This Privacy Policy describes how Attendance Calculator ("we", "us", or "our") collects, uses, and discloses information when you use https://attendancecalculator.org (the "Service"). By using the Service, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

The core attendance calculator runs entirely in your browser. Numbers you enter (classes held, attended, subject names) are not transmitted to or stored on our servers — all calculations and PDF generation happen locally on your device.

If you contact us via the Contact page, we collect the name, email address, and message content you voluntarily provide, solely to respond to your inquiry.

2. Cookies and Tracking Technologies

We use cookies and similar tracking technologies to track activity on our Service and store certain information. You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent.

3. Third-Party Advertising (Google AdSense)

We use Google AdSense to display advertisements on this Service. Google, as a third-party vendor, uses cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to our site and/or other sites on the Internet.

You may opt out of personalized advertising by visiting Google Ads Settings. For more information on how Google uses data, visit Google's Partner Sites policy.

4. Analytics

We may use third-party analytics services (such as Google Analytics) to monitor and analyze use of our Service. These services may use cookies and similar technologies to collect and analyze information about use of the Service.

5. Data Security

We value your trust in providing your information, and we strive to use commercially acceptable means of protecting it. However, no method of transmission over the Internet is 100% secure.

6. Children's Privacy

Our Service does not knowingly collect personally identifiable information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us so we can take appropriate action.
