1. Data Controller Controller as defined by the General Data Protection Regulation (GDPR): Marco Pohl Düsterfurtweg 10 46569 Hünxe, Germany Email: mpohl96@gmail.com
2. Principle of Data Minimization Protecting your privacy is our highest priority. The "Tool Assistant" app (including the associated Apple Watch app) is designed to function without the collection, storage, or transmission of personal data. No registration or login is required.
3. Processing of Sensor Data In order for the app to perform its functions, it requires access to certain sensors on your device:
Camera: Used exclusively for the AR laser plumb function to overlay the camera image with graphic elements.
Microphone: Used exclusively for measuring sound pressure levels (decibels).
Motion Sensors (Gyroscope/Acceleration): Used for the spirit level and angle measurement functions.
Important: All sensor data is processed locally on your device in real-time. At no time is this data (audio, video, or motion data) stored, recorded, or transmitted to external servers. The legal basis for this processing is Art. 6 (1) (b) GDPR (performance of a contract).
4. In-App Purchases (Pro Version) The purchase of Pro functions is handled via the Apple App Store (Service Provider: Apple Inc., One Apple Park Way, Cupertino, California, USA). The controller of this app does not receive any payment or credit card data from Apple. We only receive an anonymized confirmation of the successful purchase to unlock the functions within the app. Apple's privacy policy applies.
5. Analysis, Tracking, and Advertising This app does not contain any analysis tools (such as Google Analytics), does not use ad tracking, and does not display advertising banners.
6. Your Rights You have the right to access, rectification, erasure, and restriction of processing. However, since "Tool Assistant" does not store any personal data on its own servers, we do not have any data that we could export or delete. For questions, please contact the email address provided above.
