Privacy by design
Your files don’t leave your device.
Duck Tools has no upload API. Images, documents and text are processed by code running in your browser tab — with WebAssembly codecs and, for AI tools, models that run on your own hardware.
To be precise: your browser still downloads the pages, scripts and — for AI tools — model weights, and caches them. What we don’t do is receive your data. Read the details.
- Runs locallyEvery current tool processes your input inside your browser.
- No trackingNo analytics scripts, no tracking cookies, no ad networks.
- On-device AIOpen-source models download once, cache in your browser and run via WebGPU.
