Privacy Guides: “For most protesters, activists, and journalists, your smartphone is an essential tool you depend on for organizing with your peers, accessing and distributing information, and helping others. It also represents a great risk, as a tool that is easily appropriated by authorities for targeted and mass surveillance. The perennial question when it comes to protests is whether you should bring your phone at all. If you leave your phone at home, that is probably the safest your data will get, and you will be at very low risk of being tracked by mass surveillance tools. On the other hand, your phone is a critical resource when it comes to coordinating with others, getting updates on the protest from social media, or simply documenting what is going on with your phone’s camera. If possible, bringing a separate device like a “burner phone,” an old phone you can reset, or even a regular old-fashioned camera is a much better option than bringing your primary phone. Any data you don’t bring with you can’t be taken from you at the scene. However, getting access to or affording devices like these aren’t a realistic option for many people. Whether you decide to take your smartphone or a secondary smartphone with you to the event, this guide will cover how to maximize that device’s security and minimize risks to your privacy.”
