Questions
- Does it cost anything?
- No. The calculators are free to use and to embed, with no limit.
- Does the widget collect data from my visitors?
- No. The maths runs in the visitor's browser; nothing they type is sent anywhere.
- Can I change the size?
- Yes: change the width and height in the code. The last line (the script) sets the height to fit on phones too; if your site doesn't allow scripts, leave it out and the calculator scrolls inside its frame. It follows the visitor's light or dark setting.
