VaultNote is the ultimate offline note-taking app with AES encryption, local storage (IndexedDB), and full privacy. Organize notes in a flexible tree structure, enhance productivity, and securely store your knowledge on your device.





Iβm Hong π, the creator behind VaultNote App.
VaultNote came from a simple frustration: most note-taking apps force you to choose between convenience β‘, privacy π, and ownership ποΈ.
Some apps are powerful πͺ but cloud-first βοΈ and account-dependent. Others are privacy-focused π, but require installing desktop software π», managing files π, or trusting external sync services π. I wanted something that worked instantly β‘, offline π΄, and without giving up control of my data π‘οΈ.
VaultNote app introduces a different recipe for note-taking π:
100% local-first β everything runs entirely in the browser π
No login, no server, no tracking π«
All data stored in IndexedDB / LocalStorage πΎ
AES encryption locally π with a single master password
Your data never leaves your device π
VaultNote app is super simple to use β¨: access https://vaultnote.saposs.com, enter your master password π to sign up, and start writing notes βοΈ. The master password is used to encrypt/decrypt all data in IndexedDB, so you must remember it π§ .
All data in IndexedDB is encrypted with AES π using your master password. This makes offline attacks on stolen data extremely difficult if your password is strong πͺ. Note that encryption does not protect against attacks that capture your password π or execute malicious code in the browser π.
The goal was to make privacy the default β , not a setting you have to enable or pay extra for π΅.
As development progressed, the focus stayed minimal π―: a solid offline editor π, safe autosave πΎ, history versioning β³, encrypted export/import π¦, and reliable offline performance β‘.
VaultNote isnβt trying to replace every note app π«. Itβs built for people who want fast β‘, offline π΄, private π notes they truly own ποΈ, without installing anything π» or trusting a cloud βοΈ.
