Data & Permissions

Runs models entirely on your device; local use needs no account and no internet after download.

Local models run 100% on-device and work fully offline once downloaded
No account required to install or run local models
Prompts and responses from local models are not collected or used for training
Optional cloud (-cloud) models send content to Ollama servers, processed transiently and not stored (per privacy policy)

Known Risks

A few things to weigh before relying on it.

Build signing and notarization are not independently verified here
Past CVEs (e.g. CVE-2024-37032, CVE-2026-7482) required network access to the API, which has no built-in authentication — keep it bound to localhost
Optional cloud (-cloud) models send prompts off-device; only local models are fully offline
A paid cloud tier now exists, though the core local app remains free and open source

Verification reflects the version listed above. Practices may change between releases. How we verify ›

Our verdict: the most straightforward way to run open LLMs entirely on your own machine — private by default, needing no account and no cloud, with signing and audit status we could not independently confirm.

Ollama is an open-source tool that lets you download and run open large language models — including Llama, Gemma, Qwen, DeepSeek and gpt-oss — 100% locally on your own hardware. A single command pulls a model from its 200+ model library and runs it, with GPU acceleration on NVIDIA, AMD and Apple Silicon.

Because local models run entirely on-device, Ollama works offline once a model is downloaded, and its privacy policy says prompts and responses from local models are not collected or used for training (limited usage metadata such as app version may be). It is a CLI-first tool that also ships a desktop chat app for macOS and Windows, plus a local REST API with OpenAI- and Anthropic-compatible endpoints. Optional cloud models are reachable through the same API, but those send content to Ollama's servers.
