Stay safe with Martin

So nobody tricks you on your phone — 12 lessons per level, practical, no scare stories.

This is not a scare talk and not a two-hour lecture. It is a practical course: password, fake message, phone permissions, a photo, a second gate — and at the end you help the class. Each level has 12 lessons. 关卡 1–2 free, from 3 a parent pays separately from coding. A school can buy a class licence. 证书, no child email.

Three sentences that almost always work: I do not click when it rushes and wants a password. I do not send what you would not put on the headteacher’s board. I tell an adult — parent, teacher, after-school club. You are not a snitch. You are asking for protection.

Four projects: family rules, phone audit, class campaign, a safer profile. 关卡 1–2 are free. From Shadow it is premium. If it is hard to say out loud, Childline-style help exists in your country — in Czechia that is Linka bezpečí 116 111.

速查表

• It rushes and wants a password / code / “verify your account” → I do not click. I open school myself with a bookmark or an address I know.
• A password is a long sentence, not a nickname + year. Each service a different one. A parent watches the vault (password manager). A sticky note on the monitor is not a vault.
• A school account is not for lending. A borrowed account = a borrowed name. 密码 in chat = change it with a parent.
• Do not read an SMS code or 2FA to anyone — not “support”, not a “bank” on the phone. Backup codes stay with a parent, not in photos.
• Photo: if it hung by the headteacher’s office, would you send it? No → do not send. A screenshot lives on, even if it was “just to them”.
• Cyberbullying: screenshot (date visible), do not argue, tell an adult. 学校 deals with it even if it happened at home in the evening.
• Private account is the default. Bio without surname + school + address. Permissions (location, mic) can be switched off. “Always” for location is too much.
• Open Wi-Fi: browse, do not sign in. Live location only for family, not a story. 学校 work backup lives on Drive, not only on the phone.
• On a class poster put a how-to and where to go — not a skull and not a how-to for the scam.

术语表

• Phishing — a disguise. It pretends to be school, a game or “Microsoft” and wants you to type a password.
• Scam — a trick about money, a “prize” or cheap game stuff. If you did not enter a draw, you did not win. An SMS code is a key.
• Doxxing — publishing things about you that you did not want: name, school, address, a chat photo.
• 2FA — a second gate. 密码 + a code from the phone. Even if the password leaks, the account does not. Backup codes with a parent.
• Permission — what an app may use: location, mic, contacts, photos. You can switch it off. A torch does not need contacts.
• 密码 manager — a vault. You remember one main password (or a fingerprint). The rest stays in the vault, not a note called “passwords”.
• Cookies — a trail on the web. Some keep you signed in to school. Optional ones are for ads — those you can refuse.
• Cyberbullying — repeated hurt through messages, groups, photos, being left out. Three steps: proof, no fight, an adult.
