What it is not

Gratuity Calculator: Simple & Fast is a calculation utility. It is not a banking product, a payments service, or a financial-advisory product. It does not move money and it does not store your bills.

How the maths is handled

Every amount is produced by a deterministic, integer-based money engine — never by a language model. A separate verification layer independently re-computes the same figures through a different code path. If the two ever disagree, the deterministic engine remains authoritative and the result is recalculated and re-validated rather than guessed.
