# FAQ

> Answers to the most common questions about MIRA.

<Accordion title="Is MIRA free to use?">
  MIRA the desktop app is free and open source (MIT licence). You supply your own AI provider API
  keys. Provider costs depend on the models you choose — Ollama is completely free (local only),
  while cloud providers charge per token.
</Accordion>

<Accordion title="Does MIRA send my data anywhere?">
  MIRA sends your messages and documents only to the AI provider you have configured. No telemetry,
  usage analytics, or crash reports are sent anywhere. See [Privacy &
  Data](../core-concepts/privacy-and-data) for the full outbound call list.
</Accordion>

<Accordion title="Which engine should I use — NAE or RLM?">
  * **NAE** is better for conversational reasoning, long document analysis, and tasks where you want sub-agents to specialise (research, writing, analysis).
  * **RLM** is better for tasks that benefit from code execution — data processing, calculations, structured data extraction, and iterative refinement.

  See [Reasoning Engines](../core-concepts/reasoning-engines) for a full comparison.
</Accordion>

<Accordion title="Can I use MIRA without an internet connection?">
  Yes — configure [Ollama](../configuration/providers/ollama) to run a local model. All reasoning
  and data stays on your machine.
</Accordion>

<Accordion title="Where is my data stored?">
  All data is stored in `mira.db` (SQLite) in your OS app data directory: - **macOS:**
  `~/Library/Application Support/MIRA/mira.db` - **Windows:** `%APPDATA%\MIRA\mira.db` - **Linux:**
  `~/.config/MIRA/mira.db`
</Accordion>

<Accordion title="How do I back up my skills and workflows?">
  Export them as JSON files from the Skills or Workflows view (⋮ → Export). You can also copy
  `mira.db` directly to back up everything at once.
</Accordion>

<Accordion title="Can I use MIRA on multiple machines?">
  Yes — export your skills, workflows, and eval profiles as JSON files and import them on each
  machine. There is no cloud sync — each installation is independent.
</Accordion>

<Accordion title="What file formats can I upload as documents?">
  PDF, DOCX, TXT, MD, CSV, JSON, and code files (`.py`, `.js`, `.ts`, `.rs`, `.go`, `.java`, `.cpp`,
  `.c`, `.yaml`, `.yml`, `.toml`, `.xml`, `.html`, `.css`). Maximum file size is 50 MB. See
  [Supported Formats](../features/document-context/supported-formats).
</Accordion>

<Accordion title="Why does MIRA ask for Gatekeeper / SmartScreen approval on first launch?">
  MIRA is distributed outside the Mac App Store / Microsoft Store. macOS and Windows require you to
  approve apps from unknown sources. See the [macOS installation
  guide](../get-started/installation/macos) or [Windows installation
  guide](../get-started/installation/windows) for the exact steps.
</Accordion>

<Accordion title="Can I contribute to MIRA?">
  Absolutely. See the [Contributing](./contributing) guide to get started.
</Accordion>

<Accordion title="How do I report a bug or request a feature?">
  Open an issue on [GitHub](https://github.com/satyendra2013/mira-app/issues) using the bug report
  or feature request template.
</Accordion>

<Accordion title="Does MIRA support Windows on ARM?">
  Not currently. Windows ARM support is planned for a future release. Track progress on [GitHub
  Issues](https://github.com/satyendra2013/mira-app/issues).
