Privacy Policy

Last updated: June 20, 2026

At QuillCalc, we take user privacy extremely seriously. This Privacy Policy describes how your data is handled when you use our website (https://quillcalc.com) and its tools.

1. No Server-Side Processing of Tool Data

The core philosophy of QuillCalc is client-side execution. Whether you are generating passwords, calculating payroll taxes, formatting JSON files, or entering weight metrics, all calculations are performed locally in your web browser.

We do not collect, transmit, or store any of the content or values you type into our input fields, text areas, or file dropzones.

2. Local Storage

Some tools (like the BMI Calculator or paycheck preferences) allow you to save your results to keep track of your history. If you opt to use these features, the data is saved in your browser's local storage (LocalStorage). This data never leaves your device and can be cleared by you at any time via the tool controls or by clearing your browser cache.

3. Advertisements

We use third-party advertising services (such as Google AdSense) to serve advertisements when you visit our website. These companies may use cookies and non-personally identifiable information about your visits to this and other websites in order to provide advertisements about goods and services of interest to you.

4. Analytics

To understand user traffic and page view performance, we may use standard privacy-respecting analytics solutions. These metrics do not collect or monitor data entered into tools.

5. Contact

If you have any questions or concerns about this policy, please feel free to reach out to us.
