This Cookie Policy explains how Madre Fertility LLC ("Madre," "we," "us," or "our") uses cookies and similar technologies on https://www.madrefertility.com (the "Site") and our related mobile and web applications (collectively, the "Services").

This policy should be read alongside our Privacy Policy.

1. What are cookies?

Cookies are small text files placed on your device when you visit a website. They help websites remember your preferences, keep you logged in, and understand how you use the site. Similar technologies — including localStorage, sessionStorage, and device identifiers — work in comparable ways and are also covered by this policy.

Cookies can be:

First-party: set by Madre directly
Third-party: set by external services we use (e.g. analytics providers)
Session cookies: deleted when you close your browser
Persistent cookies: remain on your device for a set period

2. How we use cookies

We use cookies and similar technologies for the following purposes:

To keep you securely logged in and protect your account
To remember your preferences and personalize your experience
To understand how users interact with our Services so we can improve them
To measure the effectiveness of our marketing (where consent is given)
To manage your cookie consent preferences

3. Cookie categories

5. Your consent and choices

When you first visit the Site from the United Kingdom or Canada, you will see a cookie consent banner. You can choose to accept all cookies, reject non-essential cookies, or customize your preferences by category.

For users in the United States, strictly necessary cookies are used by default. Non-essential cookies (analytics and marketing) may also be active. You can adjust your preferences at any time using the link below or in the footer of the Site.

Your preferences are stored for 12 months. After that period, we will ask for your consent again.

Please note:

Rejecting analytics cookies means we cannot track how you use the Services to improve them.
Rejecting marketing cookies means our ads may be less relevant to you, but you will still see ads.
Strictly necessary cookies cannot be disabled as the Services require them to function.

6. Managing cookies in your browser

You can also control cookies directly through your browser settings. Most browsers allow you to view, delete, and block cookies. Note that blocking all cookies may affect the functionality of the Services, including your ability to stay logged in.
