On behalf of my team, we’re all sad to see you go.
But if you are determined, please cancel your subscription first:
On your iPhone:
- open Settings→ [your name]
When doing this, please make sure to open your phone's settings, not the settings inside the Nebula application.
- There you will see a list of all active and expired subscriptions. When you tap on a subscription from the list, you can choose a different subscription option or tap Cancel Subscription.
If you don’t see Cancel Subscription, the subscription is already cancelled and won't renew.
Here's a more detailed guide on that from Apple:
To erase your account and data, just delete the app.
All your data is stored on your phone, so that would be enough.
We will be happy to see you as our customer again.
