3.1 Guest Account and Data Retention Rules / 游客账号与数据保留规则

用户无需注册账户即可通过“游客模式”体验本应用的基本功能。游客账户下的免费额度及比价数据与您当前使用的设备和应用安装状态相关联。
Users can experience the basic features of this App through "Guest Mode" without registering an account. Free quotas and price comparison data under a guest account are associated with your current device and app installation state.

风险提示 / Risk Warning: 在游客模式下，若您卸载本应用、清除应用数据或更换移动设备，可能会导致游客模式下的历史记录和免费额度丢失且无法找回。
In Guest Mode, if you uninstall the App, clear app data, or replace your mobile device, your Guest Mode history and free quota may be lost and cannot be recovered.

绑定建议 / Account Binding Recommendation: 为确保您的历史记录与付费权益在跨设备或卸载重装时不会丢失，建议您及时绑定并登录正式账号（如 Apple ID）。登录后，您在游客模式下的所有合法权益及数据将自动转存并合并至您的正式账户。
To ensure that your history and paid benefits are not lost across devices or upon reinstallation, we recommend that you bind and log in to an official account (such as Apple ID) in a timely manner. After logging in, all your lawful rights, benefits, and data from Guest Mode will be automatically transferred and merged into your official account.

4. Paid Services and Subscription Rules

• Some functions of the App are paid services, including but not limited to premium subscriptions and consumable quota packs.
• Specific prices, benefits, validity periods, and auto-renewal rules are subject to the display on the purchase page and the App Store.
• Auto-renewing subscriptions are processed by default under the Apple platform rules. You may cancel at any time via the following path: Device Settings > [Your Apple ID] > Subscriptions > Select TrueUnitX > Cancel Subscription. The cancellation will take effect at the end of the current billing cycle, and no refunds will be provided for fees already paid within the current cycle.
• Refund, revocation, and settlement rules for virtual services are subject to applicable laws and platform policies (e.g., Apple Media Services Terms and Conditions). If you believe you are eligible for a refund, you may submit an application via Apple's reportaproblem.apple.com.
• We reserve the right to adjust product forms and pricing based on operational conditions and will publicly announce or notify you in advance as required by law.

If you are a consumer located in the European Union or the European Economic Area, you have a 14-day right of withdrawal for digital content or services under the EU Consumer Rights Directive (2011/83/EU). However, please note: Once you unlock a digital service or content via in-app purchase, and we have begun providing that service/content (e.g., unlocking premium features, consuming AI recognition quotas), you will immediately lose your right of withdrawal, provided that we have obtained your explicit consent and acknowledgment of the loss of this right. Clear notice of this will be provided on the purchase page before the transaction is completed.

6. AI Output and Disclaimer

• AI recognition and price comparison results are affected by image quality, product label completeness, model capabilities, and network status, and may contain errors, delays, or omissions.
• Price information displayed in the App may be subject to lag. The actual transaction price, inventory status, promotional rules, and shipping fees are subject to real-time information on the checkout pages of third-party e-commerce platforms or physical stores. TrueUnitX assumes no legal liability for the product quality, inventory, shipping, after-sales service, and final transaction price of third-party platforms.

• You must exercise your own judgment and bear the risks and consequences of decisions made based on AI results.

This license is limited to fulfilling service functions, and we will not use your uploaded images for model training, advertising, or other unrelated purposes (see the Privacy Policy for details).
