When creating its Owner Account, the Client chooses both the Resources and the Collaborator’s Role, as set out in Appendix 1. The Client may appoint an “admin” to invite Collaborators and choose their Role.

4. Term

4.1. Free tier

The Client subscribes to a Free tier for an indefinite period of time. The Client may at any time upgrade his/her subscription by selecting a paid tier and paying the applicable Fee.

4.2. Paid tiers

The Client subscribes to a paid tier for a determined period of time, either for one (1) month or one (1) year (the “Term”). Unless the Client cancels the subscription before the end of the Term through the Platform’s account management interface, the subscription shall automatically renew for a successive Term of the same duration, and the applicable Fee shall be charged according to the payment method registered by the Client.

If the Client cancels the subscription before the end of the Term, the subscription shall remain active until the end of the current Term and shall not renew.

Failing to comply with these Terms of Use, with the Student tier eligibility criteria above-mentioned, or with the non-commercial use restriction, Rayon shall downgrade the Client’s Student account to a Free tier account. As a result, the Client shall no longer have access to some of the Platform’s paid tier features.

4.6. Trial Period

Rayon may, at its sole discretion and at any time, offer a free trial period (“Trial”) in any given country. The availability of the Trial depends on the geographic location inferred from the User’s IP address. Rayon does not warrant the accuracy of the geographic determination, and the User acknowledges that access to the Trial may vary accordingly.

Where a Trial is available, the following terms shall apply:

  • The Trial duration is set to a fixed period defined at the sole discretion of Rayon.

  • The Trial grants the User temporary access to a set of features determined at the discretion of Rayon.

  • The Trial shall begin automatically upon (i) the User’s first creation of an Owner Account, or (ii) the User’s first sign-in after the Trial has been enabled in the User’s country.

  • The User may upgrade to any paid tier at any moment during the Trial.

  • At the expiration of the Trial, the User shall automatically revert to the plan corresponding to their current subscription, or to the Free tier if no paid subscription has been purchased.

  • At the end of the Trial, the User shall lose access to any functionality not included in their current plan. In particular, Users on the Free tier will no longer be able to edit private Models, which is a feature exclusive to the Pro and Team tiers.

  • Private Models that were editable during the Trial will become read-only for Users on the Free tier. To regain edit access, such Models must be manually converted by the User to Public status. A Public Model may be searched, viewed, and copied by any Rayon User, but may only be edited by its owner or by collaborators who have been granted editor rights.

Rayon reserves the right to modify, suspend, or discontinue the Trial offering at any time and without prior notice, without giving rise to any compensation for the User.
