Datarize
Datarize is a South Korean AI personalization platform that tracks visitor behaviour with cookies and JavaScript tags to deliver product recommendations, segmentation and conversion attribution. Under GDPR and ePrivacy, prior consent is mandatory before any tracking is loaded.
What does Datarize do?
What is Datarize
Datarize is an AI driven personalization and conversion optimization platform headquartered in Seoul, South Korea. It analyses visitor behaviour in real time to deliver product recommendations, dynamic banners, search ranking and email triggers tailored to each user.
Cookies and data collected
The Datarize JavaScript tag drops first party cookies and writes identifiers to local storage to recognize visitors across sessions and devices. It collects clickstream events, product views, cart and purchase data, IP address, user agent, screen size and approximate location.
GDPR and ePrivacy implications
Datarize is a marketing and personalization tool that goes well beyond what is strictly necessary for site delivery. Both Article 5(3) of the ePrivacy Directive and Article 6(1)(a) GDPR require prior, informed and granular consent before the tag is loaded or any identifier is read or written.
International data transfers
Datarize is a Korean company, so personal data leaves the EEA. South Korea has a partial adequacy decision from the European Commission (December 2021) that covers commercial data, but transfers should still be documented in the records of processing and supported by a Transfer Impact Assessment, especially if US sub processors are involved.
Implementing consent correctly
Block the Datarize script and any associated calls until the visitor opts in to the personalization or marketing category in your CMP. On withdrawal, clear all Datarize cookies, revoke local storage identifiers and stop sending events. Document the consent timestamp and scope as proof of consent.
Practical compliance steps
Sign a data processing agreement and SCC where required, restrict the data fields sent to Datarize, set short retention periods, conduct a DPIA, list Datarize transparently in your privacy and cookie policies and audit the cookies actually written from a clean test browser.
Datarize and the GDPR
Datarize 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
- Consent (Art. 6(1)(a) GDPR and Art. 5(3) ePrivacy Directive) is required because Datarize sets non essential cookies and creates behavioural profiles for personalization and marketing.
- Risk level
- high
- Applicable regulations
- GDPR, ePrivacy Directive, CCPA/CPRA, PIPA (South Korea Personal Information Protection Act)
Impact assessment (DPIA)
A DPIA is strongly recommended because Datarize performs systematic monitoring of visitor behaviour, builds individual profiles and powers automated decisions for personalization. Document the data flows, retention periods, and the international transfer to South Korea.
Sample text for your banner
We use Datarize to personalize products and recommendations. This installs cookies and transfers data to Datarize (South Korea). You can refuse personalization cookies at any time.
What Datarize sets and contacts
- Tracking method
- JavaScript tag for AI personalization, behavioural tracking and conversion attribution; collects clickstream, product views, cart events and uses cookies plus local storage to identify visitors across sessions
- Server location
- South Korea (Datarize headquarters in Seoul) with cloud regions for international clients
- Data transferred outside the EU
- Personal data is transferred to Datarize servers outside the EEA (notably South Korea). South Korea benefits from a partial EU adequacy decision (2022) for the private sector, but a Transfer Impact Assessment is still recommended. Standard Contractual Clauses (SCC) are typically required for any data routed via US sub processors.

Frequently asked questions about Datarize
Can't find your question? Write to us, we answer fast.
What cookies does Datarize set?
Datarize sets first party cookies and writes identifiers in local storage to recognize visitors across sessions and devices. The exact names vary, but they typically store a visitor ID, session ID and behavioural attributes used for personalization.
Is consent required for Datarize?
Yes. Datarize is a personalization and marketing tracker that goes beyond strictly necessary. Prior, granular and revocable consent is mandatory under Article 5(3) of the ePrivacy Directive and Article 6(1)(a) GDPR before the script may load.
What is the legal basis for Datarize?
The only valid legal basis for Datarize is consent (Art. 6(1)(a) GDPR). Legitimate interest does not apply because the processing creates behavioural profiles for marketing optimization.
Are there transfers outside the EEA?
Yes, data is transferred to Datarize servers in South Korea. South Korea benefits from a partial adequacy decision since December 2021, but Standard Contractual Clauses and a Transfer Impact Assessment may still be required if US sub processors are involved.
Is a DPIA required?
A DPIA is strongly recommended because Datarize performs systematic monitoring of visitors, builds individual profiles and powers automated personalization decisions, all of which are listed as high risk by EU data protection authorities.
How do I implement Datarize compliantly?
Block the script by default, load it only after consent in the personalization or marketing category, sign a DPA and SCC where needed, document Datarize in your policies, set short retention, restrict the data fields sent and audit cookies regularly.
Are there alternatives to Datarize?
European personalization vendors include Kameleoon, AB Tasty, Webtrekk and Dynamic Yield (Mastercard). Self hosted approaches like Open CMP based recommendation engines or first party only segmentation reduce data transfers.
How do I update the cookie policy?
Add Datarize to the personalization or marketing category, list each first party cookie name (visitor ID, session ID), provider (Datarize Inc., South Korea), purpose, retention and a link to the Datarize privacy policy. Refresh after every Datarize integration update.
