Message privately. Truly.
Pénombre encrypts every message, photo, and call end-to-end — without ever asking for a phone number, an email, or a password. Your identity is generated on, and stays on, your device.
- No phone number
- No email
- No password
- Encrypted on-device
Built so your privacy stays private
No account, ever
On first launch, Pénombre generates a cryptographic identity directly on your device. Nothing to create, nothing to remember, nothing to confirm by email.
End-to-end encrypted
Messages, photos, and calls are encrypted on your device and decrypted only on the recipient's. The relay that routes your messages can never read them.
Living fingerprint
Verify any contact in person with a visual seal generated from both your keys — proof that no one has intercepted the conversation.
Disappearing messages
Set your messages to vanish after 1 minute, 1 hour, or 24 hours — per conversation.
Per-chat lock code
Protect a specific conversation with its own code, separate from your device lock, so it stays hidden even if someone else opens the app.
Encrypted groups
Create fully encrypted group chats, with the same total absence of any required account.
Voice & video calls
Encrypted peer-to-peer calls, with an optional mode that relays media to protect your IP address.
Import your history
Bring your old WhatsApp or Telegram conversations over — parsed entirely on your device, nothing is uploaded.
In your language
Available in French, English, Spanish, and Hindi, with automatic detection based on your device.
Three steps. Zero forms.
Open the app
Your identity — a key pair — is generated on your device instantly. No sign-up.
Share your key
Have the person you want to talk to scan your QR code, or paste their public key. That's the entire "add a contact" process.
Chat, privately
Every message is encrypted before it even leaves your device. Lock a conversation, make it disappear, verify your contact — it's all in your hands.
Reply to customers, even while away
Run one or more businesses from the same app. Assign each customer to a business profile and let Pénombre reply on your behalf — using simple templates or an AI you configure yourself — while you're busy elsewhere.
- One profile per business, each with its own replies
- Keyword-based replies, 100% on-device, or AI-powered
- Customers never see the difference — just a quick reply
Your privacy isn't for sale.
