Delete your Wi-Fi History

TASK: Go into settings on your phone and delete your Wi-Fi history. Keep only the Wi-Fi spots you use regularly.

WHY: This data will be checked and recorded by Apple or Google if you are on Android. Most public Wi-Fi spots are well known so they can locate you. Many home Wi-Fi locations are also on publicly accessible databases. Just reduce your tracking potential and attack surface by deleting the networks you no longer use, like those from your last holiday for example. Travel light in data terms.
