Private cleanup does not need image uploads.
GenClean separates image processing from account checks so generated image pixels stay local.
What stays local
The browser handles image decoding, detection, cleanup, preview, and PNG/ZIP export. GenClean does not need to upload your image to a remote rendering queue just to repair a small visible corner mark.
This matters for creators working with unreleased campaigns, client concepts, product mockups, or personal projects. Keeping image pixels local reduces exposure and makes the cleanup flow faster.
What reaches the server
Only usage counters, hashed IP/day keys, email/license entitlement checks, and payment metadata are needed for free limits and Pro access.
Why usage checks still exist
The free plan needs basic abuse protection, and the Pro plan needs a way to verify purchases. Those checks can happen without uploading the image file. A serverless function can authorize the action, while the browser performs the actual image repair.
What private processing looks like in practice
When you choose an image, the browser reads the file, draws it to a canvas, estimates the visible Gemini mark region, and creates the repaired preview locally. The download is generated from that local canvas. This is different from services that upload the original image to a server, process it remotely, and send back a new file.
For creators, that difference is practical. You can test drafts, client concepts, unreleased products, and campaign ideas without adding a remote image processor to the workflow. You still need an internet connection for the page, payment checks, and free-limit checks, but the pixels do not need to be sent to those endpoints.
Security boundaries
Local processing is not the same as a legal guarantee or enterprise security certification. It is a product architecture choice that reduces the amount of sensitive data GenClean needs to handle. For highly confidential work, review your own client agreements and security requirements before using any browser-based tool.
What local processing does not mean
Local processing does not change image rights or platform obligations. If a client, publisher, or marketplace requires AI disclosure, you still need to follow that rule. GenClean is for visible presentation cleanup on permitted images, not for hiding provenance or bypassing detection.
