Every file stays in your browser sandbox. Nothing is transmitted to our servers — ever.
When you select a PDF or image, it is read into your browser's local memory. The file is never transmitted to our servers or hosted in external storage.
Calculations, format conversions, and rendering are executed via client-side JavaScript and HTML5 canvas layers running in your local thread.
Outputs are converted into local data buffers and downloaded directly to your machine. No file logs, records, or cached buffers exist on our backend.
