In the app (immediate): open Settings → Account → Delete account and confirm. This permanently deletes your account (email/profile from Firebase Authentication) and the analytics identifiers linked to it.
By email: if you can no longer access the app, send a deletion request from the email address you signed up with to jsrksystems@gmail.com with the subject "Earnrise account deletion". We process requests within 30 days.
What is deleted: your account credentials and profile, and the link between your account and analytics data. Alarm data is stored only on your device and is removed when you uninstall the app.
