Frequently asked questions
- Are calculator numbers uploaded?
- No. Percentage, EMI, GST, and BMI math run in your browser. A draft can stay on this device so refresh does not wipe the job; nothing is uploaded.
- Are these official quotes or a diagnosis?
- No. EMI is an estimate, not a bank sanction letter. GST splits a price, it is not a GST return. BMI and calorie figures are not a medical diagnosis. Percentage, discount, and tip are everyday arithmetic on the same category page list.
