A fellow stacker,
not a company.

A passion project by a stacker, for a stacker.

The Vault Hollandia wax seal: a crowned lion pressed in red wax

Hello,

As my own stack grew and I wanted a simple overview to keep track of it, I noticed there wasn’t really a platform that offered that, that also seemed trustworthy or was affordable.

I thought of using Excel, but I missed the key feature of seeing what my stack would be worth in the moment, based on up-to-date spot prices.

That’s why I built Vault Hollandia. What started as a personal passion project evolved into a full platform designed specifically for gold and silver stackers. A place to track holdings, monitor value and organise collections  all without trackers, third parties, or unnecessary data collection. Everything stored locally on your own devices.

I’m not a large corporation or a tech company. I’m simply a fellow Christian stacker who wanted a better way to keep track of my stack, and decided to share it with the stacker community in the hopes others will enjoy it as much as I do.

It is my personal goal to become the number 1 app in the gold & silver communities that people trust and use to keep track of their stack or collections.

My plans for the future of Vault Hollandia.

Where this is going. Two tracks: what your support makes possible, and the features I want to build.

Support roadmap

Funded by your support

Every donation goes back into Vault Hollandia. As support grows, it helps fund independent security testing, platform expansion and the costs required to keep the project available.

iOS / App Store

Vault Hollandia on iPhone and iPad. Live on the App Store since September 2026.

Windows code signing

Sign the direct Windows download so it no longer shows the "unknown publisher" warning during install.

Independent security audit

Pay an outside security team to review the app and confirm your vault is as safe as it should be.

Feature roadmap

What I want to build

Ideas and features planned for Vault Hollandia, to make tracking your stack even better.

More precious metals

Expand Vault Hollandia beyond gold and silver with support for platinum, palladium and maybe copper.

Goldback support

Add proper support for Goldbacks, including denomination, gold content and live value calculations.

Photo to stack recognition

Take a photo of a coin or bar and let Vault Hollandia identify the item and automatically fill in details such as metal, weight, purity, mint, series and year.

Wishlist

Keep a separate list of coins, bars or collectibles you are looking to add to your stack.

Bitcoin under consideration

Potentially allow users to include Bitcoin alongside precious metals, while keeping Vault Hollandia primarily focused on physical assets.

Share card

When you want to share a special piece, and its details you can do so easily from within the app

“Gold is the money of kings, silver is the money of gentlemen.”
A Quote that stuck with me after seeing it on Reddit

A small note: every backdrop photograph in the vault, and on this site, was taken by me, the founder, of pieces from my own collection.
