How do I delete my account?
You do not have an online account. You also do not have a subscription - Daylio is one-time purchase.
Daylio stores the data locally on your phone or on your Google Drive. If you want to remove everything Daylio related just uninstall the app and remove the data from your Google Drive. You can find them here: Where are my data when I back up to Google Drive?
We are sorry to see you go :/
