# Privacy Policy

_Last updated: August 2026_

At Modern Stamina, accessible from modernstamina.com, your privacy is a priority. This Privacy Policy outlines the types of information we collect and record and how we use it.

## 1\. Information We Collect

We only collect information necessary to provide our services and improve your experience. This includes:

  * **Email Addresses:** If you choose to contact us or subscribe to future newsletters, we collect your email address.
  * **Usage Data:** We may collect non-personally identifiable information automatically through cookies and analytics tools to understand how visitors interact with our website.

## 2\. Quiz and Calculator Data

The Modern Stamina Quiz and our calculators operate entirely client-side. Here is how we handle this data:

  * **What is collected:** The 12 quiz inputs \(covering your movement, nutrition, sleep, and lifestyle habits\) and calculator inputs \(such as height, weight, age, and activity level\).
  * **Storage:** We do not store your inputs on our servers. All data is processed and stored locally in your browser using `localStorage`.
  * **Retention:** Your data remains in your browser's local storage until you manually clear it or retake the quiz/recalculate your results.
  * **Email Association:** Quiz and calculator results are never associated with your email address or any personally identifiable information.
  * **Deletion:** You can delete your quiz and calculator data at any time by clearing your browser's site data or local storage for modernstamina.com.

## 3\. Analytics and Tracking

To improve our content and user experience, we track specific anonymous events on our website. These include:

  * `quiz_started` and `quiz_completed`
  * `result_category` \(your overall tier label from the quiz, but **not** your raw inputs\)
  * `quiz_retake`
  * `calculator_started` and `calculator_completed`
