Overview
RF Toolbox provides amateur radio and RF engineering calculation tools. It does not require an account and does not include advertising or analytics in the current version.
Location Data
If you use GPS Location, the app requests location permission to display your coordinates and calculate a Maidenhead grid square. Location is requested only after you start that feature and is not intentionally transmitted to our servers.
Local Device Storage
The app stores favorites, calculation history, theme preference and Pro access state locally on your device. You can clear favorites and calculation history in Settings.
Network Requests
Solar & Propagation retrieves public solar flux and planetary K-index observations from NOAA Space Weather Prediction Center. As with normal internet requests, NOAA and network providers may receive technical request information such as an IP address.
Purchases
When in-app purchasing is enabled, purchase processing and restoration will be handled by the applicable app store. RF Toolbox does not collect payment card information.
Changes and Contact
This policy may be updated as app features change. For privacy or support questions, contact tech@clk.company.
