Privacy Policy

Effective Date: March 15, 2026 Last Updated: March 15, 2026

Introduction

HalfLife LLC ("we," "our," or "us") operates the HalfLife mobile application (the "App"). This Privacy Policy explains how we handle information in connection with your use of the App.

Information We Collect

We do not directly collect any personal information from users of the App. HalfLife is designed to function as a pharmacokinetic tracking and visualization tool without collecting, storing, or transmitting personal data to our servers.

Third-Party Services

While we do not collect data ourselves, certain third-party services integrated into the App may collect limited data as part of their normal operation.

RevenueCat

We use RevenueCat to manage in-app subscriptions and purchases. RevenueCat may collect and process the following data on our behalf:

• Purchase history and subscription status

• Device identifiers

• App usage data related to subscription events

This data is collected and processed by RevenueCat in accordance with their Privacy Policy, which can be reviewed at https://www.revenuecat.com/privacy. We do not have direct access to or control over the data RevenueCat collects beyond what is necessary to manage your subscription.

In-App Purchases & Subscriptions

HalfLife offers paid subscription options. All payments are processed exclusively through Apple's in-app purchase system. We do not collect, store, or have access to your payment information. All billing and payment data is handled by Apple in accordance with their Privacy Policy at https://www.apple.com/legal/privacy.

Data Sharing

We do not sell, trade, or otherwise transfer your information to third parties. No personal data collected by us is shared with outside parties because we do not collect personal data in the first place.

Children's Privacy

The App does not knowingly collect personal information from children under the age of 13. Since we collect no personal data from any users, no special handling is required. If you believe a child has provided personal information through the App, please contact us and we will take appropriate steps.

Your Privacy Rights

Since HalfLife does not collect personal data, there is no personal data to access, correct, or delete on our end. For any data collected by RevenueCat in connection with your subscription, you may contact RevenueCat directly at https://www.revenuecat.com/privacy.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. Continued use of the App after any changes constitutes your acceptance of the revised policy.
