The app promotes a peaceful environment by strictly prohibiting any negative or offensive content, ensuring a stress-free and safe user experience.

One of the main features of いいこと日記 - 優しい人だけのSNS is the ability to express agreement and support by giving "いいね" (like) to posts that users find positive and inspiring.

Users can also send "スタンプ" (stamps) containing up to 6 characters or emojis as a way to react to posts. The sender's identity remains anonymous, encouraging users to send multiple stamps and create a lively and engaging atmosphere.

The app provides a "マイページ" (My Page) feature where users can review their own posts and reflect on their positive experiences. This allows users to keep a record of the many good things they have encountered.

To maintain a positive environment, いいこと日記 - 優しい人だけのSNS includes a filtering system that allows users to set up a list of prohibited words. Any post containing these words will be automatically hidden from view.

Registration is hassle-free and completely anonymous, allowing users to start using the app immediately with ease.

For added security and peace of mind, the app offers a blocking and reporting feature. Users can block unpleasant individuals and hide their posts, as well as report inappropriate content to the app's administrators. Inappropriate posts will be removed, ensuring a safe and enjoyable user experience, regardless of whether a report is made or not.
