.

## Locke is free for one person

It runs on your device and masks sensitive data before a prompt is sent, on the AI tools it covers. Teams starts at $14.99 per seat a month.
