The App is the official smart assistant for POSTEK barcode printers and label printers. It is designed to support account registration, device connection, printer status monitoring, troubleshooting guidance, tutorials, and technical support.

2. Information We Collect

We collect information only as needed to provide and improve the App. Depending on the features you use, we may collect the following categories of information:

2.1 Account Information

When you register for or log in to a POSTEK account, we may collect:

• Your email address
• A system-generated user ID, account ID, or other account identifier
• Account status, registration time, login status, and other information needed to manage your account

We use your email address to send verification codes required for account registration, login, account deletion verification, or account security. We do not send marketing emails, promotional emails, or emails unrelated to verification codes unless you separately provide your explicit consent.

Account registration and smart assistant services in the App are provided free of charge to users.

2.2 Printer and Device Information

To provide device connection, status monitoring, troubleshooting, and technical support, we may collect or process:

• POSTEK printer model, device identifier, and connection status
• Printer status, error codes, fault messages, and printing parameter information
• Information related to print speed, darkness, media, consumables, or troubleshooting
• Records related to App-printer connection, pairing, communication, or print tasks
• Fault logs, diagnostic logs, or support logs that you choose to submit or agree to share

2.3 Usage Data and Diagnostic Data

When you use the App, we may automatically collect certain usage and diagnostic data, such as:

• Device model, operating system version, and App version
• IP address and network connection information
• App crash logs, performance data, and error logs
• Feature usage, operation records, or service request records

2.4 Permission-Related Information

When you use certain features, the App may request access to device permissions such as Bluetooth, NFC, camera, photos, files, or notifications. We access these permissions only when required by the feature and after you authorize the relevant permission.

If related data is processed only locally on your device and is not uploaded to our servers or our service providers' servers, we do not treat that data as collected by us.

2.5 Customer Support Information

When you contact us or submit a technical support request, we may collect contact information you provide, problem descriptions, screenshots, logs, support materials, and information related to your communication with technical support.

3. How We Use Your Information and Legal Bases

We may use the information we collect for the following purposes:

• To create and manage your POSTEK account
• To send registration, login, account deletion, or account security verification codes to your email address
• To authenticate users and protect account security
• To provide, maintain, and improve App features
• To connect and manage POSTEK printers
• To monitor printer status and provide troubleshooting guidance for common issues
• To provide image, video, or step-by-step tutorial guidance
• To handle technical support requests and analyze faults
• To maintain system security and prevent fraud, abuse, or unauthorized access
• To analyze and improve App stability, performance, and service quality
• To comply with applicable laws and regulations

For users in the European Economic Area, the United Kingdom, or other regions that require a legal basis for processing, we rely on the following legal bases where applicable:

• Contract necessity: to create and manage your account, provide the App, connect devices, deliver smart assistant features, and provide requested support.
• Legitimate interests: to maintain security, prevent abuse, troubleshoot errors, improve reliability, and protect our rights and users, provided those interests are not overridden by your rights.
• Consent: to access device permissions such as Bluetooth, NFC, camera, photos, files, or notifications, and to process optional logs or support materials that you choose to submit.
• Legal obligation: to comply with applicable laws, regulatory requests, or legal process.

We do not use your email address for advertising or marketing emails. We do not sell your personal information.

4. No Tracking, Advertising, or Sale of Personal Information

We do not use the personal information collected through the App to track you across other companies' apps or websites for advertising or data broker purposes.

We do not sell your personal information. We do not share your personal information for cross-context behavioral advertising or targeted advertising.

If App Store privacy labels apply, the data types declared in App Store Connect should match the information described in this Privacy Policy, including email address, user ID, device identifier, IP address, diagnostics, usage data, and support logs where applicable. If the App does not track users, the App Store privacy label should remain consistent with "Data Not Used to Track You."

5. How We Share Your Information

We may share information only when necessary in the following situations:

5.1 Service Providers, Third-Party SDKs, and Cloud Services

We may use third-party service providers to help us provide cloud services, account systems, verification email delivery, data storage, troubleshooting, technical support, or service maintenance. These service providers may process your information only as necessary to provide services to us and must provide appropriate protection for your information.

The current version may involve the following service providers, third-party SDKs, or cloud services. The final list should be updated based on the released build, backend configuration, and actually enabled features:

• Supabase / POSTEK Supabase backend, including https://backend.postek.com.cn: account authentication, verification codes, user profiles, database, real-time messages, chat/service records, and related backend functionality. Possible data may include email address, user ID, account status, printer serial number or device identifier, chat records, support records, IP address, and network request information.
• Supabase project ncqpiryntqxrsmefqjge.supabase.co: if this project is still used in the released version, it may process AVA/printer tokens, messages, user submissions, or feedback. Possible data may include printer serial number, user ID, message content, feedback content, and contact information.
• Email verification service provider: delivery of registration, login, password reset, account deletion, and account security verification codes. Possible data may include email address, email delivery logs, security logs, IP address, and timestamps. The specific provider name should be confirmed and inserted before publication.
• Volcengine Ark (ark.cn-beijing.volces.com): if the released version enables AVA smart assistant chat responses, this service may be used to generate troubleshooting or usage guidance responses. Possible data may include your chat input, chat context, language preference, and printer model, fault description, or diagnostic information that you choose to provide.
• Alibaba Cloud OSS (oss-cn-hongkong.aliyuncs.com): if you submit support logs, screenshots, images, videos, or other issue materials, this service may be used for file storage and transmission. Possible data may include files, logs, images/videos, file paths, and upload time.
• Apple and iOS system services: operating system permissions, device-level privacy controls, notifications, App Store distribution, and platform diagnostics where enabled by the user or the system. Whether such data is collected by us depends on whether the data is received by us or our service providers.
• Local feature plugins or SDKs: the App may use plugins related to Bluetooth, NFC, scanning, photos/files, network information, device information, and local notifications, such as flutter_blue_plus, flutter_nfc_kit, mobile_scanner, image_picker, file_picker, gal, network_info_plus, device_info_plus, and flutter_local_notifications. These plugins are mainly used to implement local features. If related data is processed only on your device and is not uploaded, we do not treat that data as collected by us.

If we add or replace third-party SDKs or service providers that collect personal information, we will update this Privacy Policy or our third-party SDK/service provider list accordingly. SDKs that are not enabled in the released version or not included in the final app package will not be listed as active third-party services.

5.2 Affiliates

We may share information with POSTEK ELECTRONICS CO., LTD. or other POSTEK affiliates where reasonably necessary for product engineering support, technical support, after-sales service, fault analysis, customer request handling, internal service management, or legal compliance. We will require affiliates to protect the information in accordance with this Privacy Policy or equivalent protection standards.

5.3 Legal Requirements and Business Changes

We may disclose information where required by applicable laws, regulations, courts, government authorities, or regulatory agencies. If we are involved in a merger, restructuring, asset transfer, or similar transaction, your information may be transferred as part of that transaction. We will provide notice where required by applicable law.

6. Data Retention

We retain personal information only for as long as necessary to fulfill the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law.

• Account information is generally retained while your account remains active.
• Verification codes expire after a short period. Email delivery and security logs related to verification may be retained for up to 90 days unless a longer period is required for security, dispute resolution, or legal compliance.
• Fault logs, diagnostic logs, crash logs, and support records are generally retained for up to 24 months after the relevant issue is resolved, unless a longer period is needed for security, product improvement, legal compliance, or dispute resolution.
• Backup copies may remain for a limited backup cycle after deletion before being overwritten or securely deleted.
• When you delete your account or request deletion of personal information, we will delete or de-identify the relevant information unless retention is required or permitted by law.

7. Account Deletion and Your Rights

If you create an account in the App, you can delete your account from inside the App through the account or account information page and the Delete Account function. The App may ask you to verify your email address or enter a verification code before deletion to protect account security.

Depending on applicable law, you may have the right to access, correct, delete, restrict, object to processing, withdraw consent, request portability, appeal a denied privacy request, or contact us about your privacy choices.
