We collect the information you send through our contact form: your name, email address, phone number, company (if you provide it), the subject you choose, and your message. We also process IP address, browser User-Agent, and submission time to operate the site, respond to your request, and reduce abuse. If notification is configured, your message is forwarded to our email and Telegram providers so our team can respond. This site sets no analytics or advertising cookies: the only cookie is a session cookie, set only on the contact page to protect the form and time your submission, and it expires with your session. The hero font is served from this site itself, so no third-party font request is made. The only optional third-party service is Cloudflare Turnstile, which connects your browser to Cloudflare only when bot protection is switched on. We do not sell personal information. We keep submissions for as long as needed to respond, keep relevant business records, and meet applicable obligations. We publish no postal address or telephone number; our only contact channel is the email below. For questions or deletion requests, contact info@defender-sys.com.
