Privacy Policy

Effective 2026‑05‑11. Applies to the MDraft app for macOS and the website at mdraft.net.

MDraft is a native macOS app that runs locally on your Mac. We designed it so your documents, edits, and personal preferences never leave your device unless you explicitly send them somewhere. This policy describes what that means in detail.

Plain‑English summary

• We do not collect any personal information from you.
• We do not track you.
• We do not use third‑party analytics, advertising, or telemetry SDKs.
• We do not have user accounts or logins.
• We do not sync your documents to any cloud.
• We do not sell, rent, or share any user data, because we don't have any.

How MDraft uses your Mac

MDraft reads, edits, and saves Markdown files locally on your Mac. It runs inside the macOS App Sandbox: every file or folder it opens is scoped to an explicit grant from you via the system file picker, the sidebar's "Add Folder" button, the AI Context Files feature's read‑only home directory access, or the Web Import save dialog. MDraft cannot access anything else without you choosing it.

What MDraft stores on your Mac

All of the following live in standard, sandbox‑scoped macOS locations on your device:

• Your preferences (appearance, font, sidebar width, last‑used Web Import save folder) in the app's UserDefaults.
• A session‑state file recording open windows, open documents, and pinned folders so MDraft can restore your session on next launch. Stored under ~/Library/Application Support/MDraft/.
• A SQLite cache (MetadataCache.sqlite) of file metadata for the AI Context Files feature — paths, modification times, and the role classifier's decisions for each discovered Markdown file. Used to keep the sidebar responsive.
• A SQLite store (Library.sqlite) for any documents you've explicitly added to your local Library via the right‑click menu.
• A semantic search index (SemanticIndex.json) of locally‑computed text embeddings for documents you've saved, generated by Apple's on‑device NLEmbedding framework.

Nothing in any of these stores is transmitted off your Mac by MDraft. If macOS itself backs them up — e.g., via Time Machine, iCloud Drive's Desktop & Documents Folders, or another backup tool you've configured — that's under your control via macOS settings.

Network requests MDraft makes

MDraft only makes network requests in response to actions you explicitly take:

• Remote images. If a Markdown document you open references an image by an http:// or https:// URL, MDraft fetches that image so it can display it in the Preview pane. The fetch goes directly from your Mac to the image's host.
• Web Page Import. When you use File → Import Web Page, MDraft fetches the URL you supply, extracts its readable content, and saves a Markdown document to the folder you choose. Image references in that page are downloaded to a sibling assets folder. Fetches go directly from your Mac to the page's host; no proxy, no intermediary.
• Apple‑system services. On first use of Semantic Search, macOS may download Apple's NLEmbedding language model to your Mac. That download is managed by macOS, not by MDraft. The model itself runs locally afterward.

MDraft does not contact any MDraft‑run server. Lucidex Group does not operate any backend that receives data from the app.

The marketing site (mdraft.net)

This website is hosted on Firebase Hosting. Firebase's hosting platform logs basic request data — IP address, user agent, requested path, response status — for security, rate‑limiting, and debugging purposes. Those logs are retained by Google for short periods per their hosting terms. We do not run any analytics scripts, fingerprinting, advertising, or third‑party trackers on this site.

Children

MDraft is not directed at children. It does not knowingly collect any data from anyone of any age, because it does not collect data at all.

Your rights

Because MDraft does not collect personal data, there is no information about you for us to look up, modify, delete, or sell. Apple may collect aggregate, non‑identifying purchase and crash information for App Store apps under its own privacy policy. See also our User Privacy Choices page.

Changes to this policy

If we materially change this policy, the new version will be posted at this URL with a new effective date.
