Privacy Policy
Effective date: October 24, 2026
Prized (如数家珍) is a private-museum app for collectors, developed by Shanghai Shoumeng Jiaye Technology Co., Ltd. This policy explains how information is handled when you use Prized. Prized runs fully on-device: your collection photos and data stay on your device by default; we operate no backend servers.
Core principle
Your collection belongs to you. · Fully on-device: photos, cutouts and records never leave your phone · No accounts: we collect no email, phone, or identity info · You own your backups: exports are files you keep yourself
Contents
1. Information We Collect
1. Collection data you create (photos, names, tags, dates, costs and values, notes) is stored only on your device and never uploaded to any server. 2. Prized has no account system, so we collect no email, phone number, or other identity information. 3. Purchases are handled entirely by Apple; we only receive a local unlock confirmation on your device.
2. How Information Is Used
Collection data is used solely to render the app's features on your device: the display shelf, exhibitions, statistics, annual reports and anniversary reminders. We do not profile, analyze, or sell any user data.
3. Photos and Cutouts
Camera and photo library permissions are requested only when you actively shoot or pick photos for a collection piece. Subject cutout processing runs on the device using Apple's Vision framework (or Google ML Kit on Android). Photos are never uploaded or transmitted anywhere.
4. Storage and Security
All data lives in a local database inside the app's sandbox on your device. You can export a full backup file (.db) or a CSV from Settings - Backup & Export; these files are yours to keep. Deleting the app removes all data permanently.
5. Notifications
Prized can schedule local anniversary reminders (for example, "one year ago today") using the system notification service. Reminders are generated on your device and never involve a server. You can disable them at any time in the system settings.
6. Purchases
Prized Pro is offered as subscriptions or a one-time purchase through the App Store. Payment, billing and refunds are processed by Apple under its own privacy policy. We receive no financial information; entitlement status is stored only on your device.
7. Third-Party Services
Prized integrates Firebase Crashlytics solely to collect crash and error diagnostics so we can find and fix problems. Crash data is not linked to your identity and never includes your collection contents. No analytics, advertising, or other third-party data-collection SDKs are integrated. The only other external service is an App Store purchase you initiate yourself.
8. Minors
Prized is intended for general users. If you are a minor, please use the app and make purchases under guardian supervision.
9. Your Rights and Contact
Because all data lives on your device, you can view, export or delete everything at any time — uninstalling the app deletes it all. Questions about this policy: tzhh0617@gmail.com. We typically reply within 1–3 business days.
