### 1/5 — Very intrusive app. They collect your personal data

*2023-08-22*

They collect info about you, they spy on you everywhere. Instead, use a simple calculator formula or google the percentages. If you are too lazy and wants this app then ok, otherwise you could easily do same calculations with basic arithmetic. 
I do not recommend this app. I highly recommend you NOT to download this personal data harvesting app.

**Developer response:** Hello and thank you for your feedback. First of all - we gather no personal or sensitive information. If someone does in our name - it is fraud. Always keep that in mind!

Let's explain what exactly happens. We get some anonymous data to check the app performance and crashes. If any problems occur we will find out by some monitoring tools (e.g. Firebase). Maybe it is confusing that we get some unspecified geo and device data. The geo data only show the country where any app session happens. We provide our apps in 11 different languages and worldwide. The geo data help if some issues occur like language based malfunctions. The device data show which kind of device is crashed and how many times it crashed. This helps to better define the underlying problem.

That is all what we do. Apple collects a lot of data of your purchase behavior, your app activity, download behavior, crashes, etc. We can't influence that.

I hope this has provided some clarity. Thanks for checking our GDPR information. This rarely happens. Kind regards.

### 1/5 — App doesn’t do much

*2023-07-12*

Not worth paying for. This app does very very little.   It’s actually easier and faster to use paper vs this app.

**Developer response:** Hello rhythm9, thank you for your comment. The approach of the app is to show each step. It supports those who have not been taught how to do this correctly. So we help out there. But you are right. When you are PRO, you simply do this immediately in your head. But let's be fair. Most people need to work hard to make progress in math. We just try to help.

We provide apps with more complex math topics. How about giving them a try? I bet you are not faster on paper vs this app: https://apps.apple.com/app/factoring-quadratics-pro/id1494505052
