Email-based enquiries
The current website enquiry form prepares a draft in your own email application. The website does not submit or store the form contents. SIDERA receives the information only after you choose to send the email.
Information you provide
Your message may include your name, company, business email, country, product requirements and project information. SIDERA uses that information to respond to the enquiry and evaluate the requested product or project scope.
Do not include sensitive information
Do not include passwords, payment-card data, personal identity documents, controlled technical data or other sensitive information in the initial enquiry.
