Corvers Survey - Terms of Service

Terms of Service

Last updated: 14 September 2026

These Terms of Service govern the use of Corvers Survey (the "Service"), the survey platform operated by Corvers for the creation, publication and analysis of online questionnaires and consultations. The Service is based on the EUSurvey open-source software published by the European Union and has been modified by Corvers.

1. Who may use the Service

The Service is provided to Corvers staff, to organisations participating in projects managed by Corvers, and to persons invited by Corvers. Registration requires a valid e-mail address and, where applicable, the validation of that address. Corvers may refuse, suspend or withdraw access where the Service is misused or where continued access would breach a legal obligation.

2. Accounts

You are responsible for the confidentiality of your credentials and for all activity carried out under your account. Credentials must not be shared. You must notify Corvers promptly if you believe your account has been compromised.

3. Acceptable use

You must not use the Service to publish unlawful content, to collect data by deception, to send unsolicited bulk messages, to attempt to gain unauthorised access to the Service or to the data of other users, or in any way that disrupts the availability of the Service for others. Automated scraping or bulk downloading of results is not permitted without written agreement.

4. Your content

You keep all rights in the surveys, questions, texts, files and answers you create or upload. You grant Corvers the rights strictly necessary to host, process, back up and display that content in order to operate the Service. You are responsible for ensuring that you have a lawful basis to collect the personal data requested by your questionnaires.

5. Personal data

The processing of personal data through the Service is described in the Privacy Statement and, for organisations acting as controllers, the Data Processing Agreement.

6. Availability and changes

The Service is offered on a best-effort basis. Corvers may modify, suspend or withdraw features, and may schedule maintenance, notably to apply security updates. Corvers will give reasonable notice of changes that materially affect users.

7. Intellectual property and open source

The Service's software is based on EUSurvey, © European Union, made available under the European Union Public Licence v1.2 (EUPL), and modified by Corvers from 14 September 2026. The software remains licensed to you under the EUPL v1.2; these Terms govern your use of the hosted Service and do not restrict the rights granted to you by that licence. The names "European Union", "European Commission" and "EUSurvey" are used solely to identify the origin of the software and do not imply any endorsement by the European Union or the European Commission.

8. Warranties and liability

The Service is provided "as is". To the extent permitted by law, Corvers excludes implied warranties and is not liable for indirect or consequential loss, or for loss of data arising from circumstances outside its reasonable control. Nothing in these Terms limits liability that cannot lawfully be limited.

9. Applicable law

These Terms are governed by the law applicable to Corvers Commercial & Legal Affairs, without prejudice to mandatory consumer or data-protection provisions.
