What We Build

Korerium makes a focused suite of privacy and security tools. No bloat, no bundles, no software you did not ask for. Each product solves one problem completely.

VaultDrop
A password protects access to a file. Encryption protects the file itself. VaultDrop encrypts locally using AES-256.

The Way We Build

These are not marketing promises. They are the decisions we made before writing a single line of code.
Local-First, Always
Every process runs on your machine. No file touches a server. Nothing about how you use the software is ever transmitted anywhere. Your email at purchase is used solely to deliver your license key.
Own It Outright
You pay once and it is yours to keep. No subscriptions, no renewal fees, no features locked behind a higher tier. Every Korerium app works the same way. Buy it, own it, and keep it as long as you use a Mac.
Simple on Purpose
Complexity is not a feature. Every product is stripped down to exactly what it needs to be. If it takes more than a few seconds to understand, we have not done our job.
No Compromise
Privacy is not a setting you toggle on. It is the foundation every product is built on from the first line of code. We do not cut corners, make exceptions, or bend on this. Ever.
