Privacy and data practices

FUSION LOUNGE accounts and posts

Reader accounts use Google sign-in. You choose a separate public nickname and agree to the guidelines before posting. We store an authentication identifier, nickname, interests, consent records, saved articles and opportunities, notifications and restriction records to provide membership features and operate safely. Authentication names and email addresses are not used in public Lounge profiles. Comments, questions and answers are public; displaying a membership number is optional. Saved lists and notifications are private to their owner. We do not send email notifications.

Leaving deletes your nickname, post text, saved lists and personal notifications. Ordinary account closure removes the Google account link, allowing registration again with the same Google account. Re-registration requires a new membership number and renewed acceptance of terms; old posts and saved information are not restored. If you leave during an active 7- or 30-day posting suspension, a matching value is retained until the original expiry. During an indefinite suspension, a matching hash to prevent evasion is retained for 180 days, after which the registration restriction based on it expires. Reports and moderator notes are excluded from viewing after 90 days. Expired information is deleted progressively on access, so physical deletion may be delayed. For enquiries about retained information, contact us through Contact. For posting rules and moderation policies, see the Lounge guidelines.

Reading articles

Public articles and databases can be viewed without signing in. Site administration, editorial drafts, the inbox and detailed analytics are available only to the site owner. Approved company representatives can access only their own company's drafts and contract information in the corporate portal. The home page shows article rankings, not view counts. Owner sign-in uses ChatGPT authentication.

Forms and email

The contact form stores your reply email address, name, category, subject and message to handle your enquiry. Corporate-partner enquiries also store a company name, optional website, department or role, requested start date and proposed content for consultation and pre-contract checks. These are kept in the operator's private inbox and do not appear on public pages or in search. The corporate portal stores a fixed login ID and email for identity checks, company and representative verification, contract versions and consent, payment checks and service periods, and draft and review history to deliver corporate services securely. Representatives can view and edit only their linked company's information, with no access to the inbox or whole-site administration. Information is not used for advertising or sold to third parties. To request deletion, choose Deletion request in the same form and include your reference number. For spam prevention, a short-lived hash derived from the connection source is used for an approximately one-hour sending limit and removed during request processing after expiry. The IP address itself is not stored with enquiries. We do not send automatic replies or email newsletters.

Traffic statistics

We do not use external analytics or advertising trackers. A random first-party cookie (fi_daily_visit), valid until midnight Japan time, helps estimate daily page views and browsing devices. Daily article views are also stored for the home page's popular-articles ranking. We do not store reading histories linking people with articles, IP addresses or detailed device data in analytics. Signed-in owner visits and identified bots are excluded from article rankings. Identifiers used for deduplication are deleted at the next measurement after about two days; only daily totals are retained. Detailed statistics are private to the owner; public pages show ranking only. Article-specific counting began when that feature was added, and earlier site-wide totals are not used to infer rankings.

Company, project and opportunity databases also count daily views for each listing and clicks on official links. Search terms, email addresses, IP addresses and individual reading histories are not stored. Owners, previews and identified bots are excluded, and earlier figures are not estimated. Clicks do not represent applications or completed transactions. We also aggregate daily totals by page and route for featured articles, opportunities and internal links from articles to companies, projects and related information. Click measurement adds no identifying cookie and stores neither search filters nor individual navigation histories. Visitors are not identified across days.

3D図鑑では、日別・解説ページ別に表示、最初の操作、関連情報リンクの操作を各ページ表示につき1回まで集計します。流入元は限定したSNS・検索・直接流入の区分だけを保存し、完全な参照元URL、検索語、IPや個人の操作履歴は保存しません。所有者・プレビュー・識別できたボットは除外し、集計開始前の数字は推定しません。

External links

External sources, related sites and owner-configured social links are governed by their own terms and privacy policies. Opening an external link alone does not transfer this site's administrative data.

Managing saved information

The owner can unpublish or restore articles and download backups through administration. For enquiries about previously provided information, use the Contact.
