Privacy model

What data nctools sees, what it does not see, and how to verify.

What we see

  • Account email (if you signed up).
  • Subscription state and billing history (if you paid).
  • Anonymised usage events — tool name, page count, duration.

What we never see

  • Your file's contents.
  • Your file's name.
  • Any metadata inside your files.

How to verify

Open your browser's Network tab, run any conversion, and watch. You will see requests only for static assets. Your file never appears in an outbound request.
