Privacy Policy 
Murmur Ideas Limited operates the mobile application “介紹番 Noted with Fans” (the “App”). The App is provided as a free, ad-free application with optional in-app purchases available now or in the future. 
 
We are committed to protecting your privacy and personal data. This Privacy Policy explains how we collect, use, disclose, and safeguard information when you use the App, in line with applicable data protection laws and best practices. By downloading, installing, or using the App, you agree to the practices described herein. If you do not agree, please do not use the App. 
 
 
Information We Collect 
We collect minimal information necessary to provide and improve the App. All personal data is retained on your device and not transmitted to our servers unless explicitly provided by you: 
 
Personal Information (Voluntary): Email address or contact details submitted for customer support, feedback, or account-related inquiries. This is not automatically collected. 
 
Usage and Log Data: Automatically collected diagnostic information, including device type, Internet Protocol (IP) address, operating system version, app configuration, crash reports, usage timestamps, and interaction statistics. This helps diagnose errors and optimize performance. 
 
Camera and Photo Access: The App may request access to your camera or photo library only to capture or upload mahjong tile images for recognition. Images are transmitted securely to our servers for processing and are not shared with third parties. You may decline permissions, but some features may be unavailable. 

No Sensitive Data: We do not collect financial information, health data, government IDs, or other sensitive personal details. 

Survey Data: We may occasionally invite users to participate in optional, anonymous in-app surveys or feedback forms requesting non-identifiable information (e.g., age range, years playing mahjong, general comments). Participation is voluntary, and responses are used in aggregate only to improve user engagement. 

How We Use Your Information 
We use collected information solely to: 

• Provide, maintain, and improve App functionality (e.g., Mahjong scoring features). 

• Analyse usage patterns for bug fixes and performance enhancements. 

• Respond to your support requests or feedback. 

• Facilitate optional in-app purchases processed securely by third-party platforms (Apple/Google). 

​Where applicable privacy laws require a legal basis for processing, we rely on the following: 

• Legitimate interests – to operate, maintain, and improve the App and its performance. 

• Your consent – when you voluntarily submit personal data (e.g., through feedback or support requests). 

• Contractual necessity – to facilitate in-app purchases or respond to your service inquiries. 

We ensure any processing remains proportionate and necessary for the stated purposes. 

We do not sell, rent, or share your personal data with advertisers or other third parties for marketing purposes. 

 
Third-Party Services 
The App integrates limited third-party services for essential functionality: 
Google Play Services 
Google Analytics for Firebase (for Android) 
or  
Apple App Store Analytics (for Apple) 

These providers may collect device identifiers as described in their policies. We do not control or assume responsibility for their practices. Moreover, these providers may process data on servers located outside Hong Kong. Where personal data is transferred outside Hong Kong, we have no control to ensure that the recipient provides a standard of protection comparable to that under Hong Kong’s Personal Data (Privacy) Ordinance. 
 
Data Retention and Security 
Personal information is retained only as long as necessary to fulfill the purposes outlined above or to meet legal requirements. Upon request or app uninstallation, data is deleted from our systems where applicable. 
 
We implement commercially reasonable administrative, technical, and physical security measures (such as encryption and access controls) to protect your data. Where limited diagnostic or analytical data is stored by third-party processors, it is maintained in secure, access-controlled environments with encryption in transit and at rest. We regularly review our data handling practices to ensure compliance with current privacy standards. However, no method of internet transmission or electronic storage is 100% secure, and we cannot guarantee absolute security. 
 
Children’s Privacy 
The App is not intended for children under 13 years of age. We do not knowingly collect personally identifiable information from children under 13. If we discover such data has been collected, we will delete it immediately. Parents or guardians concerned about their child’s data should contact us promptly. 

We may disclose information if required to do so by law or in the goodfaith belief that such action is necessary to: 

• Comply with a legal obligation or government request; 

• Protect and defend our rights or property; or 

• Prevent or investigate potential wrongdoing in connection with the App. 

​ 
Your Rights 
You have the right to: 

• Request access to, correction of, or deletion of your personal data. 

• Withdraw your consent to the processing of your data. 

• Request information about our data policies and practices relating to personal data. 

To exercise these rights or lodge a complaint, please make your request in writing to our contact address listed below, specifying the details of your access or correction request. We may require reasonable verification of your identity before processing. 

 
Links to Other Sites 
The App may contain links to external websites or services. We are not responsible for their content, privacy practices, or data policies. Review them independently before use. 

Changes to This Privacy Policy 
We may update this policy periodically to reflect changes in our practices or legal requirements. The updated version will be posted here with a revised effective date. Continued use of the App after changes constitutes acceptance.
