Vault keeps protected material on your backend.

Vault is the place AiMANAC stores documents and attachments that should stay behind authenticated access. Text gets read on demand. Attachments get downloaded only when you ask. Desktop tools talk to the same authenticated backend as the iPhone — no public relays, no signed URLs.

Not the same as Personal Stash Lite. If you want long PDFs or pasted articles turned into study cards on the phone, read the Personal Stash Lite manual — on-device Import, Library, Review, and model choices. Vault is only about AiMANAC’s backend-held protected library; the two solve different jobs.

Each page covers one aspect of how Vault behaves. Read the basics first if you're new to it.

• Protected Copy vs Working CopyTwo copies, different jobs — protected stays in Vault, working copy goes to Library.
• Text DocumentsOpen protected text only when you need it; the iPhone doesn't mirror it.
• AttachmentsPDFs, images, Office, ZIP — stay on the backend until you ask for a copy.
• Desktop and plug-insDesktop tools use the same authenticated API. No public relays or signed URLs.

The Vault passphrase cannot be changed later.

When you turn the Vault on, the passphrase you set is permanent — there is no rekey or "change passphrase" yet. Save it in your password manager before you continue setup.

AiMANAC offers backup options during setup (the app shows them right after the Vault turns on) — configure them. If the passphrase is lost without backup options in place, the only path back is a manual export, reset, and re-import of your protected library. Passphrase rotation is on the roadmap but has not shipped; this page will say so plainly when it does.
