wow, Hive Social won't let you add any photos unless you grant it access to *all* your photos. Normally on iOS you can choose to give an app access to only select photos, but it recognizes this and prevents you from doing anything. Super sketchy, will not be using this.

Once you give it access to all photos, there's nothing stopping it from combing through your camera roll and doing whatever it wants, like scanning your photos for location data, uploading hashes of the images for later matching, or probably worse things I can't think of.
