Cookie Policy.
We minimize the use of cookies and similar technologies. We do not run third-party advertising, no marketing pixels, no cross-site tracking. This page lists every cookie used on the marketing site and the choices available to you.
1. About Cookies
A cookie is a small text file stored on your device when you visit a website. Cookies are commonly used to remember preferences, secure sessions, or analyze traffic. Some are set by us ("first-party") and some by services we use ("third-party").
2. Cookies We Use
Strictly necessary — first-party. sdCookieOk (localStorage, not technically a cookie) records that you have dismissed the cookie notice. Persistence: until cleared by you. Purpose: prevent the banner reappearing on each visit.
Strictly necessary — security (third-party). Google reCAPTCHA sets cookies and reads device signals when you submit our contact or request-a-conversation form, in order to distinguish humans from automated abuse. These are essential to the security of the form and are governed by Google's Privacy Policy and Terms of Service.
3. Cookies We Do Not Use
We do not set advertising or marketing cookies, cross-site identifiers, behavioral profiling cookies, or remarketing pixels (Meta Pixel, LinkedIn Insight, X / Twitter Pixel, Google Ads, TikTok Pixel — none).
We do not run general-purpose third-party web analytics (Google Analytics, Adobe, Mixpanel, Plausible, etc.) on the marketing site. Server-side access logs (described in our Privacy Notice) are used for security and reliability only.
4. Legal Basis (EU/UK)
Strictly-necessary cookies do not require consent under the ePrivacy Directive or the UK PECR. We rely on our legitimate interest in operating the site securely (UK/EU GDPR Art. 6(1)(f)).
Because we do not set non-essential cookies, no consent dialog is presented — the banner on the site is informational only.
5. Your Choices
Browser settings. All modern browsers let you block or clear cookies and localStorage. Doing so will not break the site — at most, the cookie banner will reappear.
Do Not Track. We respect Global Privacy Control (GPC) signals where supported by our infrastructure. Because we do not engage in cross-context behavioral advertising, GPC has no further effect on our processing.
Submission deletion. If you previously submitted a form and would like the record deleted, email privacy@seifertdynamics.com.
6. Updates
We update this policy when we add or remove cookies. Material changes are flagged at the top of this page.
