How to delete your OpenAI account in the Android app: Step-by-step guide to permanently remove data, manage subscriptions, and protect your privacy | – The Times of India

OpenAI accounts provide access to the ChatGPT API and related services. Users can delete their accounts through the ChatGPT Android App, but this action is irreversible, meaning all data will be permanently removed and the email address cannot be reused for new accounts. Account deletion ensures the removal of personal information, chat logs, and API usage records, although some data may be retained for legal reasons. The deletion process involves several steps: accessing the app menu, navigating to settings, going to data controls, and confirming the deletion. Users must cancel any active subscriptions separately, as account deletion does not automatically terminate them. After deletion, users will lose access to all OpenAI services, and their account information will be erased within 30 days, except for legally required data retention. Best practices before deletion include backing up important data, canceling subscriptions, and reviewing linked services.
