Share secrets securely
Send sensitive information with end-to-end encryption. Messages self-destruct after reading - no traces, no risks.
Maximum security for confidential messages
Every feature is designed to protect your sensitive information.
End-to-End Encryption
Messages are encrypted directly in your browser. The key never reaches our servers - only the recipient can read.
Self-Destructing Messages
After reading, the message is irrevocably deleted. No copies, no backups, no traces.
Optional Password Protection
Protect your message with an additional password that you share via a separate channel.
View Limit
Set how many times the message can be read - from once up to 100 views.
Auto-Expiry
Set an expiration: after 1 hour, 24 hours, 7 or 30 days, the message is automatically deleted.
Zero Trace
Even we cannot read your messages. The decryption key is only contained in the link.
How Flaschenpost Works
Secure messaging in three simple steps.
Write Your Message
Write your confidential message and configure security options: password, view limit, and expiration date.
Create New Flaschenpost
Write a message that will be destroyed after reading.
This message will be transmitted encrypted.
Security Options
Share the password via a different channel.
How many times can the message be viewed?
Allow Replies
Recipients can reply (requires login).
Share the Link
You receive a unique link with the decryption key. Send it to the recipient - optionally share the password via a separate channel.
Message is Read
The recipient opens the link, enters the password if required, and sees the decrypted message. You get notified - then it self-destructs.
