Koura Diary / Privacy Policy
Privacy Policy
Last updated: 2026-06-27
This English text is provided for convenience. In case of any discrepancy, the Japanese version prevails.
This policy describes how user information is handled in “Koura Diary” (the “App”).
1. Information We Collect
- Records you enter: Animal profiles (name, species, sex, adoption date, etc.), weight, carapace length, temperature/humidity, food, excretion, notes, photos, and so on. These are stored in a storage service (Google Firebase: Firestore / Storage).
- Account information: The App starts with an anonymous account. To carry over data or share with family, you can link an Apple or Google account. Authentication is handled by Firebase Authentication, and the App uses the user’s identifier (user ID) as the owner of records. Email addresses and the like provided by the sign-in provider (Apple / Google) are used for authentication; the App does not independently store or use them.
- Nickname (display name): To show whose record is whose in household (family) sharing, a nickname you optionally set is stored.
- Error / diagnostic information (crash data): When the app terminates unexpectedly, information (location of occurrence, device model, OS version, etc.) is collected by Firebase Crashlytics. This is for quality improvement, not to identify individuals. It is not collected in development (debug) builds.
- Abuse prevention: Firebase App Check verifies that access comes from a legitimate, untampered app. This confirms device legitimacy and is not personal information.
The App shows no ads. It performs no advertising-purpose tracking or advertising-identifier collection, and does not use analytics.
2. Purposes of Use
- Storing, displaying, and analyzing care records (dietary-balance guides, body-condition guides, etc.)
- Account authentication, data carry-over, and sharing within a family (household)
- Understanding issues and improving the App’s quality
3. Sharing within a Family (Household)
The App lets you create a “household” and share records with family. When you share a household, the records, photos, and animal profiles of that household can be viewed and edited by invited members of the same household. Choose whom to share with at your own discretion and responsibility. You can also leave a household.
4. Provision to / Entrustment to Third Parties
The App uses the following external services (Google LLC) for storage, authentication, and quality improvement, and the above information is transmitted to and stored by them. Each company’s privacy policy applies, and data may be processed on servers outside your country.
- Google Firebase (Firestore / Storage / Authentication / Crashlytics / App Check)
The App does not sell or provide user information to any other third party (except as required by law).
5. Notifications
Notifications such as reminders are delivered as local notifications on the device. No personal information is sent to a server for notifications.
