The account owner can delete the workspace from Settings, then Plan & Billing. Deletion is immediate and cannot be undone. Everyone on that workspace loses access. Your sign-in profile is a separate step, and only comes up when you have no workspace left.
Open Settings and select Plan & Billing. You can also open Plan & Billing from the account menu.

At the bottom, the owner sees Delete account. The line under it says Permanently remove your workspace and all data. This action cannot be undone.

Select Delete account. The dialog is also titled Delete account and says This will cancel your subscription and permanently delete your workspace. If this is your only workspace, you'll be asked whether to also close your Socialbud profile. This cannot be undone.
Select Delete account to continue, or Cancel to keep the workspace. While it runs, the button says Deleting….

The workspace is removed right away. A trial subscription ends immediately. A paid subscription is set to stop at the end of the current period, so you are not charged again. You do not keep using the workspace until that date.
If you still belong to another workspace, you choose which one to open. If this was your only workspace, Socialbud asks Close your Socialbud profile?
Open Settings and select Plan & Billing.
Select Delete account.
Read the dialog. Select Cancel if you want to keep the workspace.
Select Delete account to remove it.
If you see Close your Socialbud profile?, choose one:
Yes, close my profile permanently closes your sign-in and the data tied to it. The button says Closing… while it runs.
No, keep my profile leaves your sign-in in place. You will not have a workspace until you join or create one.
Only the owner can delete the workspace. A manager or a member sees Leave account instead. That removes only you. The workspace, the plan, and the other people stay.
Leave account says You'll be removed from this workspace. If this is your only account, you'll be asked whether you also want to close your Socialbud profile. Select Leave account to confirm, or Cancel to stay. While it runs, the button says Leaving….
You cannot remove yourself from Members. Leave from Plan & Billing.
Deleting the workspace does not refund the current period. See Refund Policy if you are within 7 days of the charge.
If you only want fewer emails, open the account menu, select My Profile, and turn off Email alerts. You do not have to delete the workspace.
You do not see Delete account. You are not the owner. Use Leave account on Plan & Billing. The owner is the one who can delete the workspace.
You see "Only account owners can delete the workspace." Ask the owner to delete it, or leave the workspace yourself.
You see "Deleting this account is only available from the admin panel." This view cannot delete the workspace. Open the account as its owner.
You see "Failed to delete account" or the button returns to Delete account. The workspace is still there. Try again. If it still fails, contact us. Do not assume the subscription was cancelled.
You selected No, keep my profile and now have nowhere to work. Your sign-in is still active. Join a workspace you are invited to, or create one, to continue.
Does deleting the workspace close my sign-in? Only if it was your last workspace, and only if you then select Yes, close my profile. No, keep my profile keeps the sign-in.
Can I get the workspace back? No. Deletion cannot be undone.
Will I be charged again? No. A trial ends immediately. A paid plan is set to stop at the end of the period you already paid. Access ends when you confirm Delete account, not at the end of that period.
