Part II: User Service Agreement (Global Compliance Upgrade)

This User Service Agreement is entered into between our professional mobile app R&D team ("we", "our team") and you ("user", "you"), and applies to all your behaviors when using our application products and related services globally. Products may be distributed through App Store, Google Play, and other compliant channels. This agreement is adapted to global legal frameworks, application distribution policies, and monetization platform requirements.

I. Agreement General Rules

1.1 Agreement Scope

This agreement is the legal agreement between us and you regarding usage of all application products and services (collectively "Services"). It applies globally and aligns with App Store/Google Play terms, monetization platform rules, and applicable laws including but not limited to cybersecurity, e-commerce, and consumer protection requirements in relevant jurisdictions.

1.2 Acceptance

By downloading, installing, or using any Application Product, you confirm that you have fully read, understood, and voluntarily accepted this User Service Agreement, the Privacy Policy, and additional in-app rules (including ad rules and in-app purchase rules). If you do not agree with any provision, do not download, install, or use the product.

1.3 Agreement Updates

We may update this agreement based on legal updates, platform policy changes, monetization partner requirements, service optimization, or regulatory developments. Updates will be announced by popup, push notification, or in-app notice. Continued use means acceptance of updated terms.

II. Service Content and Scope

We provide complete functional services for local utility and efficiency scenarios and continuously optimize stability, fluency, and quality.

2.2 Monetization-Related Services

• IAA Advertising Services: compliant ad display such as app open ads, interstitial ads, banner ads, and rewarded video ads. Ad content is supplied by compliant third-party platforms and subject to review under legal and store policy requirements.

Additional services may include customer support, issue troubleshooting, version updates, feature optimization, and product usage guidance.
