Folder & Vault
Pick where your Markdown files live and name the subfolder where exports get written. The vault is just any iOS folder — Obsidian, Files, iCloud Drive, or third-party file providers all work.
What "vault" means here
The app uses vault as a generic name for the folder you've picked, regardless of whether you actually use Obsidian. If you do use Obsidian, point it at your Obsidian vault root. Otherwise, pick any folder — iCloud Drive's Documents/Health, an On My iPhone folder, etc.
How the picker works
Tapping the vault row opens iOS's standard document picker (UIDocumentPickerViewController). When you pick a folder, iOS returns a security-scoped URL — a long-lived handle that lets the app keep accessing the folder across launches without re-prompting. The app stores this as a bookmark in UserDefaults.
Subfolder name
After picking the vault, you're prompted to name the subfolder where exports go. The default is Health. Whatever you choose becomes the prefix for every exported file's path:
{vault}/
{subfolder}/ ← what you name here

2026-04-27-sunday.md
...You can change the subfolder later from Settings → Obsidian Vault. Existing files are not moved.
Cross-app behavior
If iOS revokes the security-scoped bookmark (rare — usually only if the underlying folder is deleted or moved), exports will start to fail. The fix is to re-pick the vault from Settings.
