Privacy Policy
Last updated: 1 June 2026
Introduction
Cyntheion (“we”, “our”, “us”) is committed to protecting and respecting your privacy. This policy explains how we collect, use, disclose and retain personal data when you visit cyntheion.com or contact us.
Data we collect
We collect the personal data you provide to us directly, for example your name, email, company, phone number and any message you include when you complete a contact or subscribe form. We also automatically collect non-identifying information such as browser, device and usage data.
How we use your data
We use personal data to respond to enquiries, provide services, send marketing where permitted, and to improve our website and services. Where required by law (for example under the GDPR), we process data on a lawful basis such as consent, contract performance, or our legitimate interests (for example, to operate and secure the website).
Cookies and tracking
We use cookies, including third-party cookies (e.g. HubSpot), to personalise the site, analyse traffic, and deliver forms and marketing. When we submit forms to HubSpot we may include the HubSpot tracking cookie (hubspotutk) in the submission context so that HubSpot can connect form submissions to existing contacts.
Marketing and consent
Where you opt in to receive communications, we will only send marketing messages in accordance with your preferences. For HubSpot-powered forms we capture explicit legal consent fields (consentToProcess and communications) so that opt-ins are recorded and auditable.
Sharing and third parties
We may share data with service providers who process data on our behalf (for example HubSpot for forms and email). We require providers to follow appropriate security and privacy practices.
Data retention
We retain personal data only as long as necessary to fulfil the purposes described here, or as required by law. You can request deletion at any time (see Rights below).
Your rights
Depending on your jurisdiction you may have rights including access to the data we hold about you, correction, deletion, restriction of processing, portability, and the right to object to processing. To exercise your rights please contact us using the details below.

For questions about this policy or to exercise your rights, contact us via our contact page or email info@cyntheion.com.
Changes to this policy
We may update this policy from time to time. We will publish changes on this page with a revised effective date.
