Security and privacy

Blender Bridge is built so that your Blender takes commands only from your account and the people you let in. Every command is checked against your account's access, and another person reaches your Blender only with your consent. Usage statistics contain none of your prompts, AI conversations, code, scenes or images. Here is how it works.

Who can send commands to Blender

Only the Blender Bridge app on the same computer. Blender accepts commands on the computer's internal address (127.0.0.1) and is not open to the network.
Only with signed access. Every command that runs in Blender needs a valid signed access grant tied to your account and subscription. Without a sign-in, commands don't run.
The browser extension also needs your pairing key. Your Blender Bridge app issues it, and without it the extension can't work with your Blender.

Working from another device and together

Commands through the Blender Bridge server. With the plugin or the server-address connection, the server passes commands to the computer you chose, from any device. The scene is built and stored in your Blender.
You decide who sees your computers. The chat sees the computers linked to your account and the ones someone has shared with you.
Owner consent. In a shared session, the other person's commands reach a computer only after its owner agrees. Either side can end the session.

What usage statistics contain

Usage statistics contain only technical events, such as a command finishing or failing. They never contain:

your prompts and AI conversations;
the code the AI writes;
scenes, models, images or file names;
operation names.

Files you download from the chat. When you download a render, model or scene from the chat, the file passes through the Blender Bridge server. It is kept there for 24 hours behind a private signed link issued to your chat, then deleted.

Your files

Saved scenes, renders and models are regular files on your computer, in your project folder. They stay yours after your subscription ends. Blender Bridge's file tools keep existing results by default: export never overwrites a file, and saving over one takes an explicit request. The AI's instructions tell it to ask before changing work you didn't mention.

Updates

The app and Blender Bridge MCP update through signed releases: the app checks the update's signature before installing it. The browser extension updates through the Chrome Web Store.
