Questions, feedback, or found something that looks wrong? We'd like to hear about it.
Before you write
Since every calculation runs locally in your browser, we can't see your data and can't debug an issue by looking up your session. If you're reporting a calculation or parsing problem, it helps a lot to include:
- The exact input you pasted or typed
- Whether you had sample or population mode selected
- What you expected versus what the calculator showed
- Your browser and device (e.g. Chrome on Windows, Safari on iPhone)
For anything else — feature requests, general feedback, or partnership questions — just email us directly.
