This privacy policy describes how I (the developer) collect, use, and share information when you use my mobile game Lucky Marbles (the “App”). I am committed to protecting your privacy and ensuring transparency about my data practices.
I do not collect personally identifiable information (such as your name, email address, or phone number) directly from you. However, the App may collect certain non‑personal data automatically through third‑party services integrated into the App.
a. Automatically Collected Information
When you use the App, third‑party services I use may collect certain information automatically, including:
Device information (e.g., device model, operating system version, unique device identifiers, advertising identifier [IDFA])
Usage data (e.g., gameplay sessions, interactions with the App)
Crash logs and performance data
The information collected is used for the following purposes:
To display relevant advertisements and measure ad performance
To analyze app usage and improve the user experience
To diagnose technical issues and fix crashes
To comply with legal obligations
I do not sell or rent your personal data. I may share the automatically collected data with third‑party service providers as necessary to operate the App, such as:
Advertising networks (to serve ads)
Analytics providers (to understand usage)
Legal authorities if required by law or to protect my rights
All third parties are contractually obligated to use the data only for the purposes specified and to maintain appropriate security measures.
Ad Tracking: You can reset or limit the use of your advertising identifier at any time through your device settings:
iOS: Settings → Privacy → Tracking (disable “Allow Apps to Request to Track”) or Settings → Privacy → Advertising (reset Advertising Identifier)
Opt‑out of Interest‑Based Ads: You can opt out of personalized ads via the network’s settings (e.g., Google’s Ads Settings at https://adssettings.google.com).
GDPR Rights (for EU/EEA users): You have the right to access, rectify, or delete your personal data. Since I collect only minimal non‑personal data, these requests can be directed to the third‑party services. For any inquiries, contact me at cbr4130@163.com.
I retain automatically collected data for as long as necessary to fulfill the purposes outlined in this policy, unless a longer retention period is required by law. Third‑party services may retain data according to their own retention policies.
The App is intended for a general audience and does not knowingly collect personal information from children under 13 years of age (or the applicable age in your jurisdiction). If you believe a child has provided personal information through the App, please contact me, and I will take steps to delete such information.
I take reasonable measures to protect the information I collect from unauthorized access, alteration, or destruction. However, no method of transmission over the internet or electronic storage is 100% secure.
I may update this privacy policy from time to time. I will notify you of any changes by posting the new policy on this page and updating the “Last Updated” date. I encourage you to review this page periodically for any changes.
