What your child is actually doing here
A vocabulary trainer with no adverts, no streak manipulation and no engagement mechanics designed to keep a teenager on a screen longer than the work takes.
Short sessions, on purpose
The queue ends. When today's words are done the app says so and stops, instead of finding a reason to serve one more card.
No advertising, no resale
There is nothing to sell here except the product itself. Your child is not the inventory, and their study data is not a dataset that leaves our servers in Germany.
It costs your child nothing
Students never pay. If the school or the teacher has lexilink, so does your child.
