This Privacy Policy explains how Integralcalculator.info handles information when you visit the website, use calculators, create an account, purchase Premium, reset a password, or send a message through the contact form.
Information We May Process
We may process information such as IP address, browser user agent, language header, page path, timestamps, calculator slug, math input, selected variable, bounds, request status, account name, email address, password hash, activation status, Premium solve balance, Premium order reference, contact form details, and email delivery information.
Account Information
If you register, we store your name, email address, password hash, activation status, email verification time, and related account timestamps. Passwords are stored as hashes, not as readable plain text.
Email Confirmation and Password Reset
The site uses email templates stored in the database to send account activation, password reset, and Premium order messages. Password reset and activation links use temporary tokens that are stored as hashes and expire after a limited time.
Premium Information
If you use Premium, we may store Premium order references, order status, solve quantity, amount, currency, paid time, Premium solve balance, and Premium expiration date. Payment card or wallet details should be handled by the connected payment provider, not stored directly by this website.
Calculator Inputs and AI Solver Requests
When you submit a calculator problem or ask for step help, your math input and related context may be sent to a third-party AI or math processing provider so the site can generate an educational response. Do not submit private, confidential, sensitive, or regulated information in calculator inputs.
How We Use Information
We use information to provide calculator results, show explanations, apply free and Premium limits, manage accounts, confirm email addresses, reset passwords, process Premium orders, respond to contact messages, prevent abuse, troubleshoot errors, improve reliability, and protect the website.
Request Logs and Rate Limits
We record technical logs for actions such as page views, calculator requests, step-help requests, rate-limit events, contact messages, and failures. These logs help enforce daily free limits, Premium usage, abuse prevention, diagnostics, and reliability.
Contact Form
If you contact us, we may store your name, email address, subject, message, IP address, browser user agent, and submission time. This helps us respond, prevent spam, and troubleshoot delivery issues.
Cookies and Similar Technologies
The website may use cookies or similar technologies for sessions, CSRF protection, account login, security checks, Cloudflare Turnstile, advertising, and measurement where enabled. See the Cookie Policy for more detail.
Advertising and Analytics
If Google AdSense, Google Analytics, or similar services are enabled, those providers may use cookies or similar technologies according to their own policies and user controls.
Security and Retention
We use reasonable technical measures to protect stored records and limit access. Logs, account records, tokens, orders, and contact messages are kept as long as needed for operation, security, diagnostics, legal compliance, accounting, dispute handling, or communication.
Your Choices
You can disable non-essential cookies through your browser. You may contact us to request review or deletion of contact messages or account information where applicable. Some information may need to be retained for security, accounting, legal, or operational reasons.
