Secure Notes Vault – Zero-knowledge, encrypted alternative to Evernote & Notion

Summary: Secure Notes Vault is a zero-knowledge workspace that encrypts all data locally using AES-256-GCM and a Master Key derived from 600,000 PBKDF2 iterations. It offers rich-text editing, encrypted Kanban boards, and secure voice notes, ensuring no one but the user can access the content. Data is synced across devices with no backdoors or server-side decryption.

What it does

It encrypts notes, Kanban boards, and voice recordings in the browser before syncing encrypted data to the server. The Master Key is generated from the user’s password, and only ciphertext is stored remotely.

Who it's for

Users needing a privacy-focused note-taking solution for sensitive information like work configurations, API keys, and personal journals.

Why it matters

It eliminates risks of data exposure by preventing anyone, including the provider, from accessing user content through strict zero-knowledge encryption.
