JACKLIST
JACKLIST is a web design company in Osaka, Japan, founded in 2015, that builds and hosts websites for small businesses. Sites made on its platform call api.jacklist.jp for banners, maps and translation widgets, which is what technology scanners detect. The platform itself serves the website, so it does not need consent, but embedded Google Maps or Google Translate do.
What does JACKLIST do?
What is JACKLIST?
JACKLIST Co., Ltd. (Kabushiki Kaisha JACKLIST) is a web design and branding company based in Kita-ku, Osaka, Japan. It was founded in November 2015 and offers website production, graphic design, branding and system development, mainly for small and medium-sized businesses such as shops, restaurants, hotels, clinics and schools. Besides custom sites, JACKLIST has operated its own hosted website platform; its interface calls these sites "homepy" and offers a JACKLIST ID that lets users log in to every site built by JACKLIST.
How JACKLIST appears on a website
Sites built on the JACKLIST platform define a JavaScript variable named homepage_api_url pointing to api.jacklist.jp and load resources from that server: a banner script, a responsive Google Maps embed (map_responsive.php) and a Google Translate wrapper (googleTrans.js). Technology scanners detect JACKLIST through this variable or the api.jacklist.jp script address. Some client sites built on the platform also load third-party scripts such as the Kakao SDK, used in Korea, or components from zeroweb.cloud. The JACKLIST server is hosted on Amazon Web Services in Tokyo.
Cookies and personal data
No JACKLIST cookie is publicly documented, so none is listed here. Loading resources from api.jacklist.jp sends the visitor's IP address and browser data to that server. Sites with member features collect the data entered by users, such as name, email address, phone number and booking or order details, and the shared JACKLIST ID links accounts across sites built by the agency. Embedded Google Maps and Google Translate send data to Google and may set Google cookies.
GDPR and consent
Serving the pages and their functional scripts is part of operating the website and does not require consent. Embedded Google Maps, Google Translate or social SDKs are optional third-party services: under the ePrivacy rules they should be loaded only after consent. Japan benefits from an EU adequacy decision, so data held by JACKLIST in Japan can be received without additional transfer tools, while Google services involve transfers to the United States.
Practical steps
- Ask JACKLIST which cookies and data its platform uses, and list them in your privacy notice.
- Load Google Maps, Google Translate and any social SDK only after consent, or replace them with a static map and link.
- If you use member accounts, explain the shared JACKLIST ID to users.
- Agree in writing on JACKLIST's role as service provider and on data security.
JACKLIST and the GDPR
- Legal basis
- Legitimate interest (Art. 6(1)(f) GDPR) for operating the website; consent (Art. 5(3) ePrivacy Directive) for optional embedded third-party services such as Google Maps or Google Translate
- Risk level
- low
- Applicable regulations
- GDPR, ePrivacy Directive, Japan Act on the Protection of Personal Information (APPI)
Impact assessment (DPIA)
A DPIA is not normally needed for a small business website on this platform. If member accounts, bookings or orders are enabled, document the data collected, the shared JACKLIST ID across sites, retention and the contract with JACKLIST, and check the consent flow for Google embeds.
