Iron Switch is an encrypted dead man's switch app for protecting crypto recovery phrases, passwords, documents, and final messages—and delivering them to trusted recipients if you stop checking in. Store your most critical information—crypto recovery phrases, passwords, documents, and final instructions—encrypted on your device before it ever leaves your phone. If you're ever unable to check in, Iron Switch securely delivers access to the people you've chosen. Everything is encrypted with AES-256 on your device. Your keys are never sent to our servers in a usable form, so no one at Iron Switch—and no one who breaches our servers—can read your vault. Only you and the recipients you designate can unlock it. HOW IT WORKS • Add your sensitive files, keys, and notes to your encrypted vault. • Choose the recipients who should receive access, plus an optional secondary verifier for added protection. • Set your check-in schedule. As long as you check in, nothing is released. • If you go silent past your window, the switch activates and your designated recipients receive secure access—exactly as you planned. BUILT FOR PEACE OF MIND • Zero-knowledge, client-side AES-256 encryption • Dead man's switch with customizable check-in intervals • Multiple recipients and an optional secondary verifier • Face ID / Touch ID app lock • Two-factor authentication (TOTP) • Offline recovery kit—export a self-contained decryptor so you're never locked out, even if our servers disappear • Delete your account and all data at any time, right from the app IMPORTANT: Iron Switch is NOT a cryptocurrency wallet or exchange. It does not buy, sell, hold, or transact cryptocurrency. It stores your private keys and recovery phrases only as client-side-encrypted text—just like any other note or document in your vault. Iron Switch includes a free plan with real protection: a secure vault, your dead man's switch, and recipient delivery. Secure your digital legacy today—so the right information reaches the right people, exactly when it's needed. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
