🔒 Privacy & Security by Design
Dumkera is built for the security-conscious professional. By using WebAssembly (WASM) and ONNX Runtime, we move the processing from our servers to your machine.
Traditional online tools require you to upload your sensitive PDFs, private photos, and videos to their cloud.
On Dumkera, your files never leave your device. Open your browser's Developer Tools (Network Tab) and verify it for yourself.
We are GDPR compliant, CCPA compliant, and enterprise-ready.
