Notes on this comparison

We compare published features, not independently tested security. A red cross earns no credit: the feature is unsupported, has a drawback, or is labelled “Not advertised” because we found no claim in the checked sources. “Not advertised” does not prove a feature is absent. An amber dash means documented partial support. A grey question mark is reserved for checks we could not assess and is excluded from the ranking score.

Sealby free & Premium plans

Do calculator vault apps actually work?

A calculator vault can avoid a casual glance. Sealby focuses on what happens after someone recognises the app: encrypted files, separate codes and no visible vault list.

What to keep in mind
  • This is a category, not one product. Do not apply one developer’s features or price to every calculator vault.
  • An app disguise alone says nothing about encryption strength or recovery design.

What Calculator vaults is built for

  • A familiar calculator screen can avoid attention from a casual borrower
  • Many are free to install
  • The disguise is separate from whatever encryption the app may provide

What to consider

  • The disguise can be recognised; these apps are listed publicly as calculator vaults
  • App names, purchase history or storage settings can reveal the installed app
  • An app disguise does not establish how files and backups are encrypted
  • Compare free-tier limits and privacy labels for ads or tracking

The honest verdict

Choose Sealby for private photos, files and notes without an app disguise. If you prefer a calculator vault, check its encryption and privacy label too.

Common questions

Can calculator vault apps be detected?

They can. App listings, purchase history and device storage settings may identify a calculator vault. A disguise can avoid a casual glance, but it does not guarantee that the app or its private storage will stay undiscovered.

Is a hidden vault better than a disguised app?

They offer different kinds of protection. A disguise can be recognized. Sealby stores no vault list or count and lets you open one vault while the others stay locked. The app, visible content and copies elsewhere can still reveal clues; a decoy cannot guarantee safety.
