🔒 Private Vault & Toolkit
Your private data, kept private
Unlike every other tool on this site, these handle your real, sensitive data - so they do it the only safe way: 100% locally. Nothing you type or store here is ever sent to a server (there isn't one). Stored data is encrypted with a master password using AES-256, right in your browser.
How the privacy works: Your master password derives an encryption key (PBKDF2, 150,000 iterations) that never leaves the page. Vault items are encrypted with AES-256-GCM and saved only in this browser's local storage. If you forget your master password, the data cannot be recovered - not by us, because we never have it.
Three kinds of private tools
- 🔐 Encrypt & Encode - AES text encryption, ciphers (Caesar, Vigenère, Atbash, ROT13), Base64/32/hex/binary, Morse, secure hashes (real SHA), HMAC, a JWT decoder, a password-strength meter, and a secret splitter.
- 🗄️ Local Vault - encrypted stores for passwords, secure notes, API keys, Wi-Fi passwords, licenses, cards, PINs, 2FA recovery codes, contacts, bookmarks, a journal, to-dos, accounts and document IDs.
- 🧮 Private Calculators - salary take-home, net worth, loans, budgets, retirement, debt payoff, BMI/TDEE and more - the kind of numbers you'd never want to type into a random website.
An honest note on the security model: Browser-local encryption is great for keeping data off the cloud and off our (non-existent) servers. It is not a full replacement for a dedicated, audited password manager: anyone with access to your unlocked device can read your screen, and browser storage can be cleared. Use a strong, unique master password, lock the vault when you step away, and keep a separate backup of anything irreplaceable.
