Wynn ("we", "us", or "our") operates mobile applications (collectively, the "Service"). This page informs you of our policies regarding the collection, use, and disclosure of information when you use our Service.
Most app data is stored locally on your device. Depending on the app you use, this may include game progress, scores, preferences, reading records, registered books, reading sessions, notes, collected quotes, room customization settings, and reward state.
DadokBook does not require account registration or remote sync. Reading records and profile settings are stored on the device. When you use book search or ISBN barcode lookup, the search query or ISBN may be sent to a third-party book search API to provide book results. Book cover images may be downloaded from result URLs and cached locally for display.
DadokBook uses the camera only when you choose ISBN barcode scanning. Camera frames are used for barcode recognition and are not stored by us.
DadokBook v1 includes Firebase Analytics to measure aggregate app flow, feature usage, funnel drop-off, failure states, and privacy or permission limitation states. DadokBook-defined analytics events do not include book title, author, ISBN, memo text, collected quote text, internal app data IDs, contact information, or precise location.
Our Service may use third-party services that collect information used to identify you. These third-party services include:
Our apps may display advertisements through Google AdMob. On iOS 14.5 and later, you will be asked for permission before tracking occurs (App Tracking Transparency). You may opt out at any time through your device settings. If you do not allow tracking, core app features remain available.
Our Service is not directed to anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.
We do not operate account servers for these apps. Data stored locally remains on your device unless you choose to use features that contact third-party services, such as advertisements, analytics, or DadokBook book search. We use reasonable care to limit data use to the purposes described in this policy.
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
