Cookie Policy

Last updated: April 2026

This Cookie Policy explains how MuscleGuard (“we,” “us,” or “our”) uses cookies and similar technologies when you use our wellness tracking application (the “Service”). This policy is part of our Privacy Policy.

1. What Are Cookies

Cookies are small text files that are placed on your device (computer, tablet, or mobile phone) when you visit a website. They are widely used to make websites work more efficiently, provide a better user experience, and give website operators information about how the site is being used.

2. Cookies We Use

MuscleGuard uses a minimal set of cookies, limited to what is necessary for the Service to function properly. We categorize our cookies as follows:

Strictly Necessary Cookies (Authentication)

These cookies are essential for the Service to function. They enable you to log in, stay authenticated, and access your account securely. Without these cookies, the Service cannot operate.

Cookies We Do Not Use

MuscleGuard does not use:

  • Advertising or tracking cookies: We do not serve ads, and we do not use cookies to track your activity across other websites.
  • Analytics cookies: We do not currently use third-party analytics cookies (such as Google Analytics).
  • Social media cookies: We do not embed social media widgets that set cookies.
  • Third-party marketing cookies: We do not share cookie data with advertising networks or marketing platforms.

3. How to Manage Cookies

You can manage cookies through your browser settings. Most browsers allow you to:

  • View what cookies are stored on your device.
  • Delete individual cookies or all cookies.
  • Block cookies from specific or all websites.
  • Set preferences for first-party vs. third-party cookies.

Instructions for managing cookies in common browsers:

  • Chrome: Settings > Privacy and security > Cookies and other site data
  • Firefox: Settings > Privacy & Security > Cookies and Site Data
  • Safari: Preferences > Privacy > Manage Website Data
  • Edge: Settings > Cookies and site permissions > Cookies and site data

Please note that if you block or delete the authentication cookies used by MuscleGuard, you will be logged out and will need to sign in again.

4. Changes to This Cookie Policy

We may update this Cookie Policy from time to time to reflect changes in our practices or for operational, legal, or regulatory reasons. We will post any changes on this page and update the “Last updated” date. If we begin using additional types of cookies (such as analytics), we will update this policy and notify you accordingly.
