This Privacy Policy explains how Calculators.com.bd (“we”, “us”, “our”) collects, uses and protects information when you use our website and online calculators. By using the site you agree to this policy.
1. Calculations stay in your browser
Our calculators run entirely in your web browser using JavaScript. The values you type in — such as your age, height, weight, income, deposits or any other figures — are processed on your own device to produce a result. These inputs are not transmitted to or stored on our servers, and we do not keep a record of your individual calculations.
2. Information we do collect
- Usage & log data. Like most websites, our servers automatically record standard technical information such as your IP address, browser type, device, referring page and the pages you visit. This is used to operate, secure and improve the site.
- Information you choose to send us. If you contact us or submit a form (for example a message or enquiry), we receive the details you provide so we can respond.
- Cookies & analytics. We may use cookies and analytics tools (such as Google Analytics) to understand how the site is used. These may set their own cookies and collect aggregated, non-identifying usage statistics.
3. Advertising
We may display advertising, including from third-party ad networks. These networks may use cookies or similar technologies to show ads based on your visits to this and other websites. We do not share the figures you enter into calculators with advertisers.
4. How we use information
- To provide, maintain and improve the calculators and content.
- To analyse traffic and usage trends so we can make the site more useful.
- To keep the site secure and prevent abuse.
- To respond to messages or requests you send us.
5. Sharing of information
We do not sell your personal information. We may share limited data with service providers who help us run the site (for example hosting, analytics and advertising partners), or where required by law.
6. Health & financial data
Some calculators relate to health (BMI, calories, body fat, pregnancy and similar) or finance (tax, loans, savings and similar). Because these calculations happen in your browser and are not sent to us, we do not collect or store this sensitive information. Results are estimates only and are not medical, financial or legal advice — see our disclaimer at the bottom of every page.
7. Cookies & your choices
You can control or delete cookies through your browser settings, and you can opt out of personalised advertising via your ad or device settings. Disabling cookies will not stop the calculators from working, since they run locally.
8. Children’s privacy
This site is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.
9. Third-party links
Our pages may link to other websites. We are not responsible for the privacy practices or content of those sites; please review their own privacy policies.
10. Changes to this policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with a revised “Last updated” date.
