1. General information

The “Sarotis-NFC” app is designed to minimize the collection and processing of personal data.

2. Data processing within the app

2.1 NFC functionality

The app allows reading and writing NFC tags. The data read from or written to NFC tags is processed exclusively on your device.

Depending on the NFC tag used, the processed data may contain personal information. Processing takes place entirely locally on the device.

No data is transmitted automatically to the developer or third parties at any time. Data is only shared if you actively export or send it yourself (e.g., via email).

3. Data export (CSV) and user-initiated sharing

The app allows exporting data as CSV files locally on the device.

If you send exported files via email or other services, this transfer is initiated by you as the user. The developer has no control over this transmission.

4. Contact by email

If you contact us by email, the data you provide will be used to process your request.

5. In-app purchases

Paid features are handled via Apple App Store and Google Play Store. Personal data may be processed by these providers.
