Sign-in and email verification
When you choose Google sign-in, Google processes your sign-in request and ATSAI receives your Google account identifier, name and verified email address. Google sign-in is optional. Direct email accounts receive verification codes through Resend. We store email-verification status, linked sign-in provider and successful sign-in method and time for account support and security. Verification codes are stored only as protected digests and expire after 10 minutes. Only authorised platform owners can view sign-in reporting. Account deletion removes the associated sign-in metadata and history.
