Privacy Policy

Calculator Input Handling

The calculator does not submit the values you enter to an application server for calculation or storage. These values include:

• Your salary or income amount
• Your state of residence
• Your filing status
• Pre-tax deductions or withholding elections
• Any other inputs or calculation results

Calculations are performed in your browser. If you explicitly create or open a shared calculation link, its inputs are encoded in the URL and may be visible to the recipient, the hosting provider handling the page request, and your browser history.

How the Calculator Works

When you visit NetPayCalculator.app:

1. Your browser downloads the HTML, CSS, and JavaScript code that powers the calculator.
2. All tax calculations happen locally on your device using that code.
3. Calculator inputs are not submitted to an application API.
4. Your theme preference is stored locally; calculation inputs are not saved in local storage.

Shareable Calculation Links

You can share a calculation by copying the URL from your browser. When you do this:

• Your inputs are encoded as URL parameters (the part of the URL after the "?")
• These parameters remain in the URL and may appear in CDN request logs or browser history
• Anyone with the link can see those parameters in the URL and the resulting calculation
• Only share calculation links with people you trust, as they contain the values you entered

Website Analytics

We use Google Analytics to understand aggregate site usage, such as page views and popular pages. Analytics is configured to report the page path without query parameters so shared calculation values are not included in the reported page URL. Google Analytics processes standard technical information according to Google's own policies.

We do not use:

• Session replay or heatmap tools
• Any form of behavioral tracking tied to your personal inputs

Browser Local Storage

The calculator uses your browser's local storage to remember:

• Your theme preference (light or dark mode)
• No other data is stored locally

This data stays entirely on your device and is never transmitted to us. You can clear it at any time through your browser settings.

Hosting and Security

NetPayCalculator.app is hosted on a content delivery network (CDN) that may collect standard server logs, which typically include:

• IP address
• Request timestamp
• Requested URL, which can include query parameters in a shared calculation link
• Browser user agent string

These logs are maintained by the hosting provider for operational and security purposes and are not accessible to us for analysis or identification of individual users.

The site is served over HTTPS to ensure any data transmitted between your browser and our servers is encrypted.

Third-Party Services

The calculator itself runs in your browser and does not submit its form values to a calculation API. We use Google Analytics for aggregate site usage statistics and remove query parameters from the page location sent during initialization. We also use Google AdSense for advertising, which may use cookies for ad personalization. You can opt out of personalized ads via Google's Ad Settings.

Children's Privacy

NetPayCalculator.app is designed for adults planning their finances. We do not knowingly solicit information from children under 13. Calculator values are not submitted to a calculation API, but contact and feedback forms can collect information a person chooses to provide.
