These pages carry tax thresholds, dosage figures, electrical formulas and official lottery records, and rules change on their own schedule. If a figure on a page looks wrong, that report is the most useful message we can get. Please include:
We check the primary source before changing anything, and we will not swap a number because it “looks off”. If the source cannot be reached, the page says so instead of showing a guess.
We build calculators, not advice. We cannot review your individual tax return, interpret your lease, dose your pet, or tell you which numbers to play. Every tool here is an estimate for orientation, and the pages say so. For a decision that carries money, health or legal consequence, please take the figures to a qualified professional in your jurisdiction.
Email reaches us directly and is used only to answer you. We do not add senders to a mailing list, and nothing you type into the tools themselves ever leaves your browser — see our privacy policy for details.
