The web price is lower.
The app is the same.
Apple and Google charge more to handle the subscription.
Pay on the web and you keep €1 a month: €6 over six months,
€12 over a year.
Both routes activate the same account.
The store handles the payment and takes a larger share.
Most of it never reaches us.
Compared with direct checkout, roughly 85 cents is absorbed by the higher store cost. The remaining 15 cents sits inside normal operating costs.

Where AI is, and where it is not.
The 30 cents in the table above buys language model calls. This is the full account of what they do, so that nothing in our marketing has to be taken on trust.
- The first draft of a goal's steps and substeps, built from the five answers you give.
- Revisions, when you ask for a step to be reworked, split, or replaced.
- The wording inside a generated plan, including step titles and descriptions.
- Every word of the app's interface, this site, and these disclosures.
- Reminder copy, which comes from a fixed set of written templates on a schedule, not from a model.
- Progress, streaks, and completion figures, which are arithmetic on what you ticked off.
- Anything about your account, your subscription, or your money. No model decides those.
The output is generated, and generated text can be wrong. A plan is a first draft produced by a model from a short description of your situation. It is not reviewed by a person before you see it. It can misjudge how long something takes, miss a prerequisite, or state something confidently and incorrectly. Every step stays editable for exactly that reason: read it, then change what does not fit.
It is not professional advice. Lumen is not a doctor, therapist, lawyer, or financial adviser, and a generated plan is none of those things regardless of how the goal is phrased. For decisions with real consequences, ask someone qualified.
What the model receives. The text you wrote for that one goal and your five answers, and nothing else. Not your email, not your other goals, not your history of completions. The provider acts on our instruction as a processor. The providers, and the countries they operate in, are listed in the privacy policy.
What we will not claim. No testimonial, review, or endorsement in Lumen's marketing is generated or invented. There are none on this site today, and if that changes they will be real words from real people who agreed to them. We will not describe a rule as intelligent, and we will not hide a model behind a word like automatic.
A euro is not dramatic.
It is still yours.
Web checkout costs us less. We lower the price instead of keeping the difference.
Your subscription stays on the same Lumen account. Where you paid does not follow you around the app.
Useful estimates, not false precision.
AI and infrastructure costs change with usage. Store commissions vary by platform, programme, and subscription age. These are reasonable monthly averages for an active user.
We will change the table when the averages move enough to make it unhelpful.
