Protecting personal information online — Technology, 7–10 years
Personal information can identify or locate you, so it should not be shared casually. Strong passwords, careful choices and trusted adults help keep accounts and people safer.
What personal information is
Personal information is a detail that can point to a real person, such as a full name, address, school, phone number, password or exact location. A photo can also reveal information through faces, signs or uniforms. Before sharing, ask who needs it, why they need it and whether a trusted adult agrees.
Why privacy matters
The problem is that information sent online can be copied, forwarded or stored longer than you expect. Someone who does not know you may use it to guess a password, contact you or learn where you are. Privacy is not hiding bad things; it is choosing who gets personal details and keeping control of them.
Worked example: choosing a password
“Luca2016” is easy to guess because it uses a name and a year. A better choice is a long, unusual passphrase, such as four unrelated words, with a number or symbol if the service asks for one. Keep it private, do not reuse it for every account and use a password manager with an adult’s help if possible.
Trap: a familiar detail is safe
A reasonable mistake is using a pet’s name, birthday or favourite team because it is easy to remember. It feels personal, but those details may be visible in posts or easy for someone to guess. Remembering a password matters, yet length and secrecy matter more than making it familiar.
Where privacy choices matter
Privacy choices matter in games, messaging apps, video sites, shared tablets and school projects. Check who can see a post, avoid opening surprising links and tell a trusted adult if someone asks for secrets or personal details. These habits reduce risk, but no setting makes every online situation completely safe.
