it's important to me that freecbt is low-maintenance: "contact support" to remove a pincode is not acceptable. I don't know how I'd remove it for someone manually without resetting all data anyway. (verified that "app info > storage > clear storage" removes all data, including pincode)
I'm not even sure I'd want to remove one if I could, for security's sake. for example: alice has an app pincode, mallory has access to alice's phone, mallory asks me to reset "their" pincode, I do so, mallory now has access to alice's data. data loss is better than something like that happening even once.
change this language to something like "don't forget your pincode - to protect your privacy, support can't reset it without also resetting all your freecbt data".
also, there really should be a way to remove a pincode once it's set. enter the current pincode to do so first, of course.
