Summarize this article in one sentence.
Web browsers will record a history of sites visited by default. Your parents can check the history window to see all sites that were visited during a certain time period. Go into the settings of your web browser to delete the history. You can delete individual websites or clear the entire browsing history if preferred.   In Google Chrome, go to Settings, followed by the History tab to access History settings. You can also navigate Privacy settings here.   In Microsoft Edge, go to Settings and click on “Choose what to clear.” You can choose from several different types of files to clear, including browsing and download history.   While it’s possible to keep browsers from tracking history altogether, your parents will likely notice this setting when they attempt to access their own history. If the browser supports multiple users, make sure that settings are unique to each user. Otherwise, it’s best to delete only particular pieces of browsing history. Move files you are trying to hide, such as chat logs or passwords, into folders that require passwords to access. Remove the files from plain sight – the idea is to make finding the files as difficult and oblique as possible.   Rename the file into something innocuous that doesn’t give away the purpose of the file. “Passwords.txt” is a bad choice! Files can also be hidden in file folders for existing programs that otherwise have nothing to do with your chat logs or passwords, such as the data folder of a game application. Files can be made invisible with the “hidden” property on Windows OS. You can find this option under the Attributes field in file Properties.   Hiding files in a similar fashion on Mac OX is a bit more complicated – it may be easier to physically hide the file in this case.   Cloud services such as DropBox or OneDrive can store your files while also requiring additional login steps to help reinforce your security. Give your phone a password to prevent your parents from having access to your texts and phone call history. If you have to leave your phone laying around to take care of a quick errand, make sure to put the phone to sleep in order to enable the lock. It’s a good idea to keep your phone on your person at most times.   Use a unique password this is difficult or impossible to guess. Use a combination of letters, number and special characters when possible.  Consider fingerprint unlocking if your phone supports the feature. This provides an extra layer of security to your phone. For additional security, apps such as Snapchat can help you delete texts and photos automatically if you don’t want them to be discovered. Facebook, Instagram and other social media sites you use should be kept private. This will keep your parents (or others) from finding your account and freely viewing your messages and photos. You’ll have to add them to your network for them to see your activity.   Make a second, family friendly account if you are concerned about your family seeing certain activities, but don’t want to shut them out of your social accounts completely. Adjust your sharing settings. Facebook offers selective sharing options that can help filter out who gets particular access to your photos and posts. If your items or chat log does get find out, be ready with a believable excuse. Parents aren’t necessarily prone to believing such stories, but depending on the item and the nature of your friends, you might be able to create a convincing argument. Just don’t throw your friend under the bus!   A few examples include, "I'm keeping that for a friend,” or “A friend grabbed my phone and took these pictures.” Use a friend that your parents don’t know in your cover story. You don’t want your parents to give your friend’s parents a call and blow your cover.
Delete your web history. Hide files properly. Lock your phone. Keep your online accounts private. Have a cover story.
