Your passwords are only ever unlocked on your own devices. Your vault is encrypted on your iPhone and computer; our servers hold no copy of it and cannot see inside. Buy the current major version once, get free updates within it, and never create an account. YOUR VAULT STAYS WITH YOU · Encryption and decryption happen on your device; your master password is never stored or uploaded · Sync across devices through a place you choose: WebDAV, iCloud Drive, Dropbox, a local folder on your computer, or another device on the same Wi-Fi. Only the encrypted vault is transferred · Works offline for viewing, copying and adding entries BUY ONCE, NOT A SUBSCRIPTION · Pay once, use the current major version with free updates · Buy a lifetime license for 1, 3 or 5 devices in the app; owners can add devices by paying the difference · No account needed; use Restore Purchase on a new iPhone SEE WHAT AI READ Connect an AI coding assistant on your computer and decide item by item what it may read. Every read is logged: which assistant, which item, and when. After sync, the AI Access center on your iPhone shows it all, and you can revoke everything in one tap. Each item can be set to "use but can't see": the AI can use it without seeing the secret itself, and newly shared items default to this. While your computer is locked, AI requests go to your iPhone, where you can allow just that one, allow for a set time, or deny. Items you have not shared stay invisible to AI. MOVE FROM APPLE PASSWORDS In Passwords, choose Export Data to Another App → RootKey. Passwords, passkeys and verification codes are handed over by the system directly, with no server in between. SIRI AND SHORTCUTS Say "Search RootKey" or "Lock RootKey" to jump straight there. Shortcuts only open the app and never read out or return a password; you still unlock as usual. WHAT YOU GET · 19 item types: logins, credit cards, bank accounts, identity documents, Wi-Fi, servers, SSH keys and more, plus custom fields · Photograph the label on your router and the Wi-Fi name and password fill in · Keep work and personal items in separate vaults; a vault deleted by mistake can be restored from the Trash · Strong password generator with adjustable length and character sets · One-time codes (TOTP) right next to the password, filled into verification code fields automatically · Strong passwords generated and saved when you sign up; insert server addresses, tokens and card numbers into any text field · System-level autofill and passkeys · Security check: weak, reused and breached passwords, missing 2FA, expiring cards and documents · Passwords copied to the clipboard clear themselves automatically FORGOT YOUR MASTER PASSWORD? THERE IS A WAY BACK Creating a vault generates a recovery key and walks you through printing it. If you forget your master password, the key resets it without losing data. If both are lost, nobody can open the vault, including us, so keep it safe. OPEN SOURCE CRYPTO CORE Every line that touches your passwords and keys is published at github.com/bitbeam-cn/rootkey-crypto (MIT / Apache-2.0) with test vectors anyone can check. Security depends on your master password, not on the code being secret. TRIAL Try every feature free for 14 days, no sign-up. When it ends you can still view, copy and export everything; only adding and editing are limited. Support: hi@bitbeam.cn Website: rootkey.bitbeam.cn
