About
Hi, I'm Craig.
Creator, Darkfolio
The Moment
I'm a philosophy professor. I write about financial privacy. And one evening a few years ago, I was checking my portfolio in a popular tracking app when a thought stopped me cold: this app knows exactly what I own.
Not just the app. The company behind it. Their analytics partners. Anyone who breached their servers. Anyone who subpoenaed their records. I'd handed over a detailed map of my financial life — which assets, how much, how often I checked — in exchange for a line chart and a percentage.
I started looking at what could go wrong, and the list was longer than I expected. Data brokers sell financial profiles that end up in the wrong hands. Portfolio trackers have exposed the personal information of millions of people in the last few years. So-called wrench attacks — where someone forces you to hand over crypto — have been rising steadily. The common thread: someone knew too much — what the victim held, or simply who they were and that they held anything.
The Question
Most privacy-focused apps start with a promise: we won't look at your data. But promises can be broken — by bad actors, by policy changes, by court orders, by breaches.
What if you didn't need the promise?
That question became Darkfolio. Every user receives the same complete set of prices — all 7,000+ assets, every time. Your device extracts what it needs locally. The server can't reveal your holdings because it never learns them. With Tor enabled, it doesn't know who's asking, either. Everything is encrypted on your device and stays there. You don't have to take our word for it — the app includes tools to verify blind pricing yourself.
The Trade-offs
I want to be honest about what this approach costs. There's no cloud sync — because syncing would mean storing your data on a server. That also means no multi-device access. There's no "forgot PIN" recovery — because if we could recover it, so could someone else. If you lose your phone, your data is gone. These are real limitations, and they're deliberate.
Ghost Mode uses PINs, not Face ID — because Face ID can't distinguish between two vaults. Fetching prices for 7,000+ assets in bulk instead of just yours adds a small amount of latency. No architecture is perfect, and we won't pretend ours is.
Every one of these is a choice. We chose privacy over convenience — and then worked to close the gap as much as we could.
Why It Matters
I built Darkfolio because I wanted to use it — it's the app I always wished I had. I use it every day.
If you care about the same things, I think you'll like what we've made.
