About ArkWarden.app and mlsql

In their own words, as submitted to SaaSHub.

ArkWarden.app
mlsql

ArkWarden is an on-device encrypted vault for iPhone that stores photos, videos, documents, and audio. Most vault apps hide files behind a lock screen without actually encrypting them, or ask you to trust closed-source claims about how their encryption works. ArkWarden takes a different approach....

Features and specs

What each product offers, as listed by its team.

ArkWarden.app 8 features
mlsql 0 features
  • Real encryption
    Every file is encrypted individually using AES-256-GCM through Apple's CryptoKit. Without your pattern or recovery phrase, the data is unreadable. No one can access your files without one of them.
  • Pattern unlock
    Draw a pattern instead of typing a password. Your pattern is part of the encryption itself, not just a way to open the app.
  • Two-factor authentication
    Add another authentication step with Face ID, a 6-digit PIN, or a YubiKey over NFC.
  • Wing: a second vault with a second pattern
    A different pattern opens a different vault with its own files and appearance. Keep your main vault hidden when you need to give someone your unlocked phone.
  • Recovery phrase
    A recovery phrase from the BIP-39 wordlist, 12 or 24 words, helps you regain access if you forget your pattern. It is shown once and stored only by you.
  • On-device privacy
    No account. No server. No cloud sync. No file analytics. Your files stay on your device and under your control.
  • Backup & Restore
    Back up your vault to iCloud or export it as a file. Every backup is encrypted with your recovery phrase before it leaves your phone. Off by default.
  • Folders and categories
    Create folders within each category. Drag files into folders or import them directly into folders, and keep your vault organized as it grows.

Questions & Answers

As answered by people managing ArkWarden.app and mlsql.

Who are some of the biggest customers of your product?

ArkWarden.app's answer

ArkWarden is a consumer app for individual use, not a business tool with named accounts. Its users are people who care about their privacy and want their files encrypted on their own device rather than trusted to a company.

What makes your product unique?

ArkWarden.app's answer

ArkWarden is an on-device encrypted vault for photos, videos, documents, and audio. Your pattern derives the key that unlocks your encryption key. There is no account and no ArkWarden server. The encryption path is open source. You also get Face ID, PIN and YubiKey over NFC as optional 2FA and unlimited folders to organise your files.

Why should a person choose your product over its competitors?

ArkWarden.app's answer

Most vault apps hide files behind a lock screen without encrypting them, or ask you to trust closed-source claims about encryption. ArkWarden encrypts every file on your device with a key derived from the pattern you draw, and the encryption code is public so you can verify it.

How would you describe the primary audience of your product?

ArkWarden.app's answer

Privacy-minded iPhone users who keep sensitive personal or work files on their phone and do not trust cloud vaults or "hidden" albums. That includes people who share a device, travel, handle client documents, or simply want private media and documents encrypted and offline by default.

What's the story behind your product?

ArkWarden.app's answer

I wanted a vault for myself: private files encrypted on my own device, not sitting in a cloud behind an account I could not inspect. Existing options asked me to trust a server and a business that had reasons to access data. So I built the opposite: pattern-derived keys, no account, no server, funded only by subscription or lifetime purchase, with no ads and no data selling.

Which are the primary technologies used for building your product?

ArkWarden.app's answer

Native iOS. Apple CryptoKit and Secure Enclave-backed Keychain. AES-256-GCM and ChaCha20-Poly1305 for encryption. PBKDF2 (NIST SP 800-132, 600,000 iterations) for key derivation. The BIP-39 wordlist for the recovery phrase. FIDO2 / WebAuthn for YubiKey over NFC. Fully on-device architecture, with optional backup only as ciphertext you control. Encryption-related code is published open source on GitHub.
