Your entire financial picture, the tax math and the forecast.

Stocks, property, cash, crypto and what you owe, synced read-only from your brokers, banks and exchanges into a private database of your own.

The Krosos dashboard: net-worth chart, asset and risk allocation for a €585,000 portfolio

Everything in

Everything you own,
minus what you owe.

Every asset class, plus the mortgage and loans against them. The total is your real net worth, not your broker's slice of it.

Stocks & ETFs

Brokers sync read-only; prices update themselves.

Cash & savings

Bank accounts via EU open banking, in any currency.

Money-market funds

XEON, Spiko and friends, with yield tracked as interest.

Property

Revalues itself yearly; the mortgage amortizes monthly.

Crypto

Exchanges, wallets and staking, including cold storage.

Pension

Workplace and private pots count too.

Commodities & valuables

Gold, the car, the watch. Value schedules depreciate them honestly.

What you owe

Mortgages, loans and provisions, subtracted where they belong.

Automatic sync

Synced while you sleep.

If it holds value, it syncs: brokers, banks, funds, exchanges and wallets, all read-only. Anything without an API comes in by CSV. No more spreadsheet Sundays.

Connected sources in Krosos: bank via open banking, Binance, Kraken, Trading 212 and on-chain wallets, all read-only

Import review

You approve every transaction.

Imports land in a review queue first: keep, dismiss, merge, or reclassify. Nothing enters your ledger without you.

  • Trades, rewards, deposits and transfers, classified for you
  • The kind you confirm is exactly what the tax engine reads
  • Re-syncing never duplicates a thing
The review queue: pending Kraken rewards, a trade and a deposit waiting for approval

Tax engine

Know your gain before the tax office asks.

Every sale is matched to the lots you bought: FIFO or weighted average, your country's rates and exemptions applied.

  • Capital gains, dividends and interest, each at its own rate
  • Presets for Belgium (2026 rules included), France and Germany
  • Every figure explains itself, down to the lot
The Krosos Tax tab: capital gains under the Belgian exemption, disposals matched to their lots

History & forecast

Watch it grow. See where it's heading.

Every day's net worth is kept, whether or not you open the app. The forecast engine projects decades ahead (income, spending, pensions, taxes, market swings) down to the month you could stop working.

The Forecast tab: a net-worth projection by asset class, with gain sources broken down

Private by architecture

Your numbers are
nobody's business.

Your own database, or your own computer

Hosted, your data lives in its own private database, never a shared table. Or run the desktop app and keep everything on your own machine, no server of ours at all.

Nobody can move your money

Every connection uses read-only keys, encrypted at rest. Krosos sees balances; it can never trade or withdraw a cent.

Leave whenever you like

Full export of your database, one-click deletion, no trackers. Leaving is easy. That's the point.

Beyond the dashboard

It comes to you.

Telegram bot

Your own private bot: ask for your net worth, log a trade in plain language.

Updates & alerts

A weekly or monthly digest of how your net worth moved, milestones celebrated, AI news on your largest holdings, and a nudge when your mix drifts. Email or Telegram, all opt-in.

API & agent access

Ask Claude or ChatGPT about your money: mint a read-only token, hand your assistant the ready-made skill, and it answers from your real numbers. An OpenAPI spec covers your own scripts too. How it works →

Joint accounts

Invite your partner or family, each with their own Google sign-in. One shared ledger, one household net worth.

FAQ

Questions, answered

Something else on your mind? Write to [email protected].

What can I track with Krosos?

Pretty much anything you own, like stocks, ETFs, cash, savings, bonds, money-market funds, real estate, crypto and private holdings, plus what you owe, like mortgages and loans, so the total is your true net worth. Synced automatically where there's an API, entered manually or via CSV where there isn't.

Which accounts sync automatically?

Stock brokers (Trading 212 and Interactive Brokers) sync your positions, ETFs and cash read-only. Bank accounts connect through open banking across the EU, and Spiko money-market funds sync too. On the crypto side, seven exchanges (Binance, Bybit, Coinbase, Kraken, Bitstamp, Bitvavo and Bitpanda) connect via read-only API keys, plus on-chain wallets by address (including Solana and Bitcoin). Stock, ETF, crypto and FX prices update automatically; everything else can be entered manually or imported from CSV. Full list →

Does it do my taxes?

It does the arithmetic. The tax engine replays your ledger, matches every sale to the lots you bought (FIFO or weighted average), applies your country's rates and exemptions (presets for Belgium's new 10% capital gains tax, with its €10,000 annual exemption and 2026 basis reset, plus France and Germany), and shows the estimated tax per year, with every figure traceable to its lots. It's an estimate to bring to your accountant or declaration, not tax advice. How it works →

Do I have to connect my accounts?

No. Connections are optional, and plenty of people track everything with manual entries and CSV imports. You decide what gets linked.

Can I import from a broker statement or another tool?

Yes. CSV import covers holdings and net-worth history, and there's a copy-paste prompt that turns any broker statement or spreadsheet into the right format using ChatGPT or Claude. Connection imports (Kraken, Spiko, on-chain wallets) land in a review queue where you approve every row before it touches your ledger.

Will Krosos keep me in the loop?

Optionally, yes. A weekly or monthly email digest shows how your net worth moved, a weekly AI-written news digest surfaces what actually happened to your largest holdings, and allocation-drift alerts let you set a target asset mix and get nudged when you wander from it. All opt-in, so there's no noise unless you want it.

What makes Krosos different from other trackers?

Three things: completeness, privacy, and the tax math. It's built to hold your entire financial picture, not just one broker. Every customer gets a private database of their own (on our servers or on their own computer) instead of a row in a shared one. And the tax engine matches every sale to the lots you bought and estimates capital gains tax per country, with presets for Belgium (including the 2026 basis reset), France and Germany.

Can you see my actual numbers?

Everything lives in a private database of your own, with credentials encrypted at rest and backups encrypted with a key unique to your account. To compute balances while you're signed in, the server does read your data, so this is honestly not end-to-end encryption. No hosted finance app's is. And if you'd rather not take anyone's word for it: the desktop app keeps everything on your own computer, where the answer is simply no. More on security →

Are my exchange API keys safe?

Keys are stored encrypted at rest with a key unique to your account, are never shown again after you save them, and never appear in logs or API responses. We require read-only keys: Krosos can see your balances, but can never trade, withdraw or move a cent of your money. Hosted plans run in EU data centres with nightly encrypted backups. More on security →

Can I take my data and leave?

Yes, at any time. One-click export of your complete database (plus JSON), and a delete-everything button. After cancellation, your data is retained for 30 days, then permanently deleted.

Is this financial advice?

No. Krosos is a tracking and reporting tool. It doesn't recommend investments, execute trades, or hold your assets, and its tax figures are estimates, not advice. See our terms of service.
