FAQ

Is this formal financial, tax, or technical advice?

No. It is a quick estimate and checking tool. Use qualified professionals, trading venues, official notices, or service terms for decisions.

Is data uploaded?

Only the required lookup fields are sent to the GoGo Tools backend, which queries public data sources. No account or password is needed.

How fresh are results?

API tools show source and fetch time. Some responses are cached briefly for speed and reliability.

Can I use other countries or currencies?

Yes, but keep money, rates, currency, and assumptions consistent within the same tool, and verify local rules.
