In the Android app
Sign in with the same account you use on ascenraspace.com. Open You, then Settings. Scroll to Delete account, enter your password, and confirm.
This closes the account on the website and in the app. Google Play subscriptions must be cancelled in Google Play if you subscribed there.
On the website
Sign in at ascenraspace.com, open Account settings, then use Delete account. You will be asked for your password.
Deletion removes your sign-in and personal profile fields. Public posts may remain under a deleted-member label so replies still make sense, as described in the Privacy Policy.
