Sparkasse Rhein-Maas already texts you every time money moves. PennyWise reads those messages on your phone and builds your spending record from them — no manual entry, no bank login, nothing leaves the device.
Everything above is extracted by an on-device parser written specifically for Sparkasse Rhein-Maas's message formats. You can see it run on your own message, without installing anything: open the parser tool and paste in one of your Sparkasse Rhein-Maas messages.
Apps that aggregate accounts ask for your net-banking or account credentials and hold your transaction history on their servers. PennyWise asks for neither. It has no account system, makes no network calls to read your money, and its full source is published under AGPL-3.0 so the claim is checkable rather than promised.
Yes. Sparkasse Rhein-Maas is one of 157 banks and payment services PennyWise recognises. Transaction alerts from Sparkasse Rhein-Maas are detected automatically and turned into categorised transactions in EUR.
No. PennyWise reads the transaction SMS Sparkasse Rhein-Maas already sends you and creates the entry itself — amount, merchant, date, account and running balance where the message includes it.
Never. PennyWise has no login to your bank and no connection to Sparkasse Rhein-Maas at all. It only reads the SMS already sitting on your phone, which is why it needs SMS permission and nothing else.
No. Parsing runs entirely on your device. There is no server, no account and no analytics on your financial data, and the source code is public so this can be verified.
You can paste the message into the parser tool on this site to see exactly what PennyWise extracts, and report it in one click if it is wrong. Parser fixes ship in the next release.
