Its all local. Ollama is the application, deepseek and llama and qwen and whatever else are just model weights. The models arent executables, nor do the models ping external services or whatever. The models are safe. Ollama itself is meant for hosting models locally, and I dont believe it even has capability of doing anything besides run local models.

Where it gets more complicated is “agentic” assistants, that can read files or execute things at the terminal. The most advanced code assistance are doing this. But this is NOT a function of ollama or the model, its a function of the chat UI or code editor plugin that glues the model output together with a web search, filesystem, terminal session, etc.

So in short, ollama just runs models. Its all local and private, no worries.

Yeah, you’re totally right.

All image processing happens locally.

And then it mentions that you can just open the index.html directly, which means it uses clientside javascript or wasm and runs on the browser. You are correct!

On the topic of word choice, you might be right. Save or open might be better.

Just because its run locally, doesnt mean it still isnt a web server. The software could run anywhere and be accessed over the network. The image optimization happens at the server, so download and upload are more accurate.
