LUMISCENE
Privacy policy.
Effective: November 7, 2026 · Updated: November 7, 2026
How LUMISCENE handles photos, Bluetooth connections and your privacy choices.
1. About this policy
This Privacy Policy applies to LUMISCENE, provided by Shenzhen Grovemind Technology Co., Ltd. (深圳市智林星瀚科技有限公司, “we”, “us” or “our”). LUMISCENE connects to a physical LED photocard case over Bluetooth to adjust lighting effects, colors, brightness and speed. You can also select or take a photo for the virtual photocard displayed in the app, or scan the QR code on the back of a physical case to identify and connect to that device.
LUMISCENE is free to use, with no account registration, login, in-app purchases or subscriptions. This policy explains local processing in the app and information handled when you choose to contact us or visit this policy webpage.
2. Information and purposes
Photos and camera frames
Photos you choose or take are cropped, previewed and stored locally on your phone to display a photocard in the app. Photos are not sent to us, uploaded to a server or transmitted to the physical case. Camera frames used for QR scanning are processed on your phone, are not saved as video and are not uploaded. The app does not automatically read your entire photo library, perform facial recognition or create biometric profiles.
Case information and lighting settings
The app locally processes information in a QR code used to identify the case, as well as Bluetooth device names, identifiers and connection status, to identify and connect to the case you select. Lighting effects, colors, brightness and speed settings are stored on your phone, and control commands are sent to the case over Bluetooth. This information is not uploaded to our servers or used for advertising or cross-app tracking.
Email you choose to send
If you email us, we receive your email address, message and any attachments you choose to send. We use this information only to respond, provide support and handle privacy requests. Please send only what is needed to resolve your request, without passwords or unnecessary personal information.
3. Device permissions
- Bluetooth / nearby devices: Used to discover, connect to and control the case you select. If permission is denied or Bluetooth is turned off, the app cannot connect to the case or send lighting commands.
- Camera: Used when you open the scanning or photo-taking feature, to read a case QR code or take a photocard photo for the app. Denying access makes those features unavailable.
- Photos / system image picker: Used only when you choose to import an image, to access the images you select or authorize for the in-app photocard. You can limit photo access or use the system’s individual-image picker where available.
Permission names and authorization options may differ by operating system and version. You can manage or revoke these permissions in your phone’s system settings at any time. Revoking a permission does not automatically delete previously saved photos or settings; see the deletion section below. We do not use the microphone, obtain or store your physical location, or track location in the background.
5. Storage, retention and security
Local app data: Photo copies, saved cases and lighting settings remain in the app’s storage on your phone until you remove the content, clear app data or delete the app. We do not have a server copy and cannot remotely view, recover or erase this local data for you.
Email records: We retain correspondence only for as long as needed to handle an enquiry, support matter or privacy request, and delete it when the matter is complete and further retention is no longer necessary. Records required by law are kept only as required. You may also request deletion using the email address below.
We rely on the phone’s application access controls to protect local data and restrict access to support correspondence. This policy webpage uses HTTPS. Please protect your phone and use a screen lock; no storage or transmission method can be guaranteed completely secure. System backups, device migration and synchronization of your original photo library depend on your device settings and those services, rather than a cloud feature provided by us.
6. Your choices and deletion
- Remove photocard images: Delete imported photocard images within the app. This removes the app’s copy, not the original in your phone’s photo library.
- Remove a case: Delete a saved case and its associated settings in the app. This does not factory-reset the physical case.
- Clear all local data: On Android, clear LUMISCENE’s app storage in system settings or delete the app. On iOS, use “Delete App” rather than “Offload App”, which keeps documents and data. Manage system backups, original photos and copies on other devices separately.
- Withdraw permissions: Turn off camera, photo or Bluetooth permissions in your phone’s settings. The corresponding features will be affected.
LUMISCENE has no user accounts, so no account-deletion request is needed. For personal information you have sent to us by email, you may request access, correction or deletion, or withdraw relevant consent. Email kimsung92@gmail.com with your request. We will verify identity only to the extent necessary and handle the request under applicable law. If a legal obligation prevents deletion of certain records, we will explain why.
7. Children and guardians
LUMISCENE is for a general audience, including children using it under the guidance of a parent or guardian.
Children should use the app with the guidance of a parent or guardian, who should help manage camera, photo and Bluetooth permissions. The app does not ask children for their name, contact details or an account, and contains no advertising or in-app purchases. Photos, QR scanning and lighting settings follow the local processing described above.
A parent or guardian should contact us on a child’s behalf and avoid sending unnecessary personal information about the child. If you believe a child has sent us personal information without appropriate permission, contact us below so we can investigate and delete it as required by applicable law. If future features require children’s personal information to be transmitted to us, we will first update the relevant notices and obtain parental consent where required by applicable law.
8. Changes to this policy
We will publish updates on this page and revise the updated date. Before material changes to our information practices take effect, we will provide notice in the app or through another appropriate method and seek consent again when required.
