Like everything else, Internet has it`s good and bad side. The most positive side is probably using its potential to find out and learn new things. The bad or better said scary side of internet is the fact that everything you ever posted, sent, shared or googled stays written somewhere in the network forever.

Sometimes even if you have some files only on your phone, a skilled hacker can hack your phone and get access to all of your private data.

Don’t reveal everything about yourself- these are some of the things you should not share with everybody:

• Date of birth
• Explicit photos of yourself or others
• Plans for family vacations (it leaves options for burglars to rob your house while you’re not there)
• Your home address
• Your mother’s maiden name
• Your phone number
• Photo of your house

Never keep your profile public, use the apps smartly, don’t accept friend request from unknown people and set your privacy level to highest possible setting.

If you somehow have an online friend on your social media profile, that you don’t know in person and you think that person is not who he/she is saying, if he/she is talking about inappropriate things, giving you fear, anxiety or if he/she is suggesting a meet up, here is what you need to do:

• Report it to somebody- parent, guardian, older brother or sister; smartest thing you can do is sharing the problem with an adult you can trust
• Do not meet with that person under any circumstances
• Keep all conversations, emails, photos and other files- if this person turns out to be dangerous, this is the evidence you can use to end this type of crime.
