Account Deletion
InCosmos Brief supports in-app account deletion.
How to delete
Open the Profile page while signed in, choose Delete Account, and confirm the prompt.
After you confirm and complete any required verification, your account and its synced personal data are removed, and you are signed out.
Apple accounts require fresh reauthorization
If Apple is one of your sign-in methods, verify with Apple immediately before deleting your account.
The service revokes the Apple sign-in authorization for InCosmos Brief before removing your account data.
If you cancel the Apple verification or it fails, your account remains available.
After deletion
Deletion is immediate and hard: the current account, sign-in identity link, active sessions, favorites, reading history, and user- or session-linked outbound event rows are removed as one atomic operation.
A later login with the same email, Google, or Apple identity can start a new account setup. Creating a new account does not restore the deleted personal state.
If you cannot access the app, contact hello@zaiu.jp for deletion support.
