What Data Does a Budgeting App Actually Need From You?
TL;DR
A budgeting app functionally only needs to know your income, bills, debts, and spending - it doesn't need bank credentials or transaction history unless it's choosing convenience over minimizing data exposure. Manual entry provides the same numbers with none of that access granted.
Every budgeting app asks for something. Whether what it asks for matches what it actually needs to do its job is a question worth asking before connecting anything.
What the core function actually requires
To calculate what's safe to spend, an app needs to know your income, your bills and debts, your subscriptions, and your goals. That's the full list of inputs the math actually depends on - nothing about that requires your bank login or a live transaction feed.
What bank-linking adds beyond that
Linking a bank account replaces manual entry with automatic import, which is a convenience, not a functional requirement. In exchange, it also hands your full transaction history to the app and whatever aggregator sits in the middle - a real tradeoff, made for the sake of typing less.
How to evaluate any app's request
Ask what the specific data enables. If a request doesn't map to a feature you'll actually use, it's collecting more than the product needs - usually for reasons that benefit them, not you. That evaluation is really the starting point for figuring out the best approach if privacy is a priority for you.
MoneyFlow calculates Safe-to-Spend from manually logged income, bills, debts, and goals - the functional minimum, with no bank credentials or transaction history required.
