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). ## **Manually reviewed in this post** - [DIY Unicorn Girls Secret Diary](https://ratings.pixalate.com/insight/apps/com.princessgames.GirlsSecretDiary/GLOBAL/android/GLOBAL) (Google) * * ### The 10 COPPA Rule factors The teacher will indicate the factors they relied upon in their assessment using the 10 factors shown below that reflect the 10 child-directed factors in the [COPPA Rule](https://www.ftc.gov/legal-library/browse/rules/childrens-online-privacy-protection-rule-coppa). *![](https://lh3.googleusercontent.com/30aNBVdKJcGRgal4gjbUy-oFUo-yJbGN9Voi59WjNO3ryRkv1RlTw3wMt4x8saP9c89PJbXjJfEH0E7Y9WmkmWc2vrJchbnFykl7ImkrRDBd4LXx5jEnpb27LcB76ZDCjOMJNmNSf03cMqfuqWF56XOwN4Mkc_yKXukaXRg7TNE3gwj_IZQIj5yp1gcf9w)* ### **Reviewed by: Crystal Pearson** ## **![Crystal Pearson](https://www.pixalate.com/hs-fs/hubfs/Crystal%20Pearson.png?width=781&height=439&name=Crystal%20Pearson.png)** ## **Manual Review: DIY Unicorn Girls Secret Diary** ### Likely audience after manual review ### ![](https://lh7-us.googleusercontent.com/Fs6h0rjXgIVIkn6ayiq73rvxEM4ES7mDIRGtG-QC1fOxUNU7Xnk2NHzP3pwM9EiubBBXFpCVFStAF15QBEVqMU6IiTrQbY4HfoSASDxXCyTPpFanBFLGmGMnValfsVgz4hKY9gp2jFQL4eLEItMqljE)![](https://lh5.googleusercontent.com/QwfLBhZTw5VlLAdH5DRk2KWzHTpEO9hfyrF1t1CyercUsMD_QQUTC1txKExGv2xjqX4wberlFInpuQKn5wLCbdhllJYTUSkWwnipMhzDfNQMv8OC75GQTH-eRwRaGda6jOfA6kfNO1EYZq_771xjyg) - **Google Developer: **[himanshu shah](https://ratings.pixalate.com/discovery/apps/list/android/all/GLOBAL?developerName=himanshu%20shah) - ******Google Bundle ID:****** com.princessgames.GirlsSecretDiary - [Privacy Policy](https://himanshushahapps.wordpress.com/privacypolicy-2/) - ****Crystal’s Take:**** DIY Unicorn Girls Secret Diary is an adorable and fun app created for girls to safeguard secrets and play simple mini games. ### COPPA factors used to determine audience ![](https://lh7-us.googleusercontent.com/HOON9eNzr6I261RfF88ETBwHe-_9R-oK5umXnUXgyy04hpNdY0SGNu0K1xBHj_0Z2RSDaLRm0FmOPMcgHfbyR-0O9Gi1XcwzDWgvH52zhwdzch452e2zqzVr3QeWerhvCVF5DXOtYCVSD2k4x1h6Bjo) and ![](https://lh7-us.googleusercontent.com/Wc3BUaXpgZNusnnFCfCm6PaZf5Fa0a0qFBFILGP_41t9XAP9nWLXeLwUXeJDnYdo81deNP3AE1RpimDErVXkVcosiJxMTZu1RagVzcKRXRNkWgcCcbeuAnjoto0ls8QpVOV_yb7XKsrhn5Z1ZG0A7L0) and ![](https://lh7-us.googleusercontent.com/XrZyZG1Bt20aL4MoPfhn1uCjCSSrotsKzH5DkL3yLbqbRua5W2vlS6djNGk22qJF-4w-1DjcXqUjODIpFwZv7y7xeFg7gIUozQZreDfS5vuOumZs6UHlcB84VEqhfLdtXwqOS8EGLu3Uhte2644nUQI) and ![](https://lh7-us.googleusercontent.com/N-HfbnqgLi-hcv6qR_kZoQCzVHaJJAwXUcLpNdxn5a9FypXd-f559MUbn38C5xvYQrkKlrwL5eJ1aSWd3m2uSY51KYuqaYknDIPWsZt6WJSA-BvdkQM2xKBRU0HMCWVqfdRD-rbweG8FRktacnNzc7Y) DIY Unicorn Girls Secret Diary is a diary for girls to hide their thoughts from prying eyes. Users get to play around with free unicorn games such as puzzles, drawing, coloring, horoscope, moods, unicorn musical toys, emoticon chats, pop it, and do-it-yourself games all within the diary. Users are able to get imaginative and customize the diary’s background with a personalized lock that has a unique identifier. The subject matter, of this app, says, “designed for girls…princess DIY diary for girls,” which shows that the language and other characteristics are directed to children. The visual content and animation have vibrant colorful graphics design with a pink tone which has characteristics of child-oriented activities. This app is a nice simple tool that can be used to articulate ideas and encourage deeper understanding. ![](https://lh7-us.googleusercontent.com/6jsQI90LeXuedvs1FIKjWi8T4rimwXkaWnB1UL5ihvbkwAbXAwSEpFbVz6rNWNKHiO2Ws1UYDcG8aaGcbvMPsHssk-QFNbhBMTkabkVwOjTKJOJv_4IjoRGHTyZ8SqtovsKKwmQTTHJfVZ0yEvl1EM8) The advertisements are played between levels and switching games, such as, “Spago Mini World: Kids Games and Star Maker.” Most of the advertisements are directed to children. However, there are pop-up ads and banner ads directed to a general audience that plays when exiting a game, for example, “ TikTok and Salon Five Nails.” ![](https://lh7-us.googleusercontent.com/7xt9CZPLfb6KquzOGUNtxxLs0k_dJX2JSRURnbMuxRpXrRsSFAYRIQij9fsohsrdeGwD8Zpr_v3Vj_xW_Z7pbB6LYJopVdXt6g7QLDcOxAc82adFWYqEqTPrIfGEb_HPlxaq9L9wSNsCaCF87FaStHQ) The app is rated E for Everyone in the Google Play store. There is no age gate. A review posted in January 2021 on the Google Play store says, “My child likes it.”  In March of 2022, a review posted said, “This app is so cute and so amazing because when my mom tries and open my diary it has a pattern. Another review posted in November of 2021 says, “I love this game it keeps all my daughter’s secrets.” The reviews do not specify age.

Per the MRC, “'Fraud' is not intended to represent fraud as defined in various laws, statutes and ordinances or as conventionally used in U.S. Court or other legal proceedings, but rather a custom definition strictly for advertising measurement purposes. Also per the MRC, “‘Invalid Traffic’ is defined generally as traffic that does not meet certain ad serving quality or completeness criteria, or otherwise does not represent legitimate ad traffic that should be included in measurement counts. Among the reasons why ad traffic may be deemed invalid is it is a result of non-human traffic (spiders, bots, etc.), or activity designed to produce fraudulent traffic.” ** ** *By clicking Download and entering your email address, you are agreeing to our [Terms of Use](https://www.pixalate.com/terms) and have read and acknowledge our [Privacy Policy](https://www.pixalate.com/hubfs/2024-08-20_Pixalate_Privacy_Policy.pdf). *Copyright © 2025 Pixalate** * * * * * * * * * * * * * * * * * * * * * * * * * * * * × ## Subscribe to the Pixalate Blog The first step in ad fraud prevention.
