How to send a useful bug report
Include the calculator name or URL, the values you entered, the result you received and what you expected. A screenshot can also be useful for visual or mobile issues.
Please do not send sensitive data
Do not send passwords, banking credentials, national identification numbers, health records or other unnecessary sensitive information. Calculator inputs are intended to be processed in the browser, and most support questions can be diagnosed with non-sensitive example values.
