LOPs writes local files to manage the Python environment, store provider settings, run sidecar services, and optionally log API traces.

Where Things Live

Storage locations

Install config

dotLOPs config in your app-data folder

UV binary

dotLOPs uv folder in app-data / Application Support

Python environment

The folder you chose on the Environment page

Project config

.lops/ next to the .toe (when using folder-tier config)

SideCar services

sidecars/ under the LOPs base folder

What Gets Stored

• Python environment and installed packages.
• ChatTD provider, model, and endpoint settings.
• MCP client/server configs (session, project, folder, or user tier).
• Agent profiles and skills.
• SideCar environments, server files, and ports.
• Per-operator outputs — generated images, exports, ratings, file outputs.
• API traces, when enabled.

API Keys

ChatTD stores keys locally in the project COMP. Some operators may also store provider keys in dotLOPs or environment-adjacent JSON files. If you are sharing a project, check provider settings and operator configs before sending the .toe or project folder.

Traces

CAUTION Traces can contain prompts and responses

When Trace API Call is enabled on an Agent, LOPs writes JSON trace files that can include prompts, responses, tool calls, and errors. Review them before sharing.

Traces are written to LOP_history/traces/ under the LOPs Python environment folder. LOPs does not upload traces anywhere.

Your local model server (LM Studio, Ollama, etc.) may also keep its own logs — those are separate from LOPs traces.

Sharing a Project

Before sending a project to someone else:

1. Back up or stub operators you do not want to share internals for.
2. Check for operator output folders that should be excluded.
3. Review API key storage and provider settings.
4. Review trace files if including the environment folder.
5. The recipient should run the Environment page on their own machine — do not expect the original venv path to work.

Uninstalling

Deleting the TouchDesigner project does not remove the LOPs Python environment, SideCar environments, UV binary, or app-data config. Remove those folders manually for a full cleanup.
