Frequently asked questions

To show you what things really cost, before you decide. The fees on an investment, the gap between what you put in and what it is worth, what a decision would have cost or earned you: calculations nobody takes the time to do, because they are tedious. We do them for you, from real figures. You decide.

The result of several years of research, made available to you. Our model analyses past prices and derives a complete scenario: a possible buying price, a target, and the level beyond which the scenario no longer holds.
You do not get an isolated prediction, but figures to place a decision: what you are aiming for, what you are risking, over what period. That is enough to plan ahead, without claiming to know the future: no model can, and we do not pretend otherwise.
Anyone can compare the scenarios on offer, and adjusting the thresholds to your own risk tolerance is coming soon.

By looking at its results, which we publish as they are. Every scenario is checked daily against real prices and ends in one of four states: running, target reached, invalidated, or expired. Failures are shown alongside successes. That is rare in this field, and deliberate: a model you cannot check does not deserve your trust.

No, by design. We provide calculations and reference points; the decision is entirely yours, as is the responsibility that comes with it. No content on the site, including the assistant's answers, is a recommendation to buy or sell.

Yes. Projections and the simulator need no account. A free account unlocks the portfolio, the assistant and personalised settings. No advertising, no data resale, no paid partners behind the scenes.

Not to browse projections or use the simulator. An account becomes useful as soon as you want to keep something: your watchlist, your portfolio, your display preferences, and soon your own thresholds.

It connects what you own to the scenarios in progress. You do not just see the value of your holdings: you also see which ones are approaching their invalidation level, which have reached their target, and what each situation means in euros. That link between your holdings and concrete figures is what no other tool provides.

For now yes, and you stay in control of what you enter: you may record quantities only, without ever stating an invested amount. Automatic connection to crypto exchanges and file import are on the way.

Yes, it was designed that way. Stocks, ETFs, savings accounts, cash: each holding has a type and an institution, which also shows you where your money sits. Tracked cryptos are valued at the day's price; for the rest, you enter the value and we date it.

Because it is enough to read your balances and allows neither placing an order nor withdrawing funds. Even at worst, nobody could move your money. We did not want a tool able to act on your behalf.

Your personal data is erased at once: name, email, portfolio, exchange keys. The action is permanent, and you can download everything beforehand, in one click, from the "My data" page.

They are encrypted in our database, as are your exchange keys. In practice, even if someone took the database, they would only find unreadable strings. Few tools go that far for portfolio amounts; we considered it the bare minimum.

With Graphlab, in France. It is never sold, rented or passed on to anyone. Our business model does not rely on your data.

No, and that is a deliberate engineering choice. The AI model runs on our own servers: your questions and figures never leave our infrastructure, and nothing is stored in the database. Calling an external service would have been simpler; we preferred your amounts to stay with us.

Only those that make the site work: your session and form security. Our audience measurement runs without cookies and without profiling. That is why no consent banner interrupts you: we have nothing to ask you to accept.

From the "My data" page in your account menu: one button downloads everything we hold about you as a readable file, another deletes your account. No form to fill in, no waiting period. For anything else: Mickeal Legrand.

Most ask you to imagine an average annual return, then apply a formula: the result depends entirely on the number you typed in. Ours replays the prices that actually occurred, day by day, rises and crashes included. You do not see a smooth theoretical market, but what really happened.

Yes, per-order fees are, at a rate you adjust, and we show what they cost you in total: often the equivalent of several instalments. Currency conversion fees, withdrawal fees and taxes are not included, and this is stated under every simulation.

Because crypto-assets are quoted in dollars. Converting them at today's rate would give a more comfortable figure, but a wrong one: the exchange rate varied over the period too. We prefer an accurate number to a pleasant one.

Because we only use prices we recorded ourselves, and our history currently covers about a year. It grows every day. The period actually available is always shown below the result.

No, never. The simulator shows what happened, not what will happen. Its value lies elsewhere: understanding the effect of fees, of regularity, of entry timing. Those mechanics do hold.

They are highly volatile: their value can fall sharply and fast, up to a total loss of capital. They are lightly regulated, and no public guarantee protects your holdings, unlike a savings account. That is precisely why the simulator always shows the comparison with a French Livret A: so the reference point stays in front of you. Only invest what you can afford to lose.

No. The site places no orders and holds no funds. All your transactions happen at your exchange or broker, under your control.

Yes, like any system of this kind. It describes the figures on screen and never tells you what to do, but its answers are generated automatically and may contain errors. The reference figures remain those on your screens and at your exchange.
