Privacy Policy

LumiLab

LumiLab maintains its privacy policy directly on the official website. We take your privacy extremely seriously. Designed as a local-first tool, it fundamentally guarantees the safety of your photo library data.

Effective Date: 2026-08-15

1. Introduction

  • We take your privacy extremely seriously. LumiLab is designed as a local-first application. You have absolute control over your photo library, image files, and any associated data.
  • The core philosophy of this app is to utilize on-device artificial intelligence for all data processing, fundamentally eliminating any risk of data leakage.

2. Information We Collect

  • By default, we do not collect, store, transmit, or sell any of your personal data or image files to developer-controlled servers.
  • You do not need to register for an account to use the full core features of this application.
  • No developer server uploads: whether it is the images you scan, generated quality scores, AI feature vectors, or your cleanup logs, everything is strictly kept locally on your device.

3. Core Principle: 100% Local Processing

  • AI computations are entirely local: face detection and recognition, duplicate and similar-photo clustering, aesthetic scoring, and eye-closure analysis all run on your device's CPU or GPU with on-device inference.
  • Data isolation: image feature data generated during analysis only exists within the local database, never leaving your device. Storage uses SQLite plus a local vector store.
  • AI models are downloaded to a folder you control (customizable in Settings) and are verified before use; they are never bundled into the app or uploaded anywhere.

4. Permissions Usage

  • Photo/File Access: to read and analyze your images, the app requests permission to access the specific folders you choose as photo libraries on first use.
  • Security Commitment: LumiLab only reads images within the scope you explicitly authorize and will never access unauthorized files or directories. File movement operations (such as moving rejects to a trash folder) are protected by system-level sandboxing.

5. Third-Party Services & Analytics

  • We strictly do not integrate any third-party ad networks or behavioral tracking plugins (such as Google Analytics, Facebook Pixel, etc.).
  • Your usage habits, culling preferences, and personal characteristics will not be packaged and sent to any data brokers.

6. Data Retention and Deletion

  • Delete handling: when you confirm cleanup, rejected photos are handled per your chosen delete method — moved to an in-library trash folder, the system Trash, or permanently removed. The default is a recoverable destination, never silent permanent deletion.
  • App data cleanup: if you decide to uninstall LumiLab, all locally generated index and feature database caches associated with it are removed through the system's uninstallation process. Original photo files are never modified or deleted by uninstalling.

7. Changes to the Privacy Policy

  • As the app evolves or legal requirements change, we may update this privacy policy appropriately. If changes occur, we will publish the updates on this page and update the Effective Date at the top. We encourage you to review this page periodically.
