Terms of use

Last updated: 13 November 2026.

These terms cover the use of the Quantilo website and of its web version (quantilo.cyrilkfouri.com). The software itself (app, Docker image, Python library, source code) is governed by its licence, the MIT licence: you may use, copy, modify and redistribute it freely, keeping the copyright notice.

1. A free tool, provided as is

Quantilo is free, open-source software written and published by a private individual, without payment and outside any commercial activity. It is provided "as is", without warranty of any kind, express or implied, including fitness for a particular purpose, accuracy of the results or availability of the site.

Statistical results, forecasts, models and AI answers can be wrong or misleading, especially on small, biased or badly typed data. Check them before you rely on them. Quantilo is not financial, medical, legal or any other professional advice.

2. Liability

To the extent permitted by law, the publisher is not liable for any damage resulting from the use of, or the inability to use, Quantilo or the site: in particular loss of data, loss of profit, or decisions taken on the basis of its results.

Nothing in these terms excludes or limits a liability that the law does not allow to exclude or limit, such as liability for gross negligence or intentional misconduct, or the rights you have as a consumer under the mandatory law of the country where you live.

3. Your data

• You keep every right to the data you analyse. It stays on your device (see Privacy); the publisher never receives it.
• You must have the right to process it. If it contains personal data about other people, you are responsible for that processing under the GDPR or the law that applies to you.
• Keep a copy of your files: the browser can clear its storage, for example when space runs low.

4. Acceptable use

• Do not try to break, overload or get around the security of the site or of the services it uses (scanning, flooding, injecting code).
• Do not use Quantilo to process data you are not allowed to hold, or for any illegal purpose.
• Do not present the Quantilo name or logo in a way that suggests the publisher endorses your work or product.

Found a security issue? Please report it privately through a GitHub security advisory rather than in public.

5. The AI assistant

In the app on your computer, the optional assistant uses your own API key with the provider you choose. That provider's terms and prices apply, and its costs are yours. Do not send it data you are not allowed to share (see Privacy).

6. Third-party services

The site is hosted by Vercel and loads Python and its libraries from jsDelivr; the code is published on GitHub. Signing in with Google is optional: the web version works fully as a guest, and an account gives no extra right for now. If you sign in, Google's terms apply to your Google account. Each of these services has its own terms. Links to other sites are given for convenience; the publisher does not control them.

7. Changes and availability

The site and the software can change, or stop, at any time and without notice. These terms can change too: the date above says when, and the public history on GitHub keeps every version.

8. Law and disputes

These terms are governed by French law. If you are a consumer, you also keep the protection of the mandatory rules of the country where you live, and you can go to the courts there. Before any dispute, please write to the publisher (see the Legal notice): most problems are solved that way.
