The Kapsolo 2-Way Privacy Filter prevents visual hacking attacks from the left and right at a viewing angle of 60%. The self-adhesive privacy filter is applied directly to the screen according to the installation instructions. The Kapsolo privacy filter covers the entire screen, from edge to edge or in standard size. The filter stays securely in place, leaves no bubbles, and does not shift when you move or close your device. It can be removed without leaving any residue. Stay safe from prying eyes everywhere: on the train, bus, airplane, at the airport, in the office, conference room, café, school, or at home - no worries when using your phone, laptop, or monitor. It protects your sensitive, confidential, and private data from visual hacking attacks, allowing you to work productively and comfortably anywhere. It minimizes blue light by up to 50%. The touchscreen, HD display, and dual-screen functionality remain 100% intact. The filter also protects your screen from scratches, is shock and drop resistant, and prevents dirt, stains, and fingerprints from easily sticking.
