Privacy and troubleshooting

What stays on your machine, what leaves it and to whom, and what to do when something does not work.

What stays

  • Your keys and your conversations: in your browser’s localStorage. They are sent to the local server with each request, in a header, and nowhere else.
  • Your files: the working folder is read and written by tools on your machine.
  • Your exchange secrets: in your browser too; the local server opens the connection for each call and keeps nothing.

What leaves, and to whom

ToWhat
Your model providerYour messages, the agent’s context and its tool results, as any assistant would send. Through your subscription or your OpenRouter key.
BytNodeData queries, with your BytNode key.
Your exchangesThe calls the agent makes on your accounts, signed with your keys.
The webWhat WebSearch and WebFetch ask for.

When something does not work

An agent by subscription does not answer

Its vendor agent may not be signed in, or not installed. Open the gear, Auth, and look at its line: Se connecter means you are signed out, Installer means it is not on your machine. Sign-in happens in the vendor’s page and, for Claude and Copilot, in a terminal window: finish there, then come back.

The port is taken

npx bytnode-ai --port 3900

A key is refused

An OpenRouter key starts with sk-or-, a BytNode key with mk_. Vérifier says what the service answered.

Backtest fails

It needs Python with pandas on your machine. The error in the thread shows the Python output.

“Clock skewed by about N s”

An exchange refused a request dated too far from its own time. The application compensates the offset, but a clock that drifts faster than the ten-minute re-measurement needs syncing on your side.

A deposit does not show on the trading balance

On Bybit, OKX, KuCoin and Binance’s funding wallet, deposits land in a separate wallet. ExchangeBalance reads both and says where the funds are; Transfer with from: funding moves them.

Starting over

Clearing your browser’s site data for localhost:3777 removes keys, agents and conversations; deleting ~/.bytnode-ai removes workspaces, skills and installed agents. Nothing else was written anywhere.
