Privacy notice.

This notice explains how information is used when you visit Three.js Foundations Lab at www.threejslab.com, operated by JimakuAI in Japan.

Last updated: September 19, 2026. Questions or requests: json@jimaku.ai.

Visiting the site

You can explore the labs without creating an account. Vercel hosts and delivers this site. Website requests disclose technical information such as your IP address, requested URL, browser information, and request time to the hosting infrastructure. That information supports delivery, diagnostics, reliability, and abuse prevention. See Vercel's privacy notice for information about its services.

Demo settings and local storage

Some graph-editor and inspection demos store graph code, display preferences, or the current page URL in your browser's local storage. Other experiments keep temporary rendering, device-capability, or performance information in browser memory. Local storage can remain after you close a page. You can remove it by clearing this site's data in your browser; doing so may erase saved demo work and preferences.

Camera, microphone, and immersive demos

Selected demos offer camera, microphone, or AR/VR features after you activate their controls and grant the permissions your browser requires. Camera textures and the capture-permission experiments run in your browser. The site's demo code does not upload camera or microphone streams to JimakuAI. You can decline or revoke these permissions in your browser and close the demo to stop its session.

External assets and services

Some labs request fonts, models, media, or code from other providers, including Google Fonts, threejs.org, unpkg.com, cdn.skypack.dev, and cdn.jsdelivr.net. Loading these resources sends normal web-request information, including your IP address, to their hosts. The optional TSL Graph editor integration loads www.tsl-graph.xyz and can exchange graph and material content with that service when enabled. External links and GitHub issue pages are governed by their providers' own privacy practices.

Contacting us

If you email us, we receive your email address and the information you choose to include. We use it to respond to your question, investigate a problem, or discuss a sponsorship. Email is handled through our email service provider. Please do not send passwords, payment card details, or unnecessary sensitive information. GitHub issue reports are public.

Advertising and cookies

We are preparing to use Google AdSense to support free access to the labs. At the date above, the site contains publisher-verification information but does not load AdSense ad scripts or Google Analytics. A verification meta tag and ads.txt file do not themselves store advertising cookies.

When advertising is activated, Google and other participating advertising providers may use cookies, web beacons, IP addresses, and similar identifiers to deliver ads, measure performance, and prevent fraud. Advertising cookies can support personalized ads based on visits to this and other websites. We will update this notice and provide the required consent controls before activating advertising that needs them.

You can manage Google's personalized advertising through My Ad Center. Read how Google uses information from partner sites and Google's privacy policy. Choices for some other advertising providers are available through YourAdChoices. These settings do not necessarily prevent all advertising or all storage.

Your choices and requests

You can clear site storage, manage cookies, and revoke camera or microphone permissions through your browser. To ask about information JimakuAI holds about you or request access, correction, or deletion where applicable, email json@jimaku.ai. Some records may need to be retained to resolve an inquiry, maintain security, or meet applicable obligations. Hosting and external-service records are also subject to the relevant provider's practices. Service providers may process information outside your country.

Changes to this notice

We will revise this page when the site's data practices change and update the date above.
