Data controller
Tristan Baud, an independent professional operating under the name Lexen, is responsible for the processing described on this page. For any question or request concerning your data, contact hello@lexen.agency.
Data processed and purposes
- Website access: the technical infrastructure may process your IP address, date and time, requested resource, browser, device and referrer to deliver and secure the website.
- Email contact: your address, any name you provide and the content of the exchange are used to answer your request and, where relevant, prepare a contractual relationship.
- Contact form: your name, email address, company website if provided, chosen topic and message are sent through the Web3Forms service, which forwards them to us by email so we can answer your request.
- Appointment booking: when you choose to display Google Calendar or open the booking page, Google processes the necessary technical data and the information you enter.
- Audience measurement: Google Analytics collects information about your visit (pages viewed, duration, referrer, device and browser type, approximate location) so we can understand how the website is used and improve it. Lexen uses these statistics only to measure audience, not for advertising.
Cookies and analytics
This website uses Google Analytics, an audience measurement tool provided by Google. It sets cookies (notably _ga) that distinguish visits pseudonymously. The script only loads after your first interaction with the page, or a few seconds after it is displayed. Lexen uses no advertising pixels.
You can refuse these cookies in your browser settings or install the Google Analytics opt-out browser add-on. The font is hosted locally. Google Calendar is contacted only after you click “Choose a time”, “Book a 30-min call” or the booking link.
Recipients and service providers
Data may be accessible to providers strictly required for website hosting and security, email services, delivery of contact form messages (Web3Forms), audience measurement (Google Analytics) and, when you activate it, Google Calendar. Clicking LinkedIn or another external source takes you away from this website and makes the relevant service’s policy applicable.
International transfers
Some providers, including Google and Web3Forms, may process data outside Switzerland, including in the United States. These transfers rely on safeguards provided by the service provider and applicable law. Read the Google Privacy Policy.
Retention
Data is kept only for as long as necessary for the relevant purpose, then deleted or anonymised, subject to legal obligations. Business correspondence may be retained while it remains useful to the relationship. Google’s own retention periods depend on its settings and policies.
Your rights
Depending on the applicable law, you may request access to, correction, delivery or deletion of your data, or restriction of certain processing. You may also object where the law provides this right. Identity verification may be required.
Send requests to hello@lexen.agency or consult the Federal Data Protection and Information Commissioner.
Security and updates
Lexen applies proportionate technical and organisational measures to reduce unauthorised access, loss or alteration of data. This notice may be updated when the website, providers or legal requirements change.
