Privacy Policy

The short version

CleanBG has no upload endpoint. When you remove a background, the AI model runs inside your browser on your own device. Your image, the mask and the result never leave your computer or phone. We cannot see, store or recover your images because they are never transmitted to us.

What happens when you use the tool

1. Model download. The first time you use CleanBG on a device, your browser downloads the neural network weights (about 100–220 MB) from our content delivery network. This is an ordinary static file download; the request contains no information about your images.
2. Local processing. Your image is decoded in a Web Worker in your browser, the model computes an alpha mask, and the transparent PNG is composed on a canvas — all in memory on your device.
3. Caching. The browser stores the model in its Cache Storage so later visits work offline. You can clear it at any time from your browser settings.

You can verify this yourself: open your browser's developer tools, watch the Network tab while processing an image, or disconnect from the internet after the model has loaded.

Data we do collect

• Server logs. Like every website, our hosting provider (Cloudflare) records standard request logs — IP address, user agent, requested page and time — for security and abuse prevention. These logs never contain image data.
• Analytics. If enabled, we use privacy-respecting, aggregate page analytics (page views, country, browser family). We do not track individual users across sites and we never log filenames, image dimensions or pixel data.
• Local storage. CleanBG stores a small amount of data in your browser (localStorage and Cache Storage) to remember your language, theme and which model configuration works on your device. This stays on your device.

Data we do not collect

We do not require accounts, do not ask for your name or email, do not store your images or results, and do not sell or share personal data with third parties.

Cookies

CleanBG uses a single functional cookie to remember your language preference. No advertising or tracking cookies are set by the tool. If ads are introduced in the future, this policy and the cookie notice will be updated first.

Children

CleanBG is a general-purpose utility and does not knowingly collect personal information from anyone, including children.

Changes

We may update this policy as the product evolves. The "last updated" date at the top reflects the latest revision.

Model credits

CleanBG is built on open models released under the MIT license. The weights are downloaded to your browser and remain under their original licenses.

• BEN2 (Background Erase Network 2) by PramaLLC — github.com/PramaLLC/BEN2. We serve a converted copy of the onnx-community/BEN2-ONNX export with fp32 compute for WebGPU compatibility.
• BiRefNet by Zheng Peng et al. — github.com/ZhengPeng7/BiRefNet, browser-ready 512px export studioludens/birefnet-lite-512.
• Transformers.js and ONNX Runtime Web run the models in the browser (Apache-2.0 / MIT).

HEIC photos

Safari can decode iPhone HEIC files natively. Other browsers load a local copy of heic-to / libheif (LGPL-3.0) only when you open a HEIC file. Conversion happens in your tab; the photo is not sent to us. Full notice and source links: Licenses.
