WiFi Widget is an open source Android app developed by me, Janek Zangenberg, alias w2sv (W2SV). The code is available on GitHub - the very webpage you are currently at - under the GPL-3.0 license.
WiFi Widget does not collect, let alone share, data of whichever kind. In-app configurations made by you are stored locally on your device, and will thus remain entirely private. The entirety of your sensible network information, which is displayed on the widget, is not getting stored, let alone shared, either. Instead, it is retrieved, displayed and thereupon discarded.
WiFi Widget requires location access permission if you want your SSID to be displayed amongst the widget WiFi properties. This is due to the fact, that knowing your SSID enables tracking your devices approximate location by means of SSID fingerprinting. By the same token, the "Location: Allow all the time" permission is required, if you want your SSID to be reliably updated from the widget and without opening the app itself, since that means, that the SSID will have to be retrieved from a background process. If granted, the location access permission is exclusively used for the retrieval of the SSID. Neither are records of your devices position created, nor stored, nor shared. Furthermore, the display of the SSID may simply be disabled if you don't need it to be displayed on the widget, or don't feel comfortable with granting location access permission. In that case, location access becomes completely pointless for the functionality of the app, and it'll work perfectly fine without it.
