welcome to HN. i personally think "worthless" might be just a bit rude but the H does stand for hacker, so naturally the audience would be interested in the technology you employ to keep their data safe.
That would be "Designers living in vaccum."
You need to decide if you are a designer or a co-founder, and if you are owning the product or merely contributing to it. Because designers shouldn't be making public comments on product privacy policies.
He mentioned I should know the stack. Privacy policy was not mentioned. Nor did I say being a designer has anything to do with Privacy Policy.
I said, being a designer I do not understand what stack it is and that doesn't make the app worthless.
BUT...
What else do you call a financial application which hasn't set its cornerstone as data protection.
I saw this app and thought it looked nice, I could see myself using it. I then read a bit more about it in the FAQ and I cannot use it. My financial data may not send the world into an economic downturn but it is something I care about and what to keep safe. If this application cannot do that then I cannot put my financial details into it...
If this was sorted out the app would look very promising. Such an apparent disregard for data protection isn't acceptable for a financial app and in its current state looks like it shouldn't be used.
