This Privacy Policy explains how the operator of the mobile application Scanner (hereinafter referred to as the “App”) collects, uses, stores, discloses and protects the personal information of all users who access and use our services. By downloading, installing and using the App, you acknowledge that you have read, understood and agreed to the practices described in this Privacy Policy. If you do not agree with any part of this Policy, please stop using the App immediately. This Privacy Policy is an integral part of the Scanner End User Terms of Service and forms a binding legal agreement between you and the App operator. 1. Scope of Application This Policy applies to all users of the App, including all free and premium service scenarios. It covers all personal information collected and processed through your use of the App’s scanning, recognition, editing, conversion and cloud storage functions. 2. Information We Collect We only collect information that is necessary to provide our services, in accordance with the minimum necessity principle. We do not collect any unnecessary personal data. 2.1 Authorized Device Permissions and Data Camera Access: Used exclusively for capturing photos of documents, certificates and files to complete scanning functions. Camera access will not be invoked in the background, and no images will be uploaded automatically without your consent. Photo Gallery Access: Used to import local images for scanning and editing, and to save processed files and exported documents to your device. Local Storage Access: Used to cache task data, save processed files and ensure normal operation of the App. All local files are stored only on your device by default. 2.2 Automatically Collected Information We may collect anonymous device information, including device model, system version and anonymized device identifiers, to optimize device compatibility, fix crashes and improve user experience. Such data cannot be used to identify any individual user. We may also collect anonymous application logs and operation records for fault diagnosis and service optimization. 2.3 Voluntarily Provided Account Information If you register an account to use cloud synchronization and premium services, you will voluntarily provide account-related information for identity verification, cloud data storage and membership right binding. 2.4 Information We Do Not Collect The App will not actively collect your location data, contacts, microphone data, calendar data, health data, SMS records, payment information or other sensitive personal information irrelevant to core scanning functions. 3. How We Use Your Information All collected information is used only for the following purposes: a. To provide, maintain and optimize core services including document scanning, OCR recognition, PDF conversion, file editing and document export; b. To fix application failures, resolve crashes and optimize functional compatibility with different devices; c. To verify user identity, provide membership services and process service feedback; d. To respond to user consultation, complaint and service requests; e. To comply with applicable laws and platform requirements. Your scanned documents, certificates and private files are stored locally on your device by default. No document data will be automatically uploaded to the cloud without your explicit authorization. 4. Data Storage and Security Local user files are controlled and managed by you. Cloud data will only be stored after you actively enable the cloud synchronization function. Operation logs and fault data are retained for a limited period and will be automatically cleared upon expiration. Cloud account data will be retained during the valid period of your account and completely cleared after account cancellation. We adopt data encryption transmission, data desensitization and access isolation technologies to protect user data. We have established internal management rules to prevent unauthorized access, disclosure or misuse of user information. 5. Third-Party Service and Data Sharing We will not sell, trade or rent your personal information to any third parties. The App may access compliant third-party technical services for intelligent recognition and function optimization. Any data shared with third parties will be limited to the minimum non-sensitive information required for service implementation, fully disclosed in this Policy and authorized by you explicitly. All third-party service providers are required to comply with data protection laws and privacy standards. They are not permitted to use your data for unauthorized purposes. 6. App Tracking Transparency This App does not enable user tracking by default. We will not obtain advertising identifiers or track user behavior across applications and websites without your explicit permission. If tracking permission is required in the future, we will obtain your consent through official system pop-up windows. You may accept or refuse tracking authorization, and refusal will not affect the use of basic App functions. You may adjust tracking permissions at any time in your device system settings. 7. Account Deletion and User Rights You may cancel and delete your account independently through the in-app entry located in 【Settings - Account Security】. After account deletion, all account registration information, cloud documents, membership data and related personal information will be completely cleared and cannot be recovered. Please back up important data before cancellation. If you use the App as a guest without registration, all data is stored locally only and will be completely cleared after you uninstall the App. You have the right to access, correct, delete your personal data and withdraw authorization at any time through device settings or in-app functions. 8. Minor Privacy Protection This App is intended for users aged 13 and above. Users aged between 13 and 18 shall use the App under the supervision and consent of their legal guardians. We do not knowingly collect personal information from children under 13. If you are a guardian and find that your child has provided us with personal information without consent, please contact us promptly to delete relevant data. 9.
