You can find the Privacy Settings under the Settings menu. Here's what you can do with these settings:

• By disabling Name Visibility you can mask your name and surname during transactions.
• By disabling Contacts Visibility you can prevent other users from seeing you as a Papara user in their contacts.
• Through the Split and Money Requests setting, you can reject all split requests and money requests from other users.
• In the Block Users section, you can block any Papara user. Blocked users won’t be able to send you money, or send you split or money requests.
