NexusVault is a private, encrypted home for the sensitive information you'd rather not write down anywhere — passwords, payment cards, bank accounts, IDs, software licenses, secure notes, and more. Everything lives in your own iCloud, locked behind your master password. More than a password manager. Built for everything that matters. WHAT YOU CAN STORE • Logins & Passwords — for websites, apps, devices, and servers • Secure Notes — anything you don't want in plain text • Payment Cards — credit and debit, with security codes and PINs • Bank Accounts — account numbers, SWIFT codes, balances • Software Licenses — keys, registrations, purchase records • Personal IDs — passports and driver's licenses with expiry tracking • Domains — registrar info and renewal dates • Custom Fields — extend any item with the fields you need PRIVACY BY DESIGN NexusVault was built around one rule: your secrets should belong to you alone. • AES-256 end-to-end encryption — every field encrypted on your device • Zero-knowledge architecture — your master password never leaves your phone • Your iCloud, not our servers — there's nothing on our end to breach • PBKDF2 key derivation with brute-force lockout protection • Hidden content on app switcher and when backgrounded • No tracking, no analytics, no ads KEY FEATURES • iCloud Sync (Optional) Sync seamlessly across iPhone and iPad through your own iCloud. Or stay fully offline — it's your choice. • Face ID & Touch ID Unlock instantly with biometrics. • Multiple Vaults Separate work, personal, and family information into independent vaults with custom names and icons. • Smart Organization Group by category, favorite items for quick access, sort and filter, and search instantly across your vault. • Encrypted Backup & Export Export your entire vault to a password-protected backup file. Restore on any device with your password. • Auto-Lock Lock immediately, after a minute, or on a schedule you set. WHY NEXUSVAULT? Most "password managers" ask you to trust their servers. NexusVault doesn't have any. Your iCloud, your device, your keys — that's it. Whether you're securing a handful of logins or hundreds of cards, IDs, licenses, and notes, NexusVault gives them a private, beautifully designed home built natively for iOS.
