1. Absolute Zero Network Upload Policy

CleanPix is engineered strictly as a Local-First Firefox Add-on. All image processing—including background removal, background replacement, and image resizing—executes entirely on your local device inside your browser using WebAssembly and native Web APIs.

No Third-Party APIs: CleanPix does NOT use remove.bg, Cloudinary, Adobe, Canva, OpenAI, Google, or any remote image processing services.
No Remote Inference: Machine learning models run locally via ONNX Runtime WebAssembly directly on your CPU/GPU.
No Image Uploads: Your photos, background images, and resized outputs NEVER leave your computer.


1. Data Retention & 6-Hour Purge Policy

CleanPix prioritizes zero-persistent storage. Images are processed exclusively in volatile browser RAM memory (Blob, Canvas, ImageBitmap) and released immediately upon reset or closing.

No Permanent Image Database: CleanPix does not store your images in IndexedDB, LocalStorage, Firefox Sync, or remote databases.
Fail-Safe 6-Hour Data Deletion: In the event that any temporary browser storage or preferences are created during processing, CleanPix automatically purges all records older than 6 hours via browser startup checks and background alarms.
Automatic Memory Disposal: All created Object URLs are tracked and revoked with URL.revokeObjectURL().


1. Zero Telemetry & Zero Analytics

We respect your right to absolute privacy. CleanPix contains:

NO Google Analytics, Facebook Pixel, or tracking scripts
NO user behavior monitoring or session recording
NO IP address, location, or telemetry collection
NO advertising SDKs or fingerprinting scripts


1. Firefox Permissions Explanation

CleanPix requests only the absolute minimal permissions required to function locally:

downloads: Enables 1-click direct download of your processed images to your local Downloads folder.
storage: Enables local configuration preferences and temporary 6-hour cleanup state management.
alarms: Triggers periodic fail-safe checks to guarantee the 6-hour data deletion policy.


1. Contact & Open Source Verification

Because CleanPix is bundled locally inside your browser extension directory, you can inspect the full source code, Content Security Policy, and network logs at any time to verify that zero network connections are made.
