The Best Privnote Alternative in 2026
Privnote encrypts on their servers. EncryptedNote encrypts in your browser — we literally cannot read your data. No account required.
How EncryptedNote Compares to Privnote
| Feature | EncryptedNote | Privnote | OneTimeSecret |
|---|---|---|---|
| Encryption location | ✅ Your browser (client-side) | ❌ Their servers (server-side) | ❌ Their servers (server-side) |
| Encryption algorithm | ✅ XChaCha20-Poly1305 | ❌ Unknown / server-side | ❌ AES server-side |
| Zero-knowledge | ✅ Yes — we can't decrypt | ❌ No — server can read | ❌ No — server can read |
| No account required | ✅ Yes | ✅ Yes | ✅ Yes |
| Burn after reading | ✅ Yes | ✅ Yes | ✅ Yes |
| Max expiration | ✅ 30 days | ✅ 30 days | ✅ 30 days |
| Email notification | ✅ Yes | ✅ Yes | ❌ No |
| Password protection | ✅ Yes | ✅ Yes | ✅ Yes |
| Ads | ✅ None | ❌ Has ads | ✅ None |
| Phishing clones risk | ✅ Low | ❌ High (many fake Privnote sites) | ✅ Low |
The key difference is zero-knowledge encryption: EncryptedNote's servers only ever see ciphertext — they never hold a decryption key.
Why Privnote's Encryption Model Is a Risk
Privnote encrypts notes on their servers, which means the server generates and holds the decryption key. Before your note reaches the recipient, it passes through Privnote's infrastructure in a form that their systems can technically read. This is fundamentally different from client-side encryption, where the key never leaves your device.
This server-side model has had real consequences. Dozens of convincing fake “Privnote clone” phishing sites have appeared over the years, intercepting notes because server-side encryption is easy to mimic. Visitors land on a lookalike site, submit their secret, and the attacker reads it before forwarding it along. The recipient never knows anything went wrong.
EncryptedNote takes a different approach. Encryption happens entirely in your browser using XChaCha20-Poly1305 before anything is transmitted. The decryption key is embedded in the URL fragment (the part after #), which browsers never send to servers. Our servers only ever receive encrypted ciphertext — we see only gibberish even if we tried to read it.
How EncryptedNote Works
✍️ 1. Write
Type your secret in the editor. Your note is encrypted in your browser before it ever leaves your device.
🔗 2. Share
Get an encrypted link and send it to your recipient through any channel. The decryption key lives only in the URL fragment — our servers never see it.
🗑️ 3. Destroy
The note self-destructs after reading. Gone forever — no traces on our servers.

Stronger Encryption Than Most Alternatives
Most alternatives use AES-256. EncryptedNote uses XChaCha20-Poly1305 — a modern authenticated encryption algorithm with a 192-bit nonce, compared to AES-GCM's 96-bit nonce. The longer nonce eliminates nonce-reuse vulnerabilities that can silently break security at scale, without requiring any special hardware acceleration. XChaCha20 is the same algorithm used by WireGuard VPN and is recommended by modern cryptographers for software-based encryption. See our full security details →
Frequently Asked Questions
Is EncryptedNote really safer than Privnote?
Yes, for one key reason: encryption happens in your browser, not on our servers. Privnote's server holds the key and can technically read your note. With EncryptedNote, the decryption key is in the URL fragment and never reaches our servers — we literally cannot read your content. For more detail, see how to securely share passwords.
Do I need an account?
No. EncryptedNote requires zero signup. Write a note, get a link, share it. That's it.
What happens after the recipient reads my note?
Notes self-destruct automatically — either after the recipient reads it (burn after reading) or after your chosen time limit expires, whichever comes first. Once deleted, it cannot be recovered.
Is EncryptedNote free?
Yes, completely free. No ads, no account, no limits on the core feature.
What encryption does EncryptedNote use?
XChaCha20-Poly1305 — client-side, in your browser. The decryption key is embedded in the URL fragment and never sent to our servers. See our Security page for full technical details.
