隱私權政策

我們收集的資訊

Weight Scale 的設計以隱私為核心。我們僅收集最少的資料以提供服務：

• Anonymous Authentication: We use Firebase Anonymous Authentication to create a unique identifier for your device. No personal information (name, email, phone number) is collected.
• Scan Counter: We maintain a count of scans performed per anonymous user ID in Firebase Firestore. This is used solely to enforce free-tier limits.
• Camera Images: When you scan an object, the photo is sent to Google's Gemini API via a Firebase Cloud Function for weight estimation. Images are processed in real-time and are NOT stored on our servers.
• Analytics: We use PostHog for anonymous usage analytics and session recording to improve the app experience. No personally identifiable information is tracked.
• Error Monitoring: We use Sentry to capture error logs for debugging purposes. No personal data is included in error reports.

我們如何使用您的資訊

我們將收集到的有限資料用於：

• Provide AI-powered weight estimation via the Gemini API
• Enforce free-tier scan limits (3 free scans)
• Improve app performance and fix bugs
• Understand anonymous usage patterns to improve the product

第三方服務

Weight Scale 使用以下第三方服務：

• Firebase (Google) — Anonymous authentication and Cloud Functions for Gemini API proxy
• Google Gemini API — AI image processing for weight estimation
• PostHog — Anonymous analytics and session recording
• Sentry — Error monitoring and crash reporting
• Apple StoreKit 2 — Subscription payment processing (handled entirely by Apple)

資料共享

我們絕不會向第三方出售、交易或共享您的個人資料。我們不提供廣告服務。唯一傳輸給第三方的資料是發送至 Google Gemini API 進行處理的相機影像，該影像不會被儲存。

兒童隱私

Weight Scale 不會刻意收集 13 歲以下兒童的個人資訊。由於我們使用匿名驗證且不收集任何個人資料，因此本 App 適合所有年齡層使用。
