Questions, answered

Before you preheat.

What is free in WhiskMath?

All 13 web calculators, yield and manual-factor scaling, basic one-to-one pan-area conversion, the 30-item density catalog, copying, and up to three saved recipes. The free tier does not expire.

What is included with Lifetime Pro?

Multi-pan and depth-aware workflows, custom densities, unlimited recipe saves, scaled copies, formatted sharing, and versioned JSON transfer.

Does WhiskMath change package sizes?

No. In a line such as “1 14-oz can tomatoes,” WhiskMath scales the leading count and preserves “14-oz can” as descriptive text.

Does pan scaling tell me the baking time?

No. Pan geometry produces an ingredient scale factor. Oven behavior, batter depth, doneness, and baking time still require observation and recipe judgment.

What happens to recipes after a refund?

Nothing is deleted or hidden. Existing recipes remain readable, editable, and copyable; new Pro actions are locked until access returns.
