LED-Grid Privacy Policy
Effective Date: August 3, 2026
1. Introduction
LED-Grid ("the App") is an LED display construction assistant tool developed by the LED-Grid team ("we", "us"). This policy explains how the App handles your information. Our principle is minimalism: the App does not collect, transmit, or sell any personal data.
2. Information We Collect
The App does not collect any personally identifiable information (such as name, email, phone, or location). Specifically:
- Photos: Photos you take or select from your gallery are processed locally on your device only (corner detection, perspective correction, overlay annotation). Photos are never uploaded to any server.
- Configuration data: Cabinet parameters, wiring schemes, and annotation records you create are stored only as local files on your device. You may export them as .ledg files and decide who to share them with.
- Logs: Operation logs are stored locally only (Documents/LED-Grid/logs) for your own review and are never uploaded automatically.
3. Permissions
- Camera: Used only to photograph LED display screens for annotation, triggered only when you actively use it.
- Gallery / Media (READ_MEDIA_IMAGES): Used only to select existing photos for annotation.
All permissions are requested only when you actively use the feature and are never accessed otherwise.
4. Third-Party Services
- In-App Purchases (App Store / Google Play Billing): The App offers a one-time paid unlock of Pro features. All transactions are handled entirely by Apple App Store (iOS) and Google Play (Android). We cannot access your payment information, card numbers, or related store account credentials. We only receive a "purchased / not purchased" status to enable features.
- External links: The "About" page provides a link to the project website, opened by your system browser. No information is collected within the App.
5. Data Storage & Deletion
All your data is stored locally on your device. To delete: uninstalling the App removes all app data (photos and exported files saved in the system gallery or public directories should be deleted by you).
6. Data Sharing
We do not share, sell, or disclose any user data to third parties (App Store / Google Play billing transaction data is handled by Apple / Google under their respective privacy policies).
7. Children's Privacy
The App is intended for LED display engineering professionals and is not directed at children. We do not collect personal information from anyone, including children.
8. Changes to This Policy
If this policy changes, we will update this page and revise the "Effective Date". Material changes will be communicated via in-app release notes.
