The private metals tracker
PIN-locked. End-to-end encrypted. Everything lives on your device and nowhere else. Gold, silver, collections, history — fully private, always.
Choose your platform
Vault Hollandia Noir is being built as a native app for every major platform. Choose yours below.
The Android app is actively in development. A fully native, private vault — no web browser required. Pure local storage. No account, no cloud.
A dedicated Windows desktop app. Track your entire stack from your PC, fully offline and encrypted. No browser, no internet connection required.
Apple requires a developer account to publish on iOS. That costs €100 a year — and I don't want to spend it before I know people will actually use the app.
If you want a native iOS app, leave a small donation. Once I get close to that threshold, I'll build it. Simple as that.
The Apple developer account that unlocks iOS also covers macOS — it's the same €100/year. So iOS and macOS essentially come together.
If you donate toward the iOS target, you're also helping the Mac app happen. One donation, two platforms. Fair deal.
Why it's different
Your stack stays where it belongs — on your phone or computer, encrypted, never uploaded, never shared. Not even with me.
AES-256-GCM, PIN-locked, with a recovery passphrase as the true key. Not "secured" — actually encrypted before anything gets stored.
Live spot prices. Portfolio charts. Milestone celebrations. The troy ounce math done right. Everything a serious stacker needs — nothing they don't.
