We are sorry to see you go! We hope it's because you found what you were looking for!
To deactivate your account, open one of Trovit emails and click on the top right corner where it says "Manage your alerts" (shown in blue in the image below). This will direct you to your Email Settings page. There you can unsubscribe from a specific email notification, from all email notifications (by clicking on "Unsubscribe from all" button), or delete your account completely by clicking on the Account menu , and on the option "Deactivate my account".
If you receive mobile push notifications instead of email notifications, then you don't have a Trovit email account, so you just need to deactivate your notifications, in case that's what you are looking for, following these steps.
