Protect your Seed Phrase
without trusting anyone

CryptoSeed encrypts your cryptocurrency wallet with AES-256-GCM directly on your device — no servers, no cloud, no data collection.

100% Offline · No Servers · Android

Offline by default

Encryption and decryption happen entirely on your device. No data from your seed phrase ever travels over the internet.

AES-256-GCM + Argon2id

Authenticated encryption with a memory-hard key derivation (Argon2id, 64 MiB) — resistant to GPU- and ASIC-accelerated attacks, unlike traditional KDFs. Backups created with the previous version are still readable.

Zero sensitive persistence

Your seed phrase is never written to disk. The backup is the generated QR Code itself — physical (printed) or shared by you, with full control.

Secure memory

Sensitive data flows as CharArray/ByteArray and is zeroed immediately after use, reducing exposure in RAM.

Device protections

Detection of root, debug mode, emulator and active ADB. The app warns you about risks before any sensitive operation.

Free and Pro — same encryption

The encryption layer is identical in both versions. Pro removes word/password limits and adds extra network protections.
