## What it is
Cryptgeon is a secure, open-source note and file sharing service inspired by PrivNote, built with Rust and Svelte. Notes are encrypted client-side with AES-GCM, stored in memory only, and self-destruct after view or time limits; it ships as a self-hostable server, web app, and CLI client.

## Use cases
- share a self-destructing secret note
- send sensitive files with a one-time link
- self-host a privnote alternative
- share passwords securely with expiration
- send encrypted notes from the command line
- share secrets without the server being able to read them

## When to choose
- you need ephemeral, zero-knowledge sharing of text or files
- you want to self-host a PrivNote-like service
- you need view-count or time-limited secret links
- you want a CLI for scripted secret sharing

## When to avoid
- you need persistent, long-term document storage
- you require guaranteed view limits across multiple server instances behind shared Redis
- you need compliance-grade audit logging or access controls
