Who is responsible for your data

The data controller is SIGMAJUNCTION DOO, Bačka Topola, Serbia - registration number (MB) 22134272, tax ID (PIB) 115257951.

What we collect

When you contact us we collect what you send: your name, work email, company and message. Alongside it we record how you reached us - the page you first landed on, the referring site and any campaign tags in the link - so we know what brings enquiries in; nothing is stored in your browser for this. Our website does not use advertising trackers or sell data to third parties.

Analytics

We use Google Analytics and Microsoft Clarity to understand how the site is used - but only if you explicitly allow it via the consent banner. Clarity shows aggregated heatmaps and recordings of how pages are scrolled and clicked; form fields are masked, so what you type is not captured. If you decline (or ignore the banner), neither loads and no analytics cookies are set. IP addresses are anonymised. Separately, we count page views with Cloudflare Web Analytics and with Umami, which we host ourselves; Umami also counts key actions, such as a click on a contact link or a sent form. Neither sets cookies or identifies you. You can change your choice by clearing this site's data in your browser.

How we use it

To respond to your enquiry, schedule calls, and - only if you become a client - to administer the engagement. We do not add you to mailing lists without explicit consent.

Where it lives

Enquiry data is stored in our email and CRM systems, hosted within the EU where available. Access is limited to the partners handling your enquiry.

If you subscribe to our newsletter we store your email address with Resend, our email provider, and only after you confirm the subscription by clicking the link we send you (double opt-in). We use it solely to send the newsletter - one or two emails a month. Every email contains an unsubscribe link; unsubscribing removes you from the list immediately. If you download one of our resources, we use your email address only to send you the download link, and we see who requested it. You join the newsletter only if you tick the box.

Your rights

Under GDPR you may request access to, correction of, or deletion of your personal data at any time. Write to hello@sigmajunction.com and we will respond within 30 days.

Client data in engagements

Data processed during engagements is governed by a separate data processing agreement signed per engagement - including confidentiality, retention and deletion terms.
