Privacy Policy

Last updated: March 20, 2026

Introduction

GrainHeads ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how our iOS application handles your information.

Information We Collect

GrainHeads does not collect, store, or transmit any personal information such as your name, email address, or location. However, we do collect anonymous usage and crash data through Firebase (see below) to help us improve the app.

Third-Party Services

GrainHeads uses the following third-party services:

Firebase Analytics

We use Firebase Analytics to collect anonymous usage data, such as how often the app is opened, which features are used, and general engagement metrics. This data does not include any personally identifiable information and is used solely to help us understand how users interact with GrainHeads so we can improve the experience. You can review Firebase's Privacy Policy for more details.

Firebase Crashlytics

We use Firebase Crashlytics to collect anonymous crash reports and diagnostic data when the app encounters an error. This includes information such as device type, operating system version, and stack traces. Crashlytics does not collect personally identifiable information. This data helps us identify and fix bugs to improve app stability.

RevenueCat

We use RevenueCat to manage in-app purchases. GrainHeads offers a one-time purchase to unlock the full app. RevenueCat processes this transaction and may collect anonymous purchase-related data (such as transaction identifiers) as required by Apple's App Store. RevenueCat does not collect personal information on our behalf. You can review RevenueCat's Privacy Policy for more details.

In-App Purchases

GrainHeads offers a single one-time purchase. All payment processing is handled by Apple through the App Store. We do not have access to your payment information.

Data Storage

All your samples, presets, and app settings are stored locally on your device. We do not have access to this data and it is never transmitted to any server.

Children's Privacy

GrainHeads does not knowingly collect any information from children under the age of 13.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date.
