Made for people like you

If your life happens in more than one country, this is for you.

It doesn't matter where you are on the journey — moving, already settled abroad, or with your life split between two places. If your money lives in more than one currency, you know the mess. Here it ends.

From someone who lives between currencies

The app I needed didn't exist. So I built it.

More and more people have money that doesn't fit in one country: it arrives in different currencies and ends up scattered across accounts at home and abroad. I'm one of those people — and I'm also a developer. The question that kept going unanswered was the most basic one: adding it all up, how much do I really have? No spreadsheet or app answered it without treating one of my currencies as an exception. So I designed the tool that was missing: complete, truly multicurrency, and end-to-end encrypted by architectural decision, not by marketing. Not even I, on the server, can see your numbers. I built it to use — and I stand behind every decision in it.

The question was simple: adding it all up, how much do I have?

How it works

Three steps to see everything in one place.

No opening a bank account, no linking a card, no handing your data to anyone. You enter it, the app organizes it, and the full picture appears — in the currency you choose.

01

Add what's yours

Accounts, investments, debts and goals — each item in its own currency. You type it once.

02

The exchange rate does the rest

Currency conversion is automatic (live FX rates), with manual adjustment whenever you want. Real, euro, dollar — your call.

03

See the whole

Net worth, the month's budget, your future projection and your freedom number — all in a clean dashboard that fits your phone and your computer.

Real privacy

Not even we can see your numbers.

Most apps promise privacy and, deep down, read everything. Here it's different by design: your data is encrypted on your own device, with a key only you have, before it goes anywhere. What reaches our server is an unreadable blur. No tracking, no ads, no selling your behavior. Privacy isn't a feature — it's the foundation.

Under the hood: your password becomes a key via Argon2id; data is encrypted on your device with AES-256-GCM (browser WebCrypto) before any sync. The key never leaves your device.

End-to-end encryption (E2EE). If you lose your password and your recovery code, not even we can recover your data — that's exactly the point.

What the server stores
9f86d081…a8f3e71c…4c2b91d0…e7b0c442…2a9f6b13…8e4d7f0a…b91c3d52…6f1e0a8c…
Just this: an encrypted blob. No account name, no balance, no value — not even for us.

End-to-end encrypted

Your numbers are scrambled before they leave the device. The server only sees code.

The key is yours alone

Derived from your password, with a recovery code only you keep. No one else can open it.

No tracking, no ads

You're the user, not the product. We don't sell, don't spy, don't hand it over.

Your full picture

Simple on the surface. Complete underneath.

Behind the calm of the dashboard there's real depth. Every number answers a question that keeps you up at night — and answers it in the currency you understand.

Follow along together

The people who matter follow along — without ever moving your privacy out of place.

When financial life is shared, clarity has to be too. With Family Access, you share a read-only dashboard with someone you trust — partner, parent — through a link and a four-digit PIN. They follow the picture; no one changes a thing. And, true to our rule, it happens without breaking the encryption.

One link + one PIN
Read-only Sees the dashboard. Doesn't edit, delete or export.
E2EE intact: the server still can't see your values.

Brazilian income tax — BR only

When the taxman comes, your numbers are already in order.

The app pulls your net worth and builds your Assets & Rights document — with codes, descriptions and the two 12/31 columns — ready for your accountant to type in. <b>We don't file it, we don't send anything, we don't compute your tax.</b> We just take the chaos out of the way.Bens e Direitos — com código, descrição e as duas colunas de 31/12 — pronto pro seu contador digitar. Não declaramos, não enviamos nada, não calculamos imposto. Só tiramos o caos do caminho.

  • <b>Pulls from your net worth.</b> Every asset becomes a line with a suggested code and a ready description.Puxa do seu patrimônio. Cada bem vira uma linha com o código sugerido e a descrição pronta.
  • <b>The two 12/31 columns.</b> Prior year and base year, the way the tax office wants — and what you sold during the year lands correctly.As duas colunas de 31/12. Ano anterior e ano-base como a Receita pede — e o que você vendeu no ano entra certinho.
  • <b>Foreign assets, by the book.</b> Acquisition cost at the central-bank rate (PTAX) from the purchase date — the app doesn't make up values.Bens no exterior na régua. Custo de aquisição pela PTAX do BCB da data da compra — o app não inventa valor.
  • <b>Exports to PDF and spreadsheet</b> — and never leaves your device. Not even we can see your numbers.Sai em PDF e planilha — e nunca sai do seu aparelho. Nem nós vemos os seus números.

This is not your tax return. The app organizes — it doesn't file, doesn't send, doesn't give tax advice. Always check with an accountant.

Frequently asked questions

What people usually want to know.

Is it really free?+
The core is free forever: net worth, budget, investments, projection and independence. Pro (optional) unlocks Family Access, the IRPF organizer, the full PDF report and advanced projection — with a 14-day free trial. No card to get started.
Can I sign up now?+
Yes — sign-up is open and free. It's a new product, still being built: joining now means being among the first and helping shape what's coming.
Can you see my data?+
No. Everything is encrypted on your device before it leaves it. What we store is a blur not even we can read.
What if I lose my password?+
You get a recovery code when you sign up — keep it safe. Without the password and that code, not even we can open your data. It's the fair price of real privacy.
Which currencies does it work with?+
Each item keeps its own currency, and you choose which one to see the whole in. Real, euro, dollar and others — with automatic rates and manual adjustment.
If the app shuts down, do I lose my data?+
No. Your data is yours: export everything to JSON and CSV anytime, and the app keeps working offline on your device (local-first) even without our servers. No hostages.
Do I need to be online?+
No. The app is local-first: it works instantly and offline, and syncs encrypted when you're back online.
