Six short missions with a detective team: fact or opinion? Ad or advice? Photos that lie, who wrote what, what not to share about yourself and chain messages.

Seven lessons about what teenagers really run into: scams in games, clickbait, hidden ads by influencers, AI mistakes, edited screenshots and deepfakes, the recommendation bubble and numbers that mislead.
7 missions · missions of 8 minutes
Younger children get the most out of the missions when you go through them together. Each ends with questions to talk about and one tip for you – and then talking about what your child meets online comes naturally.

The missions also work as a ready-made start to a media literacy lesson. The basics are free; lesson plans come in the class kits.
Free
Show any mission on the board or projector: large text, games for the whole class, controlled with arrow keys or a presenter remote.
Free
A link or QR code for parents with every course. Children need no account and we store nothing about them.
Free
Warm-up at the start of a lesson: one mission on the projector, 5 minutes. Results for the class only, no names.
A 45-minute lesson for every mission: lesson plan, worksheet with answer key, links to media literacy learning goals, homework variants, advice for when a child confides in you, and diplomas for the whole class.
A class pack (€15.90) builds on the children's missions: a ready-made lesson with a worksheet for each mission and diplomas for the whole class – for primary school with Junior Detectives, for lower secondary with Not Falling for It. The course Media Literacy for Teachers: Ready-to-Teach Lessons (€40.00) is for teachers of lower and upper secondary school: four ready-made 45-minute lessons, a final test and a certificate for you.
The missions were prepared by Pavel Cinkeis, MBA, MPA. Among other things, they draw on materials from child helplines and Safer Internet organisations – you'll find the sources on each course page. This does not mean these organisations have endorsed them.
Children don't register and don't enter anything about themselves. Only adults create accounts, if they want to.
The missions contain no ads and no tracking tools from other companies.
Only the browser on the device your child plays on remembers which missions are done. Clearing the site data deletes it.
The name your child writes on the diploma is not sent or stored anywhere.

Cyberbullying, misused photos or strangers who want more than they should – these are things to talk about with children, not to play. In the missions, children learn one thing: tell an adult you trust, or call the child helpline 116 111 (free in most EU countries). For adults:
find the free child helpline in your country (Child Helpline International)
the EU's online safety portal, with links to the Safer Internet Centre in each country
116 111 – for children and students, free and non-stop
The missions for children are free – no ads and no collecting data about children. They are paid for by what adults buy: class kits for teachers, paid courses and gift vouchers.
