Privacy Policy

1. Preamble

At Zylior, the protection of your personal data is a priority. This privacy policy describes how we collect, use, share and protect the personal data of users of our growth-management platform (hereinafter "the Service"), in accordance with Regulation (EU) 2016/679 of 27 April 2016 ("GDPR") and, where applicable, the national data-protection laws applicable within the European Economic Area.

It applies to anyone who visits our site, creates an account, uses the Service or interacts with us. By using Zylior, you acknowledge that you have read this policy. We encourage you to read it carefully and to consult it regularly, with its last update indicated at the bottom of the page.

2. Data controller

The controller of the data collected via the Service is:

As Levelthree saas-system LLC is established outside the European Union, any request relating to your data or to the exercise of your rights may be addressed directly to the data controller at legal@zylior.com.

For the data that you yourself enter into Zylior concerning your own prospects, customers or contacts, Zylior acts as a processor within the meaning of the GDPR: you remain the controller of that data, under the data processing agreement (DPA) that supplements our Terms and Conditions.

3. Data we collect

We collect only the data necessary for the proper functioning of the Service and the business relationship. Depending on your use, this includes:

3.1 Account and identification data

3.2 Billing data

3.3 Usage and technical data

3.4 Data you import into the Service

We do not knowingly collect so-called "sensitive" data (origin, opinions, health, etc.). We ask you not to include any in the Service.

4. Purposes and legal bases

Each processing operation relies on a specific legal basis within the meaning of Article 6 of the GDPR:

Where processing relies on your consent, you may withdraw it at any time, without affecting the lawfulness of prior processing.

5. Recipients and processors

Your data is never sold. It is accessible only to authorized Zylior personnel and to carefully selected processors, acting on our instructions and bound by confidentiality and security obligations. They operate across the following categories of services:

Each processor is governed by a contract compliant with Article 28 of the GDPR. The named list of our processors is available on simple request to legal@zylior.com. We may also disclose data where required by law (judicial or administrative authority) or to protect our rights and the security of the Service.

6. Transfers outside the European Union

The application is hosted within the European Union. However, the publisher (Levelthree saas-system LLC) is established in the United States, and some of our processors process data there. These processing activities therefore involve a transfer of data to a third country (the United States).

For these transfers, we rely on appropriate safeguards within the meaning of Chapter V of the GDPR:

supplemented, where necessary, by additional measures. You can write to us at legal@zylior.com to obtain a copy or the details of the safeguards put in place.

7. Retention periods

We retain your data only for as long as necessary for the purposes pursued, after which we delete or anonymize it:

Billing and accounting data10 years (legal obligations)
Prospects and marketing data3 years from the last contact

8. Your rights

In accordance with the GDPR, you have the following rights over your personal data:

To exercise these rights, write to us at legal@zylior.com. We may ask you for proof of identity, and we will respond within one month. If you believe your rights are not being respected, you may lodge a complaint with the French Data Protection Authority (CNIL), 3 Place de Fontenoy, TSA 80715, 75334 Paris Cedex 07 — www.cnil.fr.

9. Cookies and trackers

Our site and our application use cookies and similar technologies to function, measure audience and improve your experience. We distinguish between:

First-party tracking pixel

With your consent ("Accept all" banner), our pixel sets a random identifier (stored in your browser's localStorage) and collects: page views, sessions, scroll depth, time on page, viewing of pricing pages, and your email address if you provide it (sign-up, form). Purpose: to create a visitor profile in our CRM, calculate a purchase-intent score for prospecting purposes, and match this profile to your account upon sign-up. Sites concerned: zylior.com and, where applicable, other sites of the same publisher (disclosed on request). Anonymous profiles are deleted after 13 months of inactivity. You can withdraw your consent at any time via the "Cookies" link in the footer (the identifier is then deleted) or request the erasure of the profile at legal@zylior.com.

Audience measurement and conversational assistant

Our audience measurement relies on a cookieless, self-hosted solution: the script is only loaded and activated after your consent ("Accept all" banner). The conversational assistant (chat widget "powered by Zylior") loads to allow you to write to us; it only records a conversation identifier when you actually start an exchange, and the content you enter there is transmitted to our artificial intelligence provider (processor) in order to generate a response. No non-essential tracker (audience measurement, tracking pixel) is set or activated before your consent.

Non-essential cookies are only set after your consent, collected via our dedicated banner. You can change your choices at any time from the preference manager ("Cookies" link in the footer) or your browser settings. Refusing certain cookies may limit access to some features.

10. Data security

We implement appropriate technical and organizational measures to protect your data against any unauthorized access, loss, alteration, or disclosure, in particular:

In the event of a data breach likely to result in a risk to your rights and freedoms, we will notify the CNIL and, where applicable, the individuals concerned, under the conditions provided for by the GDPR.

11. Data and artificial intelligence

Zylior relies on artificial intelligence models to generate content, qualify leads, and automate actions. The data you provide for these features is processed for the sole purpose of delivering the requested service. We select AI vendors that do not use your data to train their models without an appropriate legal basis, and we govern these processing operations contractually.

12. Minors

The Service is intended exclusively for professional use by adults. We do not knowingly collect data concerning minors. If you believe a minor has provided us with data, contact us so that we can delete it.

13. Changes to the policy

We may update this privacy policy to reflect legal, technical, or organizational changes. Any substantial change will be notified to you by email or through the Service. The applicable version is the one published on this page, the date of last update of which appears below.

14. Contact

For any question relating to this policy or to the protection of your data, or to exercise your rights, contact the data controller:
