Privacy Policy

Last Updated: October 2023

1. Introduction

Welcome to IntegralsOnline ("we","our", or"us"). We are committed to protecting your personal information and your right to privacy. If you have any questions or concerns about this privacy notice, or our practices with regards to your personal information, please contact us at contact@integralsonline.com.

When you visit our website https://integralsonline.com (the"Website"), and more generally, use any of our services (the"Services", which include the Website and our mathematical calculation engines), we appreciate that you are trusting us with your information. We take your privacy very seriously. In this privacy notice, we seek to explain to you in the clearest way possible what information we collect, how we use it, and what rights you have in relation to it.

Please read this privacy notice carefully as it will help you understand what we do with the information that we collect. This Privacy Policy applies to all information collected through our Services, as well as any related services, sales, marketing, or events.

2. Mathematical Data Processing

IntegralsOnline is fundamentally a computational tool designed for educational purposes. We understand that users may have concerns about the privacy of the equations, matrices, or mathematical functions they input into our solvers.

Ephemeral Processing: The mathematical expressions, equations, limits, derivatives, and integral bounds you enter into our calculators are processed strictly for the purpose of generating your requested mathematical result and step-by-step solution. We do not store, save, log, or index your mathematical inputs in any permanent database.

No Personal Linkage: Because our website does not require user accounts, logins, or authentication, any mathematical queries executed by the engine are entirely anonymous and cannot be tied back to your personal identity, name, or email address. Your homework assignments and engineering calculations remain private.

3. Log Data and Server Analytics

Like almost all modern web applications, our servers automatically collect certain information when you visit, use, or navigate the Website. This information does not reveal your specific identity (like your name or contact information) but may include device and usage information.

The data we automatically collect includes:

• Log and Usage Data: Service-related, diagnostic, usage, and performance information our servers automatically collect when you access or use our Website and which we record in log files. This includes your IP address, browser type, and settings.
• Device Data: Information about your computer, phone, tablet, or other device you use to access the Website. Depending on the device used, this device data may include information such as your IP address (or proxy server), device and application identification numbers, location, browser type, hardware model, Internet service provider, and mobile carrier.

Purpose of Collection: We use this technical data strictly for maintaining the security and operation of our Website, preventing DDoS attacks against our computational engines, and for our internal analytics and reporting purposes to understand global traffic patterns.

4. Cookies and Tracking Technologies

We may use cookies and similar tracking technologies (like web beacons and pixels) to access or store information.

Functional Cookies: We use essential cookies to remember your preferences across sessions. For example, if you toggle the website into"Dark Mode" using the theme switcher, we store a small token in your local storage so that your preference is remembered the next time you visit. We also use functional cookies to remember if you prefer"Definite" or"Indefinite" modes on the integral calculator.

Analytics Cookies: We utilize third-party analytics services (such as Google Analytics) to understand how users engage with our site. These tools collect aggregated, anonymized data such as page views, time spent on calculators, and bounce rates. This helps us determine which new calculators to build next.

You have the right to accept or reject cookies. You can exercise your cookie rights by setting your preferences in your web browser controls. If you choose to reject cookies, you may still use our website, though some functionality (like saving your Dark Mode preference) may be restricted.

5. Sharing of Information

We do not share, sell, rent, or trade any of your information with third parties for their promotional purposes. We only share and disclose your information in the following situations:

• Compliance with Laws: We may disclose your information where we are legally required to do so in order to comply with applicable law, governmental requests, a judicial proceeding, court order, or legal process.
• Vital Interests and Legal Rights: We may disclose your information where we believe it is necessary to investigate, prevent, or take action regarding potential violations of our policies, suspected fraud, situations involving potential threats to the safety of any person and illegal activities, or as evidence in litigation in which we are involved.
• Service Providers: We may share your data with third-party vendors, service providers, contractors, or agents who perform services for us or on our behalf and require access to such information to do that work (e.g., hosting providers like Vercel).

6. Information Retention

We will only keep your personal information for as long as it is necessary for the purposes set out in this privacy notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). Because we do not use accounts, the only personal information we might retain is correspondence sent to our contact email address, which is kept only as long as necessary to resolve your inquiry.

7. Children's Privacy

While our mathematical tools are inherently educational and often used by students, we do not knowingly solicit data from or market to children under 13 years of age. By using the Website, you represent that you are at least 13 or that you are the parent or guardian of such a minor and consent to such minor dependent’s use of the Website.

8. Updates to this Policy

We may update this privacy notice from time to time. The updated version will be indicated by an updated"Revised" date and the updated version will be effective as soon as it is accessible. If we make material changes to this privacy notice, we may notify you either by prominently posting a notice of such changes or by directly sending you a notification.
