1. Developer and Contact
SmartLED is provided by Soosu Studio. For privacy questions, data requests, or support, please contact us at contactus@soosu.studio.
2. Information SmartLED Handles
SmartLED lets you create, save, play, and share LED sign presets. The app does not require account registration and does not ask for your name, phone number, contacts, precise location, camera, microphone, photos, or calendar access.
- LED presets saved on your device: message text, colors, text color ranges, background color, glow color, text size, scroll speed, direction, blink settings, mirror mode, text style, LED dot size, LED dot shape, row count, sort order, and update time.
- Shared LED links: when you create a share link or QR code, SmartLED uploads the LED preset settings needed to open that shared sign. This includes the message text and visual settings encoded in the share payload, a generated share ID, a custom app link, version information, and creation time.
- App usage and diagnostic information: SmartLED uses Firebase Analytics, which may collect app interaction, device, app version, operating system, and diagnostic information to help us understand reliability and improve the app.
- Website preferences: the SmartLED web page may store a language preference in your browser's local storage.
3. How We Collect Information
- Information is created when you use the app's editor, save LED presets, or generate share links and QR codes.
- Shared LED link data is sent to Firebase Cloud Firestore only when you choose to create a share link.
- Firebase Analytics collects app usage and diagnostic information through the Firebase SDK.
- If Android backup is enabled on your device, Android or your device provider may back up app data according to your device settings.
4. How We Use Information
- To save and display your LED sign presets on your device.
- To generate QR codes and shareable links that let another device open the same SmartLED sign settings.
- To maintain, debug, secure, and improve SmartLED and its web sharing page.
- To respond to support or privacy inquiries that you send to us.
5. Sharing and Third-Party Services
We do not sell your personal information. SmartLED uses Google Firebase services, including Firebase Analytics and Cloud Firestore. Data processed through Firebase is handled by Google according to Google's applicable Firebase and privacy terms.
When you share a QR code, image, or URL through another app, that sharing action is handled by the app or service you choose. Please review that service's privacy practices before sharing.
6. Public Nature of Shared Links
SmartLED share links are designed to be opened by anyone who has the link. Do not include private, sensitive, confidential, or illegal content in an LED message that you share. If you share a link with someone else, they may further copy or distribute it.
7. Retention and Deletion
- LED presets saved in the app remain on your device until you edit, delete, uninstall, or reset the app, subject to Android backup behavior on your device.
- Shared link records may remain in Firebase Cloud Firestore so the links can continue to work. To request deletion of a shared link record, contact us with the share URL.
- Firebase Analytics retention follows the settings and retention controls available in Firebase and Google Analytics for Firebase.
- Support emails are retained only as long as reasonably necessary to respond to your request, maintain records, or meet legal obligations.
8. Security
We use reasonable technical and organizational measures to protect information handled by SmartLED. Shared link data is stored in Firebase Cloud Firestore with security rules that validate the expected share format. However, no method of transmission or storage is completely secure.
9. Children's Privacy
SmartLED is not directed to children under the age required by applicable law to use online services without parental consent. We do not knowingly collect personal information from children. If you believe a child has provided personal information through SmartLED, please contact us.
10. International Processing
Information processed through Firebase or other service providers may be stored or processed in countries outside your country of residence. We take steps intended to use service providers with appropriate privacy and security commitments.
11. Changes to This Policy
We may update this Privacy Policy from time to time. When we make changes, we will update the date below and publish the revised policy on this page.
