Description by Aernoud Dekker Written by the developer, not by AppBrain. Click to read.
Never lose your crypto again.

20% of all Bitcoin—$250 billion—is permanently lost due to failed backups. Hardware wallet are complex only move your from digital vulnerability to physical vulnerability. Subscriptions may cost thousands over time. Social recovery depends on others.

Q-Ledger offers quantum-safe backup that lasts forever, for a one-time fee.

HOW IT WORKS

1. Import Your Private Keys
- MetaMask, Trust Wallet, Coinbase Wallet
- Type in your (hardware wallet( seed phrases
- Auto-detects any format

2. Quantum-Safe Encryption
- X-Wing / ML-KEM-768 (same as iOS 26 uses)
- Encrypted on your device
- Q-Ledger never sees your keys

3. Store Forever on Arweave
- One-time payment, permanent storage
- Thousands of independent global nodes
- Survives even if Q-Ledger shuts down

4. Recover Anytime
- Decrypt on iOS with Face ID
- Pro: Platform-independent recovery

---

WHY Q-LEDGER

* One-time fee vs. perpetual subscriptions
* Only quantum-safe crypto backup solution
* Disaster-proof: no physical backup to lose
* Zero custodians: verifiable security
* Platform independence (Pro version)
* Open encryption format
* Inheritance ready
* No account required

---

PLANS

Free version includes 1 wallet backup with quantum-safe encryption and permanent storage.

Wallet bundles available for backing up multiple keys.

Pro upgrade unlocks platform-independent recovery, multi-device iOS access, and GitHub recovery scripts for any platform.

---

SUPPORTED FORMATS

BIP39 seed phrases (12-24 words), raw hex, WIF, extended keys (BIP32/BIP44), JSON keystores (MetaMask), JWK (Arweave), QR codes, documents up to 8KB.

Auto-detect handles any format.

---

SECURITY

Your encrypted backup is publicly visible on Arweave but unreadable without your keys. This eliminates private channels where data could be intercepted. Q-Ledger never receives your encryption keys—they're stored only in iOS Keychain.

Traditional encryption (AES, RSA) will be broken by quantum computers. Q-Ledger uses X-Wing ML-KEM-768—the same post-quantum algorithm in iOS 26—protecting against future threats.

If quantum computers break Q-Ledger's encryption, they've already broken blockchain signatures. Your backup is no more vulnerable than the blockchain itself.

---

WHAT IF Q-LEDGER SHUTS DOWN?

Your wallets remain accessible. All data is on Arweave's decentralized network, not Q-Ledger servers. Standard users keep using the app. Pro users can decrypt on any platform using public GitHub recovery scripts.

---

MULTI-DEVICE ACCESS

Encryption keys sync automatically via iCloud Keychain. Sign in to a new iPhone with the same Apple ID—all wallets become accessible immediately. Pro users can also manually export for non-Apple devices.

---

Your keys, your crypto, your backup. Forever.

Download free. Back up your first wallet in 30 seconds.
