Privacy Policy

1. In-Browser Client-Side Processing

At Percentage Difference Calculator (percentagedifference.com), your privacy is protected by design.

All numbers, mathematical inputs, precision settings, and calculation traces run strictly in your web browser memory. We never transmit, store, or log your numerical entries to any remote server or third-party database.

2. Information We Do Not Collect

• No User Account: No signup, registration, password, or profile information is ever requested.
• No Calculation Storage: Calculation history remains private to your local browser tab and disappears upon closing.
• No Invasive Tracking: We do not deploy fingerprinting or invasive session-recording scripts.

3. Clipboard API Interaction

The website provides a "Copy Result" button. When activated by your click, it utilizes the standard HTML5 Clipboard API to copy the calculated percentage to your operating system clipboard. We do not read or inspect your clipboard contents.

4. Standard Hosting Telemetry

Like all web properties, requests to our static hosting network generate standard technical logs (such as IP address, user-agent string, operating system, and request time) strictly to route HTTP traffic, defend against automated DDoS attacks, and preserve service availability.

5. Inquiries & Contact

If you have questions regarding our privacy practices, please contact us via email at [email protected] or visit our Contact page.
