Cubbylock vs Locked Notes on iPhone: Which to Use?

CompareUpdated 2 min read

Short answer: If your private items are text, checklists and scanned pages, a note locked with a separate Notes password is free and good enough. Choose a vault app when you need PDFs and other files behind the same lock, or want everything in one place. Cubbylock is in development, designed for that second case.

When Apple Notes is the better choice

  • You only need to protect text and scans.
  • You want the notes on your iPad and Mac too.
  • You’d rather not install another app.

Set it up with a separate password: how to lock notes on iPhone.

When a vault app fits better

  • You keep PDFs, contracts or ID files that a locked note refuses.
  • People close to you know your iPhone passcode, and you’d like one code for everything private.
  • You don’t want even note titles visible.

What neither protects

  • Someone who watches you type your code.
  • Copies you left elsewhere: the original email attachment, a screenshot in Photos, a file in Downloads.
  • Your data if you lose every way to unlock it. That is how real encryption works.

Frequently asked questions

Is a locked note safe enough for private information?

For text and scans, yes, if you use a separate Notes password rather than your iPhone passcode. Apple says locked notes in iCloud are end-to-end encrypted.

Why use a vault app if Notes can lock notes?

Because a locked note can't hold PDFs, audio, video or iWork files, and its title stays visible. A vault app keeps files and notes together behind one separate code.

Can I keep PDFs in a locked note?

No. Apple doesn't let you lock a note that contains a PDF, audio, video, or a Pages, Numbers or Keynote file. You can lock the PDF itself in the Files app instead.

Is Cubbylock available?

Not yet. Cubbylock is in development, and this page compares Apple Notes with how Cubbylock is designed.
