# Quba — privacy layer for humans, agents, and systems

> Say yes to AI without handing over your data. One policy set across humans, agents, and systems.

Protect your sensitive data by enforcing a shared policy-set across your AI ecosystem so you can say yes to AI without handing over your data.

[Get started](/app)

## How it works

Your data stays protected before it leaves your environment.

From an AI chat to an LLM gateway, Quba keeps sensitive data masked as it moves through the tools and systems your team depends on.

Quba sits between your environment and the model across four paths: AI agents, an LLM gateway, AI training, and data processing. Sensitive values are masked before they leave your environment and restored on the way back.

## Built for Developers

One API call between your data and the model.

Install the SDK, add your key, wrap the call you already make. Quba swaps sensitive values for reversible tokens on the way out and restores them on the way back — any model, any provider, our cloud or yours.

npm install @quba/sensitive-data-protection

pip install quba-sensitive-data-protection
