Welcome to Lumina Prompt. Your privacy is our top priority. This Privacy Policy is designed to provide full transparency regarding how our application operates, how we handle technical data, and our commitment to not collecting your personal information in the public version of this application.
1. Privacy Commitment & Data Identity
Lumina Prompt is built on the principle of Privacy by Design. We guarantee the following for the public version of the application you use:
No Registration Required: This application does not require account creation. We do not request, collect, or store your name, email address, phone number, or any other identification data.
No Identity Tracking: We do not track users' real-world identities. Your interactions within the application are entirely anonymous.
2. Technical & Analytical Data (Non-Personal)
While we do not collect personal data, we utilize third-party analytical tools (Google Analytics for Firebase) to collect anonymous technical data to ensure optimal application performance across various devices:
Device Information: Hardware model, operating system version (Android), screen resolution, and system language.
Diagnostic Data: Crash logs or technical bug reports to help developers implement fixes in future updates.
Interaction Statistics: Information on which features are most frequently used to help us improve the overall User Experience (UX).
3. Third-Party Services & Advertising
To keep this service free for all users, we partner with third-party providers who adhere to strict privacy policies:
Google AdMob (Advertising): We display limited advertisements. Google may use your device's unique Advertising ID (AD_ID) to deliver relevant ads. You have full control to reset or disable this ID through your Android system settings (Settings > Google > Ads).
Google Firebase: We utilize Cloud Firebase infrastructure to distribute our prompt and image database in real-time. All data transmissions between the server and your device are secured with high-level SSL/HTTPS encryption.
4. Device Permissions & Network
Storage & Media Access (READ_EXTERNAL_STORAGE & WRITE_EXTERNAL_STORAGE)
These permissions are required to support our image caching system and to enable the image-saving features within the application.
Image Caching & Performance: The application temporarily stores image assets in your device's local memory to optimize performance. When you re-open a previously accessed prompt, the application retrieves the cached data instead of downloading it again from the server. This is designed for:
Data Conservation: Significantly reduce your internet data consumption.
Access Speed: Enhance responsiveness and provide a smoother, faster navigation experience.
Save Images to Device: These permissions allow you to download and save images generated or provided by the application directly to your device’s local storage or gallery, so you can access them offline or share them outside the application.
Note: We respect your privacy. While the app requires access to storage to save your requested images and manage cache, we do not access, read, collect, or share your existing personal photos, documents, or other media files stored on your device. The application only interacts with the specific images you choose to save and its own internal technical assets.
Internet & Network Access (INTERNET & ACCESS_NETWORK_STATE) These permissions are required to establish a secure connection with our servers. They enable the application to retrieve the prompt database in real-time and verify active network connectivity prior to initiating data synchronization processes.
Vibration Control (VIBRATE) This permission allows the application to provide subtle haptic feedback (vibrations) when interacting with specific user interface components or upon the completion of loading tasks, thereby improving the overall user experience.
Prevent Device Sleep (WAKE_LOCK) This permission ensures application stability during critical background operations, such as cache synchronization. It prevents the device from entering a low-power sleep state mid-process, minimizing the risk of data corruption or unexpected interruptions.
5. Local Storage & Caching System
To enhance access speed and save your cellular data usage, we implement a local storage system:
Image Caching: Loaded prompt images will be temporarily stored in the application's internal memory so they do not need to be redownloaded upon reopening.
Local Favorites: The list of prompts you mark as "Favorites" is stored exclusively within your device's local storage. This data is never sent to our servers and will remain intact as long as the application is installed on your device.
Data Clearance: You can clear all cache data and favorites at any time through the application's settings menu or via the Clear Data feature in your Android system settings.
6. Data Security & Encryption
The security of technical information flowing through our application is protected using industry-standard encryption. We ensure that our back-end infrastructure is regularly updated to prevent unauthorized access and to maintain the integrity of the content delivered to you.
7. Children's Privacy (COPPA Compliance)
Lumina Prompt is a safe application for all audiences. We do not knowingly collect any data from children under the age of 13. Given that this application features no login system, there is no risk of intentional data collection from children by our system.
8. Policy Changes
We reserve the right to update this Privacy Policy at any time in conjunction with the development of new application features. Any changes will be informed through updates on this page by revising the "Last Updated" date.
