2. In short
RF Lotse is a program for Mac and Windows that reads a connected analyzer (RF Explorer) and helps plan radio frequencies. It runs entirely on your computer. It has no user account, makes no internet connection, sends no usage or crash data and contains no advertising or analytics. We receive no data from you through the use of the app.
3. Data stored only on your computer
| Data | Location | Purpose |
|---|---|---|
| Settings, imported frequency lists with channel and room names, loaded scans | Mac: ~/Library/Application Support/RF Lotse/einstellungen.json, Windows: %APPDATA%\RF Lotse\einstellungen.json | restore your work at the next start |
| Measurement recordings and event logs | folder Documents/RF Lotse | your own analysis and playback |
| Program log | Documents/RF Lotse/rf_lotse.log | troubleshooting |
These files never leave your computer and we have no access to them. You can delete them at any time, in the app via "Clear" and ✕ or directly in the file system. If you enter names of people in frequency lists, you are responsible for that data yourself.
4. Purchase and download
If you buy RF Lotse in the Mac App Store or the Microsoft Store, Apple or Microsoft process your data for purchase, payment and download as independent controllers under their own privacy policies. We only receive aggregated sales figures from the stores, no personal data.
For purchases or downloads via our website, the privacy policy of the website at dss-info.de/datenschutz.html also applies.
5. Contact and support
If you contact us by email or phone, we process your details to answer your request. The legal basis is Art. 6(1)(b) GDPR where the request concerns a contract, otherwise our legitimate interest in answering under Art. 6(1)(f) GDPR. We delete the data once the request is closed, unless statutory retention obligations apply. If you voluntarily send us logs or measurement files for troubleshooting, we use them only for that purpose.
6. Links to other websites
The built-in database contains links to manufacturer documents and regulator publications. They only open when you click them, in your browser. From then on the privacy policy of that website applies.
7. Your rights
You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to object (Art. 21). You may also lodge a complaint with a data protection supervisory authority (Art. 77 GDPR); the authority responsible for us is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia. As the app transmits no data to us, these rights in practice only concern contact requests.
8. Changes
If the app changes in a way that transfers data, we will update this policy beforehand and point this out in the app.
