Privacy policy

BlindWMLocal (watermark.shrinklocal.com) is a static, browser-only tool in the ShrinkLocal family. There is no server-side image processing API.

We do not receive your images

Watermark embedding, extraction, and detect analysis run entirely in your web browser using JavaScript. Image bytes are not transmitted to our servers for processing — there is no backend endpoint that accepts photos.

Offline use

After the page and scripts load, you can disconnect from the network and still embed, extract, or screen images. Choosing a file and running the tool does not require an active connection. This is by design: all computation happens on your device.

What we may log

Like any website, our host may record standard access logs (URL, IP, user agent) for security and operations. These logs do not contain your image content.

Session storage

After you embed a watermark, we may store extract parameters (length, level) in your browser’s sessionStorage to help the Extract page — this never leaves your device.

Third parties

We do not use third-party analytics on this tool by default. The watermark library is bundled and served from this domain.
