Delete Your NightOwl Account
Last updated: September 30, 2026
You can permanently delete your NightOwl account (by Contrast Softwares) and all the data associated with it at any time. There are two ways to do it.
Option 1: Delete in the app (immediate)
- Open NightOwl and sign in to the account you want to delete
- Go to the Settings tab
- Scroll to the Account section and tap Delete Account
- Confirm. Your account and data are deleted right away and you are signed out
Option 2: Request deletion by email
If you no longer have the app installed or can't sign in, send an email:
- To: contrastsoftwares@gmail.com
- From: the email address you use to sign in to NightOwl (so we can verify the account is yours)
- Subject: Delete my NightOwl account
We'll confirm by reply and complete the deletion within 30 days of your request.
Subscriptions are not cancelled automatically. NightOwl Pro subscriptions are billed by Google Play. Deleting your account does
not cancel a Google Play subscription — please cancel it first in the Google Play Store app under
Profile → Payments & subscriptions → Subscriptions, or at
play.google.com/store/account/subscriptions.
What gets deleted
- Your account and sign-in record (email address and display name)
- Your chronotype quiz answers and result
- Your sleep/wake schedule and caffeine habits
- Daily logs (sleep, wake, and caffeine records) and energy check-ins
- Weekly reports and monthly summaries
- Your notification preferences and subscription status record
What may be kept
- Purchase records held by Google Play and our subscription provider RevenueCat, which they keep under their own policies for billing, tax, and fraud-prevention purposes. These contain an anonymous user ID and purchase history, not your NightOwl data
- Data cached on your own phone is removed when you sign out or uninstall the app
We don't keep backups of deleted account data beyond our database provider's short rolling backup window, after which it is gone for good.
