Privacy Policy

Last Updated: February 28, 2026

Welcome to Stamp Journal. We respect your privacy and are committed to protecting it through our compliance with this policy. This Privacy Policy outlines how we collect, use, and safeguard your information when you use our mobile application.

1. Information We Collect

A. User Content (Images & Prompts): When you create stamps using your own photos, the image processing primarily happens locally on your device. However, when you use the AI Magic Sketchbook feature, the text prompts you enter are sent to our external AI provider (FAL) to generate images. We do not permanently store or claim ownership of your images or prompts.

B. Usage and Device Data: We use Firebase Analytics to understand how users interact with our app. This includes anonymous device identifiers, app activity, crash reports, and performance data. This helps us fix bugs and improve the app. This data does not personally identify you.

C. Purchase Information: If you purchase a premium subscription, the transaction is processed securely through Apple's App Store and tracked via RevenueCat. We do not have access to your credit card information. RevenueCat assigns an anonymous user ID to provide you with your purchased entitlements.

2. Third-Party Services We Use

We employ third-party companies to facilitate our service:

3. Data Retention and Security

All locally created journals and stamps are stored directly onto your device's local storage or your personal iCloud account (if enabled). We do not have a central database of your private journals. Analytics and purchase validation data held by Firebase and RevenueCat are secured according to their respective strict industry-standard privacy policies.
