Imagine someone offers to help you manage your household budget — and asks to go through all your bank statements, receipts and credit card bills in return. No reasonable person would agree to that. Yet millions do exactly this when they grant a finance app access to their bank account.

Bank access is a power of attorney

When an app reads your account automatically, you no longer control who sees which transaction and when. Account balance, recipient, time and amount of every purchase — all of it lands on someone else's servers. That sounds convenient, but has a price: you give up control over one of the most private data areas there is.

A data breach at such a provider reveals more than numbers. It exposes your spending patterns, your habits, your life circumstances — patterns you may not even be consciously aware of yourself. And unlike a compromised password, a leaked spending profile cannot simply be reset.

CostCrafter does not need bank access. You enter what you want to see — nothing more, nothing less.

External AI means your data trains someone else's models

Many 'smart' budget apps send your receipts and spending categories to external AI services — often from US providers. What looks like a convenience feature means in practice: your purchases, amounts and categories become part of a training dataset you have no control over.

CostCrafter's OCR reads your receipts without transmitting any data to external services. Everything is processed on our own infrastructure within the European Union.

US cloud means US law

Services that host their data with US providers like AWS, Azure or Google Cloud are subject to the CLOUD Act and Section 702 of the Foreign Intelligence Surveillance Act (FISA 702). This means: under certain circumstances, US authorities can access data of EU users — without a German court order.

CostCrafter hosts exclusively on servers within the European Union. German and European data protection law applies without restriction to all your data.

Free usually means you're the product

Those who don't pay fees often pay with their data — either directly through the sale of user profiles, or indirectly through behavioral targeting, partner offers, or recommendation marketing based on your spending behavior.

CostCrafter is a paid service. That is not a disadvantage — it is the business model. We earn money with the software, not with your spending habits. You know exactly what you are paying for.
