1. Commitment to Privacy

At PercentageIncreaseCalculator.com, we are deeply committed to protecting your privacy online. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information when you visit and interact with our Website.

2. Information We Collect

We operate under a privacy-first model:

  • Calculator Inputs: Numbers entered into our percentage calculator tools are processed entirely in your web browser (client-side). Your financial data and raw numbers are never sent to, logged by, or stored on our servers.
  • Technical Log Data: Like most web platforms, our servers automatically log standard non-personally identifiable request metadata (IP address, browser type, operating system, referring URL, time stamps) for server diagnostics and DDoS defense.
  • Contact Form Data: If you voluntarily send us a message via our contact form, we collect your name, email address, and message contents solely to respond to your inquiry.

3. How Information Is Used

Non-personal technical data is used exclusively to:

  • Maintain server security, performance, and uptime.
  • Diagnose technical bugs or browser rendering issues.
  • Analyze aggregated traffic patterns to improve site navigation and usability.

4. Cookies & Local Storage

We use essential cookies and local storage tokens to remember user preferences (such as your preferred language selection). We do not use intrusive tracking cookies or cross-site fingerprinting technologies.

You can manage or disable cookies at any time through your browser settings. Note that disabling cookies will not affect your ability to calculate percentages on our site.

5. Analytics & Third-Party Services

We may utilize privacy-respecting analytics services to monitor site performance. These services capture anonymized metrics (such as pageview counts and load times) without storing personal identity profiles.

6. Your Data Rights (GDPR & CCPA)

Under regulations such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), you have rights regarding your data:

  • Right to know what data is collected.
  • Right to request deletion of personal information submitted via contact forms.
  • Right to opt out of non-essential cookies.

7. Children's Privacy (COPPA)

Our website provides educational mathematical tools accessible to students of all ages. We do not knowingly solicit or collect personally identifiable information from children under the age of 13 in compliance with COPPA regulations.

8. Security Safeguards

We employ industry-standard HTTPS/SSL encryption to secure all data transmissions between your browser and our servers.
