Results live in page memory until you leave or clear. Favourites/history do not save password fields unless you explicitly store them in Vault.
When applicable, tools rely on Web Crypto or well-known libraries. Read on-page notes for exact algorithms (SHA-256, bcrypt-style notes, etc.).
After load, crypto helpers typically work offline. Confirm network independence for your threat model.
Browser CSPRNG (crypto.getRandomValues) powers secure generators when the tool states so.
Treat generated secrets like passwords - share only through approved password managers, never chat apps.
