Prism Password Manager

Prism is a local-first, end-to-end encrypted security manager for everything you need to keep private: passwords, payment cards, environment secrets (.env and .key files), and secret notes. Your vault is a single encrypted file that lives on your device. Prism never sees your passwords, your master password, or the contents of your vault, because encryption and decryption happen entirely on your device. KEY FEATURES - End-to-end encryption: your vault is encrypted locally, and nothing is ever readable by Prism. - Passwords, cards, secrets & notes: store login credentials, payment cards, .env-style environment secrets, SSH keys, GPG keys, etc., and free-form secret notes, all organized with custom categories. - Biometric unlock: unlock your vault quickly and securely using your device's fingerprint sensor. - Password generator: create strong, unique passwords in a tap. - Security audit: review your vault for weak or reused passwords. - Breach checking: check whether your passwords have appeared in known data breaches, using a privacy-preserving method that never sends your full password anywhere. - Optional Google Drive sync: back up and sync your encrypted vault to your own Google Drive, stored in a private, app-only folder. It is off by default and entirely your choice. - Favicon lookup: automatically fetch website icons to make your vault easier to browse (optional, can be disabled). - No account required: Prism works fully offline, with no sign-up and no server-side account. - No ads, no telemetry: Prism does not display ads and does not track your usage. - Multilingual: available in multiple languages. WHY PRISM? Prism was built around a simple idea: your sensitive data should stay yours. There's no cloud database holding your secrets, no analytics tracking your behavior, and no ads funded by your data. Optional features like Google Drive sync and breach checking are opt-in, and designed so that even when enabled, Prism learns as little about you as possible. Whether you're a professional managing dozens of accounts and API secrets, or someone who simply wants a safer way to store passwords and payment cards, Prism gives you full control over your data: on your device, under your key. We're actively working on Prism and welcome your feedback as we continue to improve it.
