Data controller and contact
The data controller is the Cercle d’Études Scientifiques Pierre Rayer. Questions concerning personal data and requests to exercise your rights may be submitted through the contact form or sent to [email protected].
Information collected
When you use the contact form, the CESR may collect your name, email address, organisation, subject and message. Technical data necessary for site security and operation, such as an IP address, browser information and security logs, may also be processed.
Purposes and legal bases
- Responding to enquiries, proposed partnerships and research requests.
- Managing institutional, scientific and cultural relations.
- Protecting the website against spam, abuse and security incidents.
- Meeting applicable legal and administrative obligations.
Processing is based, depending on the circumstances, on your request or consent, the CESR’s legitimate interest in responding and protecting its website, or a legal obligation.
Recipients and transfers
Personal information is accessible only to persons authorised to process the request and to service providers strictly necessary for hosting, security, maintenance or email delivery. The CESR does not sell personal data. Links to external websites are governed by the privacy practices of those websites.
Retention
Contact correspondence is retained only for the period necessary to respond and follow the relevant relationship, normally no longer than three years after the last meaningful exchange, unless a longer period is required by law, by a contractual relationship or for the establishment, exercise or defence of legal claims. Security logs may be retained for shorter technical periods.
Cookies
The website may use cookies or comparable technical storage necessary for administration, security, display preferences, caching and normal operation. Additional measurement or third-party cookies, if activated, must be disclosed and managed in accordance with applicable consent requirements.
Your rights
Subject to applicable law, you may request access to, correction or deletion of your data, restriction of processing, portability where applicable, or object to processing based on legitimate interests. You may also withdraw consent without affecting processing carried out before withdrawal and lodge a complaint with the competent data-protection authority.
Security and confidential documents
Reasonable technical and organisational measures are used to protect the website and submitted information. No internet transmission is entirely risk-free. Please do not send confidential documents before the scope and conditions of their examination have been agreed with the CESR.
