Family system

Data minimisation throughout: age bands not birthdates, no names required, delete any time.

This section answers what a household decision is worth. Add a partner, children and childcare and PayLens combines both incomes with the subsidy and the tax on the extra day, so you can see whether another workday, a change in care or a change in hours leaves the household ahead.
