Terms of use

1. Definitions

“Publisher” means KAYZEN, identified in the legal notice. “Site” means the public Kayzen Security website. “Service” means the Kayzen Home service, including the simplified console, the protection apps and the related cloud services. “User” means any person who browses the Site or uses the Service. “Account Holder” means the adult who creates a family account.

2. Acceptance

Browsing the Site implies acceptance of the part of these terms that concerns it. Creating a family account requires express acceptance of these terms and acknowledgement of the privacy policy, recorded by checkboxes at sign-up.

3. Use of the Site

The Site is free to access, subject to the User's own connection costs. The Publisher may suspend access for maintenance, security or force majeure.

It is forbidden to interfere with the operation of the Site, to attempt to access non-public areas other than under the responsible disclosure policy, or to extract its content on a large scale for commercial purposes without permission.

4. The Kayzen Home service

Kayzen Home is a protection service for the devices in a household: filtering of dangerous websites, parental controls, software updates and, as they are delivered, antivirus and ransomware protection. The Service is under development: modules are being made available gradually, depending on the operating system.

On iPhone and iPad, the Service is limited to web, DNS and SMS protection. It is not an antivirus, because iOS does not allow the scanning of files belonging to other apps.

5. Free of charge and the Publisher's commitments

The Service is provided free of charge, with no time limit, with no payment method requested and with no monetary or data-based consideration. The Publisher undertakes, for the Service:

• to show no advertising, in the apps, the console or emails;
• not to sell, rent or monetise any User data, and not to use it for ad targeting or to train artificial intelligence models;
• not to remove or limit any protection feature of the Service in order to push you to subscribe to a paid plan.

“Free for life” means that the Service remains free for as long as the Publisher operates it: an existing family account will never be converted into a paid subscription, and neither advertising nor data monetization will be introduced. If the Publisher were to shut down the Service, it would inform Account Holders by email at least six months in advance and allow them to export their data. [À VALIDER]

6. Private use and limits

The Service is reserved for the private, non-commercial use of one household. Use by a company, an employer association or a professional for their business is excluded; such users fall under the business offers.

A family account covers up to 10 devices. To prevent abuse and to keep the infrastructure costs borne by the Publisher under control, reasonable technical limits may apply (number of profiles, tokens, requests).

7. Account and security

The Account Holder must be of legal age, provide a valid email address that they verify, and enable two-factor authentication. They are responsible for keeping their sign-in credentials confidential and for the profiles they create, in particular for minors in their care.

Parental controls must be used in the child's best interests and with respect for their privacy; the app is visible on the protected device.

8. User obligations

• not to circumvent, decompile or alter the apps, except where permitted by law;
• not to use the Service to monitor a person without their knowledge;
• not to use the Service's DNS resolver as a public resolver or for third parties outside the household;
• to report any vulnerability in accordance with the responsible disclosure policy.

9. Availability and liability

The Publisher uses reasonable endeavours to ensure the availability and effectiveness of the Service, under an obligation of means. No security solution can guarantee absolute protection: the User keeps backups of their data and applies updates to their devices.

To the extent permitted by law, the Publisher cannot be held liable for indirect damage; nothing in these terms limits the rights that consumers hold under mandatory provisions. [À VALIDER]

10. Suspension and termination

The Account Holder may delete their account at any time from the console; their data is then erased within the periods stated in the privacy policy.

The Publisher may suspend an account in the event of a serious breach of these terms (commercial use, abuse, breach of security), after informing the Account Holder except in urgent cases. Accounts with no active device for an extended period may be deleted after prior notice to the Account Holder; this period is yet to be set. [À VALIDER]

11. Changes to the terms

The Publisher may amend these Terms of Use. Account Holders are informed by email of any substantial change at least 30 days before it takes effect; they may delete their account if they refuse it. These changes may neither make the Service paid nor call into question the commitments of article 5.

12. Governing law and disputes

These Terms of Use are governed by French law. In the event of a dispute, the consumer User first sends a written complaint to the Publisher. Failing a solution within 60 days, the User may refer the matter free of charge to the consumer mediator [À VALIDER: name, address and website of the mediator to be appointed], and then to the competent court under ordinary-law rules.
