A subscription that keeps going · البرمجة مع مارتن

It keeps going until you stop it

A subscription is spending in a rhythm. A month, a year, a season. The button is once. A parent’s card is again. That is why “only 49” is not 49. It is 49 × months until someone cancels.

A shopper asks: who cancels? Where? And can the envelope carry it next month, not only today?

Vojta turns on music 49 Kč / month for a trial. In three months 147. Amálie: “The trial was a week.” Vojta forgot. A parent sees a statement. A fight. The subscription was not magic. It was a rhythm with no envelope.

A game: a season pass renews. Vojta thought a skin was one-off. Season 2 took again.

💡

In the notebook: name, Kč, how often, who cancels. A calendar on a parent’s fridge > your guess “I’ll remember”.

A rhythm that does not vanish on its own

A trial ends with a purchase if it is not cancelled. Free here can be bait. The date the trial ends belongs with a parent.

Cancelling is not a betrayal of the game. It is an envelope. Who scares you “you will lose everything” is talking pressure. Save what you have, and ask a parent what happens to the season.

A subscription from pocket money must carry the monthly rhythm from Cashier. Weekly pocket money × 4. If it cannot carry, do not take it. Even if it is 50% the first month. The second month is the full price.

The account and the card are still a parent’s. You do not switch a subscription onto “your” email. A child’s email does not belong here.

Amálie wants to shorten it to “it will be fine somehow”. Vojta asks what the lesson A subscription that keeps going is for, when a table can do a sum. A sum does not count respect, a PIN, a trap or an envelope. The core is: A subscription multiplies months. Cancelling is work, not forgetting.

Adults pay the rent. The card, the account and the PIN belong to a parent. A child’s email does not belong here. Pocket-money numbers do not belong on the network. If you break these rules in the lesson “A subscription that keeps going”, you know a word, not the course.

49 × 12 = 588. A game for 199 once. Amálie shows 588. Vojta wanted music the whole year. Then 588 makes sense — with an envelope and a parent. If he wanted a month, cancel before it takes.

For practice: 99 / month, pocket money 80 a week. 99 < 320 a month roughly, but must and a goal eat too. The number 99 is not alone.

Practice numbers, not a bank statement. Amálie has 80 Kč in the want envelope. Vojta pushes a step this lesson can name. When Amálie uses the core, either it waits for a parent, or it fits the envelope. If not, anger and a hole are left — proof of pressure, not that the lesson is pointless.

⚠️

A link “cancel here” from chat is often a fake shop. Cancelling only in settings a parent opens, not in an SMS.

Why this right now

You are in the course Money with Martin, level Shopper. You can write numbers in a notebook or a table, but the topic is money and decisions, not Excel formulas. The account, the card and the PIN belong to a parent. A child’s email does not belong here. Do not put pocket-money numbers on the network.

This is not the Sheets with Martin course. A table may help, but the mark of success is a decision, not SUM.

You will know this lesson by one sentence: A subscription multiplies months. Cancelling is work, not forgetting. When you can say it to a parent or a teacher, you have the core. The rest is practice, not magic.

Returning goods on a subscription is often different from a hoodie. First see that it keeps going. Then a warranty and pressure.

If you skip this, the next lesson in level Shopper will stand on fog. 49 × 3 and × 12 is on paper. The rhythm has a watcher — a parent. It is not a test for marks. It is a safety net, so “A subscription that keeps going” is not only a heading.

Four things you will build from the course

The course has four small projects. You do not have to do them all at once. Today you add only what this lesson can do.

🪙 Pocket money

A 14-day record: income, spending, balance. What you do not write down is as if you did not spend it — and that is a lie.

Pocket money: a subscription as repeated spending in the notebook, not a one-off 49.

🚌 Class trip

A budget, a reserve, a plan B. A shared till has rules.

A trip: “a park membership for a year” vs. one ticket. Time.

🎮 Game shop

V-bucks and a loot box are a purchase. A subscription keeps going.

A game pass: this is a subscription in game skin.

🧾 Stall / mini-company

Cost, price, profit. Three numbers for the class.

A stall: a monthly “lemonade club” at school usually not. A one-off cup is cleaner.

Workshop: one rhythm on paper

A practice 49 Kč / month. Multiply by 3 and 12. Who would cancel?

49 × 3 and 49 × 12. Write it.
A notebook row: how often, who cancels.
With a parent: do they have a subscription that concerns you (no amounts on the network)? Only yes/no and who watches it.
A sentence: “A trial ends with a purchase if we do not cancel.”

You count with multiplying. 49 with no × months is a lie of the eyes, the same as a discount with no base.

Pocket money: Pocket money: a subscription as repeated spending in the notebook, not a one-off 49. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Class trip: A trip: “a park membership for a year” vs. one ticket. Time. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Game shop: A game pass: this is a subscription in game skin. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Stall: A stall: a monthly “lemonade club” at school usually not. A one-off cup is cleaner. Do not write someone else’s amount, a PIN, an IBAN or “how much a classmate gets” next to it. A rule and a practice number are enough — or an honest zero.

Practice: once, or again?

Spot the rhythm.

49 now, it takes every month. How much in a quarter year?
A trial week. What happens if nobody cancels?
A cancel link from an SMS. Why a parent, not a click?
Why does a child’s email not belong on a subscription?

Now you 💪

Go through three checks. By each one, tick in your head: do I see it, or not?

I can multiply months, not only read 49.
Cancelling has a person and a place.
I do not take a fake cancel link from chat.

If something is missing, go back to the steps above. It is not a test for marks. It is a safety net, so you go on with certainty, not with a mess.

✅

Check: 49 × 3 and × 12 is on paper. The rhythm has a watcher — a parent.

What to take from this lesson

A subscription is spending in time.
A trial with no cancel is a purchase.
A first-month discount does not lie about the second.
A parent opens cancelling in settings, not in an SMS.
الاسمs in the examples (Amálie, Vojta) are made up. Do not put your number, email or photo here.
Next lesson: When you can do this, go to the next lesson in the same level.
