Your privacy is a fundamental right. Learn exactly how Calculator Expert handles your data — openly, honestly, and with nothing to hide.
Welcome to Calculator Expert ("we," "us," "our"), accessible at www.calculatorexpert.online. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website and use our free online calculator tools.
At Calculator Expert, privacy is not an afterthought — it is a core design principle. We have built our entire platform from the ground up with the goal of giving every user access to professional-grade calculation tools without ever requiring them to surrender their personal data. Whether you are calculating your loan EMI, checking your BMI, or solving a quadratic equation, none of that information ever leaves your device.
Please read this Privacy Policy carefully. By accessing or using Calculator Expert, you agree to the terms described in this document. If you disagree with any part of this policy, please discontinue use of the website. If you have questions at any time, you can reach our team at support@calculatorexpert.online.
Short version: We collect minimal, anonymised technical data to keep our website running and improving. We do not collect the values you enter into any calculator. We use Google AdSense to display ads. We never sell your data.
This policy applies to all visitors, users, and others who access the website. It covers data collected through the website directly, through cookies and similar tracking technologies, and through third-party services such as Google Analytics and Google AdSense.
Calculator Expert collects the minimum amount of information necessary to operate, maintain, and improve our website. We categorise the information we collect into two types: information collected automatically and information you voluntarily provide.
When you visit Calculator Expert, our servers and analytics tools may automatically record certain technical information. This information is anonymised and aggregated — it cannot be used to identify you personally.
We only collect personally identifiable information that you choose to provide — for example, when you contact us through our Contact page. This may include your name, email address, and the contents of your message.
✅ Important: We do not ask for, collect, or store any information entered into our calculators — including financial figures, health data, personal measurements, or any other calculation inputs. See Section 3 for full details.
This section is arguably the most important in our entire Privacy Policy, and we want to be absolutely clear: Calculator Expert does not collect, transmit, log, or store any data you enter into any of our calculators.
Every calculator on our platform — from our EMI Calculator to our BMI Calculator, from the Compound Interest Calculator to the Quadratic Equation Solver — processes all inputs and produces all outputs entirely within your own browser using JavaScript. No calculation data is ever sent to our servers. This is not merely a policy choice; it is an architectural guarantee built into the design of our platform.
🔐 Privacy by Architecture: The privacy of your calculation data is guaranteed by the technical design of our platform — not just by policy. Even if we wanted to see your input data, our system is not built to capture it.
Calculator Expert uses cookies and similar tracking technologies to provide functionality, analyse usage, and support our advertising. Cookies are small text files stored on your device by your browser. They help us understand how our website is used and allow us to show relevant advertisements.
You can control and manage cookies through your browser settings. Most browsers allow you to refuse or delete cookies. Please note that disabling certain cookies may affect the functionality of our website or the relevance of advertisements you see.
To manage your Google ad personalisation settings, visit adssettings.google.com. To opt out of Google Analytics, you can install the Google Analytics Opt-out Browser Add-on.
⚠️ Note: Disabling advertising cookies will not remove advertisements from our site — it will only make them less personalised. We use advertising to keep Calculator Expert free for everyone.
Calculator Expert is a free platform. To sustain our operations — including server costs, development, and ongoing maintenance — we display advertisements on our website through Google AdSense, an advertising service provided by Google LLC.
Google AdSense uses cookies and web beacons to serve ads based on a user's prior visits to our website and other websites on the internet. This allows Google to display advertisements that are more relevant to your interests. You can learn more about how Google uses your data at policies.google.com/technologies/ads.
While we rely on advertising revenue to stay free, we maintain strict standards around the advertising shown on Calculator Expert. We do not accept advertisements that are misleading, deceptive, or irrelevant to our users. We do not allow advertisements that promote harmful products or services. Our goal is for advertising to be a helpful complement to our content — not a distraction from it.
✅ Our Commitment: We will never display advertisements in a way that compromises your user experience or obscures important calculator functionality. Ads are placed in clearly designated areas that do not interfere with calculations.
To operate Calculator Expert effectively, we use a small number of carefully selected third-party services. Each of these services has its own privacy policy, and we encourage you to review them:
We do not sell, trade, or otherwise transfer your personally identifiable information to third parties other than those described above, and only to the extent required for our website to function. We do not share your data with data brokers, advertising networks beyond Google AdSense, or any unrelated third parties.
Our website may contain links to external websites. Please be aware that we have no control over the content or privacy practices of external sites and we accept no responsibility for those third-party sites. We encourage you to read the privacy policy of every website you visit.
Calculator Expert is designed to be a useful educational and practical resource for people of all ages, including students. Our tools are widely used by school and college students for mathematics, science, and financial literacy purposes.
However, our platform does not knowingly collect any personally identifiable information from children under the age of 13. We do not require registration, and our calculators do not ask users to input any information that could identify them personally.
If you are a parent or guardian and you believe that your child has provided us with personal information through our contact form or any other means, please contact us immediately at support@calculatorexpert.online. We will take prompt steps to delete such information from our records.
⚠️ Parents & Guardians: While our calculators are safe and educational, please be aware that Google AdSense may display ads on our site. If you prefer an ad-free browsing experience for children, we recommend using ad-blocking browser extensions or enabling family-safe browsing modes.
We are committed to complying with the Children's Online Privacy Protection Act (COPPA) in the United States and applicable children's data protection laws in other jurisdictions, including GDPR protections for minors in the European Union.
Depending on your location, you may have certain rights regarding your personal data under applicable privacy laws including the General Data Protection Regulation (GDPR) for users in the European Economic Area, the California Consumer Privacy Act (CCPA) for users in California, and the Personal Data Protection Bill (PDPB) for users in India.
You have the right to know what personal data we hold about you and how it is used.
You can request correction of any inaccurate personal information we hold about you.
You can request deletion of personal data we hold, subject to certain legal exceptions.
You can request a copy of personal data we hold in a portable, machine-readable format.
You can object to the processing of your personal data for certain purposes including direct marketing.
Where processing is based on consent, you may withdraw it at any time without affecting prior processing.
Since Calculator Expert does not collect your calculation data, the most common forms of personal data we may hold are: contact form submissions (name + email) and anonymised analytics data. To exercise any of your rights, contact us at support@calculatorexpert.online. We will respond within 30 days.
If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA), including the right to know about personal information collected, the right to delete personal information, and the right to opt out of the sale of personal information. Calculator Expert does not sell personal information. To submit a CCPA request, contact us at support@calculatorexpert.online.
The security of your information is a priority for us. We implement a variety of technical and administrative security measures to protect our website and any personal data we process.
While we implement best practices, please understand that no method of transmission over the internet or method of electronic storage is 100% secure. We cannot guarantee absolute security, but we are committed to protecting your information to the highest commercially reasonable standard.
✅ The most important security feature of Calculator Expert: Because your calculation data never leaves your browser, it is impossible for our servers to be breached in a way that exposes your financial, health, or personal calculation inputs. Privacy by design is the strongest security measure we offer.
We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors. When we make material changes, we will update the "Last Updated" date at the top of this page.
We encourage you to review this Privacy Policy periodically to stay informed about how we are protecting your information. Your continued use of Calculator Expert after any changes to this Privacy Policy constitutes your acceptance of the updated policy.
If we make changes that significantly affect your rights or how we process your personal data, we will make reasonable efforts to notify you through prominent notice on our website or through other appropriate means.
If you have any questions, concerns, or requests regarding this Privacy Policy or our data practices, please do not hesitate to reach out. Our team takes privacy inquiries seriously and will respond within 30 days of receiving your message.
For urgent data deletion or breach notifications, we aim to respond within 72 hours.
