Information Nisu receives
When you visit Nisu, our hosting provider may process standard request information such as IP address, user agent, requested path, timestamp and security signals. We use Cloudflare Workers to deliver the site and operate its infrastructure logs. We do not run an account system or newsletter signup.
Embedded games
A game iframe is created only after you press its load button. Game files are served from s.nisu.io, a separate origin under the same Nisu domain. A game engine may use browser storage for preferences or saves. Those behaviors vary by game and can be cleared through your browser’s site-data controls.
Nisu listens only for a narrow optional ready message from that origin. The parent page verifies the origin, iframe window and game slug before accepting it.
Local device features
The site may use the Clipboard API when you press Copy link or Copy embed, the Web Share API when you press Share game and the Fullscreen API when you request fullscreen. These actions occur only after your explicit interaction.
My 9 Games
Your private grid draft and language preference are stored in your browser. Searching sends the game title to our server and IGDB; search results may be cached for one day. A cover you upload stays on your device until you create a share link. Downloading an image does not publish it.
Creating a share link uploads your selected games, optional name, notes, cover images and a preview. Anyone with the link can view them. Cards remain available until deleted or removed under our terms. You can delete a card with its private deletion key; save that key if you plan to change devices. Social services may keep their own cached previews after deletion. If you opt into community trends, verified game choices contribute to aggregate rankings. We temporarily keep a daily salted hash of the requesting IP for publishing limits; it is not part of the public card and expires from active limits after an hour, with expired records cleaned during publishing.
Krillion daily companion
Checking an answer sends that text to Nisu’s lookup endpoint for the current official list. We do not save answer inputs in our application database or send them to Google Analytics. Hint levels, prompt numbers and listed/not-found results are measured without answer text. Copied prompt links contain only a puzzle date and prompt number; they do not publish your answer. Normal hosting request metadata may still be logged.
Analytics
Nisu uses Google Analytics 4 by default to measure page visits and interactions, including My 9 Games actions such as image downloads and successful sharing. Analytics cookies may be stored when you visit; there is no on-site analytics permission prompt. You can manage cookies and tracking through your browser settings. My 9 Games excludes game names, personal notes, search text, card IDs and deletion keys from its analytics events, and strips query strings and card IDs from measured page URLs.
Advertising
The home page, guide listings, guides, game pages and Krillion answer tool include Adsterra banners hosted in separate-origin iframes. The ad provider may process IP addresses, browser information, cookies and advertising identifiers to deliver and measure ads. Nisu does not send guide search inputs or tool results to the ad iframe. Manage third-party cookies and tracking through your browser settings; the analytics settings described above are separate from advertising. See Adsterra’s privacy policy for the provider’s practices.
Content pages also load Adsterra Popunder advertising from abscloud.org in the main page. A page interaction may open an advertising window or tab. The provider may process network and browser information and use cookies or similar storage. Adsterra manages display frequency; Nisu does not impose a separate browser-storage frequency limit. Embedded game pages and legal pages do not load Popunder.
If you email contact@nisu.io, we receive the address, message and attachments you choose to send. We use that information to respond to the request and retain it only as reasonably necessary for the conversation, safety, rights or recordkeeping.
Children and adult content
Nisu labels mature entries before their iframe loads. The adults-only title requires an 18+ confirmation button. This is a content boundary, not identity verification. People under 18 must not access that entry.
