Privacy policy
Last updated: October 12, 2026 · English translation: October 20, 2026
This policy applies to the Niwatoko Lab hub: its homepage, category introductions, operator information and contact pages. For game answers and room data, see the separate policies for Party Games and Hoshi no Shirube (Japanese).
Information when you browse
We use Google Firebase Hosting to deliver this site. The provider may process IP addresses, browser information and access times to deliver and secure the service. No registration is required to browse the hub.
Contact information
We use your inquiry category, reply email address and message to respond, investigate bugs and handle requests about rights or personal information. Do not send unnecessary personal or confidential information.
Our form uses FormSubmit to forward your submission to the operator's Gmail. Submission opens an external confirmation page, which may use cookies for spam prevention. See the FormSubmit privacy policy. Its retention period is separate from that of the emails we receive. We retain inquiries as needed to respond and keep records, and delete information when it is no longer needed. You can request access, correction or deletion through the same contact form.
Analytics
Only with your consent, we use Google Analytics 4 and cookies to analyze page views, referrals, device information, approximate regions and game starts. We do not send player names, answers, room codes or quiz inputs. Analytics cookies expire after 90 days. You can decline or change your choice using Analytics settings at the bottom of the page or in the menu. Declining does not prevent you from playing. Game-start counts reflect starts by consenting hosts, not all plays.
Advertising and cookies
We currently do not load Google AdSense or H5 Games Ads ad-serving scripts.
If advertising begins, third-party providers such as Google may use cookies, web beacons and IP addresses for ad delivery, measurement and fraud prevention. Google and its partners may use advertising cookies to display ads based on previous visits to this and other websites. Before serving ads, we will update this policy and implement the notices and consent mechanisms required for the relevant regions.
You can disable personalized advertising in Google My Ad Center. For other providers, see Your Ad Choices. You can manage or delete cookies in your browser. These settings do not remove all ads.
