This Privacy Policy is the Global Version and applies to all users who use the products or services of this App. For legal requirements specific to certain countries or regions, we provide a "Regional Addendum / Supplemental Terms" (if any). Where the Regional Addendum is inconsistent with this Privacy Policy, the Regional Addendum shall prevail; for matters not covered therein, this Privacy Policy and Applicable Law shall govern.

Your applicable service region under the Terms of Service will primarily be determined by the country/region you select at registration. To ensure the correct assignment of the service region, we may reference device- or network-related information (for example, IP address, network environment data, and device locale settings) to assist in verification. If we detect any inconsistency with the registered region, we will send you a notice via in-app messaging or to the email address/phone number linked to your account, and we may ask you to confirm the information through our support team.

Personal Information / Personal Data: information recorded by electronic or other means that can identify a specific natural person on its own or in combination with other information, or that reflects the activities of a specific natural person, including without limitation name, date of birth, government-issued identification number, biometric identifiers, address, contact details, communications records and content, account credentials, financial information, credit/creditworthiness information, location data, accommodation/lodging information, health and physiological information, and transaction information.

Sensitive Personal Information: information that, if leaked, unlawfully provided, or misused, may endanger personal or property safety, or is likely to result in reputational harm, mental/physical health damage, or discriminatory treatment, including without limitation government-issued identification numbers, biometric identifiers, bank account information, communications records and content, financial information, credit/creditworthiness information, precise location data, accommodation/lodging information, health and physiological information, transaction information, as well as personal information of children.

Processing of Personal Information: collection, storage, use, processing, transmission, provision, public disclosure, deletion, and other operations.

Deletion / Erasure of Personal Information: removing personal information from routine/operational business systems so that it cannot be retrieved or accessed.

Anonymization: irreversible technical processing that renders the data subject unidentifiable or unrelatable, and the result cannot be restored.

De-identification / Pseudonymization: technical processing that prevents identification or association with a data subject without the use of additional information.

Data Subject: the natural person who is identified by or associated with the personal information.

Personal Information Controller / Processor: an organization or individual that determines the purposes and means of processing personal information is the Controller; a third party that performs processing activities under the Controller's written instructions is a Processor.

Device Information: includes device identifiers, application information (crash logs, notification toggle status, installed app list, and other app-related information), device and system parameters (device type/model, operating system and hardware information), network environment information (IP address, Wi-Fi information, cell tower/base station information, and other network-related information), and network identifiers (e.g., BSSID); subject to the actual data collected by the product.

Children: natural persons who have not reached the minimum age required under the laws of their location for the processing of personal information in connection with online services; the age varies by jurisdiction—for example, in the EU/EEA it is set by Member States between 13–16 years; in the UK and the United States it is under 13; in Mainland China and the Republic of Korea it is under 14; in India it is under 18. Where local law sets a higher or stricter standard, that standard applies.

1. Auto-start and Background Reception: To ensure that the App can continue receiving broadcast messages related to client installation package downloads while closed or running in the background, the App may use auto-start capabilities and, at certain intervals, be awakened via system broadcasts to auto-start or perform associated launches to deliver necessary features and services.

2. Network Change Listening and Update Experience: To avoid unnecessary data usage and provide an improved update experience, the App listens for network state changes and, together with its auto-start capability, promptly alerts you to install once an installation package has finished downloading.

3. Viewing Terms Prior to Consent: Before you accept the User Agreement and this Privacy Policy, if you click to view the relevant terms, we will open them in the system browser to avoid any third-party SDK collecting your personal information at this stage.

4. WeChat Sharing Integration: The App integrates WeChat sharing. After completing a share, returning to the App to display the share status may require relaunching the App. On devices where the App is installed, links you share may deep-link to the App for quick viewing.

5. Auto-Start Permission; Push and Payments: The App integrates JPush for notifications. To help you quickly view notification content, we may wake and open the App via notifications to display the relevant content. The App integrates WeChat Pay; after completing a payment, returning to the App to display the payment status may require relaunching the App. To ensure you receive platform messages (e.g., messages/comments) in a timely manner, we may request your authorization for auto-start to avoid the App being terminated prematurely in the background by the system. If you decline authorization, these features will not be available, but basic functions remain unaffected. We will follow regional and platform (device/OS) policies and rules regarding background behavior and permission prompts.

We collect and use your personal information for the following purposes and in accordance with the rules described below when providing our products/services:

1) Information Necessary for Core Features: To deliver core features and services, certain information is required; refusal to provide such information may prevent normal use of core features.

2) Optional Information for Additional Features: For additional/optional features, you may choose whether to grant permissions; refusal will affect only that feature or its effectiveness and will not affect the use of basic functions.

Location-Related Content/Services

With your authorization, we may use geolocation information related to the services (e.g., precise location, WLAN access points, Bluetooth and base stations, sensor information) to provide more tailored content or services. Precise location is Sensitive Personal Information; if you decline authorization, location accuracy may be affected, but other features will not be. Where authorization is not granted, we may display content/services based on city/district inferred from network information (e.g., IP). Optional features are disabled by default unless you enable them.

Device Sensors

During your use of the App, we may use direction/gravitation/gyroscope sensors to help detect genuine user activity; when you use capture/shooting features, we may use the accelerometer to determine the shooting angle.

Clipboard

When you copy/paste during use (e.g., SMS verification codes, phone numbers, device SN), we may request clipboard access and locally read the necessary text. Such information is processed on your device only, is not persistently stored, and is not used for other purposes.

Specific Feature Scenarios We Provide

1. Cookies

Cookies and similar device identifier technologies are commonly used on the Internet. When you use our services, we may send one or more cookies or anonymous identifiers to your device (collectively, "Cookies") to collect, identify, and store information about your visits and use of the products. We will not use Cookies for any purpose other than those described in this Privacy Policy. We primarily use Cookies to ensure the secure and efficient operation of the products and services, including confirming the security status of your account and transactions, troubleshooting crashes and latency issues, and helping you avoid re-entering the same form inputs or search queries.

2. Web Beacons and Pixel Tags

In addition to Cookies, we also use other similar technologies on our website, such as web beacons and pixel tags. A web beacon is typically a transparent image embedded in a website or email. Pixel tags in emails help us determine whether an email has been opened. If you do not wish for your activity to be tracked in this manner, you may unsubscribe from our mailing list at any time.

1. Sharing

We do not share your personal information with companies, organizations, or individuals other than the App's service providers, except in the following cases:

1.1 Sharing with Your Explicit Consent: We will share your personal information with other parties after obtaining your explicit consent.

1.2 Sharing Under Legal Circumstances: We may share your personal information externally as required by laws and regulations, for dispute resolution, or in response to lawful requests from administrative or judicial authorities.

1.3 Sharing with Affiliates: To provide services to you based on associated accounts, your personal information may be shared with our affiliates. We will share only the personal information necessary for the services (for example, we may share necessary account information to enable you to use affiliate products or services through your App account). If we share your sensitive personal information or an affiliate changes the purposes or methods of processing, we will seek your authorization/consent again.

1.4 Sharing with Authorized Partners: For the purposes stated in this Privacy Policy, certain services may be jointly provided by us and authorized partners. We may share some of your personal information with partners to deliver better customer service and user experience (e.g., arranging partners to provide services). We will share personal information only for lawful, legitimate, necessary, specific, and explicit purposes, and only the information necessary to provide the services. Our partners are not permitted to use the shared personal information for unrelated purposes.

2. Transfer

We do not transfer your personal information to any company, organization, or individual, except in the following cases:

2.1 Transfer with Your Explicit Consent: After obtaining your explicit consent, we may transfer your personal information to other parties.

2.2 Merger, Acquisition, or Bankruptcy: In the event of a merger, acquisition, or bankruptcy liquidation involving personal information transfer, we will require the new entity holding your personal information to continue to be bound by this Privacy Policy; if the new entity cannot meet this requirement, we will require it to obtain your authorization/consent again.

3. Public Disclosure

We may publicly disclose your personal information in the following situations:

3.1 After obtaining your explicit consent;

3.2 Legal Disclosure: Where disclosure is required by law, legal process, litigation, or mandatory requests from government authorities.

1. We use industry-standard security safeguards to protect the personal information you provide and to prevent unauthorized access, disclosure, use, alteration, damage, or loss. We will take all reasonable and practicable measures to protect your personal information. For example, data exchanged between your browser and our servers (such as credit card information) is protected by SSL (Secure Socket Layer) encryption (i.e., the HTTPS protocol); we use encryption technologies to enhance the security of personal information; we adopt trusted protection mechanisms to prevent malicious attacks; we deploy access control mechanisms to ensure that only authorized personnel can access personal information; and we provide security and privacy protection training to strengthen employees' awareness of the importance of protecting personal information.

2. We maintain an advanced, data-centric security management system that covers the full data lifecycle and enhances system security across multiple dimensions, including organizational structure, policy design, personnel management, and product/technical controls.

3. We will take reasonable and practicable measures to ensure that we do not collect irrelevant personal information. We will retain your personal information only for the period necessary to fulfill the purposes described in this Policy, unless an extension is required or permitted by law.

4. The Internet is not an absolutely secure environment. We strongly recommend that you do not send personal information via communication channels that are not recommended by the App. You may use our services to connect and share with others. When you create communications, transactions, or shares through our services, you may independently choose the parties with whom you communicate, transact, or share—who may then view related information such as your transaction content, contact details, communications, or shared content.

You can access and manage your information as described below, and we will respond to your requests when required by applicable laws and regulations:

1. Access Your Personal Information

You have the right to access your personal information, except as otherwise provided by laws and regulations. You may access it as follows:

1.1 Profile — To access or edit your date of birth, occupation, interests, mobile phone number, or other profile details, log in to your account and go to "Me" → "Settings."

1.2 Authorizations — Log in, tap the "Settings" icon in the upper right, then "Avatar" → "Settings," where you can disable or enable authorization options.

2. Rectify or Supplement Your Personal Information

If you discover inaccuracies in the personal information we process about you, you have the right to request rectification or supplementation. You may submit such requests using the methods described under "1. Access Your Personal Information."

3. Delete Your Personal Information

You may delete certain personal information via the methods described under "1. Access Your Personal Information."

4. Change the Scope of Your Consent

Each business function requires certain basic personal information to be completed (see Section I of this Privacy Policy). Beyond that, for additional collection and use of personal information, you may contact the App's customer service to grant or withdraw your consent.

5. Restricting Automated Decision-Making

In certain business functions, we may make decisions solely through non-human automated decision-making mechanisms, including information systems and algorithms. If such decisions significantly affect your lawful rights and interests, you may contact customer service.

6. Our Responses to Your Requests

To protect security, you may need to provide a written request or otherwise verify your identity. We may ask you to complete identity verification before processing your request.

7. Account Closure

We will retain your account data for 180 days. If you no longer wish to use our products, you may submit an account-closure request via "Me → Settings → Account Closure."

1. Applicable Age Thresholds

• EU/EEA: You may use the Services only if you are at least 16 years old. We do not provide the Services to individuals under 16, nor do we knowingly collect their personal information.
• Other Countries/Regions: The minimum age to use the Services is 13. We do not provide the Services to individuals under 13, nor do we knowingly collect their personal information.
• Higher Local Standards Prevail: If the laws of your location set a higher or stricter minimum age or require parental/guardian consent, that higher/stricter standard applies (e.g., India: under 18; Republic of Korea: under 14; Mainland China: special protections for children under 14).

2. Age Verification and Access Controls

To comply with legal obligations and protect minors, we may collect date of birth at registration or at necessary stages for age verification. If verification shows you do not meet the applicable age requirement, we will refuse registration or restrict/suspend the Services. If re-checks are triggered due to network location, relocation, or inconsistent information, we may ask you to provide additional information via customer support; until verification is complete, we may limit or pause relevant features.

3. Processing and Protection of Minors' Data

Without providing the Services to "Children" (EU/EEA: under 16; non-EU: under 13; Mainland China: under 14), for minors who meet the minimum use age but are under 18 (e.g., EU/EEA: 16–17; non-EU: 13–17; Mainland China: 14–17), we will:

1. Data Minimization and Purpose Limitation: Process personal information only to the extent necessary to provide/maintain the Services, apply reasonable retention periods, and implement security safeguards.
2. Profiling and Tracking Limits: Do not conduct profile-based targeted advertising for minors, and by default restrict/disable unnecessary cross-site tracking and precise location (stricter limits apply in EU/UK and similar jurisdictions).
3. Parental/Guardian Consent (where required by local law): Where "consent" is the lawful basis and guardian consent is required, we will process only after obtaining and verifying such consent; without consent, we will not process.
4. Rights and Remedies: Guardians may exercise rights (access, rectification, deletion, withdrawal of consent) via the published channels; upon verifying that an account belongs to a child below the minimum age, we will disable the account and delete the information.

5. Contact Us

If you are a parent or legal guardian and believe a minor who does not meet the applicable age threshold has provided personal information to us or used the Services, please contact us at buildmost03@yekalon.com. Upon verification, we will, to the extent permitted by applicable law, disable the account, delete the related personal information, and provide feedback within the statutory period.

Personal information collected and generated during our operations within the People's Republic of China (PRC) is stored within China. Personal information may be stored or transmitted across borders only under the following circumstances: where explicitly required by law; where we have obtained your explicit authorization; or where you engage in cross-border activities via the Internet (e.g., live streaming/posting). When cross-border transfers occur, we will provide appropriate protection as described in this Policy.

For personal data transferred from the EEA/UK/Switzerland, we will use recognized transfer mechanisms (e.g., EU Standard Contractual Clauses (SCCs), the UK IDTA or its Addendum, or other applicable frameworks), together with necessary technical and organizational measures (such as encryption and access controls).

To provide better products, services, and technologies, we may update this Policy due to new services or process changes and will publish all changes on this page. For material changes, we will provide more prominent notice (including but not limited to in-product badges or pop-up reminders, or emails under specific services detailing the changes). We will not diminish your rights under this Policy without your explicit consent.

Material changes include, without limitation:

• Significant changes to the service model (purposes of processing, types of personal information processed, methods of use, etc.);
• Major changes in ownership structure or organizational structure (e.g., business adjustments, bankruptcy, or mergers and acquisitions);
• Changes to the primary recipients of personal information for sharing, transfer, or public disclosure;
• Significant changes to your rights in personal information processing or how those rights may be exercised;
• Changes to the department responsible for personal information security, contact information, or complaint channels;
• Personal information security impact assessments indicating high risk.

For ease of reading, this Policy may be provided in multiple languages. In the event of inconsistency or ambiguity among different language versions, the version most aligned with the applicable laws of your location and marked on the publication page as the "Effective Version" shall prevail. Where mandatory local laws apply, such laws and any Regional Addendum take precedence.

Where required by applicable law, we will provide the contact details of our Data Protection Officer (DPO) and/or our designated representative in the EEA/UK. You may also lodge a complaint with, or seek redress from, the data protection supervisory authority having jurisdiction in your location. Relevant information will be displayed in "How to Contact Us" below or in the applicable Regional Addendum.
