  1. Certain features require an internet connection, system permissions, an Apple Account, or support from third-party services. You may choose whether to grant non-essential permissions. Refusing a permission may prevent the corresponding feature from functioning but will not affect features that do not require that permission.
  2. We may adjust the services, interface, features, rules, and scope of support in response to business development, technology upgrades, user experience considerations, applicable laws and regulations, or regulatory requirements. If an adjustment materially affects your rights and interests, we will notify you in an appropriate manner as required by law.

2. Account and Device Security

4. Special Notice Regarding AI Product Authenticity Analysis

  1. The AI product authenticity feature analyzes the images and related information you submit using artificial intelligence image analysis and comparisons with publicly available data. It provides only supplementary, probabilistic information for reference.
  2. AI output may be affected by image clarity, shooting angle, lighting, product-version differences, the quality of public data, model capabilities, and the completeness of your input. Results may contain errors, omissions, bias, or inconsistencies.
  3. An AI authenticity result does not constitute official certification by a brand or rights holder, professional authentication, quality inspection, valuation, legal advice, or a transaction guarantee, and it cannot replace a conclusion issued by a qualified institution.
  4. You should not rely solely on an AI authenticity result when making a purchase, sale, payment, rights-enforcement, or other material decision. For high-value goods or disputed transactions, seek further verification from the brand, an authorized channel, or a qualified professional institution.
  5. You must ensure that you have the right to upload the relevant images and information. Do not upload sensitive personal information unrelated to the authenticity check, another person’s private information, or unlawful content.

5. Scanning, Recognition, Image Enhancement, and Third-Party Information

  1. QR-code and barcode content may be created by third parties. We do not control its authenticity, security, or legality. Before opening a URL from scan results, placing a call, sending a text message or email, adding a contact, joining a Wi-Fi network, or visiting a social platform, verify the information yourself and remain alert to security risks.
  2. Text recognition, code scanning, product search, nutrition information, and rating results may be inaccurate due to image quality, algorithmic limitations, delayed data updates, or errors in third-party data. You should verify results against the original source material.
  3. Product, nutrition, pricing, link, and other information supplied by Open Food Facts, search engines, e-commerce platforms, and other third parties is the responsibility of the relevant third party. Third-party services may be governed by their own terms and privacy policies.
  4. Image enhancement, restoration, or saved-image results may vary depending on the device, image format, operating-system version, and technical limitations. Back up original files before overwriting or deleting them.

6. Intellectual Property

  1. Intellectual property rights in the App’s software, interface, designs, text, graphics, icons, trademarks, programs, algorithms, and related content belong to us or the relevant rights holders. Without authorization, you may not copy, modify, distribute, rent, sell, reverse engineer, or otherwise use such materials for commercial purposes.
  2. You retain the applicable rights in uploaded and created content that you lawfully own. To provide the feature you select, you grant us a license to process, transmit, and cache that content to the extent and for the period necessary to provide the feature. This license does not transfer ownership of your content to us.
  3. You must ensure that the images, logos, text, contact information, and other content you upload are obtained and used lawfully. You are legally responsible for any infringement of third-party rights caused by your content.
  4. Rights in third-party trademarks, product images, data, and other content belong to their respective rights holders. Their appearance in the App does not indicate authorization, sponsorship, or an official partnership between us and the relevant brand unless expressly stated otherwise.

7. Privacy and Data Protection

We value your personal information and privacy. Depending on the features you use, the App may process images from your camera or photo library, contact information you select, Sign in with Apple information, scan and creation records, authenticity-check materials, and device and diagnostic information. For the purposes, methods, scope, retention periods, third-party sharing, and your rights regarding such processing, please refer to the Privacy Policy.

8. Changes, Suspension, and Termination of Services

  1. The services may be temporarily interrupted, restricted, or changed due to system maintenance, technology upgrades, changes to third-party services, network failures, device compatibility, force majeure, or changes in laws or policies. We will take reasonably practicable steps to minimize the impact.
  2. If you violate this Agreement, compromise service security, or infringe the lawful rights and interests of others, we may lawfully restrict, suspend, or terminate some or all services provided to you.
  3. When the services terminate, your right to use them also ends. We will process relevant data in accordance with applicable law and the Privacy Policy, except where retention is required by law or necessary to resolve a dispute.

9. Disclaimers and Limitations of Liability

  1. We will take measures required by law and within our reasonable commercial and technical capabilities to maintain the security and stability of the services. However, we do not guarantee that the services will always be uninterrupted or error-free, meet every specific purpose, or be compatible with every device, system, or third-party service.
  2. Where recognition fails, is delayed, or produces inaccurate results due to network fluctuations, device performance, system permissions, image quality, errors in the code itself, or abnormalities in third-party data or services, we will bear liability in proportion to our actual fault to the extent permitted by law.
  3. When accessing third-party websites, applications, products, or services through scan results, you should independently assess their security and authenticity. The relevant third party is responsible for independently provided content and services, except where damage is caused by our willful misconduct or gross negligence.
  4. The exclusions and limitations of liability in this Agreement do not apply to personal injury caused by our willful misconduct or gross negligence, property damage caused by our willful misconduct or gross negligence, or any other liability that may not be excluded or limited by law.
