Quick summary
Calculator inputs are processed in your browser and are not sent to a server for calculation.
The contact form collects your name, email address, subject, message, and submission timestamp so the site owner can respond.
This build does not include analytics, tracking pixels, or third-party calculator scripts.
The calculators on this site run in your browser. Numbers entered into forms are used by JavaScript on the page to calculate results. The site does not send calculator inputs to a server for processing.
If you change light or dark mode, the site stores a small preference in your browser’s local storage so the same theme can be restored on your next visit.
The contact form collects your name, email address, subject, message, and submission timestamp so the site owner can respond to support requests, calculator corrections, accessibility issues, and content suggestions.
Contact form messages are delivered to contactkt7@gmail.com using a server-side email route with Nodemailer. Do not send passwords, private financial records, medical details, or other sensitive information through the form.
What is included in each submission
This build does not include analytics, tracking pixels, or third-party calculator scripts. If the site owner adds hosting, analytics, advertising, or other services later, those services should be disclosed in this policy.
The site is intended for general educational and planning use. Children should not submit personal, medical, financial, or location details through calculator forms.
