Before you write

AdAccount/help questions — we can't reset your account because we don't have one. All tools work without login.
Lost data — because inputs are never sent to our servers, we cannot recover a past calculation.
Tax/financial advice — we cannot provide personal advice. See our Terms and consult a qualified professional.
