What is free, what is paid, and why
Every lesson is free for 7 days for your child’s school year. A subscription keeps everything open, for every year. Here is exactly what each one includes.

The lesson is open to everyone: its picture, its text and, from age 8, its quiz.

The text stays readable. The picture and the quiz open with a subscription.
For your child’s school year, each new lesson is free for 7 days after publication. Fresh free content becomes available as new lessons are published. The free plan remains available with no time limit.

Teachers: publishing lessons to your class is free, and will stay free. Families receive them without a subscription. For teachers
For review throughout the year
The yearly subscription costs €29.99, compared with €51.48 for 52 weekly payments of €0.99, a saving of 42%. For a week of review during school break, the weekly option starts at €0.99 and includes the same access. Both subscriptions can be canceled anytime; access continues until the end of the paid period. Your store shows the price in your local currency.
A subscription opens every school year, not just your child’s. That is deliberate: siblings are not the same age, a child ahead in one subject is behind in another, and a Year 5 pupil who wants to revisit something from Year 3 should be able to without it costing a second subscription.
Schools
Primary and secondary schools and training centres have a separate offer at €9 per learner per year, invoiced directly to the institution, with no in-app payment, deployed through Apple School Manager. See the Schools Edition.
Transparency
Subscriptions are billed by Apple or Google, which take their commission. What remains funds producing the lessons, hosting, and development time. There is no investor behind this project and no data resale: subscriptions are the only thing keeping it alive.
Frequently asked questions
Can I subscribe for just one week during school break?
Yes. Choose the €0.99 weekly subscription in the app. For just one week, cancel its renewal in the App Store or Google Play before the next billing date. You keep access until the end of the paid period. Unless canceled, the subscription renews each week. Your store shows the price in your local currency.
Is the free version really free?
Yes, and it is not a trial: it stays available for as long as you like. What is free: every lesson for your child’s year for the 7 days after it is published, the text of every lesson, a lesson’s quiz while the lesson is open (from age 8), and the lessons your child’s teacher shares, 7 days each.
What happens if I stop subscribing?
The app goes back to the free version: lessons older than 7 days show their blurred picture again, their text stays readable, and new lessons for your child’s year stay open for 7 days, as they do for everyone.
How does an illustration request work?
With a subscription you can request one illustration a day on the idea of your choice. It is prepared in a batch and usually arrives by the next morning. An unused request does not carry over to the next day.
How do I cancel?
On iPhone, iPad or Mac: Settings, your name, Subscriptions, then Mon Prof Augmenté. On Android: Google Play, your profile, Payments and subscriptions, then Subscriptions. Cancelling takes effect at the end of the period already paid.
Are there ads?
Never on a child’s profile, subscribed or not: the app is for children, and putting ads in front of them would be a bad idea on every level. A parent or teacher profile without a subscription sees one banner recommending other independent apps: it tracks nobody and receives no identifier. A subscription removes it.
