You can remove your Arrow Jam account and the cloud save attached to it. Progress that exists only on a phone is not an account and is not removed.
Open Arrow Jam → Cloud Save (or Settings) → Delete account. Confirm. That is the fastest path.
If you have uninstalled the app, email us from the address on the account.
To: support@nexoratechs.app
Subject: Delete Arrow Jam account
Body: the email or Google address on the account, and the words “please delete my account”.
We delete the account and synced progress within 7 days. You will get a short confirmation.
