Why stackers need something better

The tools we had
were never built for us.

No real-time picture

Spreadsheets show you what you paid — not what your stack is worth right now. With no live spot prices, no gain/loss calculation and no portfolio chart, you're always flying blind on the actual value of what you own.

Apps sell your data

Most portfolio apps survive by selling your financial habits to advertisers and data brokers. Your stack is private intelligence — the amounts you hold, what you paid, when you bought. It shouldn't leave your hands.

Nothing was built for us

I searched everywhere. I could not find a single tracker that was trustworthy, secure, affordable, and actually easy to use — all at once. So I built one myself.

The solution

A vault worthy
of what's inside it.

A private ledger for your gold and silver — gorgeous, fast, built around one principle: your data belongs to you.

Track every piece. Coin or bar, gold or silver — name, mint, weight, purity from .999 to a custom %, what you paid, spot at purchase. All of it.
Live prices, twice daily. Spot prices refreshed automatically — no API keys to manage, no manual updates.
Portfolio charts and milestones. Watch your value grow in real time. Hit a milestone — the vault celebrates.
Encrypted on your device. Full stop. Everything is encrypted locally before anything else happens. Nothing leaves in readable form — your stack stays where it belongs.

Privacy by design

Encrypted before it ever leaves your device.

AES-256-GCM encryption, on your device
Your vault is encrypted directly on your device before anything else happens. The key never leaves your hands — there is no server to breach because nothing readable ever leaves your device.
Your device. Your data. No exceptions.
Everything is stored locally on your own phone or computer, encrypted at rest. No third-party cloud. No hidden sync. No data leaving your device without your knowledge. Your vault lives where you live.
No analytics. No tracking. No ads.
There is no Google Analytics, no Facebook Pixel, no data brokers. Your financial data is not a product here.
PIN + passphrase, two layers
A 6-digit PIN for quick daily access. A recovery passphrase as the real encryption key — the only thing that can unlock a new device.

Everything in the vault

Built around how
stackers actually think.

Milestones & celebrations

Cross 1 oz, 5 oz, 100 oz — the vault notices and celebrates. Ten gold milestones, ten silver milestones. Progress rings show exactly how close you are.

Collections & showcase

Group your pieces into named displays — Queen's Beasts, your Lunar sets, your finest bars. Gallery view with covers generated from your own photos.

My story

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 — one that 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 privacy-first platform designed specifically for gold and silver stackers. A place to track holdings, monitor value, organise collections — and do it all without ads, trackers, third parties, or unnecessary data collection.

Vault Hollandia is built around one simple principle: your stack lives on your device, encrypted, where only you can read it.

I'm not a large corporation or a tech company. I'm simply a fellow stacker who wanted a better way to keep track of what I've worked hard to acquire.

A passion project by a stacker, for a stacker.

For the serious stacker

Your stack deserves this

Your metals are real.
Your tracker should be too.

Stop trusting your financial data to apps that see it as inventory. Take back your privacy, track your stack properly, and never look at a spreadsheet again.
