One thing that happens when you take pictures with your phone is by default it stores a lot of EXIF (Exchangeable Image File Format) Metadata about you on the image. Some examples of the metadata recorded includes information like camera settings (shutter speed, aperture, ISO), date and time, GPS location, and even a thumbnail image. It essentially provides a way to embed details about how and when a photo was taken within the image file itself, but it can ALSO be used to violate your privacy. Example: You take a selfie in your room of your new outfit and post it to social media with your post set to "public" permission so others can share it too. What went with it? Your home address location via GPS. Now your home address is exposed! I created a free app you can use to scrub all of your pictures of this private information before sharing your pictures. It's currently only available for iOS, but I do have plans to release it for Android very soon! iOS app store: https://apps.apple.com/us/app/kloakofinvisibility/id6749253718 source code: https://github.com/Spinsus/KloakOfInvisibility
