<h1>About</h1>
<p>
<i>cryptgeon</i> is an secure, open source sharing note service inspired by
<a href="https://privnote.com"><i>PrivNote</i></a>.
</p>
<p>
<b>▶ how does it work?</b>
<br />
each note has a 512bit generated <i>id</i> that is used to retrieve the note. data is stored in memory
and never persisted to disk.
</p>
<b>▶ Features</b>
<ul>
<li>view and time constrains</li>
<li>in memory, no persistence</li>
<li>in browser encryption → server cannot decrypt contents</li>
</ul>
<p>
<b>▶ tech stack</b>
<br />
the backend is written in rust and the frontend is svelte and typescript.
<br />
you are welcomed to check & audit the
<a href="https://github.com/cupcakearmy/cryptgeon">source code</a>.
