WallKey: SwapFriend'sWallpaper

[WallKey: Real-time Interaction Across Screens]

WallKey is a real-time desktop interaction app for friends, family, and partners. Turn your phone screen into a bridge to connect your lives. Share your unique "Key" to start a one-of-a-kind interactive experience.

I. App Features
WallKey supports full interaction across background and foreground. Even if a friend's phone is on standby, you can remotely update their wallpaper, lock screen, or send instant surprises to desktop widgets. Deliver your mood and scenery directly to where they look most often.

II. Security & Permissions
Privacy is our priority. In "Settings," you can flexibly adjust:
1. General Permissions: Decide who can change your wallpaper, lock screen, or widget content.
2. Notifications: Choose to receive alerts when your content is updated.
3. Individual Friend Settings: Enable specific access for different friends (e.g., allow wallpaper changes but not lock screen).
4. Window Authorization: Grant independent access to specific desktop widgets.
5. Auto-Authorization: Enable "Auto-add new friends" to let new connections start interacting immediately.

III. What is a WK Window?
A WK Window is a desktop widget for Android. It acts as a "window" opened by your friend, showing real-time glimpses of their life. Manage these via "Manage WK Windows." Once added to the home screen, images sent by friends appear instantly.

IV. How to Add Friends
Connecting is easy:
1. View Key: Find your unique Key in "Settings."
2. Share Key: Copy your Key or show your QR Code for friends to scan.
3. Add Friend: On the "Friends" page, tap the icon to enter a Key or scan a QR Code.

V. Changing Content & Sending Moods
Status icons next to avatars show available items (Wallpaper, Lock Screen, or Widget).
1. Change Wallpaper: Tap an avatar to open the menu and send a surprise instantly.
2. Send Mood Cards: Select "Send Mood" to pick a background and add a message. Your custom card will be pushed directly to their screen.

VI. History & Restore Gallery
1. History: Automatically records all interactions. Browse past moments and download original images.
2. Restore Gallery: Add favorite images to your gallery. If a friend changes your wallpaper, restore your preferred look with one click.
