Password Book - Offline, encrypted password manager with secure attachments

Password Book is a fully offline password manager built for people who value privacy. All data is encrypted locally with AES-256 and never leaves your device. Unlike most password managers, Password Book lets you attach encrypted files, images, documents, and notes directly to your entries — keeping everything related to an account in one secure place. No accounts. No tracking. No cloud dependency. Just a fast, private, and modern password vault for Android.
