I agree with chantik's comment, get a separate phone. While you are doing that get a separate set of logins that you use on that phone, use a separate email for punting as well. If you want security - keep everything separate, I have learnt this through painful experience my friend.
Apps tend to replicate and synchronise across devices - sometimes it it isn't obvious- & when you use your phone it will replicate some things onto other devices, even if you delete conversations they don't always delete on every device AND they are easily recoverable. You will want to close all that off if you want to keep your punting a private affair.
Of course now you need to hide your second phone
