Privacy

What happens to the numbers I type?

They stay in this browser. This notice describes the calculator files. It is not legal advice, and it is not a certificate of compliance with any privacy law.

What does the calculator code do?

The four calculators read the numbers you type and compute a result in the browser. Their scripts do not call a server, do not use analytics or advertising code, and do not write the entries to browser storage. Refreshing the page, choosing Reset, or closing the tab clears what you typed. There is no account.

Each calculator form is set up so that, when JavaScript is on, Calculate stays on the page and does not submit the fields anywhere. This site has no server address for those fields. If JavaScript is off, the calculators do not run.

What if I open the files on my computer?

If you open the pages from a folder on your computer, the address usually starts with file://. That copy does not, by itself, send your measurements to a website. The canonical link in the page code points at a placeholder web address until the site is published. Your browser does not send the form numbers to that address.

What about a future web host?

If these files are later placed on a web host or a content network, that host may record connection details, such as an IP address and which page was requested. This site cannot say what a future host will log, how long it would keep those records, or where they would be stored. Adding hosting, analytics, ads, or a contact form would require this notice to be reviewed before those features are used.

What happens if I follow a link to another site?

Some calculator pages link to outside sources, such as a product data sheet or an industry note. This site does not send your calculator entries with those links. If you follow a link, your browser then contacts that other site, and that site has its own policy.

What does this notice leave undecided?

No owner street address, legal basis, retention schedule, or governing law is stated here, because none is configured. Calculator entries stay in the browser unless you choose to put them in an email. The Contact page lists r.rauf.rai@gmail.com for Abdul Rauf. A message you send goes through your email provider and Gmail, not through a form on this site. This notice does not say how long that mailbox keeps a message, and it does not promise deletion.
