Subs4What stores only your email address, an account identifier, and your supporter number.
From the app (recommended): open Subs4What and go to Account → Delete account. This permanently deletes your account and all associated data immediately.
If you can no longer sign in: email support@fixmelabs.com from the address
you used to sign up and request deletion. We verify ownership before deleting.
Deleted account and supporter data cannot be recovered. We do not retain account data after deletion.
