What data is processed
Using the calculator
You enter financial and time-related information to obtain a calculation. Those values are sent to the server to process the calculation, without requiring an account. We do not send those figures to Google Analytics. Technical server logs may contain request information; their retention period must be verified before publication.
Operation and security
The site and its infrastructure may process technical data such as IP address, date, browser information and error logs to deliver pages, prevent abuse and maintain the service. A language preference is used to remember ES, FR or EN.
Waitlist
If you choose to join a waitlist, your email address and associated consent are processed to manage registration, confirmation and future project-related communications. Submitting the form does not itself confirm the subscription. You can withdraw your consent and unsubscribe.
Usage analytics
If you allow Analytics, we measure visits and actions such as starting or completing a calculation, opening YouTube content or requesting to join a waitlist. Custom events do not include financial amounts or email addresses.
External services
These companies help provide the functions described below. Their services may involve international data transfers under their applicable terms and safeguards.
- Cloudflare
- Security, DNS and site delivery.
- Railway
- Application hosting and processing calculator requests.
- Brevo
- Email and waitlist management, including subscription confirmation.
- Google Analytics
- Google Analytics 4, for usage statistics when analytics is allowed.
- YouTube
- Links to the channel and an embedded player when you choose to open a video. When you play it, YouTube may process data under its own terms.

Cookies and analytics
The site uses technical preferences required for certain functions and, only with your consent, Google Analytics measurement technologies.
Necessary preferences
A language preference and technical security mechanisms are used. Your Analytics choice is also stored locally so it can be respected while you browse.
Google Analytics
If you accept analytics, Google Analytics may use cookies such as _ga and _ga_* to distinguish visitors and sessions. According to Google, their default lifetime can be up to two years, subject to additional browser limits. Analytics is not used here for advertising personalization.
Change your choice
You can accept or reject analytics and change your decision at any time. Rejecting analytics does not prevent you from using the calculator.
Legal basis
The calculator and the site’s technical security rely on providing the service you request and on the legitimate interest in keeping it available and secure. Voluntary waitlist registration and related communications rely on your consent. Google Analytics requires your prior consent, regardless of the country from which you visit the site.
Data retention
Information is kept only for as long as needed for its purpose, subject to the limits and retention periods of the relevant provider. Waitlist unsubscribes are handled through Brevo. The specific retention period for technical logs and the Google Analytics property retention settings must be verified and published before this page is put into production.
Your rights
Where the GDPR applies, you can request access to, correction or deletion of your data, portability where applicable, restriction of or objection to processing, and you can withdraw consent at any time. You can lodge a complaint with the CNIL in France. To exercise your rights, use the privacy contact shown above.
