Please keep in mind that if you delete your SoundHound account, you can still use the SoundHound app. However, you will no longer be able to access your search history if you change devices in the future. Having a SoundHound account is the only way to ensure that all of your search history and tagged favorites are saved if you ever change devices.
If you'd like to proceed with deleting your SoundHound account, please contact our privacy support team via a ticket submission.
