Yes. Every calculator is free, no signup is required and there is no usage limit.
Nowhere. The entire calculation runs inside your browser in JavaScript. The numbers you enter are never sent to a server and are not stored anywhere.
The formulas are standard, but the results are estimates. Real figures are affected by processing fees, surcharge, TDS and your lender's own rules. Always confirm the final number with your bank, chartered accountant or provider.
The financial year is shown at the top of the income tax calculator. After each Budget the slabs are updated in a single data file on the site.
