2. Definitions
| Platform | The EGG Science online software (SaaS), available on the web or as an app, used to run assessments and manage their results. |
| Services | Individual and team assessments with personalised reports, the management platform (invitations, teams, respondents, results), and the training, certification and support included in the subscribed plan. |
| Plan | The subscription option chosen (Free, Essential, Full or Corporate), as described on the website’s Plans page. |
| User | Any person who uses the Platform or subscribes to the Services through an account. |
| Respondent | Any person invited by a User to complete an assessment. |
| Certification | The training and evaluation that enable the User to master an assessment before applying it to others. |
3. Acceptance of the Terms
Subscribing to a Plan or creating an account requires express acceptance of these Terms at the time of ordering. The Terms that apply are those in force on the date of subscription.
The paid Services are mainly intended for professionals (coaches, consultants, HR professionals, companies). Users must be of legal age and have the legal capacity to enter into a contract. If you act as a consumer, you also benefit from the rights granted to you by law, as set out in section 7.
4. Plans, prices and payment
The content and prices of each Plan are shown on the website’s Plans page, in the currency for your region. Applicable taxes are shown before you confirm payment.
Payment is made online through our secure payment providers (Stripe for payments in euros and US dollars). Annual Plans are billed once for twelve months; monthly Plans are billed every month. Access to the Services is granted as soon as payment is confirmed.
EGG Science may change its prices. Any change applies only to new subscriptions or to the next renewal, after informing the User at least 30 days in advance.
In the event of non-payment, access to the Services may be suspended until payment is made, after a reminder has gone unanswered.
5. Term, renewal and termination
Monthly Plans: the subscription renews every month. It can be cancelled at any time; cancellation takes effect at the end of the current monthly period.
Annual Plans: the subscription runs for twelve months and renews for a further twelve months unless cancelled at least 30 days before its end date. EGG Science reminds you by email before each renewal. The price of a started year remains due, subject to section 6.
Cancellation requests are sent by email to legal@eggscience.com.
EGG Science may suspend or terminate a User’s access in the event of a serious breach of these Terms (in particular sharing login details, fraudulent or unlawful use), after a formal notice that has gone unremedied for 8 days, except in urgent cases.
6. Free cancellation within 15 days
On a first subscription to a paid Plan, you can cancel within 15 days of payment and receive a full refund, without giving any reason. The refund is made using the same payment method within 14 days of your request.
For training or certification sessions scheduled on a specific date, registration can be cancelled free of charge up to 24 hours before the session starts. If EGG Science cancels a session, the User may choose another date at no extra cost or receive a full refund.
7. Consumer rights
If you are a consumer in the European Union, you have a 14-day right of withdrawal from the date of subscription; the free cancellation in section 6 gives you a longer period. If you ask to access the Services before that period ends, you remain free to withdraw under the conditions provided by law.
In the event of a dispute, you may use a consumer mediation service free of charge after sending a written complaint to EGG Science. You may also use the European online dispute resolution platform.
8. Account and access
The Platform is accessed through a personal account (username and password) or, for Respondents, an individual link. Users must provide accurate, up-to-date information and keep their login details confidential: as the licence is personal, sharing them with anyone else is prohibited. If their account is used without authorisation, Users must change their password and inform EGG Science immediately.
Applying an assessment to others requires the corresponding Certification, included in the relevant Plans.
Using the Platform requires an internet connection and an up-to-date browser or device, at the User’s expense.
9. Licence
For the duration of the subscription, EGG Science grants the User a personal, non-exclusive and non-transferable right to use the Platform for their professional needs. The Platform is not sold: no ownership rights or access to the source code are transferred.
Copying, modifying, decompiling, reselling, sub-licensing or making the Platform available to unauthorised third parties, extracting data by automated means (bots, scraping) or compromising its security is prohibited.
10. Intellectual property
The assessments, methodologies, reports, content, trademarks (including Startrust, Voluntus, NeoSales and Helios), logos, texts, visuals and software are the exclusive property of EGG Science or its licensors. Any unauthorised reproduction or use is prohibited.
Users may give their clients the reports generated for them as part of their services, without modifying them or removing the EGG Science notice.
11. Use of results
The assessments are tools to support personal and professional development. They are not a medical or psychological diagnosis, nor the sole basis for a decision about a person (hiring, sanction, dismissal). The User remains solely responsible for interpreting the results and for the decisions they make.
When inviting Respondents, the User undertakes to inform them of the purpose of the assessment and of how their data is processed, in accordance with applicable regulations.
12. User obligations
Users undertake to use the Services for their intended purpose, in accordance with these Terms and the law; not to share unlawful content or content that infringes the rights of others; not to introduce viruses or malicious code; and not to collect other Users’ data.
13. Availability and changes
EGG Science uses reasonable efforts to keep the Platform available 24/7, except during maintenance, updates or events beyond its control. It may change the Platform to improve it or to comply with regulations, without substantially reducing the essential features of the subscribed Plan during the subscription.
14. Liability
EGG Science has a best-efforts obligation. It is not liable for misuse of the Services, failures of the internet or of the User’s equipment, or force majeure.
Towards professional Users, EGG Science’s liability is limited to direct and foreseeable damage and capped at the amount paid by the User in the twelve months preceding the event giving rise to the claim. These limitations do not apply in the event of gross negligence or wilful misconduct, to personal injury, or to rights guaranteed to consumers by law.
15. Personal data
The processing of personal data is described in our Privacy Policy. Marketing communications are only sent with your consent or, for our customers, about services similar to those subscribed, with the option to object at any time.
16. Changes to the Terms
EGG Science may change these Terms. Subscribed Users are informed by email at least 30 days before any substantial change takes effect; if they do not accept it, they may cancel their subscription free of charge before that date.
17. Governing law and disputes
These Terms are governed by French law. In the event of a dispute, the parties will first seek an amicable solution. Failing that, for professional Users, the courts of Paris have exclusive jurisdiction. Consumers may bring proceedings before the courts of their place of residence or any other court with jurisdiction under applicable law.
