how many sub user available for each plan?

And I would like to know can sub user delete the submission? 
As I added the subuser for view submission but seem she can press delete submission, 
how can I prevent that?

UPDATE: Effective October 2018 the Sub-User feature has been discontinued and is no longer available for creating new sub-users. If you had been using this feature previously, you're grandfathered. 

 If you would like to have additional users added to your account, please check out JotForm Enterprise.

Helo,

As per our pricing structure, Sub-users per subscription level are as follows:

Free: 1 Sub-account

Bronze: 3 Sub-accounts

Silver: 10 Sub-accounts

Gold: 100 Sub accounts.

Submissions are password protected, that means, when you  want to delete form submissions, you are ask for account password. If your sub-account user has your account password, then she/he will be able to delete submissions. However, even if you give full access to Sub-users, those are not able to delete submissions unless they know the account password.

I hope this information helps.

Regards.
