Uzerly

AnalyticsOfficial website

Uzerly is the retargeting platform of Cibleclic SAS, a Paris company founded in 2012. E-commerce sites install its tag to follow the products visitors view, add to basket or buy, then re-engage them through display retargeting, email remarketing, on-site messages and RCS. Because it stores an identifier in the browser and builds advertising profiles, it may only be loaded after the visitor has given marketing consent.

Overview

What does Uzerly do?

What is Uzerly?

Uzerly is a retargeting and remarketing platform published by Cibleclic SAS, a company registered in Paris and founded in 2012. It is sold to advertisers, mainly French e-commerce and travel brands, to bring back visitors who left without buying. Its offer covers display retargeting, email remarketing (messages sent to identified visitors who abandoned a basket), on-site remarketing (personalised overlays) and mobile remarketing through RCS messages. Uzerly is not a session replay or user testing tool.

How Uzerly appears on a website

The advertiser adds an "all pages" tag that injects a script from a dedicated subdomain such as 1234.userly.net/cl.js, the number being the advertiser's account. Additional tags describe product pages, basket pages and the order confirmation page (product IDs, prices, basket content, transaction ID), and the script sends these events to the Uzerly tracking endpoints. Technology scanners detect Uzerly through the userly.net script address or a uzerly.net or userly.net entry in the site's Content-Security-Policy header. Shopify stores may also run it as a custom pixel named "Uzerly Checkout".

Cookies and personal data

Cibleclic declares an identifier called us_dt, stored in the browser's web storage on the advertiser's domain, and states in the IAB Global Vendor List that its cookies last up to about six months. Data collected includes an online identifier, IP address, browser and device characteristics, pages and products viewed, basket and purchase events. For email remarketing, the visitor's browsing is linked to an email address.

GDPR and consent

Retargeting is a marketing purpose and is not strictly necessary for the site to work. Under Article 5(3) of the ePrivacy Directive and the GDPR, the tag must stay blocked until the visitor accepts marketing cookies. Cibleclic is registered as vendor 963 in the IAB Transparency and Consent Framework and relies only on consent, including for precise geolocation and device scanning features it declares. The tag servers observed are hosted in Germany.

Practical steps

  • Load every Uzerly tag (all pages, product, basket, transaction) only after marketing consent, through your consent platform or tag manager.
  • If you use a TCF banner, make sure vendor 963 (Cibleclic) is listed.
  • Mention Uzerly, its purposes and retention in your cookie policy.
  • Sign a data processing agreement with Cibleclic and check how email remarketing obtains a valid legal basis for each address.
Compliance

Uzerly and the GDPR

Uzerly is classified as “Analytics”. 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
Consent (Art. 6(1)(a) GDPR and Art. 5(3) ePrivacy Directive); Cibleclic is registered as IAB TCF vendor 963 with consent as the only legal basis

Impact assessment (DPIA)

A DPIA is recommended when Uzerly is used at scale, because it combines cross-session tracking, profiling of purchase intent and, for email remarketing, the link between browsing and an identified email address. Check the consent flow for each tag, the retention periods, the role of Cibleclic (processor or joint controller) and the legal basis for sending remarketing emails.

The script is served from an advertiser-specific subdomain of userly.net, for example 1234.userly.net/cl.js. Cibleclic also declares per-advertiser subdomains of userly.fr in its device storage disclosure.

Cibleclic declares an identifier named us_dt kept in web storage on the advertiser's site. Its Global Vendor List entry gives a maximum cookie lifetime of about six months.
