          SECURE STORAGE - MOBILE DEVICE INSTRUCTIONS
======================================================================

IMPORTANT: Mobile access has limitations compared to desktop.
Read carefully to understand what's possible on your device.

======================================================================
ANDROID DEVICES
======================================================================

REQUIREMENTS:
  • Android 5.0 or newer
  • EDS (Encrypted Data Store) app - REQUIRED
  • USB OTG adapter (to connect USB device to phone)
  • File manager app (most phones have one built-in)

REQUIRED APP:
  • EDS Lite (Free & Open Source)
  • Google Play: https://play.google.com/store/apps/details?id=com.sovworks.eds.android
  • Direct link if Google Play doesn't work:
    https://play.google.com/store/apps/details?id=com.sovworks.projecteds

----------------------------------------------------------------------
SETUP: Using EDS Lite (RECOMMENDED)
----------------------------------------------------------------------

Step 1: Install EDS Lite
        • Open Google Play Store
        • Search for "EDS Lite" or "EDS (Encrypted Data Store)"
        • Install the app (it's FREE)
        • Or use the direct link above

Step 2: Connect your USB device
        • Connect USB device using OTG adapter
        • Android should show "USB device connected" notification

Step 3: Open EDS Lite app
        • Tap "Open container"
        • Navigate to your USB device
        • Look for the partition WITHOUT a filesystem/label
        • Select the encrypted partition

Step 4: Enter password
        • Select encryption: VeraCrypt
        • Enter your password
        • For PIM: enter 2000 or 5000 (whatever you set)
        • Tap "OK"

Step 5: Access your files
        • Files will appear in EDS Lite
        • You can view, copy, or share files
        • Some apps can open files directly from EDS

IMPORTANT - Safely Close:
        • Tap "Close container" when done
        • Wait for confirmation before unplugging
        • Only then remove USB device

----------------------------------------------------------------------
ALTERNATIVE: VeraCrypt for Android (Advanced Users)
----------------------------------------------------------------------

ℹ️ NOTE: EDS Lite (above) is easier to use and recommended.
   Only use VeraCrypt if you're familiar with it.

Step 1: Install VeraCrypt for Android
        • Download from: https://github.com/veracrypt/veracrypt
        • Or install from F-Droid store
        • Enable "Unknown sources" if needed

Step 2-5: Follow similar steps as EDS Lite above
        • The interface is similar to desktop VeraCrypt
        • Process is the same: select partition, enter password, mount

======================================================================
iOS DEVICES (iPhone/iPad)
======================================================================

✅ SOLUTION: Crypto Disks App (Paid)

RECOMMENDED APP:
  • Crypto Disks - Store Private Files Securely
  • App Store: https://apps.apple.com/us/app/crypto-disks-store-private/id889549308
  • Price: ~$4.99 (one-time purchase)
  • Supports VeraCrypt containers!

----------------------------------------------------------------------
SETUP: Using Crypto Disks on iOS
----------------------------------------------------------------------

Step 1: Purchase and Install Crypto Disks
        • Open App Store on your iPhone/iPad
        • Search for "Crypto Disks"
        • Or use the direct link above
        • Purchase and install (~$4.99)

Step 2: Transfer Encrypted Container
        ⚠️ LIMITATION: iOS doesn't support direct USB access like Android

        You have two options:

        OPTION A: Copy via Computer (Easier)
        1. Connect USB device to your Mac/PC
        2. Mount the encrypted partition with VeraCrypt
        3. Create a smaller VeraCrypt container file inside
        4. Transfer that container to your iPhone via:
           - AirDrop (Mac to iPhone)
           - iCloud Drive
           - iTunes File Sharing
        5. Open in Crypto Disks app

        OPTION B: Use Wi-Fi File Transfer
        1. Use Crypto Disks' built-in file transfer
        2. Transfer container file from computer
        3. Open in app

Step 3: Mount in Crypto Disks App
        • Open Crypto Disks app
        • Select "Add Disk Image"
        • Choose your transferred container
        • Enter password and PIM
        • Access your files

⚠️ IMPORTANT iOS LIMITATIONS:
   • Cannot directly mount USB partition (Apple restriction)
   • Must use container FILES, not raw partitions
   • Requires copying/transferring container to iPhone
   • Best for occasional access, not primary use

----------------------------------------------------------------------
iOS WORKAROUND: Emergency Access Only
----------------------------------------------------------------------

If you don't want to pay for Crypto Disks, here are free alternatives:

Option A: Use a Computer as Bridge
        1. Mount the encrypted storage on your Mac/PC
        2. Copy files you need to iCloud or Files app
        3. Access those files from your iPhone
        4. Delete copies when done (IMPORTANT for security!)

Option B: Use Remote Access
        1. Mount encrypted storage on your home computer
        2. Set up secure remote access (VPN + file sharing)
        3. Access files remotely from iPhone
        4. More complex but maintains security

Option C: Take Photos of Documents
        1. If you just need to VIEW travel docs in emergency
        2. Take photos/screenshots on computer
        3. Store in encrypted note app (Apple Notes with lock)
        4. Delete after trip

NOTE: These workarounds compromise security slightly.
      Crypto Disks app is the most secure iOS solution.

IMPORTANT SECURITY NOTES FOR MOBILE
======================================================================

⚠ Screen Lock
   • Always have a PIN/password on your phone
   • If someone steals your phone while storage is mounted,
     they can access your files

⚠ App Permissions
   • Only grant necessary permissions to encryption apps
   • Be cautious with "file access" permissions

⚠ Public WiFi
   • Don't use public WiFi when accessing sensitive files
   • Or use a VPN if you must

⚠ Battery Concerns
   • Don't let your phone die while storage is mounted
   • Always properly close/dismount before battery runs out

⚠ Background Apps
   • Close the encryption app properly when done
   • Don't just switch to another app
   • Storage might stay mounted in background

⚠ Phone Updates
   • Close encrypted storage before major OS updates
   • Updates might interrupt and cause corruption

======================================================================
TROUBLESHOOTING - ANDROID
======================================================================

"Cannot find USB device"
  • Try a different OTG adapter
  • Check if your phone supports USB OTG
  • Some phones need USB settings changed (File Transfer mode)

"Wrong password" (but password is correct)
  • Make sure you selected "VeraCrypt" as encryption type
  • Verify PIM value (2000 or 5000)
  • Some apps don't support all VeraCrypt settings

"App crashes when mounting"
  • Try a different encryption app (EDS vs VeraCrypt)
  • Check if partition is already mounted
  • Restart phone and try again

"Can't edit files, only view"
  • This is normal for some apps
  • Copy file to phone storage
  • Edit it there
  • Copy back when done

"Storage disconnected unexpectedly"
  • Check USB connection
  • Some phones cut power to USB to save battery
  • Disable battery optimization for the encryption app

======================================================================
LIMITATIONS OF MOBILE ACCESS
======================================================================

Things that DON'T work well on mobile:
  ✗ Editing large files directly on encrypted storage
  ✗ Running programs/apps from encrypted storage
  ✗ Fast file operations (mobile is slower than desktop)
  ✗ iOS access (not supported at all)

Things that WORK WELL on mobile:
  ✓ Viewing documents (PDFs, photos, etc.)
  ✓ Copying individual files to phone
  ✓ Sharing files to other apps
  ✓ Emergency access when no computer available
  ✓ Quick lookup of information

RECOMMENDATION:
  Use mobile access for emergencies and viewing only.
  Use desktop (Linux/Windows) for actual file management.
