| Be aware of the fact that bringing a device to an interview by itself can generate digital traces. If your phone is on, it may record GPS coordinates, connections to Wi-Fi networks, or mobile towers (depending on settings). If two phones are connected on the same tower for a period of time, this can indicate that a meeting took place. Apps or operating systems may collect data in the background (e.g. weather apps, social media or system updates). IP addresses, MAC addresses of nearby devices, or Bluetooth connections can also unintentionally reveal information about the environment or participant. All this information can later be used to determine where the interview took place and with whom. | Be aware of the fact that bringing a device to an interview by itself can generate digital traces.

| If you are plan on doing interviews with participants, and the topic is (highly) sensitive (e.g. because it is about illegal activities), then you can minimize digital traces during interviews by leaving your phone behind and using dedicated, offline recording device instead. If you must bring a phone enable airplane mode and remove the battery if possible.
