If you use Venmo or similar money transferring apps, I encourage you to set your transactions to "private".
I have Venmo just for contributing to collections for gifts and other things for work friends.
Many of my contacts and their contacts seem to use it for lots of things, as you can see from their publicly-posted transactions and posted comments.
You could build up quite a profile on someone from this info. Does everyone really need to know everything you are spending money on?
@voltronic hard no for me. What is the use case that, e.g. PayPal (already uncomfortable) doesn't do?
@voltronic Oh, did not know.
I don't allow apps access to my contacts, so... s'fine, just not for me.
