4. Data Storage

User data is stored on Google Cloud (Firebase Firestore). While we take appropriate security measures to protect data, we cannot guarantee complete security over the internet.

AI comments generated from "Today's Condition" are stored on the server together with the entered information. The AI coach chat feature ended on September 26, 2026. All chat-related information stored on the server (usage timestamps and conversation summaries) will be deleted after the feature ends.

For service improvement, we may use anonymized training data, AI analysis results, and AI comments for statistical analysis. Anonymized data cannot identify individuals. Anonymized statistical data may continue to be retained after account deletion.

5. Use of Cookies

This service uses Firebase Authentication session management to maintain authentication state.

We also use Firebase Analytics (Google Analytics 4) to understand and improve service usage. This stores analytics cookies (_ga, _ga_*, etc.) in your browser. Collected data is anonymized and does not identify individuals.

We do not use advertising tracking cookies.
