TXBoard Privacy Policy
Last updated: May 7, 2026
Effective date: May 7, 2026
We attach great importance to the protection of your personal information and privacy. We follow the principles of legality and compliance, minimum necessity, openness and transparency, security, and reliability when protecting your data security and privacy. We have prepared this Privacy Policy (the "Policy") to help you understand how we collect, use, transmit, store, and protect your personal information, and how you may exercise your related rights.
This Privacy Policy applies to the products and services, and their extended functions, provided by Mianchi Tianxin Technology Co., Ltd. ("we", "us", or "our") under "甜心大屏" (English name: TXBoard), including mobile applications, web services, and new forms of products or services that may appear as technology develops. By agreeing to this Privacy Policy, you acknowledge that you understand the basic and non-basic functions provided by TXBoard, and agree that we may process personal information necessary to ensure the normal operation of the basic functions. For information that is not necessary but relates to extended functions, we will separately inform you and obtain the corresponding authorization according to the specific scenario.
1. Types of Personal Information We Collect
1.1 Basic Necessary Information for Using TXBoard
In accordance with laws and regulations, we do not collect personal information unrelated to providing services to you or unrelated to your use of TXBoard. We follow the principles of legality, legitimacy, necessity, and good faith, and only collect personal information that is necessary or relevant to implementing product functions.
The current version of TXBoard does not provide user registration, mobile phone login, WeChat login, Apple login, or any other user account function. Therefore, we do not collect your mobile phone number, verification code, account password, third-party account identifier, nickname, avatar, or other account profile information based on a login or account system. If a future version adds user login or account functions, we will update this Policy before the function is launched and, where necessary, obtain your separate authorization and consent.
Local settings and display content: TXBoard is mainly used to display time, weather, calendars, anniversaries, countdowns, background images, and similar information. The city, weather preferences, display layout, theme, background, anniversaries, countdowns, and other settings that you configure in the app are usually stored locally on your device and are used to restore and display your dashboard page.
Weather and location-related information: When you use weather functions, we may query weather data based on a city you manually select or location-related information that you authorize us to use. If you deny location permission, you may still use some weather functions by manually selecting a city. The specific available functions are subject to the actual functions provided in the app.
Operation and security information: To provide and improve the services you need, we may collect relevant operation and security log information generated when you use the services, including your IP address, device model, operating system version, app version, language, network status, and necessary access logs. This information is used for version checks, troubleshooting, service security, compatibility optimization, and product stability improvement.
App version information: TXBoard may request the current version status from our version management service in order to provide upgrade prompts, mandatory upgrade prompts, or compatibility notices. This process may involve necessary information such as the app name, app version, build number, device system type, and network request logs.
1.2 Information Collected by Third Parties
When you use TXBoard-related functions, we may receive information from third-party partners that is returned to us in accordance with your authorization or their service rules, and we may integrate and use such information with information we collect ourselves, provided that this complies with laws, regulations, and this Policy.
The current version does not provide third-party account login or account linking functions. If a future version adds WeChat, Apple, or other third-party login capabilities, we will update this Policy before the function is launched and explain the specific scope of information processed.
We do not sell or rent any of your personal information for third-party marketing purposes. We will only share relevant information in accordance with law when we have obtained your prior consent or authorization, when sharing with affiliates as permitted by law, when required by laws, regulations, or competent authorities, or when necessary to protect the legitimate rights and interests of the platform, users, and relevant parties.
For personal information directly processed by third-party SDKs or technical services, the relevant partners will process such information in accordance with their own privacy policies. The specific providers, types of information processed, usage scenarios, and relevant links are shown in the table below.

Description of Other Third-Party Services That May Be Used:
The following description applies to scenarios where we enable relevant capabilities on corresponding platforms, device environments, or function versions. If a relevant function is not enabled in the version you are currently using, the corresponding personal information will not be processed based on that function.
The current version of TXBoard does not provide user login. Therefore, it does not process your account identity information based on SMS verification codes, WeChat login, Apple login, or account linking. If a future version adds relevant functions, we will update this Policy based on the actual processing and fulfill the corresponding notification obligations.
1. If you use functions such as weather, location, system reminders, background image selection, or ad display, the system or third-party services may request permissions such as location, notifications, photos, network access, and advertising identifiers according to function needs. You may manage relevant permissions through system settings. Turning off some permissions may affect the use of corresponding functions, but will not affect other basic display functions.
2. How We Use the Collected Information
2.1 Maintaining a Complete and Secure TXBoard Service Environment
We will use, store, and process your information (including personal information) within the scope necessary to achieve service purposes, including providing dashboard display, weather queries, calendar and reminder functions, background management, version checks, ad display, product experience optimization, troubleshooting, system and service security, and fulfilling our legal obligations.
We will take reasonable precautions to protect your personal information from unauthorized access, disclosure, use, alteration, damage, or loss. For example, we adopt encryption, protection, and monitoring measures at the technical level, and improve employees' awareness of security and privacy protection through systems and training at the management level. However, please understand that no security measure can be absolutely risk-free.
The above processing is based on our compliance with applicable laws, performance of service agreements with you, fraud and risk prevention, improvement of service quality, and legitimate needs to maintain the secure and stable operation of the platform.
3. Disclosure of Collected Information
3.1 Permission and Authorization
We may share your personal information with other parties in accordance with your instructions at the time of consent after obtaining your prior consent. The current version of TXBoard does not provide public content posting or social interaction functions.
3.2 Security Incident Handling
The internet environment is not 100% secure, and we will make every effort to ensure the security of any personal information you send to us. In the unfortunate event of a personal information security incident, we will notify you in a timely manner in accordance with laws and regulations of the basic situation and possible impact of the incident, the measures we have taken or will take, suggestions for you to independently prevent and reduce risks, and remedial measures for you. We will notify you of the incident by email, letter, phone call, push notification, or one or more other methods. Where it is difficult to notify personal information subjects one by one, we will publish an announcement in a reasonable and effective manner. At the same time, we will actively report the handling of personal information security incidents in accordance with regulatory requirements.
3.3 Exceptions to Information Disclosure
In general, we will not transfer or publicly disclose your personal information to any company, organization, or individual. However, to the extent required or permitted by law, or where reasonably necessary, TX Screen may disclose your information (including personal information) to courts, law enforcement authorities, government authorities, or authorized third parties, and may do so without obtaining your authorization or consent: (1) to comply with legal obligations; (2) to comply with legal procedures and respond to claims brought against TXBoard; (3) to respond to verified relevant requests in connection with criminal investigations, allegations, suspected illegal activities, or any other activities that may expose us, you, or any other user to legal liability; (4) to enforce or manage our terms of service or other agreements with users; (5) to protect the rights, property, or personal safety of TXBoard, its employees, users, or the public; (6) where necessary to respond to public health emergencies, or in emergency situations to protect the life, health, and property safety of natural persons; or to process your personal information within a reasonable scope for public interest activities such as news reporting and public opinion supervision. Where appropriate, we will attempt to notify users, unless notice is prohibited by legal procedure, court orders we receive, or applicable law. If we did not send notice due to the above legal requirements, and we later determine in good faith that such notice is no longer legally prohibited, we will attempt to notify users of the relevant request afterwards. To comply with our legal obligations, protect the vital interests of you or others, or serve our or third parties' legitimate interests in maintaining TXBoard service security, preventing harm or crime, exercising or defending legal rights, or preventing damage, such disclosures may be necessary.
4. User Rights
To protect the security of your personal information, we strive to take various reasonable physical, electronic, and administrative security measures to protect your personal information from leakage, damage, or loss. If you have any questions about TXBoard's processing of your personal information, or if you wish to exercise your rights under law, such as access, correction, deletion, withdrawal of consent, or account cancellation for future versions, please contact us. You may contact us by sending an email to service@tianxin.tech. Please note that we may ask you to verify your identity before taking further action on your request. The current version does not provide user account functions, so it does not provide account profile editing, third-party account unlinking, or account cancellation entry points. You may modify or delete local settings in the app or system settings, or withdraw permissions such as location, notifications, photos, or advertising identifiers through system permission management. You have the right to request that we correct your inaccurate or incomplete personal information. For information stored locally on your device, you may also manage it through app settings, system settings, clearing app data, or uninstalling the app. In certain jurisdictions, applicable law may give you the right to request a copy of the personal information we hold about you. You may also have the right to request a copy of the personal information we hold about you in a structured, commonly used, machine-readable format, and/or request that we transmit such information to another service provider where technically feasible.
5. Data Retention, Transfer, and Deletion
We will retain your personal information for the period necessary to achieve the service purpose according to the business scenario. If laws or regulations impose mandatory retention requirements, we will extend the retention period in accordance with law. The main display settings in the current version are usually stored locally on your device, and you may delete them through app settings, system settings, clearing app data, or uninstalling the app.
For third-party services such as the Tencent Youlianghui / GDT Advertising SDK, Google AdMob / Google Mobile Ads SDK, weather services, and system platform capabilities, the data processed during service provision may be transmitted, stored, or processed according to their service networks and privacy policies. Where cross-border provision of personal information is involved, we will take necessary protective measures in accordance with applicable legal requirements.
The current version does not provide user account functions, so there is no account cancellation process. If you no longer wish to use TXBoard, you may delete local app data or uninstall the app. Please note that, as necessary to comply with laws and regulations, handle disputes, identify fraud, and ensure platform security, we may still retain some necessary logs within the scope permitted by law. Due to backup mechanisms, some copies of information may not be completely deleted from backup systems immediately.
If TXBoard undergoes a merger, acquisition, restructuring, asset transfer, bankruptcy, or similar transaction, your personal information may be transferred as part of the transaction. In such cases, we will take reasonable measures within the scope required by law and notify you of such changes where appropriate.
6. Account and Login Functions
The current version of TXBoard does not provide user login, registration, account profiles, third-party account binding, or account cancellation functions. If a future version adds user login or account functions, we will update this Policy accordingly, explain the rules for collecting, using, storing, canceling, and deleting account information, and provide corresponding user rights entry points in accordance with law.
7. How This Privacy Policy Is Updated
To provide you with better services and continuously improve our products as our business develops, this Policy may be updated from time to time. However, without your explicit consent, we will not materially reduce the lawful rights you are entitled to under this Policy. After the Policy is updated, we will explain the update through website announcements, page prompts, or other appropriate methods. Please also check the latest version in a timely manner.
8. Applicable Law

Where there are no relevant legal provisions, general international business practices and/or industry practices shall be referenced.
