Is my browsing data encrypted before it leaves my machine?

Yes. The Privatemode proxy runs locally and encrypts all data before it leaves your machine. It also performs remote attestation to verify the integrity of the Privatemode service, ensuring end-to-end protection for every request Nanobrowser's agents make.

Does Privatemode store or retain data from Nanobrowser sessions?

No. Privatemode never learns from your data. All requests are processed using confidential computing, and no prompts, page content, or responses are retained after processing.

Do I need to install anything besides the Chrome extension?

You need Docker to run the Privatemode proxy locally or download and install the binary. The proxy is a lightweight container that handles encryption and attestation. Nanobrowser itself is a standard Chrome extension installed from the Chrome Web Store.

How does confidential computing affect browser agent performance?

Confidential computing adds a small overhead. Response times are comparable to conventional AI services, and your data stays encrypted in memory during processing.

Integrating Privatemode AI with Nanobrowser

Nanobrowser automates the web with a Planner that decides and a Navigator that acts, running in your own browser. Pointing both at Privatemode keeps what they read encrypted in memory even while it is processed.

The challenge

The agent works inside your logged-in session

Nanobrowser works inside your own browser, so the pages it reads include your logged-in accounts: bank dashboard, health portal, admin console, inbox. It sends that content to the model to decide what to do next. With a conventional provider, all of it is processed in plaintext on that provider's servers.

The solution

Both agents, one confidential provider

Nanobrowser lets you set a model for its Planner and its Navigator separately, and both can use the Privatemode proxy on your machine. The proxy encrypts each request before it leaves and the model runs in a hardware-isolated environment whose memory stays encrypted.

Run the Privatemode proxy

The proxy verifies the integrity of the Privatemode service using confidential computing-based remote attestation. The proxy also encrypts all data before sending and decrypts data it receives.

Add Privatemode as a custom provider in Nanobrowser

Install Nanobrowser from the Chrome Web Store and open its Settings panel. Add a custom OpenAI-compatible provider with the base URL set to your Privatemode proxy endpoint (http://localhost:8080/v1). Assign it to both the Planner and Navigator agents.

FAQ

Frequently asked questions about using Privatemode with Nanobrowser

Yes. Nanobrowser lets you assign different LLM providers to each agent. Once you add Privatemode as a custom OpenAI-compatible provider, you can assign it to both the Planner (which plans web tasks) and the Navigator (which executes browser actions), so all AI requests are encrypted.
