1. Cookies and similar technologies
Cookies are small pieces of information stored by a website in a browser. This policy also covers local storage and similar technologies used for the same purposes.
2. Essential storage currently used
- bcg_consent · Provider: BCG · Type: first-party cookie (version 2) · Purpose: remember analytics and marketing choices and the time of selection · Duration: 180 days after selection, or until deleted
- This item remembers your accept or reject choice; it does not itself enable optional tracking.
3. Analytics cookies
These technologies help measure site usage and performance. They are not currently used. If BCG later connects an analytics tool such as Google Analytics, it will run only after analytics consent. If you reject analytics, you are also excluded from the cookieless visit statistics below.
4. Marketing cookies
These technologies may measure advertising performance and consultation conversions or support relevant advertising. They are currently inactive and will run only after marketing consent.
5. Cookieless visit statistics
To improve this website, BCG keeps its own visit statistics without cookies or device identifiers.
- Purpose: to understand which pages are read, from which countries, channels (search, search ads, AI services, social, email and so on) and devices visitors arrive, and which pages lead to consultation requests and newsletter signups, so that we can improve our content and site structure.
- How: BCG’s server counts visits when it delivers a page. No new cookie, local storage, device identifier or tracking script is stored or run, and no third-party analytics tool such as Google Analytics is used.
- Counting unique visitors: to count the same visitor only once a day, the first part of the IP address (the first three blocks of an IPv4 address, the first 48 bits of an IPv6 address) and the browser information (User-Agent) are turned into a one-way value (hash) together with a random value created anew every day. This value is used only in server memory — to remove duplicates within the day, to separate visits after 30 minutes without activity and for the last-30-minutes realtime view (at most 48 hours) — and the random value is discarded every day and never stored. Visits on different days or on other websites therefore cannot be linked, and a person who returns on another day is counted as a new visitor.
- What is stored: daily and hourly totals only (Korea time) — visitors, visits (a new visit starts after 30 minutes without activity), page views, visits that viewed only one page, and the total time between page views. These totals are broken down by page address (without search terms or query parameters), entry and exit page, the referring site’s domain and acquisition channel, campaign tags (utm_source, utm_medium, utm_campaign; values containing an email address or long numbers are discarded), the country, region and city estimated by Cloudflare from the IP address, device type (desktop, mobile, tablet), browser and operating system name (without versions) and browser language. Consultation requests, newsletter signup requests and requests classified as automated (bots) are also counted.
- What is not stored: IP addresses, the hash and random value above, the raw browser information, the full address of the previous page, search terms, form contents, email addresses or anything else that could identify you or reconstruct one visitor’s path. Regions and cities with fewer than three visitors are not shown in the administration screens.
- Retention: daily totals are deleted automatically after 13 months. Website security and access logs are separate from these statistics and are kept for the period stated in the Privacy Policy (Retention).
- How to opt out: if you reject ‘Analytics cookies’ or choose ‘Reject optional’ in ‘Cookie settings’ at the bottom of each page, your visits and requests are not counted and no hash is made while that choice is stored. The choice is remembered for 180 days in the bcg_consent item described in this policy; no new cookie is created for these statistics. Visits made before any choice are counted.
- Use: only authorised BCG staff can see the totals in the administration screens. They are not shared with third parties or used for advertising.
6. Acquisition source of consultation and newsletter requests
To judge the effectiveness of advertising and content, BCG records how you found this website when you send a consultation or newsletter request.
- What is recorded: when and on which page you first arrived (without search terms or query parameters), the referring site’s domain (for example google.com or chatgpt.com — never the full address or search terms), campaign tags on the link (utm_source, utm_medium, utm_campaign, utm_term, utm_content), the names of ad click parameters (such as gclid — never their values) and the resulting category (for example Naver search, search ads, AI assistant, social, direct). If you arrive again through another route in the same tab, the latest route is recorded too.
- How: the information is kept only in the browser tab’s session storage (sessionStorage, item bcg_attribution); no cookie is created. It is deleted when the tab is closed and is sent to BCG only with a consultation or newsletter request.
- Use and retention: the acquisition source received with a consultation request is kept for the same period as that inquiry and used by authorised staff only to handle the inquiry and to judge advertising effectiveness. For newsletter requests it is not stored with the subscription; it is only added to daily totals.
- How to opt out: if you reject ‘Analytics cookies’ or choose ‘Reject optional’ in ‘Cookie settings’ at the bottom of each page, nothing is stored and a request carries only the domain of the site you came from immediately before the form page.
7. Managing consent
On your first visit, choose ‘Accept all’, ‘Reject optional’ or ‘Cookie settings’. You can later change or withdraw your choice using the ‘Cookie settings’ button in the page footer. You may also clear storage through your browser.
8. Changes and contact
If providers or purposes change, this policy will be updated and fresh consent requested where required. Contact: privacy@bcgmed.com
