Terms of Sale

Last updated: 26 September 2026 (payment: card registered when the quote is accepted, charged at the debrief; no work before the withdrawal period ends). Previous updates: 22 September 2026 (deletion of your file when there is no debrief — the three moments named, and fourteen days without a reply after the quote); 4 September 2026 (the Sextant in-depth audit is now sold; its terms are given in the quote)

The Sextant in-depth audit is sold at a fixed price of 400 €. Its terms — price, the turnaround specific to your file, the provider's identity and the mandatory pre-contractual information — are given to you in writing in the quote, before any order. We examine your file before issuing that quote: if the four core measures cannot be computed, you are charged nothing.

The other offers described in earlier versions of these terms — training, automated trading software, subscriptions — are not available; the articles governing them were removed on 28 August 2026. Separate terms of service will be published before any other new service is sold. The instruments available on this site are free and require no account.

Notice — Sextant operates under French regulation. This page is an English translation of the French original. In case of discrepancy, the French version prevails. Original (authoritative): cgv.html.

⚠️ IMPORTANT WARNING — LIABILITY LIMITATION

Trading and investing in financial markets carry significant risks of capital loss, up to the total loss of your investment.

We are NOT an investment advisor and are not regulated as an investment services provider. The content and tools offered are strictly educational and in no case constitute personalized investment advice.

Past performance does not guarantee future results. You are solely responsible for your trading decisions and capital management.

1. Purpose and Scope

These Terms of Sale (hereinafter "Terms") govern the contractual relationship between:

  • Sextant, hereinafter "the Provider", offering market educational content on performance measurement and freely accessible calculation instruments;
  • Any individual or legal entity using the services offered, hereinafter "the Customer".

By using our services, the Customer acknowledges having read these Terms and accepts them without reservation.

1 bis. Sextant In-Depth Audit (400 €)

Purpose and price

The Sextant In-Depth Audit is a written report measuring, from the transaction history you send us, your net performance, your fees, the buy & hold comparison and the concentration of your result. It comes with a 45-minute spoken debrief. The measurement method is published at /en/schema: you can redo every calculation.

The price is 400 € (four hundred euros), a fixed amount, with no subscription and no renewal. Provider: Sami Hannai, sole trader, SIRET 980 723 613 00017. "VAT not applicable, article 293 B of the French General Tax Code" — the amount invoiced is net, with no gross/net distinction.

These terms cover this service only. No other offer is sold until it has terms of its own.

Ordering

You send us your file by email. We examine it before issuing any quote: if the four measures above cannot be computed from your export, you are charged nothing and we tell you why.

If your file allows it, we send you a quote stating the price, the description of the service, the turnaround specific to your file, our identity, and the pre-contractual information required by article L221-5 of the French Consumer Code. The contract is formed when you accept that quote in writing.

Payment

When you accept the quote, you register a bank card with Stripe, our payment provider, and you authorise us, through a checkbox, to charge it once, and once only. We do not keep its number. No amount is taken at this stage.

The €400 price is charged to that card at the debrief, against the invoice, which is sent to you by email. If the charge is declined, the invoice remains payable through the link it contains, within fifteen days.

You may withdraw the charge authorisation at any time by writing to us; without another payment method agreed before the debrief, the audit does not take place. If you exercise your right of withdrawal, or if the audit does not take place, no charge is made and the card is deleted at Stripe.

Right of withdrawal

As the contract is concluded at a distance, you have a fourteen-day right of withdrawal from your acceptance of the quote, with no need to give a reason (article L221-18 of the French Consumer Code).

We do not start producing the report before that period expires. The turnaround stated in the quote runs from its end.

What we undertake to do

We are bound by an obligation of means, not of result. Once your file is accepted, the four core measures are guaranteed, following the published method. The additional measures depend on what your export contains, and the report states which ones could not be produced.

Deliverables: the written report, handed over at the 45-minute video debrief. The turnaround is stated in the quote.

Your data

Your file is used solely to produce your audit and is deleted within thirty days of the debrief. If there is no debrief, it is deleted as soon as we know there will be none, together with the files we derive from it in order to read it: immediately if your export does not allow the four core measures, our answer being final in that case; as soon as you decline the quote; and, if you do not reply, fourteen days after the quote was sent — a deadline the quote itself states, after which you will need to send us your file again should you decide to proceed. We then keep the reasoned answer alone: what was counted, what could not be measured, and why. The report and the method parameters are kept without time limit. Full information on how your data is processed is given to you when we ask for your file, before any collection.

What this audit is not

The audit measures a past; it steers no decision. It is not investment advice, not tax treatment, not a certification, and it requires no access to your accounts. These limits are set out on the service page and apply to the spoken debrief as well.

Complaints, governing law

Any complaint: [email protected]. As the method is published, you can redo the calculation before disputing it.

This contract is governed by French law and the French courts have jurisdiction — without prejudice, if you reside outside France, to the mandatory consumer-protection provisions of your country of habitual residence, which remain available to you.

2. Intellectual Property

3. Personal Data Protection

Sextant undertakes to protect its Customers' personal data in accordance with the General Data Protection Regulation (GDPR) and the French Data Protection Act.

Hosts and subprocessors: the backend is hosted by OVH SAS (France); the frontend by Vercel Inc. (United States). Payments are processed by Stripe, Inc. (United States). Transfers to Vercel and Stripe are framed by Standard Contractual Clauses (SCC) approved by the European Commission (art. 46 GDPR).

Exercising your rights: the Customer may at any time request access to their personal data, its portability (JSON format) or its final deletion, by email to [email protected]. A deletion request triggers a confirmation email valid for 72 hours. Once confirmed, all of that person's data is erased.
