Is my data saved or sent anywhere?
No. The calculation runs in your browser and nothing is uploaded.
Are the results exact?
The maths is exact for the values you enter, but real life can differ. Use the result as a guide.
Is my file uploaded to a server?
No. Everything happens inside your browser on your own device. Your files are never sent to us or anyone else.
Is it free?
