Glossary
Use this page when a product word is unfamiliar. The definitions are intentionally practical rather than internal.
Before you start
You do not need to memorize these terms before using Onnoir. Start with the first-session guides, then come back here when a word in the app needs context.
Terms
Vault - The local encrypted storage area that protects your Onnoir library on this device.
Recovery key - The key shown during first launch. It can unlock the library if the system keychain cannot. Onnoir cannot recover it for you.
Notebook - A container for related writing.
Chapter/page - An individual writing surface inside a notebook. The app may use both terms in different places.
Shelf - The home view for notebooks.
Cabinet - The place for images, recordings, films, documents, canvas items, and other media kept across notebooks.
Collection - A way to gather notebooks manually or by rules.
Thread - A grouping concept for related notebooks.
Today - A quick-capture space and daily running thread.
Atlas - A relationship view for notebooks, links, and backlinks.
Backlink - A connection created when one page links to another.
Cardboard - A card-based planning and arrangement space.
Snapshot - A local recovery point managed by Onnoir. Useful for recent local mistakes, but not a replacement for external backups.
.onbk - Onnoir’s encrypted backup package format. This is the restore path for a full local library.
Markdown export - A readable export of notes and related files. Useful outside Onnoir, but not the same as a full encrypted backup.
What to expect
Some views overlap. A notebook can live on the Shelf, appear in Atlas, belong to a Thread, and show up in a Collection without being copied.
Safety notes
The most important distinction is backup vs export. A .onbk backup is for restoring Onnoir. Markdown export is for readable copies outside Onnoir.
Troubleshooting
If a term in the app is not listed here, check the related workflow page first. If it is still unclear, include the exact label and where you saw it when filing a bug report or support request.
