Last Updated: January 5, 2026

This Privacy Policy describes how StemSplit ("we," "us," or "our") collects, uses, and shares information about you when you use our website, applications, and services (collectively, the "Services"). By using our Services, you agree to the collection and use of information in accordance with this policy.

We collect information you provide directly to us, including:

Google Analytics collects the IP address assigned to you on the date you visit our site, rather than your name or other identifying information. We do not combine information collected through Google Analytics with personally identifiable information.

Google's ability to use and share information collected by Google Analytics about your visits to our site is restricted by the Google Analytics Terms of Service and the Google Privacy Policy.

You can opt-out of Google Analytics by installing the Google Analytics Opt-out Browser Add-on.

We use Google Ads to display advertisements across the Google Display Network and in Google search results. Google may use cookies to serve ads based on your prior visits to our website or other websites.

Measure conversions from Facebook and Instagram ads
Build targeted audiences for future ads
Remarket to people who have already taken actions on our website

You can control your ad preferences on Facebook by visiting your Facebook Ad Preferences.
