Terms of Service

1. IAA Monetization: Real User & Anti-Fraud Rules

IAA (In-App Advertising) is a core monetization method of software services. Any behavior that disrupts ad delivery fairness, harms advertisers' legitimate interests, or circumvents ad platform rules by non-compliant means is considered fraud. The following detailed anti-fraud rules are established based on common fraudulent practices, with corresponding penalty measures.

1.1 Prohibited Ad Interaction Fraud

• Machine-Forced Clicks: Simulating ad clicks through scripts, automated tools, virtual devices, click farms, or click traffic exchange platforms to generate false advertising revenue. Penalty: Permanent account ban, confiscation of all fraudulent gains, and legal action.
• Invisible Click Layer (Clickjacking): Overlaying transparent buttons or invisible clickable zones on the app interface to induce user misoperation or forced clicks on hidden ad elements. Penalty: Permanent account ban, confiscation of all fraudulent gains. Illegal revenue recovery pursued. Legal action for damages.
• Malicious Misleading Clicks: Disguising ad elements as essential functional buttons; manually manipulating ad element positions so that ads appear where functional buttons are expected, or substituting ad elements for functional buttons when the user intends a functional operation. Penalty: Warning ± revenue deduction on first offense. Permanent ban on subsequent offenses.

1.2 Prohibited Ad Fill Rate & Display Fraud

• Forced Passive Refresh: Background automated refresh of ad positions without user awareness; bundling multiple ad positions on a single page to unrealistically inflate ad impressions. Penalty: Warning ± revenue deduction. Multi-time offenders face permanent ban.
• Impersonation of Ad Request Traffic: Using technical means to forge ad request parameters (device model, IP address, carrier information, user agent); placing multiple non-functional ad positions on a single page; falsifying data traffic during nighttime or low-usage periods to simulate high-value users. Penalty: Once detected: immediate permanent account ban, forfeiture of all illegal gains. Serious cases referred to law enforcement.
• Invisible Ad Stacking: Stacking multiple ad positions within the same screen area with only one visible; adding non-functional white dot/small icon ad positions that are invisible to users but functional for ad delivery. Penalty: Immediate permanent ban. Legal action pursued. No negotiation.

1.3 Prohibited Reward Ad & Incentive Fraud

• Falsely Enticing Ad Viewing: False promises of ad rewards — promising in-app benefits but rewarding only after purchasing paid items or spending additional paid time beyond reward viewing. Penalty: Warning ± revenue deduction. Forced removal of related promotional content.
• Coerced Ad Viewing: Forcing users to view specific ads or achieve specific metrics to continue using the app; using time-based or progress-based locking: "consume X ads / watch X seconds to continue" for all features. Penalty: Warning. Correction deadline imposed. Penalty escalation upon recurrence with possible permanent ban.
• Malicious Reward Mechanism: Displaying ads under the pretext of "reward before function access" — requiring mandatory ad viewing before the first use of all features, or setting non-existent rewards to induce fraud. Penalty: Warning. Second violation: immediate permanent ban.
• Improper Reward Delivery: Viewing duration insufficient to trigger reward; reward not delivered or delivered significantly less than promised; awarding only virtual items without practical function; delivering rewards but with disproportionate consumption costs. Penalty: Warning ± revenue deduction. User-refund obligations imposed.

1.4 Prohibited Ad Placement & Interaction Design Violations

• Functional Area Pollution: Placing ads in areas where user interaction is inevitable (back button, confirm button, input field, settings options); placing ads that completely block functional operations, preventing normal app use. Penalty: Warning with correction deadline. Repeated violation: permanent ban.
• Banner Overcrowding: Displaying more than 2 banner ads on a single page; excessive banner placement obscuring main content or operational areas. Penalty: Warning. Correction deadline. Penalty escalation upon recurrence.
• Non-Closeable Interstitials: Interstitial ads without a close button, or close buttons that are visually undetectable or deliberately unreachable (e.g., rendered outside the viewport or at near-zero effective size). Penalty: Temporary ban until correction. Possibly permanent with no appeal.
• Short-Interval Interstitial Bombardment: Placing interstitial ads at intervals of less than 30 seconds between consecutive operations (excluding user actively clicking to skip). Penalty: Warning. Correction deadline. Multi-time offenders: account suspended.
• Function-Entry Mislabeled as Ad: Setting the only entry points for core functions to forced ad viewing; making actual function entries invisible unless ads are viewed. Penalty: Immediate account ban. Revenue confiscated. Non-negotiable.
• Interactive Ad Blocking: Intercepting user ad interaction events — blocking ads from recording impression and click events, preventing advertisers from obtaining valid feedback data through technical means. Penalty: Permanent account ban. Illegal revenue recovery. Legal action for damages.

2. IAP In-App Purchases: Protection Rules

IAP (In-App Purchase) constitutes virtual goods / digital service transactions between users and developers. To ensure transaction fairness, protect user rights, and maintain platform order, the following comprehensive protection rules are established:

2.1 Pricing Transparency

• All IAP items must accurately and clearly display the purchase price (inclusive of all taxes and fees) in local currency. No hidden fees or surcharge traps.
• Virtual currency or item packages must clearly display the per-unit price for easy comparison by users.
• Discounted items must clearly display the original price, discount rate, and post-discount price. False price anchoring (artificially inflating "original price") is prohibited.
• Price changes must be clearly announced to users in advance, effective only after the user has viewed the notice and commenced use thereafter.

2.2 Purchase Confirmation & Delivery

• Before each IAP order is submitted, a complete order summary must be presented: item name, quantity, total price (in local currency), payment method, and approximate payment time.
• After successful payment, the purchased virtual items/services must be delivered immediately (or within a stated reasonable period, not to exceed 1 hour under normal circumstances).
• If delivery fails (system error, network interruption), the order shall remain valid and the user must be able to re-receive the items upon re-login or through the "Restore Purchases" feature.
• A clear purchase history and consumption record must be provided within the app for user verification and financial reconciliation.

2.3 Refund Protection

• Users may request a refund through in-app channels or the App Store / Google Play refund system. We will process refund requests within the timeframes required by Apple and Google.
• For unsatisfied purchases, users may contact our support team within 14 days of purchase for refund assistance. We will evaluate all refund requests fairly.
• Previously purchased items remain valid during the refund processing period. If the refund is successful, the corresponding virtual items will be recalled from the user's account.
• We do not charge any refund processing fees. All refunds are processed for the full purchase amount.

2.4 Virtual Currency Management

• Virtual currency consumption rules must be transparent. Consumption records and balance inquiry features must be provided at all times.
• Virtual currency has no cash value, is non-transferable, and cannot be exchanged outside the application.
• Virtual currency validity periods (if applicable) must be clearly communicated to users in advance. Expiring balances must trigger system notifications.
• No hidden consumption mechanisms. Virtual currency may not be deducted without explicit user confirmation of each transaction's item and quantity.

2.5 Anti-IAP Fraud Rules

• Receipt Forgery / Falsification: Modifying IAP order receipts using technical means to simulate false payments and steal virtual items. Penalty: Permanent account ban. Fraudulent gains recovered. Legal action for fraud damages.
• Cross-Region Arbitrage: Using VPNs or GPS spoofing to access lower-priced regions for purchase and then consuming items in higher-priced regions. Penalty: Warning. Regional price difference recovered. Recidivists: permanent purchase capability restriction.
• Altered Device Information: Modifying device fingerprints (IMEI, MAC address, device ID, etc.) to simulate new devices, repeatedly claiming "first purchase" or "new user" discounts. Penalty: Permanent purchase restriction. Non-negotiable.
• Chargeback Fraud: Purchasing large amounts of virtual items, consuming or transferring them, and then maliciously initiating a payment chargeback through the bank or payment platform. Penalty: Permanent account ban. Gap amount recovered. Legal action for fraud.
• Grey-Market IAP Trading: Trading in-app virtual items or currencies between users through external platforms or offline channels. Penalty: Account suspended. Transaction items recalled. Permanent ban on final offense.
