Hong Kong Yizhong Software Technology Co., Limited (香港翼衆軟件科技有限公司, “we”, “us”, or “the Company”) values your privacy. This Privacy Policy explains how we access, use, store, and protect your information through our applications.

1. Information we access

After you grant clear authorization, we may access the following through the Google Ads API:

• Basic Google Account information, such as account name and email address;
• Google Ads customer account data that you authorize;
• Campaign, ad group, ad, and keyword data;
• Advertising delivery statistics and reporting data;
• Other Google Ads data required to provide the application’s features.

We request only the permissions necessary to provide specific features.

2. How we use information

We use the information above to:

• Connect to and manage the Google Ads accounts you authorize;
• Create, edit, pause, or view campaigns, ad groups, ads, and keywords;
• Generate advertising performance reports and data analysis;
• Provide customer support, troubleshooting, and security maintenance;
• Improve application features and service stability.

We do not sell Google user data, and we do not use it for advertising targeting or credit assessment unrelated to the application’s core features.

3. Information sharing

We do not sell or rent your personal information.

Where necessary to provide the service, we may share limited information with:

• Cloud server, database, and backup service providers;
• Authentication, logging, and security service providers;
• Regulators or law-enforcement authorities where disclosure is required by law.

Service providers may process information only on our instructions and must comply with confidentiality and security obligations.

4. Storage and retention

We retain relevant information only for as long as needed to provide the service. After you revoke authorization, delete your account, or request deletion, we will delete or anonymize the relevant information within a reasonable period, except where retention is required by law.

Sensitive credentials, such as OAuth refresh tokens, are protected with encryption and access controls.

5. Data security

We use reasonable technical and organizational safeguards to protect your information, including encryption in transit, access controls, logging and monitoring, and secure backups. However, no internet transmission or electronic storage method can be guaranteed to be completely secure.

6. Google API data use

Our access to and use of Google user data complies with the Google API Services User Data Policy, including its Limited Use requirements.

We do not sell Google user data, use it for remarketing, or use it for purposes unrelated to the application’s core features.

You can revoke the application’s authorization from the third-party app access page in your Google Account.

7. Your rights

You may:

• Access, correct, or delete your personal information;
• Revoke your Google Account authorization;
• Ask us to stop processing relevant information;

Depending on the application and features you use, we may process the following categories of information:

Our public website may use essential cookies, local storage, or similar technologies to remember language preferences, keep pages secure, and understand basic technical performance.
