What sensitive PDFs do you hesitate to upload to online tools?

We built RemovePDFPassword.in specifically because we were uncomfortable uploading bank statements, salary slips, and

Aadhaar documents to random PDF tools online.

Everything on our site runs in your browser via WebAssembly — no file ever touches a server. Curious what documents make YOU pause before hitting "upload" on other tools? And are there specific tools or features you wish existed that kept your files private?

Would love real feedback — we're actively building based on what users actually need.
