Frequently Asked Questions
Quick answers about our calculators and how we run the site.
Are the calculators free?
Yes. All calculators on this site are free to use. You don’t need to create an account or sign up. Just open a calculator and start using it.
Do you store my calculator inputs?
No. The calculators run in your browser. We don’t save the numbers you enter. Your inputs never leave your device for calculation purposes.
How is my data used?
We don’t sell your personal data. We may use cookies for analytics and for advertising (e.g. Google AdSense). If you contact us, we use your message and contact details only to respond. For full details, see our Privacy Policy.
Can I use the results for real financial decisions?
Our tools are for education and estimation only. They are not financial, tax, or legal advice. Results are estimates. For decisions about your money, taxes, or legal matters, please consult a qualified professional.
How do I use the contact form?
Go to the Contact page, fill in your name, email, subject, and message, then click “Send message.” We’ll receive your message by email and respond as soon as we can. We don’t use your contact details for marketing unless you ask us to.
Why do I see ads on the site?
We use advertising (e.g. Google AdSense) to help cover the cost of running the site so we can keep the calculators free. You can control ad personalization in your Google Ads settings if you prefer.
I found an error in a calculator. What should I do?
Please tell us via the Contact page. Include which calculator and what seems wrong (e.g. formula or example). We’ll review and fix it when possible.
