That means that you alone - not the authors of this software - are responsible for the legal compliance of an application using this or build from this software and/or usage of a device created using this software.

Disclosure: The Paxcounter code stores scanned MAC adresses in the device's RAM, and keeps it in RAM temporary for a configurable scan cycle time (default 240 seconds). After each scan cycle the collected MAC data is erased from RAM. MAC data never is transferred to the LoRaWAN network. No kind of tracking and no persistent storing of MAC data or timestamps on the device and no other kind of analytics than counting is implemented in this code. Wireless networks are not touched by this code, but MAC adresses from wireless devices as well within as not within wireless networks, regardless if encrypted or unencrypted, are made visible and scanned by this code. The same applies to Bluetooth MACs, if the bluetooth option in the code is enabled.

# Privacy disclosure
|
||||
|
||||
Paxcounter generates identifiers for sniffed MAC adresses and collects them temporary in the device's RAM for a configurable scan cycle time (default 240 seconds). After each scan cycle the collected identifiers are cleared. Identifiers are generated by salting and hashing MAC adresses. The random salt value changes after each scan cycle. Identifiers and MAC adresses are never transferred to the LoRaWAN network. No persistent storing of MAC adresses, identifiers or timestamps and no other kind of analytics than counting are implemented in this code. Wireless networks are not touched by this code, but MAC adresses from wireless devices as well within as not within wireless networks, regardless if encrypted or unencrypted, are sniffed and processed by this code. If the bluetooth option in the code is enabled, bluetooth MACs are scanned and processed by the included BLE stack, and counted by this code.
