Your privacy, in plain text.
Rule Markdown privacy policy.
Last updated: September 30, 2026
Rule Markdown is a Markdown reader for Mac, iPhone, and iPad from Rule Mobile LLC. This policy covers the native app and its included preview extensions.
Your documents
Markdown is processed on your device. Rule Markdown does not upload your documents, their contents, or your reading activity to Rule Mobile. The app has no account system, advertising, tracking, or analytics SDK. It does not process payment information.
The app reads files you choose and leaves the originals unchanged. It can read supported local images and linked notes inside folders you allow. Remote images and executable document content are blocked. The preview extensions also render locally.
Information saved on your device
Rule Markdown saves your theme, text size, code-line-number preference, and recent-file settings on your device. It also saves bookmarks for folders you have allowed. When Remember recent files is on, the app saves up to 50 recent-file references containing filenames, file locations, and file-access bookmarks. Recent-file cards use document icons; the app does not save document contents or preview thumbnails for that history. On Mac, it also adds those files to Rule Markdown's File > Open Recent menu. A file-access bookmark is a system reference that helps the app reopen a file or folder with your permission.
These settings and references are not sent to Rule Mobile. Your device, backup service, or document provider may separately store or back up files and app settings according to your configuration and that service's terms.
Your choices
The eye button hides the recent-file list in the sidebar and shows it again when selected a second time. It does not clear the list or stop the app from saving history. On Mac, File > Open Recent remains available. Show Recent Files in Sidebar in Settings controls the same visual preference.
In Settings, turn off Remember recent files to clear Rule Markdown's saved recent-file entries and their file-access bookmarks, clear its File > Open Recent list on Mac, and stop saving new entries. Turning it back on allows files you open afterward to be remembered; it does not restore the cleared list.
Clear Recent Files removes the app's current recent-file entries and their file-access bookmarks, including its File > Open Recent list on Mac. It leaves the Remember recent files setting unchanged, so future files can be remembered when that setting is on.
These controls do not delete your documents or erase separate histories kept by Files, other apps, or the operating system. Already opened documents retain their existing access until you close them. Saved folder access is separate: open Settings > File Access and choose Forget Access for a folder to remove its saved permission.
You can change your reading preferences in Reading Options. Removing the app may remove its local settings, depending on your platform and backup settings; your original documents remain in the locations where you stored them.
Clipboard, sharing, and external links
When you choose Copy Document, Rule Markdown puts plain text, formatted text, or HTML on the system clipboard, according to your choice. Copy on a code block copies that code. The normal Copy action can copy selected text. The operating system and apps you paste into control how that content is used. System features such as Universal Clipboard may transfer copied content according to your device settings.
When you share a document, print it, or save a PDF, the system and destination you choose handle that content. In the main app, following a web or email link opens the appropriate external app. The destination's privacy policy then applies.
Cloud documents and Apple services
Files selected from iCloud Drive or another document provider may need to download before opening. Rule Markdown does not run its own document-sync service. Your provider controls its storage and syncing. Apple may process App Store, purchase, or diagnostic information under Apple's policies and your device settings; Rule Markdown does not add its own diagnostic upload service.
