Pixalate's COPPA Manual Reviews: ‘Unicorn Diary (lock - PIN)'

Jan 24, 2024 11:00:00 AM

Welcome to Pixalate’s CTV & Mobile App Manual Reviews According to COPPA, a series containing the detailed factors the Trust & Safety Advisory Board educators used to assess an app’s child-directedness.

The educators manually review thousands of mobile apps available in the Google Play & Apple App Stores as well as connected TV (CTV) apps from the Roku Channel Store and Amazon Fire TV App Store using the COPPA Rule factors shown below & make those results available to the public at ratings.pixalate.com.

This post takes a look at a popular mobile app (1 million+ downloads) from the Google Play Store. Our reviewer discusses how the subjective factors set forth in the COPPA Rule apply to the app and factor into the reviewer's determination as to whether the app is child-directed or general audience (i.e., it is not targeting children).

Unicorn Diary (lock - PIN) assists in recording your feelings over time.  In the diary, you can compose your day-to-day thoughts and recollections. All of the data can be stored with a secret password and safeguarded with a lock.  The subject matter in the “About this app,” says, “This journal with a lock is suitable for kids and teenagers...this daily journal app for girls is very customizable.” There is gameplay within the diary app such as puzzles, memory, and block games. It is available online and offline. The visual content and animation have a vibrant design with aesthetically pleasing wallpaper, charming stickers to match your day, cool avatars, and a fun unicorn comic.  Overall, the app is geared towards children and offers a space for expression and creativity.

Once the app is downloaded advertisements show up such as “TEMU.” Once you enter a note in the diary, advertisements such as “American Express Business,” pop up. In the banner below while the diary app is open, ads like “Etsy and Lightbox,” are displayed. If someone wants to play a game within the app, there are advertisements that one has to watch such as, “Robokiller,” a phone spam app.  These advertisements are directed to a general audience.

The app is rated E for Everyone in the Google Play store. There is no age gate but there are in-app purchases. A review posted in April of 2021 on the Google Play store says, “So far I like everything…I’m going to suggest this to my daughter.” The review does not specify age.


The developer’s privacy policy states”does not knowingly collect personal information from children under 13 years of age…does not direct any interest-based advertising to children under the age of 13 years of age.”
