Storage

massCode stores your data locally on your computer. Snippets and notes live in a Markdown Vault, so your content stays as plain Markdown files on disk instead of being locked into a cloud service or a private database format.

Markdown Vault

Why it matters

• Your data is just files. Each snippet and note is a .md file with frontmatter metadata. You can read, edit, move, and back up everything with any text editor or file manager.
• No vendor lock-in. If you stop using massCode, your content still remains readable as plain files.
• Git-friendly. Put the vault in a Git repository, track changes, and sync it through your normal workflow.
• Cloud-sync friendly. iCloud, Dropbox, Google Drive, or Syncthing all work because the vault is just a folder on disk.
• Live updates. massCode watches the vault in real time, so external file changes appear in the app automatically.

How it works

The vault mirrors your folder structure. Each folder becomes a directory on disk, and each snippet or note becomes a .md file inside it. Metadata such as language, tags, and ordering is stored in frontmatter, while .state.json stores UI state like expanded folders and sort order.

You can change the vault location in Settings → Storage.

Migration from SQLite

If you are upgrading from an older version of massCode that used SQLite storage, you can import your existing data into Markdown Vault.

• Open Settings → Storage
• Choose the import option
• Select your old massCode.db file

massCode converts your folders and snippets to Markdown Vault format.
