個人情報を守る大切さ
1 / 4
個人情報って何？なぜ大切なの？
個人情報っていうのは、君の名前や住所、学校名、顔写真など、「この情報は○○さんのものだ」ってわかってしまう情報のことだよ。プライバシーは個人情報よりもっと広い意味で、君だけの秘密や私生活のことを指すんだ。
もし君の個人情報が知らない人にバレちゃったら、どんなことが起こると思う？迷惑メールがたくさん来たり、家に知らない人が来たりする可能性があるんだ。
一番怖いのはなりすましだよ。悪い人が君のふりをして、SNSに変なことを書いたり、勝手に買い物をしたりするかもしれない。まるで君がやったことみたいに思われて、大変なことになっちゃうよ。
覚えておこう！ 個人情報には、氏名・住所・電話番号・生年月日・学校名・顔写真・SNSのアカウント・IDやパスワードなどがあるよ。
個人情報がもれる危険なパターン
SNSに顔写真や家の近くの写真をアップしたり、よく知らないサイトに個人情報を登録したりすると、情報がもれやすくなるんだ。「プレゼントが当たる！」みたいなあやしいメールに返信するのも超危険だよ。
情報がもれると起こることは本当に怖いよ。住所がバレると知らない人が家に来たり、待ちぶせされたりする可能性がある。君の名前や住所のリストが、悪いことをする会社に売られることもあるんだ。
友達とのメッセージで他の子の個人情報を送るのもダメ。友達の情報も同じように大切に扱わなきゃいけないからね。
注意！ SNSに投稿した写真から、制服で学校がバレたり、背景で家の場所がわかったりすることがあるよ。
こんなとき、どうする？実例で学ぼう
オンラインゲームで知らない人から「本名と住んでいる市を教えて」って聞かれたら、絶対に教えちゃダメ！ゲームに関係ないことを聞いてくる人は、悪い人かもしれないからね。「教えられないよ」ってきっぱり断って、しつこかったらすぐにゲームをやめよう。
友達が君の顔がはっきり写ってる集合写真をSNSにアップしようとしてる時も要注意。「私の顔が写ってるから、のせないでほしいな」って正直にお願いするんだ。どうしても載せたいなら、顔にスタンプを押してもらおう。
君の情報だから、ちゃんと自分の意見を言うことが大事だよ。恥ずかしがらずに、しっかり「ダメ」って言える勇気を持とう！
大切なポイント 困ったことやあやしいなって思ったら、すぐにおうちの人や先生に相談しよう。一人で悩まなくて大丈夫！
個人情報を守るための実践ルール
ネットでは本名じゃなくてニックネームを使おう。知らない人からの友達申請は無視して、SNSのプライバシー設定は「友達のみ」にしておくのが安全だよ。
絶対やっちゃダメなこと：本名や学校名を公開する、知らないメールのURLをクリックする、パスワードを友達に教える、制服姿の写真を誰でも見られる場所に載せること。これらは本当に危険だからね。
写真を投稿する前には、「この写真で自分のことがバレちゃわないかな？」って必ずチェックしよう。一度ネットに出た情報は、完全に消すのがとても難しいんだ。
パスワードは誰にも教えないで、簡単なものにしちゃダメ。何かトラブルがあったら、恥ずかしがらずにすぐ大人に相談することが一番大切だよ！
絶対覚えておこう！ 情報を公開する前に「本当に大丈夫かな？」って一度立ち止まって考える習慣をつけよう。君の安全は君自身が守るんだ！

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
