Opentracker

Analytics

Opentracker is a real time web analytics service based in Amsterdam that shows individual visitor activity, clicks, sources and ecommerce events as they happen. It uses first party cookies to recognise visitors and sessions, so it can follow a visitor through a site in real time. Because it tracks identifiable visit behaviour it needs consent for its cookies, but as a Netherlands based provider it keeps data in the European Union, which removes the third country transfer concern.

Overview

What does Opentracker do?

What Opentracker is

Opentracker is a web analytics platform from the Netherlands that focuses on real time, visitor level reporting. Rather than only aggregated charts, it shows the live activity of individual visitors, their navigation paths, sources and ecommerce actions. A JavaScript snippet collects the events and a dashboard presents them in real time, which is useful for understanding behaviour as it happens.

What data and cookies Opentracker processes

Opentracker sets first party cookies that store a visitor identifier and session information so it can recognise a returning visitor and stitch a session together. It records page views, clicks, referrers, search terms, device data and, for online stores, ecommerce events. Because it tracks at the level of an individual visitor rather than only in aggregate, the data is personal data even though it does not require a name.

GDPR and ePrivacy implications

The cookies Opentracker uses to recognise visitors are analytics trackers, not strictly necessary, so they require prior consent under article 5(3) of the ePrivacy Directive, with consent as the legal basis under GDPR article 6(1)(a). Visitor level analytics is harder to justify on legitimate interest than aggregated, anonymised measurement, so keep the tag blocked until the visitor accepts analytics cookies and consider whether you need visitor level detail.

Data location and transfers

Opentracker is operated from Amsterdam and processes and stores data in the European Union, so there is no transfer of personal data to a third country and no need for the EU US Data Privacy Framework or standard contractual clauses. Keeping the analytics in the EU is a meaningful advantage over United States based tools and simplifies your records of processing.

Practical compliance steps

Gate the Opentracker tag behind analytics consent and confirm with developer tools that no Opentracker cookie is set before consent. Sign a data processing agreement, set a sensible retention for the visitor level data, and describe Opentracker, its EU hosting and the cookies in your privacy and cookie policies. Consider whether aggregated reporting would meet your needs with less personal data.

Impact assessment (DPIA)

Opentracker provides visitor level, real time analytics, which is more privacy intrusive than aggregated measurement, so assess whether a DPIA is needed, especially at scale. The data stays in the European Union, which keeps the transfer risk low, but document the visitor level processing, the retention, the data processing agreement and the consent gating.

Questions

Frequently asked questions about Opentracker

Can't find your question? Write to us, we answer fast.

Which cookies does Opentracker set?

Opentracker sets first party cookies that store a visitor identifier and session information, so it can recognise a returning visitor and reconstruct a session. They are analytics cookies, not strictly necessary ones, and they require consent because they track at the level of an individual visitor.

Do I need consent to use Opentracker?

Yes. The cookies Opentracker uses to recognise visitors are analytics trackers, so they require prior consent under article 5(3) of the ePrivacy Directive. Keep the tag blocked until the visitor accepts analytics cookies.

What is the legal basis?

The analytics cookies rely on consent under GDPR article 6(1)(a) and ePrivacy article 5(3). Visitor level, real time analytics is harder to base on legitimate interest than aggregated, anonymised measurement, so consent is the safer basis.

Does Opentracker transfer data to the United States?

No. Opentracker is operated from Amsterdam and stores data in the European Union, so there is no transfer of personal data to a third country and no need for the EU US Data Privacy Framework or standard contractual clauses.

Do I need a DPIA?

Possibly, because visitor level real time tracking is more intrusive than aggregated analytics. Assess the processing, the retention and the scale. The EU hosting keeps the transfer risk low, which reduces the overall risk.

How do I implement Opentracker compliantly?

Gate the tag behind analytics consent, confirm no cookie is set before consent, sign a data processing agreement, set a sensible retention for the visitor data, and describe Opentracker and its EU hosting in your privacy and cookie policies.

What are the alternatives to Opentracker?

Other EU friendly analytics include Matomo, Plausible, Fathom and SealMetrics, several of which can run cookieless and consent free. If you do not need visitor level real time detail, an aggregated, cookieless tool reduces both the consent burden and the privacy risk.

How do I keep my cookie policy up to date with Opentracker?

List Opentracker, its visitor and session cookies, their purpose and the EU hosting in your cookie policy, and review it when you change the tracking configuration or retention. Keep the consent categories aligned with the visitor level analytics.
