Effective Date: May 21, 2026

Welcome to PIAN 片 ("the App"). By using the App, you agree to these terms.

Service Overview

PIAN 片 is an AI-assisted Chinese learning tool: users describe a scenario, and the AI generates relevant Chinese words, phrases, and sentences. The App requires no account registration and operates no servers.

Free Tier, Ads & Pro

Free users receive a limited number of AI scenario generations. When the free quota is exhausted, you may optionally watch a rewarded video ad to unlock one additional generation. Ads are never shown during study, onboarding, or checkout. Pro subscribers do not see ads.

Ads are served by Google AdMob. Where required by law (e.g. EEA/UK), we show Google's consent form before ads. On iOS we may ask for App Tracking Transparency permission for more relevant ads; you can decline and still use the app. Ad privacy choices can be changed in Profile → Ad privacy choices when available.

Subscriptions & Auto-Renewal

The App offers monthly and yearly auto-renewing Pro subscriptions:

• Payment will be charged to your Apple Account upon purchase confirmation.
• Subscriptions auto-renew unless auto-renewal is turned off at least 24 hours before the current period ends.
• Your account will be charged for renewal within 24 hours before the current period ends.
• Manage or cancel anytime in your Apple device's Settings → Apple Account → Subscriptions.
• Any unused portion of a free trial will be forfeited upon subscription purchase.

User Conduct

You may not reverse engineer, disrupt the App's operation, or use the App for illegal activities.

Disclaimer

The App is provided "as is." AI-generated content is for learning reference only.
