Privacy Policy
Last updated: November 12, 2026. Your financial inputs belong to you alone.
1. Overview & Client-Side Architecture
At Online Income Calculator (accessible from incomestackcalculator.com), your privacy is fundamental to our design. This website is engineered as a 100% client-side web application. All mathematical computations, formula evaluations, currency conversions, and reverse goal algorithms are executed directly within your browser's local JavaScript runtime.
2. Financial & Input Data
We do not collect, transmit, store, or sell any numbers, revenue targets, rates, or metrics you enter into our calculator. When you adjust sliders or toggle income streams, that information never leaves your device and is never transmitted across the network to our servers or any third-party databases.
3. LocalStorage Usage
To enhance your user experience, the website utilizes your browser's built-in localStorage mechanism to save your active modules, currency preference, and custom input values. This ensures your customized income stack is restored when you refresh or revisit the page. This data resides solely on your physical device. You can clear this data at any moment by clicking the "Reset to Defaults" button on the calculator or by clearing your browser's site data.
4. Cookies & Web Tracking
We do not use advertising cookies, behavior profiling trackers, cross-site tracking pixels, or third-party marketing beacons.
5. Server Logs
Like virtually all standard web servers, our hosting infrastructure may temporarily log generic HTTP request data (such as IP address, browser user-agent, operating system, and request timestamps) strictly for infrastructure security, DDoS prevention, and server health diagnostics. These basic access logs are never cross-referenced with your calculator inputs.
6. Children's Privacy
Our website is a general audience digital tool. We do not knowingly solicit or collect personal information from individuals under the age of 13.
7. Contact Information
If you have questions or inquiries regarding our privacy practices, please contact us at privacy@incomestackcalculator.com.
