Private Mac Apps That Work Offline

By NUR Technologies · October 30, 2026 · 4 min read

People looking for a “private” app usually want two things: that it does not upload their files, and that it works when there is no internet. They are not always the same. This guide explains the difference and shows which NUR apps offer each.

Private does not always mean offline

An app can process your files on your Mac and still need internet the first time it downloads something. Another can work offline but ask you for an account. Before you trust an app, check whether its page says what happens to your files and whether it needs a connection to work.

What to check before you install

• Where your files are processed: on your Mac, or on a remote server.
• Whether it asks you for an account to use it.
• What happens when the connection drops. Check whether the app page says so.

NUR apps that work offline or keep files on your Mac

• ReadVanced reads EPUB, PDF and more with no account and no internet. AI study needs your AI provider, or Ollama running on your Mac.
• Pomorito runs with no network and no account, and sends no analytics.
• Offcaps transcribes and captions your video on your Mac. Nothing is uploaded.
• Rivet does local OCR and PDF editing. Your files never leave your Mac.
• Simple Archive Converter converts files in bulk. Everything runs on your Mac and nothing is uploaded.

For Offcaps, Rivet and Simple Archive Converter, the promise is that your files are not uploaded. If you need an app to work with no internet at a specific moment, confirm it on the app page before you rely on it.
