Introduction

Gritworks ("we", "us") respects your privacy and is committed to protecting the personal information of users of FourCut (the "App").

Information We Collect

The App may collect the following information:

• Camera & Photo Access: We access your camera and photo library for 4-cut photo capture and stamp creation. Photos are processed locally on your device and are not sent to external servers, except when you use QR sharing.
• Usage Data: We collect anonymous usage statistics through Firebase Analytics to improve the App.
• Crash Reports: We collect technical crash data through Firebase Crashlytics to identify and fix issues.
• Purchase Information: In-app purchase transactions are processed through RevenueCat.
• QR Sharing: When using the QR share feature, photos are temporarily uploaded to Firebase Storage and automatically deleted after 24 hours.

How We Use Information

• To provide and improve App functionality
• To detect and fix bugs
• To process in-app purchases
• To enable temporary photo sharing via QR codes

Third-Party Sharing

We do not share your information with third parties except as required by law or with your consent.

Data Storage

Strips, stamps, frames, and other data saved within the App are stored only on your device. There is no cloud backup. Deleting or reinstalling the App will permanently remove this data. We recommend saving important work to your Photos app separately.

Photos uploaded via QR sharing are automatically deleted after 24 hours.
