This is a product description for a privacy screen protector for phones. The screen protector is designed to prevent others from seeing the information on your phone screen by darkening the image when viewed from an angle. It is particularly useful in public places like buses, elevators, and subways where you want to keep your information private. However, it is important to note that the brightness of the screen will be reduced when this protector is in use. The privacy screen protector is made of high-quality 0.013 inch tempered glass that is dust-free and fingerprint-free. It provides daily protection for your phone screen with a hardness of 9H, which is three times stronger than regular glass. The protector is scratch-resistant and durable. The package includes a microfiber cleaning cloth, alcohol swab, and anti-static/dust removal tape for easy installation without any bubbles or residue. This product is ideal for those who value their privacy and want to keep their information safe from prying eyes.
