Why do I see values in multiple currencies instead of one?
FolioInsights keeps EUR positions in EUR, USD positions in USD, and so on. There is no live FX conversion. That is a deliberate choice: to convert to a single base currency we would have to call an exchange-rate API, which means your tickers and balances leaving your machine, plus an ongoing per-user cost that would push the price up or require a subscription.
In practice, per-currency totals are actually more accurate for reasoning about your portfolio. The EUR number is the one you can spend today; applying yesterday's USD→EUR rate to a US ETF does not turn it into euros you actually have. If a good offline option appears later (for example a manually pinned rate table) we will revisit this.
Why do I have to enter current prices by hand?
Same reason. A live price API would mean sending your ISINs to a third party on every load and paying for requests. Instead, the tool defaults to your last buy price from the CSV, which is always available offline. You can override it in the Prices tab whenever you want a fresher valuation.
If you only care about cost basis and realized P/L, manual prices do not matter — those numbers are already exact from your CSV. Current prices only affect the unrealized column and the net-worth chart's latest point.
Is this a replacement for a broker statement or tax advice?
No. FolioInsights is a personal analysis tool, not an official record. For taxes, rely on DeGiro's own reports or a qualified accountant. We just help you see what is in your account more clearly.
Can I use it on a phone?
Yes, the site works on mobile. The one step that is easier on a laptop is exporting the account.csv from DeGiro and uploading it, because DeGiro's web UI is built for desktop.
What happens to my data if I clear my browser?
It is gone. All transactions and manual prices live in your browser's IndexedDB, not on our
servers. The bright side: there is nothing to leak. The practical answer: keep your account.csv saved somewhere and reimport if you ever reset the browser.
