NNWS Tools

Privacy

The short version: your files and text never leave your device.

What we don't do

  • We don't upload your files, images, PDFs, audio or text to any server.
  • We don't use accounts, logins or cookies for tracking.
  • We don't run analytics, ads or third-party trackers.
  • We don't sell or share any personal data — because we don't collect any.

How the tools work

Every tool runs as code inside your browser tab. When you resize an image, format JSON, or trim a video, the work happens on your own device using your computer's processor. The result is generated locally and offered to you as a download. Nothing is transmitted in the process.

The few things that use the network

A small number of tools download code or models — never your content — from a public CDN the first time you use them:

  • Video toolsdownload the FFmpeg engine (~25 MB) once, then process video locally.
  • Background Remover and Text Behind Image download an AI model (~40 MB) once, then run it locally.
  • PDF tools load a small PDF rendering component from a CDN.
  • Currency Converter is the one tool that needs a live connection: it fetches current exchange rates from a public rates API. Only a currency code (e.g. USD) is sent — nothing personal.

In every case, the images, documents and text you work with stay on your device.

Local storage on your device

Some tools (like the notepad, to-do list and habit tracker) and your light/dark theme preference are saved in your browser's local storage. This data lives only on your device and is never sent anywhere. Clearing your browser data removes it.
