Iron Lock is the companion app for your Iron Lock smart safe. Set it up in minutes, then lock, unlock, and manage your safe right from your phone. CONTROL FROM ANYWHERE • Lock and unlock your safe from the app. • Open with your fingerprint, a keypad code, the app, or your mechanical backup key — whatever's easiest in the moment. • Your safe stays usable even without the internet: the keypad, enrolled fingerprints, and mechanical key keep working on the safe itself. PEOPLE YOU TRUST • Add members and give each person their own keypad code. • Enroll fingerprints for quick, personal access. • Remove access any time. STAY IN THE KNOW • See a clear activity history of locks and unlocks. • Organize multiple safes into rooms. • Set auto-lock so your safe re-locks on its own. BUILT-IN HELP • Maya, our in-app assistant, answers setup and how-to questions. Maya is an AI assistant and its replies may be inaccurate — verify anything important. PRIVACY BY DESIGN • Your fingerprints never leave the safe. Fingerprint data is created and stored only on the safe's own sensor — never sent to the app, our servers, or us. • We don't sell your personal information, use advertising SDKs, or track you. • Delete your account and data anytime from Settings → Account → Delete Account. IMPORTANT No lock, safe, or app is infallible. Iron Lock helps deter unauthorized access and gives you convenient control and visibility — it is not a monitored alarm or emergency service, and it does not summon help. Keep your codes private, your firmware updated, and your mechanical key in a safe place. Requires an Iron Lock smart safe. Available in the United States. Questions? info@shopironlock.com
