Honest financial
calculators.
brackt is a portfolio of free financial calculators, built because the existing tools — ClearTax, Groww, the bank-branded ones — all hide the math behind signup walls, ads, and product nudges. Here the math is open, the engine is verified against official sources, and nothing tracks what you type. India is the launch market.
