Choosing a Private Journal App for Android

A journal holds things you would not tell most people. Before you pick an app, check six things: encryption, an app lock, hidden previews, ads, whether an account is required, and the privacy policy.

The checklist

Encrypted entries

Your entries should be encrypted when stored, not saved as plain text.

In Cloudy: Entries are encrypted before they are stored.

App lock

Fingerprint or face unlock stops anyone who picks up your phone from reading your journal.

In Cloudy: Optional fingerprint or face lock.

Hidden previews

Widgets, notifications and the app switcher should not show your words to someone looking at your screen.

In Cloudy: With the lock on, memory text is hidden in widgets and the app switcher preview is protected.

No ads

Ad-supported apps have a reason to collect more about you than they need.

In Cloudy: No ads.

Account is optional

You should be able to try the app without handing over an email address.

In Cloudy: Works as a guest. Add Google or email sign-in later to sync across devices.

A clear privacy policy

Read what data is collected and why. Check the Data safety section on Google Play too.

In Cloudy: The privacy policy is published on this site.
