You can modify your preferences for alerts on the "myTrovit" section in the Trovit webpage. You can access to your profile any time on the top of our website. Just log in to edit your data or your alerts. Keep in mind that you will have to be registered with an email address to be able to manage your alerts.
Please, consider that it is a relatively common mistake to mistake push notifications for alerts. While alerts are emails sent to your inbox, push notifications warn you when there are new ads that match your criteria. Alerts get stored in your inbox while push notifications are not saved anywhere.
