Zenrez

MarketingOfficial website

Zenrez is a US based marketing platform for fitness and wellness studios. It markets unsold class spots, drives bookings through paid channels and uses a JavaScript pixel on partner studio sites to track funnel performance. For European studios using Zenrez, the platform raises GDPR and ePrivacy obligations on cookies, consent, profiling of class attendees and transfer of personal data to the United States.

Overview

What does Zenrez do?

What Zenrez is and how it works

Zenrez is a US marketing platform dedicated to fitness, yoga, pilates, hiit and wellness studios. It fills empty class spots through paid acquisition on Meta, Google and TikTok, runs retargeting on past attendees, and powers landing pages and offers. Its JavaScript pixel sits on partner studio websites and captures booking funnel events that are matched with Zenrez's marketplace and ad inventory.

What data Zenrez collects

IP address, user agent, click identifiers, UTM parameters, attendee email and phone provided at booking, hashed identifiers for advertising matching, class identifier, studio identifier, time slot, attendance status and conversion value. Behavioural cookies persist across visits to follow the booking journey.

GDPR and ePrivacy implications

The Zenrez pixel sets non strictly necessary cookies and shares data with a third party for advertising. Article 5(3) ePrivacy requires prior consent. Class attendance data can imply health context (prenatal yoga, rehabilitation pilates), which raises the sensitivity bar and reinforces the need for transparent information and minimisation.

Consent requirements

Capture explicit consent for the Zenrez pixel as advertising tracking. Do not combine it with other purposes. Allow the user to reject as easily as accept. Process attendance data only on a clear lawful basis (performance of contract for the booking itself, consent for marketing).

International data transfers

Zenrez infrastructure is in the United States. EU attendee data is transferred to the US. Transfers must rely on SCCs, on the EU US Data Privacy Framework where Zenrez is certified, and on supplementary measures such as encryption and minimisation.

Practical compliance steps

Sign a DPA, document the US transfer, gate the Zenrez pixel behind consent, separate marketing from booking purposes in the privacy notice, set short retention on attendance data, run a DPIA where wellness data implies health context, and audit the data fields actually shared with Zenrez.

Compliance

Zenrez and the GDPR

Zenrez is classified as “Marketing”. On a site that targets European visitors, it must only load after the visitor consents, and it must be listed in your cookie policy.

Legal basis
Zenrez writes cookies and forwards identifiers to a third party for marketing purposes. Article 5(3) ePrivacy and the GDPR require prior consent before the Zenrez pixel fires on an EU studio website.
Risk level
high
Applicable regulations
GDPR, ePrivacy Directive, national cookie laws, EU US Data Privacy Framework.

Impact assessment (DPIA)

A DPIA is recommended when Zenrez processes EU attendee data at scale. Wellness data, while not strictly health data, often hints at health context (yoga vs hiit, prenatal classes). Document this sensitivity, retention, US transfers and the consent flow.

Does Zenrez require user consent?

What is the legal basis for Zenrez?

Marketing pixel: consent under article 6(1)(a) GDPR and article 5(3) ePrivacy. Booking processing itself: performance of contract under article 6(1)(b) GDPR. Profiling for retargeting: consent. Sensitive class types: never use as advertising segment without explicit consent.

Does Zenrez transfer data to the US?

Yes. Zenrez is a US company with US infrastructure. Attendee data is transferred to the US. Transfers rely on SCCs, the EU US Data Privacy Framework if Zenrez is certified, and supplementary measures such as encryption and access controls.

How do we implement Zenrez compliantly?

Sign a DPA, gate the Zenrez pixel behind a Consent Management Platform, minimise the personal data sent (do not include sensitive class types in marketing segments), short retention, document everything, restrict access and review the integration regularly.
