# Frequently asked questions.

Short answers reflect the approved product plan and current development status.

## Is mdquire free?

Yes. The app is distributed free under a proprietary license. Optional external tools and provider services can have their own terms and costs.

## Is mdquire open source?

No. The application source is private. Bundled open-source components keep their own licenses and notices.

## Can I download it now?

No public artifact is currently listed. A download action will appear only with a validated file, checksum, signing status and known limits.

## Which platforms are supported?

Windows and Linux are in development. macOS remains to verify and is unavailable until its gate passes. Every build before 1.0 is an unsigned pre-release.

## Does mdquire require an account or cloud storage?

No mdquire account is required. A book can remain a plain local Markdown folder. GitHub sign-in is only for GitHub work, and model-provider credentials are separate.

## Can an agent edit my book by itself?

Agent workflows are planned for M4 and M5. The design uses bounded jobs, approvals and proposals; the author decides which changes to apply. A mode whose confinement gate fails is unavailable.

## Does the site use analytics or email tracking?

No analytics, pageview beacon, tracking cookie, open pixel or click rewrite is part of the approved design. Email delivery and security processing still occur when the subscription service operates.

## How will unsubscribe work?

Every product-news email will include a human unsubscribe link and one-click unsubscribe headers. Revocation cancels pending confirmation and queued mail. The form is disabled until this secure backend is ready.
