Privacy Policy
Last updated: September 29, 2026
At NetPayCalculator.app, your privacy is fundamental to how we operate. This policy explains our privacy-first approach and what minimal data, if any, we collect when you use our calculator.
No Data Collection
We do not collect, store, or transmit any of the information you enter into the calculator. This includes:
- Your salary or income amount
- Your state of residence
- Your filing status
- Pre-tax deductions or withholding elections
- Any other inputs or calculation results
All calculations are performed entirely in your web browser. Nothing leaves your device unless you explicitly share a calculation link with someone.
How the Calculator Works
When you visit NetPayCalculator.app:
- Your browser downloads the HTML, CSS, and JavaScript code that powers the calculator.
- All tax calculations happen locally on your device using that code.
- No information is sent to our servers or any third-party services.
- When you close the page, nothing is saved unless you've explicitly bookmarked a calculation link.
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 are not stored on our servers
- 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
No Analytics or Tracking
We do not use:
- Google Analytics or similar analytics services
- Advertising networks or tracking pixels
- Third-party cookies
- Session replay or heatmap tools
- Any form of behavioral tracking
We cannot see how many people visit the site, which states are selected, or what salary ranges are calculated.
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.
Feedback and Contact
When you submit feedback through our feedback form or email us directly:
- We collect only what you choose to share (your message and optional email address)
- This information is used solely to respond to your inquiry or feedback
- We do not share your contact information with third parties
- We retain messages only as long as necessary to resolve your issue or answer your question
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 (without query parameters in most cases)
- 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
We do not integrate any third-party services that collect user data. The calculator operates entirely as a standalone web application.
Children's Privacy
NetPayCalculator.app is designed for adults planning their finances. We do not knowingly collect information from children under 13. Given our privacy-first approach, we collect no personal information from anyone, including children.
Changes to This Policy
If we ever change our privacy practices, we will update this policy and note the revision date at the top of this page. Significant changes will be announced prominently on the homepage.
