Understanding the Vault Interface

UltraLocked's interface is split into three top-level tabs at the bottom of the screen. Each tab has its own focused toolbar.

1. The Tab Bar

At the bottom of the screen you'll always see three tabs:

• Vault — your encrypted files (notes, photos, videos, audio, documents). This is where you spend most of your time.
• Secrets — the dedicated crypto secrets vault for seed phrases and private keys. Separate from your file vault, with its own list and add controls.
• Settings — security configuration, subscription status, cross-device transfer (Encrypted Export/Import and QR Receive), preferences, and emergency protocols.

The Settings tab is always visible. Hiding it would be suspicious, so we keep it where any user expects to find it.

2. The Vault Tab

Your file vault is a grid (or list) of every encrypted item.

• Top right — view toggle: Tap the grid/list icon to switch between layouts. The icon shows the mode you'd switch to on tap (grid icon while in list view, and vice versa).
• Top right — sort & filter: Tap the three-line icon to open the menu. You can sort by Date Added, Date Modified, Name, or Size; flip direction; and filter by All / Images / Documents / Audio / Videos / Notes. Selections persist across launches.
• Bottom right — Add (FAB): The floating + button opens a menu with New Note, Take Photo or Video, and Record Audio. This is the only entry point for creating items, so it's prominent and one tap away.
• Tap an item: opens the appropriate viewer (rich-text editor, image viewer, video player, audio player, or PDF viewer).

3. File Items

Each item in the vault represents a securely encrypted file:

• Thumbnail — a small, blurred preview for visual content; an icon for documents and audio.
• Title — the file name. Edit it inline by opening the item.
• Self-destruct timer — if the item has a TTL, the remaining time is shown and counts down. When zero, it's securely deleted.

4. The Secrets Tab

A separate, isolated vault for cryptocurrency seed phrases and private keys. It has its own list, its own add button, and its own settings (under Settings → Crypto Secrets). See Storing Crypto Secrets for details.

5. The Settings Tab

Settings sections in order:

1. Preferences — Keep screen awake, default self-destruct timer, authentication strength, PIN management.
2. Subscription — your current plan (Free, Premium, Trial, or Debug Bypass) with renewal date when available.
3. Crypto Secrets — preferences for the secrets vault (reveal delays, duress behavior).
4. Data — cross-device transfer: Encrypted Export, Import .ultralocked file, and Receive via QR.
5. Mission Control — duress code, dead man's switch, multi-factor auth, emergency protocols.
6. Help & Resources — these articles, the whitepaper, terms, privacy.
7. Emergency — destructive actions: wipe vault, complete cleanup, factory reset.
