Privacy Policy

Summary

Information We Do Not Collect

This site does not collect:

• Your calculator inputs (grade, step, salary, benefits selections, tax information)
• Your calculator results (net pay, deduction amounts, tax estimates)
• Your name, email address, or any personally identifiable information (unless you voluntarily provide it via the contact page)
• Your Social Security number, Employee ID, or any federal employment identifiers
• Financial account information of any kind

The calculator is a static website. There is no server-side application, no database, and no user accounts. When you close your browser tab, your inputs are gone.

Information Collected Automatically

Like most websites, this site uses standard analytics and advertising services that may collect certain non-personal technical information automatically:

Google Analytics 4 (GA4)

We use Google Analytics 4 to understand how visitors use the site — which pages are visited, how long visitors stay, what devices and browsers are used, and general geographic region (country/state level, not precise location). GA4 uses cookies and collects:

• Pages visited and time on page
• Device type, browser, operating system
• Approximate geographic location (country/region level from IP address)
• Referral source (how you found the site)
• Anonymized interaction events (e.g., "calculator used" — but NOT what inputs were entered)

GA4 does not have access to your calculator inputs or results. Google's privacy policy applies to the data collected by GA4: policies.google.com/privacy.

Google AdSense

This site displays advertisements through Google AdSense. AdSense may use cookies to serve ads based on your prior visits to this and other websites. Google's advertising privacy policy applies: policies.google.com/technologies/ads.

You can opt out of personalized advertising by visiting Google Ads Settings or using the Network Advertising Initiative opt-out page.

Cookies

This site itself does not set any first-party cookies. However, the third-party services described above (Google Analytics, Google AdSense) may set cookies on your device. These are governed by Google's cookie policies.

You can control cookies through your browser settings. Blocking cookies will not affect the calculator's functionality — it works entirely without cookies.

Data Sharing

We do not sell, rent, or share any personal information with third parties. The only data sharing that occurs is through the standard analytics and advertising services described above, which operate under their own privacy policies.

Contact Form

If you use the contact page to send us a message, the information you voluntarily provide (such as your email address and message content) will be used solely to respond to your inquiry. We will not add you to any mailing list or share your contact information with third parties.

External Links

This site contains links to external websites (OPM, IRS, SSA, TSP.gov, state revenue departments, Tax Foundation, etc.) for source citations and reference. We are not responsible for the privacy practices of these external sites. Each operates under its own privacy policy.

Children's Privacy

This site is not directed at children under 13. We do not knowingly collect any information from children under 13. If you believe a child has provided personal information through the contact form, please contact us and we will delete it promptly.

Changes to This Policy

If this privacy policy is updated, the revised version will be posted on this page with an updated effective date. Material changes will be noted at the top of the page.
