TrueStamp Timestamp Camera (hereinafter referred to as "the App") is developed and operated by ImL1s (hereinafter referred to as "we" or "us"). We highly value your privacy, and this Privacy Policy aims to explain how we collect, use, and protect your personal information.

1. About the App

This App is a professional timestamp camera application that automatically adds time, location, GPS coordinates, weather, and other information as watermarks when taking photos. It is suitable for construction site documentation, insurance claims evidence, news reporting, and other scenarios requiring proof of time.

2. Data Collection and Use

To provide complete functionality and services, this App may collect or use the following information:

• Account Data: If you choose to use Google Sign-In or Apple Sign-In, we will obtain your basic account information (such as email address and display name) through Firebase Authentication to provide account synchronization and cloud backup features.
• Location Data: This App requires access to your location to display address and GPS coordinates in photo watermarks. Location information is only read when taking photos and is not continuously tracked.
• Camera & Photos: This App requires access to the camera for taking photos and access to the photo library to save or read photos. Photo data is only stored locally on your device or in cloud storage of your choice.
• Weather Data: If you enable the weather watermark feature, the App will send queries to third-party weather APIs based on your location to retrieve current weather information.
• Team & Project Data: If you use the team feature, your team information, project data, and related photos will be stored in Firebase Firestore and Firebase Storage to provide team collaboration and data synchronization features.
• Device & Log Data: When the App encounters errors or crashes, we may collect crash-related log data (via Google Firebase Crashlytics), including device model, operating system version, and time of error occurrence, to help fix issues.
• Usage Data: We use Google Firebase Analytics to collect anonymous usage data (such as page views and feature usage frequency) to analyze user behavior and optimize the App experience.
