Does Calculator Studio upload my numbers to any server?
No. Every calculator runs in your browser, and nothing you enter is sent to a server. The Currency Converter downloads the latest exchange-rate table, but your amounts stay on your device.
Are the currency conversion rates live?
Close to it. The Currency Converter loads recent market rates from a public exchange-rate feed (cached for up to an hour) and shows when they were last updated. If the feed can't be reached, it uses a built-in reference table and tells you. For real transactions, check your bank's rate.
Is the Salary Calculator a substitute for tax advice?
No. It estimates take-home pay after Provident Fund, professional tax, and any other deductions you enter, but it doesn't calculate income tax.
