Privacy Policy

Last Updated: December 31, 2025

1. Information We Collect

1.1 Calculator Data (Not Collected)

All calculations are performed locally in your browser. We do not collect, store, or transmit any numbers or values you enter into the calculator. Your calculation data never leaves your device.

1.2 Contact Form Information

When you use our contact form, we collect:

• Name: To address you in our response
• Email Address: To respond to your inquiry
• Subject: To categorize your message
• Message Content: To understand and respond to your inquiry

This information is sent directly to our email address (admin@calculatepercentageincrease.com) via your email client using the mailto protocol. We do not store this information on any server.

1.3 Browser Storage (localStorage)

Our calculator uses your browser's localStorage feature to:

• Save your recent calculation history (optional feature)
• Remember your calculator preferences (if any)

Important: This data is stored locally on your device only. We cannot access this data, and it never leaves your browser. You can clear this data at any time using the "Clear History" button or your browser's settings.

4. Cookies

We do not use cookies. Our website does not set any cookies for tracking, analytics, or any other purpose.

5. Data Security

5.1 Calculator Security

Since all calculations are performed in your browser using JavaScript, there is no transmission of calculation data to our servers. This provides inherent security as your calculation data never leaves your device.

5.2 Email Security

Contact form submissions use the mailto protocol, which relies on your email client's security. We recommend using encrypted email services for sensitive communications.

Email communications are retained only as long as necessary to respond to your inquiry and provide support. Typically, this is 30-90 days unless ongoing communication is required.

7.2 Calculator Data

We do not retain any calculator data. Data stored in your browser's localStorage remains until you clear it or until your browser automatically clears it based on your settings.

8. Children's Privacy

Our calculator is suitable for all ages, including children. We do not knowingly collect personal information from children under 13. Since our contact form does not collect age information, we recommend that children under 13 have parental permission before submitting contact forms.
