Before you write
A lot of common questions are already answered on the FAQ page — things like how business days are counted, why a month-end date lands where it does, and whether your data is private (it is). If your question is there, you’ll get an answer instantly. If not, email away.
For questions about data and privacy specifically, see the Privacy Policy.
