At SudexHub PDF Tools, privacy is our fundamental priority. Most operations (merging, splitting, editing, rotating, watermark, encryption) are executed entirely in your browser using WebAssembly and Web Workers. Your files never leave your device.
For tools that require server-side conversion (e.g. Word to PDF, Excel to PDF), files are read directly into server memory (RAM), processed instantly, and sent back as a stream. Files are never saved to disk or stored in any database.
We do not use tracking cookies, advertising IDs, or invasive analytics scripts.
AI processing functions run locally using WebAssembly or in-memory pipelines. No document content is uploaded to third-party services or stored for training purposes.
Zero data retention. As soon as processing is complete, memory buffers are released and cleared.
