• Collect, store, or process your personal or financial information on our servers
• Require you to create an account or provide identifying details
• Save your income data, custody information, or calculation results
• Share any user-specific data with third parties
• Track individual calculation results or outcomes

The data you enter into our calculators remains entirely in your browser and is never transmitted to our servers or any third-party service.

When you visit our Site, certain information may be collected automatically through standard web technologies. This may include:

• IP address (anonymized where possible)
• Browser type and version
• Operating system
• Referring website or URL
• Pages visited and time spent on the Site
• Device type (desktop, mobile, tablet)
• General geographic location (country/region level only)

You can control cookies through your browser settings. Most browsers allow you to block or delete cookies. Please note that disabling cookies may affect certain features of the Site.

We use the following third-party services that may collect information as described below:

We do not share any personal data with these third-party services, as we do not collect personal data in the first place.

We take reasonable measures to protect the security of our Site and any data processed through it. Our security practices include:

• Client-side-only calculation processing — no sensitive data is transmitted over the internet
• Regular review of our technology stack for vulnerabilities
• Minimal data collection by design

However, no method of electronic transmission or storage is 100% secure. While we strive to protect any information, we cannot guarantee absolute security.

Our Site is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will take steps to remove that information.
