Deploy Cryptgeon in one click installation.
Zero-knowledge encrypted note and file sharing with self-destructing messages based on views or expiry time.
What you can build with Cryptgeon
Cryptgeon is a privacy-focused, open-source alternative to PrivNote for sharing sensitive information securely. All encryption happens client-side in the browser before data ever reaches the server, implementing a zero-knowledge architecture where even administrators cannot read message contents. Notes and files self-destruct after a configurable number of views or a time limit, ensuring sensitive data never lingers.
Self-hosting Cryptgeon on your VPS means your organization's secure communication channel runs on infrastructure you fully control — no third-party services, no data retention policies imposed by others, and complete freedom to configure expiration limits, file size caps, and access policies to match your security requirements.
Key features of Cryptgeon
Zero-Knowledge Encryption
All encryption and decryption happens in the browser, so the server never has access to plaintext content — not even administrators can read messages.
Self-Destructing Messages
Notes and files expire automatically after a set number of views or a time limit, preventing sensitive data from persisting beyond its intended use.
File Sharing Support
Share encrypted files alongside text notes, making it suitable for securely transferring credentials, keys, and confidential documents.
No Account Required
Completely anonymous sharing — recipients access content via a unique link without creating an account or providing personal information.
Password Protection
Add an extra layer of security by protecting notes with a password that recipients must enter before decryption occurs.

I'm incredibly happy with Hostinger's VPS hosting! Their uptime is consistently top-notch, keeping my site running smoothly. Whenever I've needed help, their technical support team has been quick, knowledgeable, and genuinely helpful.
Everything is smooth and great with Hostinger, the AI chat bot + human chat, if AI can't resolve your question. Oh and them VPS is just fire, no ups and downs. Thank you dev team and everyone else involved. Keep it up 🚀
Finally a VPS hosting company that does it right! Well-priced. Excellent portal that respects their users' time. Seamless backups. Good support. Reliable. Feels rock-solid.
I reached out to Hostinger support after losing access to my self-hosted n8n instance, and I couldn’t be more impressed. Hostinger Agent and Mohammad from the support team were incredibly patient and thorough.
Many thanks to Carla for helping me with this N8N upgrade on my Hostinger VPS. Professional and knowledgeable, thank you again Carla.
Hostinger VPS is absolutely outstanding. It just always works. It is always fast and stable. Never down, never crashes.
The company is doing well, I am very happy with the specific services I use through them. Not as expensive as some places with really great VPS set ups and price plans.
