The yzhstudio.com website does not:
- Set tracking cookies

App-Specific Privacy Policies
Each app published by YZH Studio has its own dedicated, comprehensive privacy policy:
Analytics, Ads & Data Boundary Transparency
We believe in complete transparency regarding how our free apps function, how metrics are collected, and how user content is isolated:
- 100% On-Device Personal Database: All your personal data (saved links, bookmarks, AI summaries, custom tags, shopping comparisons, and prices) lives exclusively in local SQLite on your physical device and never touches our servers or third parties.
- Google Firebase Analytics & Crashlytics: We use Firebase to understand aggregate app usage (such as app open frequency, screen views, feature adoption, and crash diagnostics) to maintain stability and improve product quality.
- Google AdMob: We use Google AdMob to monetise our free apps using Non-Personalised Ads (NPA) and GDPR/CCPA user consent dialogs. Standard technical signals (such as device IP for fraud prevention and geo-routing) are processed by Google.
- Strict Content Isolation: Neither Google Firebase nor Google AdMob has access to the contents of your SQLite database, bookmarks, search queries, or price calculation records.
AdMob Publisher Verification
YZH Studio uses Google AdMob (publisher ID: pub-8504468769013902) to monetise our free Android applications. The app-ads.txt and ads.txt files on this domain are used for authorised seller verification as required by the IAB Tech Lab standards.
