If you don't want your financial information shared with anyone, don't put it on the internet. Even with a strong privacy policy, do think anyone can guarantee that your data will always remain safe?
I don't put it on the Internet at all. I was just wondering how so many people were praising the site and its features and how this application has so many users with nobody even asking the question about a privacy policy or the developer not thinking about it. Since this is a paid product, a privacy policy is a set of promises that the vendor makes to you as a customer, and is part of the contract with you (which you can enforce or claim compensation for when breached, depending on the jurisdiction).
While nobody can guarantee anything in life, we still expect reasonable policies and protections to be available. Otherwise why would anyone even worry or talk about the Cambridge Analytica scandal? Take this unrealistic example: would you not feel you're being scammed if you bought a flight ticket but the airline had no policy about baggage loss or delays (essentially anything that could affect you, the paying customer, negatively)? It's quite obvious that the airline cannot guarantee that your bags won't get lost or that there won't be delays in the flight times.
The same principle applies with the airline. If you really don't want to deal with the hassle of having your bags lost, don't fly.
Of course, that takes the whole mentality to an extreme.
It's not often, even with a good privacy policy, or lost baggage policy, that it offers any true protection. It is more for peace of mind.
