Understand the technology behind secure, self-destructing messages — and why DisappearNote is one of the safest ways to share sensitive information online in 2026.
What Is a Disappearing Note?
A disappearing note (also called self-destructing note or burn-after-reading message) is a secure way to share text online that automatically deletes itself after being viewed once or after a set time.
Perfect for:
Sharing passwords or API keys
Sending sensitive personal messages
Transmitting temporary login credentials
Any situation where you don't want a permanent record
How DisappearNote Works (Step by Step)
1. You write your message — Type anything in the box on our homepage.
2. Choose expiry time — Select 5 minutes, 1 hour, or 24 hours as a maximum lifespan.
3. Click "Create" — We generate a unique, random link and save your note temporarily on our server.
4. Share the link — Send the secret URL to your recipient (via email, chat, etc.).
5. Recipient views it once — They open the link and see the message.
6. Note self-destructs 🔥 — The message is immediately and permanently deleted from our server after viewing — gone forever.
Even if the recipient never opens it, the note auto-expires and deletes based on your chosen timer.
Is It Secure and Private?
Yes — here's why DisappearNote is safe:
No accounts or signup — Nothing to hack or track.
No logs kept — We don't store IP addresses or access records.
HTTPS encryption — All traffic is encrypted in transit.
Auto-deletion — Notes vanish after reading or expiry — no recovery possible.
Server cleanup — Background process removes any expired notes hourly.
While not end-to-end encrypted like Signal, it's far more private than email or regular messaging for one-time sensitive shares.
