This disclosure describes techniques to enable users to restrict private data from display. Such private data can include images, videos, documents, and other files, by a user device. Private files can be manually or automatically designated, and the content of these files is hidden from user interfaces provided by application programs. Automatic designation is performed using user-permitted techniques for automatic analysis of files. Further, a variety of settings allow the user to control access to private data for display by designated application programs. Such features restrict another user that is viewing a device screen from viewing private data. Described techniques provide these features in ways that reduce the impact on usability, where authenticated access to private data is easily permitted via displayed prompts.
