Your security is our priority
DDisk is built with security-first principles. Your private keys never leave your device, and your files are encrypted before upload.
Security Principles
The foundational security practices that protect your assets and data.
iOS Keychain Storage
Your private keys and wallet passwords are stored in Apple's secure Keychain, protected by your device's hardware security and biometric authentication.
Client-Side Encryption
Private files are encrypted on your device before upload using ArFS-compatible cryptography. Your unencrypted data never leaves your phone.
Watch-Only Mode
Monitor any Arweave wallet without exposing private keys. Perfect for tracking balances without security risks.
Keys Never Leave Your Device
DDisk operates without a central server for key management. Your private keys are never transmitted or stored on any external server.
Network Transparency
All transactions are broadcast directly to the Arweave network. View your transaction status in real-time on any block explorer.
Open Standards
DDisk uses industry-standard formats like JWK for wallet import and ArFS for file encryption, ensuring interoperability and auditability.
Security Best Practices
Follow these recommendations to keep your wallet and files secure.
Back up your JWK file
Store a secure copy of your wallet's JWK file in a safe location. This is your only recovery method.
Remember your drive password
Your private file encryption password cannot be recovered. If lost, your encrypted files are permanently inaccessible.
Keep your device secure
Use strong device passcode and biometric authentication. Your wallet security depends on your device security.
Verify transaction addresses
Always double-check recipient addresses before sending AR. Blockchain transactions are irreversible.
Use watch-only for monitoring
For wallets you only need to monitor, use watch-only mode to avoid exposing private keys.
Keep DDisk updated
Install app updates promptly to benefit from the latest security improvements and bug fixes.
Important: Password Responsibility
DDisk cannot recover your wallet or decrypt your files without your backup and passwords. You are solely responsible for maintaining secure backups of your JWK file and remembering your drive encryption password. Lost keys or passwords result in permanent loss of access.
