You can request deletion of your NoteAI account and associated personal data from the app. Open NoteAI and go to Settings, then select the Delete Account option and follow the on-screen instructions.
You may be asked to confirm your request before your account is permanently deleted. Account deletion and subscription cancellation are separate actions.
If you also want to stop future billing, cancel your subscription separately through the App Store or Google Play. Before deleting your account, make sure you have saved anything you want to keep.
