Not all encrypted notepads encrypt
Plenty of note apps advertise privacy while storing your content in readable form on their servers. The lock icon protects the screen, not the data. A genuinely encrypted notepad does the cryptography in your browser, so the server receives nothing but ciphertext it cannot open.
That distinction is the single most important thing to verify. Look for a clear explanation of where encryption happens and where keys live. Vague promises like bank-level security usually mean the platform can read everything.
The checklist worth using
Before committing to any free encrypted notepad, check five things: client-side encryption, no mandatory account, offline access, markdown support for structured writing, and multi-device sync that still keeps the server blind.
ProtectedShare's encrypted notepad checks all five: it works offline-first in your browser, encrypts locally, requires zero registration, renders markdown, and syncs encrypted vaults across devices. Because it runs alongside secret sharing and .env tools, you can draft privately and share securely without switching products.
