What you type

The calculators work out your results in your browser. We do not ask for your name or phone number, there are no accounts, and we do not store the figures you enter.

The figures you enter are kept in the page address so you can bookmark or share a result. Like any web address, it reaches our host, Cloudflare, and Google’s ad service when a page is opened with figures in its address, for example from a bookmark, a shared link or a reload. If you would rather keep your figures to yourself, do not bookmark or share those links.

Advertising

We show ads through Google AdSense. Google and its partners use cookies to show ads based on your visits to this and other websites. You can turn off personalised ads in Google’s Ad Settings, and read how Google uses data from sites that use its services.

Visitors from the European Economic Area, the UK and Switzerland are asked for consent before personalised ads are shown.

Visitor statistics

We use Cloudflare Web Analytics to count page views. It does not use cookies and does not track you across sites.

Your rights

Under India’s Digital Personal Data Protection Act, 2023 you may ask what personal data we hold about you and ask us to correct or erase it. Since we collect none beyond what you send by email, write to jay.swd@gmail.com with any request.
