In-Browser Privacy Architecture

CalmSnug runs 100% inside your browser using HTML5 Canvas 2D, WebGL, and JSZip. When you drop, paste, or select images, they are decoded into your device’s local memory sandbox. No photos, files, or pixels are ever transferred over the network to any remote server or third-party cloud.

Frequently Asked Questions

Are my images uploaded to any server when using CalmSnug?

No. CalmSnug runs 100% inside your browser using WebGL and HTML5 Canvas API. No photos or graphics are ever sent to any remote server.

What image formats can I export?

You can export in PNG (lossless transparent), JPG (optimized photo format), or WebP (modern lightweight web standard).

Is there an image size limit?

Since rendering occurs on your device, images up to 8K resolution (8192×8192) can be processed comfortably depending on your GPU/RAM.
