// How it runs

Four ways to run it — every one built to respect you.

01

Cloud
AI

AI powered by your own provider key. Your data goes where you send it — never through us. Runs on your Mac; a one-time purchase.

02

Self-
Hosted

Software you run on your own server — NAS, VPS or Docker. A one-time purchase; your data never leaves your infrastructure.

03

Hosted
By Us

Services we host so you don't have to. A private, isolated instance — encrypted, never sold or used to train AI. A subscription you can cancel anytime.

04

On Your
Mac

Apps that run entirely on your Mac. Your files never leave your machine — no cloud, no server. Buy once, yours forever.

About.Sys

Perfect Paradox is an independent software company building focused Mac tools for people who want their computer to work for them — not the other way around.

The paradox in our name is simple: software can be powerful and respectful. It can be a real business and never sell you out. We build as if every app were running on our own machine — because it is.
