Early Bird Bank ("the app", known as 早起き貯金 in Japanese) is an iOS app provided by an individual developer ("the developer"). This page explains what information the app collects and how it is used.
| Information | How it is collected | Purpose |
|---|---|---|
| Sign-in identifier (ID and email address linked to your Apple ID / Google account) | When you sign in with Apple or Google | Verifying your identity and keeping your data with your account |
| Display name | Taken at sign-in or entered by you in the app | Shown to the members of your room |
| Wake-up records, settings and reward usage | Entered through your use of the app | Providing the app's features (sharing with your room, tallying) |
The app does not collect location, contacts, photos or advertising identifiers, and does not track you across other apps or websites.
Data is stored in Firebase (Authentication and Cloud Firestore) provided by Google LLC, and handled under Google's privacy policy (https://policies.google.com/privacy).
Members of the same room can see your display name, wake-up records and reward usage. We do not share or sell your data with anyone else, except where disclosure is required by law.
You can delete your account and related data (sign-in information, display name, settings) at any time from Settings → Delete account in the app. You will also leave your room. The room's day-by-day records remain in the room, but are no longer linked to your identifier.
Deleting the app alone does not delete data on the server. You can also request deletion at the contact below.
