Sigilock - Showcase Project

Sigilock is a private photo vault for iPhone and Android. You draw a pattern, your sigil, and each sigil opens its own encrypted vault for photos, videos, files and notes. There is no account, no ads, no analytics and no tracking, and it works fully offline. Everything is encrypted on the phone with AES-256-GCM, with a separate key for every file. Your sigil is combined with a device secret and stretched with Argon2id, so every guess costs about 0.7 seconds of work. Nothing in the app lists your vaults or says which pattern opens what. It is built for the moment someone asks to see your phone: keep a harmless decoy vault, or use a duress sigil that opens a believable vault and quietly removes every other pattern. Each vault has its own 12-word recovery phrase, and encrypted backups can go to your own iCloud or Google Drive. Key features: sigil pattern lock with one vault per pattern, decoy vaults, duress mode, AES-256-GCM encryption with a key for every file, 12-word recovery phrase per vault, intruder log, hidden trail, secure camera that skips the camera roll, encrypted notes, privacy shield (screenshot and recording blocking, app switcher seal, auto-lock), expiring shared vaults (Premium), encrypted backup to your own iCloud or Google Drive. Pricing: Freemium. Free includes every privacy feature, 2 vaults and up to 25 items each. Premium is EUR 1.99/week, EUR 22.99/year, or EUR 49 lifetime (unlimited vaults and items, shared vaults). Platforms: iOS, Android. Languages: English, French, German, Spanish. Launching soon on iPhone and Android. Contact: hello@sigilock.app
