Are there other differences between iOS, Android, and Desktop Zelcore?

Answer:

While Zelcore strives for feature parity across platforms, there are some differences:

iOS-Specific Limitations:

• Swap, Buy, Sell and the NFT gallery are available (see above); on a phone the NFT gallery opens from Apps

• Biometric authentication uses fingerprint or face unlock
• Generally fewer app store restrictions

Desktop Advantages:

• Access to all experimental features

Mobile Advantages (Both iOS and Android):

• Biometric security (fingerprint, face recognition)
• Push notifications (where supported)
• Portable access to wallet
• Quick balance checks
• Easier QR code scanning for addresses

Feature availability priority:

New features typically roll out in this order:

1. Desktop (Mac/Windows/Linux)
2. Android
3. iOS (after App Store review and compliance verification)

Cross-platform features (available on all):

Can I use the same wallet on both iOS and Desktop?

Answer:

Yes, you can use the same Zelcore wallet across iOS, Android, and Desktop platforms simultaneously. Your wallet is controlled by your seed phrase, not by any specific device.

How it works:

1. Seed phrase is the key:

   • Your seed phrase controls your wallet
   • Any device with your seed phrase accesses the same wallet
   • Blockchain addresses remain the same across all platforms

2. To add your wallet to another device:

   • Install Zelcore on the new device
   • Select "Restore Wallet" or "Import Wallet"
   • Enter your seed phrase
   • Your assets, addresses, and most settings sync automatically

3. What syncs automatically:

   • All cryptocurrency balances
   • Wallet addresses (receive addresses)
   • Transaction history from blockchain
   • Asset list (which coins/tokens you've added)

4. What doesn't sync automatically:

   • Local app settings (display preferences, theme)
   • Biometric settings (device-specific)
   • App-level customizations
   • Address book (may need manual setup on each device)

Security considerations:

• Never share your seed phrase - Anyone with it controls your wallet
• Use biometric locks - Enable on each device for quick access
• Log out when needed - If sharing a computer temporarily
• Backup seed phrase securely - Don't rely on one device
• Use different passwords - If using app-level passwords on different devices

Common use case:

Many users maintain:

• iOS Zelcore for mobile access and balance checks
• Desktop Zelcore for portfolio management, FluxNodes and hardware wallets
• Same wallet, accessed from whichever device is most convenient

Important notes:

1. Simultaneous access is safe - You can have the same wallet open on multiple devices
2. Transactions made on one device appear on all devices (after blockchain confirmation)
3. No manual syncing required - Balances update automatically from blockchain
4. Platform-specific features - Some features (like hardware wallets) only work on specific platforms

Workflow example:

Morning:

• Check balance on iOS while commuting (viewing only)

Afternoon:

• Receive payment on iOS (scan QR code)

Evening:

• Swap tokens on iOS or on desktop
• Check the other device - balance updated automatically

What happens if I delete Zelcore from my iPhone?

Answer:

Deleting Zelcore from your iPhone does not delete your cryptocurrency. Your crypto is stored on the blockchain, not in the app. However, you must have your seed phrase to restore access.

What happens when you delete the app:

1. Your cryptocurrency is safe - Still on the blockchain, controlled by your seed phrase
2. App data is removed - Local settings, cached data, and app itself are deleted
3. You lose access temporarily - Until you reinstall and restore with seed phrase
4. No funds are lost - As long as you have your seed phrase backed up

Before deleting the app:

Critical: Verify you have your seed phrase saved securely

1. Open Zelcore
2. Go to Settings
3. View/export your seed phrase
4. Write it down on paper or store in secure password manager
5. Verify you've written it correctly (check spelling of each word)
6. Store in safe location

Without your seed phrase, you cannot recover your wallet after deletion.

After deleting the app:

To regain access:

1. Reinstall Zelcore from App Store
2. Open the app
3. Select "Restore Wallet" or "Import Wallet"
4. Enter your seed phrase
5. Your wallet and all balances are restored

What's restored:

• All wallet addresses
• All cryptocurrency balances
• Transaction history (from blockchain)
• Asset list

What's not restored:

• Local app settings (theme, display preferences)
• Biometric settings (must re-enable)
• App-level passwords
• Some customizations

Common scenarios:

Scenario 1: iPhone upgrade or replacement

• Get new iPhone
• Reinstall Zelcore
• Restore with seed phrase
• All assets accessible on new device

Scenario 2: App issues or bugs

• Delete Zelcore
• Reinstall fresh copy
• Restore with seed phrase
• Often fixes app-level issues

Scenario 3: Selling or giving away iPhone

• Before wiping phone: Verify seed phrase is securely backed up
• Delete Zelcore or wipe entire phone
• Your crypto remains safe on blockchain
• Restore on new device when ready

If you lost your seed phrase:

If you delete the app WITHOUT having your seed phrase backed up:

• You will lose access to your funds permanently
• There is no customer service that can recover it
• Zelcore does not store your seed phrase
• This is the nature of self-custody - you are your own bank

Prevention:

1. Backup seed phrase immediately when creating wallet
2. Test your backup by restoring on another device
3. Store securely in multiple physical locations
4. Never store seed phrase digitally (no photos, cloud storage, emails)
5. Verify you can access backup before deleting app or wiping devices

Can I transfer my Zelcore wallet from iOS to Android?

Answer:

Yes, you can easily access your Zelcore wallet on Android (or any other platform) using your seed phrase. This is the same process as using your wallet on multiple devices.

How to transfer/access wallet on Android:

1. On your iOS device (before switching):

   • Open Zelcore
   • Go to Settings
   • Securely backup your seed phrase

3. Result:

   • Same wallet addresses
   • Same balances
   • Same transaction history
   • All assets available

Important: This is not a "transfer"

You're not moving your wallet from iOS to Android. You're accessing the same wallet on a different device. Your cryptocurrency remains on the blockchain, and you can access it from any device with your seed phrase.

You can keep both:

• Keep Zelcore on iOS for everyday use
• Also use Zelcore on Android
• Both devices access the same wallet simultaneously
• Changes on one device reflect on the other

Why switch to Android?

If you're considering switching from iOS to Android Zelcore:

Android advantages:

• Feature updates may arrive sooner
• More experimental features available

What remains the same:

• All core wallet functions
• Swap, Buy and Sell
• Same security features
• Same assets and balances
• Same seed phrase controls wallet

Migration checklist:

• Backup seed phrase from iOS Zelcore securely
• Download Zelcore on Android (Google Play Store)
• Restore wallet using seed phrase
• Verify all balances match
• Test sending/receiving on Android
• Enable biometric security on Android
• Set up app-level password (if desired)
• Decide if keeping iOS version or deleting

After migration:

You can:

• Delete Zelcore from iOS if you no longer need it
• Keep both versions for redundancy
• Use Android as primary, iOS as backup viewer

Security reminder:

• Your seed phrase works on any platform
• Never share your seed phrase
• Seed phrase is the only way to recover wallet
• Keep it secure during and after migration
